Let’s take a lucky guess that you’re here today because you’ve heard a lot about cryptocurrencies and you want to get involved, right? If you’re a community person, Dogecoin mining might be the perfect start for you! Bitcoin was the first in 2009, and now there are hundreds of cryptocurrencies. These new coins (that operate on their own native blockchain) are called altcoins or alternative coins. One popular altcoin is Dogecoin. It can be bought, sold and traded, just like Bitcoin. It can also be mined! So, what is Dogecoin mining? You’ll know what hardware and what software you need to get started. You’ll also know whether or not Dogecoin mining is for you! So, where would you like to start? The beginning? Great choice. Let’s have a quick look at how Dogecoin got started. A (Very) Short History of Dogecoin In 2013, an Australian named Jackson Palmer and an American named Billy Markus became friends. They became friends because they both liked cryptocurrencies. However, they also thought the whole thing was getting too serious so they decided to create their own. Palmer and Markus wanted their coin to be more fun and more friendly than other crypto coins. They wanted people who wouldn’t normally care about crypto to get involved. They decided to use a popular meme as their mascot — a Shiba Inu dog. https://preview.redd.it/rymnyyz1iil31.png?width=303&format=png&auto=webp&s=f138e3fe56eef9c6b0e7f49b84fefc41fb83e5aa Dogecoin was launched on December 6th, 2013. Since then it has become popular because it’s playful and good-natured. Just like its mascot! Dogecoin has become well-known for its use in charitable acts and online tipping. In 2014, $50,000 worth of Dogecoin was donated to the Jamaican Bobsled Team so they could go to the Olympics. Dogecoin has also been used to build wells in Kenya. Isn’t that awesome! Users of social platforms – like Reddit – can use Dogecoin to tip or reward each other for posting good content. Dogecoin has the 27th largest market cap of any cryptocurrency. Note: A market cap (or market capitalization) is the total value of all coins on the market. So, Dogecoin is a popular altcoin, known for being fun, friendly and kind. It’s a coin with a dog on it! You love it already, don’t you? Next, I want to talk about how mining works… What is Mining? To understand mining, you first need to understand how cryptocurrencies work. Cryptocurrencies are peer-to-peer digital currencies. This means that they allow money to be transferred from one person to another without using a bank. Every cryptocurrency transaction is recorded on a huge digital database called a blockchain. The database is stored across thousands of computers called nodes. Nodes put together groups of new transactions and add them to the blockchain. These groups are called blocks. Each block of transactions has to be checked by all the nodes on the network before being added to the blockchain. If nodes didn’t check transactions, people could pretend that they have more money than they really do (I know I would!). Confirming transactions (mining) requires a lot of computer power and electricity so it’s quite expensive. Blockchains don’t have paid employees like banks, so they offer a reward to users who confirm transactions. The reward for confirming new transactions is new cryptocurrency. The process of being rewarded with new currency for confirming transactions is what we call “mining”! https://preview.redd.it/rcut2jx3iil31.png?width=598&format=png&auto=webp&s=8d78d41c764f4fe4e6386da4f40a66556a873b87 It is called mining because it’s a bit like digging for gold or diamonds. Instead of digging with a shovel for gold, you’re digging with your computer for crypto coins! Each cryptocurrency has its own blockchain. Different ways of mining new currency are used by different coins where different rewards are offered. So, how do you mine Dogecoin? What’s special about Dogecoin mining? Let’s see… What is Dogecoin Mining? Dogecoin mining is the process of being rewarded with new Dogecoin for checking transactions on the Dogecoin blockchain. Simple, right? Well no, it’s not quite that simple, nothing ever is! Mining Dogecoin is like a lottery. To play the lottery you have to do some work. Well, actually your computer (or node) has to do some work! This work involves the confirming and checking of transactions which I talked about in the last section. Lots of computers work on the same block of transactions at the same time but the only one can win the reward of new coins. The one that earns the new coins is the node that adds the new block of transactions to the old block of transactions. This is completed using complex mathematical equations. The node that solves the mathematical problem first wins! It can then attach the newly confirmed block of transactions to the rest of the blockchain. Most cryptocurrency mining happens this way. However, Dogecoin mining differs from other coins in several important areas. These areas are;
Algorithm: Each cryptocurrency has a set of rules for mining new currency. These rules are called a mining or hashing algorithm.
Block Time: This is the average length of time it takes for a new block of transactions to be checked and added to the blockchain.
Difficulty: This is a number that represents how hard it is to mine each new block of currency. You can use the difficulty number to work out how likely you are to win the mining lottery. Mining difficulty can go up or down depending on how many miners there are. The difficulty is also adjusted by the coin’s protocol to make sure that the block time stays the same.
Reward: This is the amount of new currency that is awarded to the miner of each new block.
Now, let’s compare how DogeCoin mining works compared to Litecoin and Bitcoin… Mining Comparison Bitcoin uses SHA-256 to guide the mining of new currency and the other two use Scrypt. This is an important difference because Scrypt mining needs a lot less power and is a lot quicker than SHA-256. This makes mining easier for miners with less powerful computers. Fans of Litecoin and Dogecoin think that they are fairer than Bitcoin because more people can mine them. Note: In 2014, Litecoin and Dogecoin merged mining. This means they made it possible to mine both coins in the same process. Dogecoin mining is now linked with Litecoin mining. It’s like two different football teams playing home games in the same stadium! Mining Dogecoin is a lot faster than mining Litecoin or Bitcoin. The block reward is much higher too! Don’t get too excited though (sorry!). Dogecoin is still worth a lot less than Bitcoin and Litecoin. A reward of ten thousand Dogecoin is worth less than thirty US Dollars. A reward of 12.5 Bitcoin is currently worth 86,391.63 US Dollars! However, it’s not as bad as it sounds. Dogecoin mining difficulty is more than one million times less than Bitcoin mining difficulty. This means you are much more likely to win the block reward when you mine Dogecoin. Now I’ve told you about what Dogecoin mining is and how it works, would you like to give it a try? Let’s see what you need to do to become a Dogecoin miner… How to Mine Dogecoin There are two ways to mine Dogecoin, solo (by yourself) or in a Dogecoin mining pool. Note: A Dogecoin pool is a group of users who share their computing power to increase the odds of winning the race to confirm transactions. When one of the nodes in a pool confirms a transaction, it divides the reward between the users of the pool equally. Dogecoin Mining: Solo vs Pool When you mine as a part of a Dogecoin pool, you have to pay fees. Also, when the pool mines a block you will only receive a small portion of the total reward. However, pools mine blocks much more often than solo miners. So, your chance of earning a reward (even though it is shared) is increased. This can provide you with a steady new supply of Dogecoin. If you choose to mine solo then you risk waiting a long time to confirm a transaction because there is a lot of competition. It could be weeks or even months before you mine your first block! However, when you do win, the whole reward will be yours. You won’t have to share it or pay any fees. As a beginner, I would recommend joining a Dogecoin pool. This way you won’t have to wait as long to mine your first block of new currency. You’ll also feel like you’re part of the community and that’s what Dogecoin is all about! What You Need To Start Mining Dogecoin Before you start Dogecoin mining, you’ll need a few basics. They are;
A PC with either Windows, OS X or Linux operating system.
An internet connection
A Shiba Inu puppy (just kidding!)
You’ll also need somewhere to keep the Dogecoin you mine. Go to Dogecoin’s homepage and download a wallet. Note: A wallet is like an email account. It has a public address for sending/receiving Dogecoin and a private key to access them. Your private keys are like your email’s password. Private keys are very important and need to be kept completely secure. There are two different types; a light wallet and a full wallet. To mine Dogecoin, you’ll need the full wallet. It’s called Dogecoin Core. Now that you’ve got a wallet, you need some software and hardware. Dogecoin Mining Hardware You can mine Dogecoin with;
Your PC’s CPU: The CPU in your PC is probably powerful enough to mine Dogecoin. However, it is not recommended. Mining can cause less powerful computers to overheat which causes damage.
A GPU: GPUs (or graphics cards) are used to improve computer graphics but they can also be used to mine Dogecoin. There are plenty of GPUs to choose from but here are a few to get you started;SAPPHIRE Pulse Radeon RX 580 ($426.98)Nvidia GeForce GTX ($579.99)ASUS RX Vega 64 ($944.90)
A Scrypt ASIC Miner: This is a piece of hardware designed to do one job only. Scrypt ASIC miners are programmed to mine scrypt based currencies like Litecoin and Dogecoin. ASIC miners are very powerful. They are also very expensive, very loud and can get very hot! Here’s a few for you to check out;Innosilicon A2 Terminator ($760)Bitmain Antminer L3 ($1,649)BW L21 Scrypt Miner ($7,700)
Dogecoin Mining Software Whether you’re mining with an ASIC, a GPU or a CPU, you’ll need some software to go with it. You should try to use the software that works best with the hardware you’re using. Here’s a short list of the best free software for each choice of mining hardware;
CPU: If you just want to give mining a quick try, using your computer’s CPU will work fine. The only software I would recommend for mining using a CPU only is CPU miner which you can download for free here.
GPU: If you mine with a GPU there are more software options. Here are a few to check out;CudaMiner– Works best with Nvidia products.CGminer– Works with most GPU hardware.EasyMiner– User-friendly, so it’s good for beginners.
Scrypt ASIC miner:MultiMiner– Great for mining scrypt based currencies like Litecoin and Dogecoin. It can also be used to mine SHA-256 currencies like Bitcoin.CGminer and EasyMiner can also be used with ASIC miners.
Recommendations You’re a beginner, so keep it simple! When you first start mining Dogecoin I would recommend using a GPU like the Radeon RX 580 with EasyMiner software. Then I would recommend joining a Dogecoin mining pool. The best pools to join are multi-currency pools like Multipool or AikaPool. If you want to mine Dogecoin but don’t want to invest in all the tech, there is one other option… Dogecoin Cloud Mining Cloud mining is mining without mining! Put simply, you rent computer power from a huge data center for a monthly or yearly fee. The Dogecoin is mined at the center and then your share is sent to you. All you need to cloud mine Dogecoin is a Dogecoin wallet. Then choose a cloud mining pool to join. Eobot, Nice Hash and Genesis Mining all offer Scrypt-based cloud mining for a monthly fee. There are pros and cons to Dogecoin cloud mining; The Pros
It’s cheaper than setting up your own mining operation. There’s also no hot, noisy hardware lying around the house!
As a beginner, there isn’t a lot of technical stuff to think about.
You get a steady supply of new currency every month.
Cloud mining pools don’t share much information about themselves and how they work. It can be hard to work out if a cloud mining contract is a good value for money.
You are only renting computer power. If the price of Dogecoin goes down, you will still have to pay the same amount for something that is worthless.
Dogecoin pools have fixed contracts. The world of crypto can change very quickly. You could be stuck with an unprofitable contract for two years!
It’s no fun letting someone else do the mining for you!
Now you know about all the different ways to mine Dogecoin we can ask the big question, can you make tons of money mining Dogecoin? So, Is Dogecoin Mining Profitable? The short answer is, not really. Dogecoin mining is not going to make you a crypto billionaire overnight. One Dogecoin is worth 0.002777 US Dollars. If you choose to mine Dogecoin solo, it will be difficult to make a profit. You will probably spend more money on electricity and hardware than you will make from Dogecoin mining. Even if you choose a Dogecoin pool or a cloud pool your profits will be small. However, if you think I am telling you to not mine Dogecoin, then you’re WRONG! Of course, I think you should mine Dogecoin! But why? Seriously… Well, you should mine Dogecoin because it’s fun and you want to be a part of the Dogecoin family. Cryptocurrency is going to change the world and you want to be part of that change, right? Mining Dogecoin is a great way to get involved. Dogecoin is the coin that puts a smile on people’s faces. By mining Dogecoin you’ll be supporting all the good work its community does. You’ll learn about mining from the friendliest gang in crypto. And who knows? In a few years, the Dogecoin you mine now could be worth thousands or even millions! In 2010, Bitcoin was worthless. Think about that! Only you can choose whether to mine Dogecoin or not. You now know everything you need to know to make your choice. The future is here. So, what are you going to do?
New people please read this. [upvote for visibility please]
I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks
Prices include shipping, taxes, and discounts when available.

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.

Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority. The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin. Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value. Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers. The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone. Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency. The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies. Bitcoin creator, Satoshi Nakamoto What is the Mining of bitcoin? Technical details : During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized. The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network. Material : In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU. Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time. For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency. A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people. The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins. The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7. Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs. There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology. Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable. Software : There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains. Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner. If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.
Bitcoin mining OK, Litecoin not so much... System Freeze's
I'm not sure how much detail to include here, so here goes: GPU: Dual 7970 Drivers: 13.1 & 2.8 APP SDK OS: Windows 7 64 bit I pull 1.3 Mhz easily. No OC. I'm not at home right now, so I can't pull my cgminer options (thread concurrency, shaders, etc) but I took them directly from the mining comparison website. My temps stay around 68-72 C I use powered risers. Problem: After starting mining I can run for 1 - 4 hours before my system will freeze. It's an incremental freeze, within a few seconds the main window locks up, seconds later I cannot change windows, then the mouse will lock up. Then that's it. No crash, no BSOD. It just hangs. I watched my pool's site to see if it was just brain dead but still running, no dice my hash rate drops to zero. The only way out is a hard reboot (power button). When I mine bitcoin I don't have this experience. I understand, oranges and apples. After some digging I'm leaning on this being a mem timing issue. Does anyone have this experience? Edit: Cgminer settings: --scrypt -o stratum+blah -u uname -p pass --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256 Edit #2: I'm going to toss a bounty to the best answer
So, I'm running a fresh install of CentOS 6.5 x64. I'm attempting to get everything working up to the maximum potential. I have started by following the following guide very closely: http://truemetal.org/universe/blog/2013/05/howto-cgminer-bitcoin-litecoin-etc-amd-driver-install-on-centos/ Sadly, everything works, but I seem to be stymied by a less than ideal hash rate of around 590 - 610 Khash/sec. I have started with the recommended settings on the Mining Hardware comparison. According to that site, I should be getting ~720 Khash/sec. Here is my current command line: cgminer --scrypt -o stratum+tcp://poolurl.com:3334 -u username -p password --gpu-powertune 20 --thread-concurrency 22272 -w 256 -I 13 -g 2 -d 1 I determined thread-concurency by running cgminer with no tuning options and pulling the value from the .bin file. I have also tried various combinations of adjusting thread-concurrency, intensity ( -I 18, -I 20, -I 12, -I 13 ), GPU threads ( -g 1 or -g 2 ), adjusting work size between 512 and 256, and either manually specifying --gpu-engine and --gpu-memclock, or choosing --auto-gpu. Sadly, nothing gets me much above 600 Khash on this. :(
These are just a couple of the discoveries I've made in my first couple days of mining. Most of these will be things that are likely obvious to experienced miners, but can cause some confusion for new shibes like myself. So maybe someone else will be able to benefit from my mistakes.
Bitcoin (and several others) uses SHA-256 for its hashing algorithm. Dogecoin (and some others, most notably Litecoin) uses scrypt. The two are not compatible and, in fact, there is a huge discrepency in the hashes/second rates. For instance, my Radeon HD 4850 card runs at about 70 Mh/s for SHA-256, but only 100 Kh/s (0.1 Mh/s) for scrypt. I've gathered that this has something to do with scrypt requiring more computations per hash. When looking at Kh/s or Mh/s numbers, it is very important to know which algorithm is being used, otherwise this can lead to some confusion, for instance, when comparing thesesheets.
GUIMiner does NOT support scrypt (There is a separate program called GUIMiner-scrypt for that). However, GUIMiner will let you connect to a Dogecoin pool and even report acceptedshares all while running on the SHA-256 algorithm, which is useless for Dogecoins. I'm still not sure exactly why this happens, but it led to me wasting about a day of running my GPU with nothing to show for it, since I was convinced that if shares were being accepted, it must actually be doing something right.
cgminer can take a LOT of work to set up. First of all, there are several versions of cgminer, each with its own quirks, some with windows binaries available, and some you have to build yourself. Also, GPU mining is not supported past version 3.7.2. It took me a while and several failures at building/setting up different versions before I noticed the link on the right side of /dogemining that goes directly to a windows binary of cgminer 3.7.2. Much easier. I've heard that many consider cgminer to be superior to GUIMiner-scrypt, but since I can't get GUIMiner-scrypt to run, I can't say for myself.
Much of mining seems to be trial and error: finding the software and configuration that works for your specific setup. Every card will behave differently, and even though there's tons of information out there to help, it really just comes down to trying a bunch of things and finding out what works.
I'm happy to say I've just seen my first hundred Doge from mining, and I'm excited to see how far I can go (to the moon?). I'm sure I'm still mistaken about lots of things, and if I missed anything here, let me know.
PC GPU's Can Mine Cryptocurrencies when not Gaming. Consoles Sit Useless
You've invested money building a slick gaming PC? Unbeknownst to you, you've probably inadvertently built a great PC for mining Crypto currencies like Dogecoin, Litecoin, Darkcoin, Vertcoin, and thousands of others. You can convert electricity into coins, and if you want you can trade these coins for Bitcoin or even USD. New coins are launched everyday and during the first few hours/days of a coin launch it is easy to acquire a large share. If you do your research you can potentially get a large share of a coin that will build value. For reference a single R9 270 card can produce ~1000 Dogecoins a day. Not much in USD value, but an easy way to dip your feet into a new hobby that utilizes hardware you've already invested in. You can mine whenever you aren't gaming. I've been a PC buildegamer my whole life. I got into Crypto mining this January, and at first I was nervous about damaging components by running them so hard continuously, at rather high temperatures (80C). Well its been 6 months and there are no hardware stability issues. 6 Cards running at ~80C 24/7 for 6months. They run flawlessly. Thermal paste could probably be re-applied now. The point is, if you have a clean PC and know how to troubleshoot hardware you aren't going to damage your computer or graphics cards. Its been argued that gaming stresses the GPU's more because the load is changing high-low, whereas mining is constant high. Anyways you want to know: How can I start mining? There are so many coins where do I start? Dogecoin is the easiest coin to start mining (not necessarily most profitable) so we will start there and after you learn with Doge you can expand to new horizons.
Register at your pool. Create a worker. Go to the "getting started page" and copy the host "stratum+tcp://stratum.rapidhash.net" and port number "3333" and then you can enter your workepassword details and start mining. You can then carefully adjust your parameters to increase your mining speed. Increasing intensity too high can crash your card. Check out the configuration settings in this guide for approximately optimal settings for your GPU If this sounds like a lot of work then this might not be the hobby for you. If you are interested about maximizing the potential of your gaming hardware and want to enter a new and engaging hobby, this might be the right place to start. Its also another thing that PC gamers can do that Consoles really fail at. Now get into those mines and start digging!
from here and it would be running with roundabout 950 Kh/s whui, however, my workers nor my wallet nor my Dashboard would be updating after 8 hours of "mining" today: http://i.imgur.com/QoEpuni.png I didnt get any valid shares, nothing. I have no idea what I did do wrong. Can somebody please help me? I am out of options.
[modpost] Possible wiki page, something I call "All about miners," covering things from basic terminology to miner config files and overclocking.
What is a miner? A miner is a computer set up to solve cryptographic hashes in the litecoin network. Once a clump of these hashes, or a block, is mined, litecoins pop out! It's like opening a box of chocolates, except you know what you're gonna get :) Miners also handle transaction confirmations, making sure no single coin is double-spent. Setting up your computer to be a miner What kind of computer do I need? Optimally, you'd have a good power supply and a couple decent Radeon/ATI/AMD graphics cards. Because of litecoin's hash algorithm, the gap between mining with graphics cards and processors is less than with most other cryptocurrencies, meaning that mining with some desktop processors may be worth it after electricity costs. Note that mining with laptops is not recommended because of the heat generated by mining, and mining with NVIDIA graphics cards may not be worth the cost. How do I know if litecoin mining will be profitable for me? First, check how fast you'll be mining with your hardware, how many litecoins you'll mine in a day, and how much litecoins are worth. Now, multiply the number of litecoins per day by their worth. Then, find out the power draw of your hardware, and calculate energy cost. Then finish by subtract energy cost from your daily earnings. If your number is positive, you're making that much money per day. If negative, you're losing money. Keep in mind that the worth of litecoins goes up/down, and you have to earn the cost of your hardware before you churn a profit. Mining difficulty also goes up/down, depending on how many people are mining how fast in relation to how many litecoins are supposed to be generated how fast. See the economics(coming soon) post for more info. Okay, I did all that. How do I start? All you have to do is download a program and change some settings (later in the guide), and you're ready to go. If you're comfortable with configurations and the command line, Reaper and cgminer are your best friends. Otherwise, GUIMiner-scrypt is right for you. If you want to mine on your processor, download the "batteries included" miner via this link and setup should be relatively self-explanatory. Do I mine alone? Due to the difficulty of mining, we recommend that you mine with a pool where multiple people mine together. Visit your pool's about or help page for proper miner settings, which we're about to get to in-depth! Under the hood Configuring your miner (aka the hard part) Before we get started, you should become familiar with these terms:
host: Your pools website
port: The internet port your computer uses to connect to your pool
worker: Anything that mines is a worker. Just a way for you and your pool to keep track of what's mining how.
user: In mining programs, the user is the name of your worker, which by default tends to be poolusername.1 or poolusername_1, _2, etc.
pass: Password for your worker, NOT your pool password. This can usually be anything.
None of those will have any affect on how fast you mine. The settings that we'll be focusing on are:
worksize: Exactly what it sounds like
thread-concurrency: Setting that involves computations happening simultaneously
vectors: Involves how memory is used
aggression/intensity: How aggressively your computer mines
threads_per_gpu: How many threads of data to process on a GPU, like threads of a CPU. Anything beyond 1 usually doesn't increase hashrate on modern cards.
device: First GPU is device 0, second is device 1, etc.
If you're using GUIMiner-scrypt, there are default settings for different cards (lower right dropdown). I'm mining on a 7870. Here is what it looks like for me. You can follow along with the rest of this guide to optimize your settings. GUIMiner-scrypt is just a GUI to cgminer and reaper anyways. If you are using a command-line miner, like reaper and cgminer, I recommend you download and isntall Notepad++ or SublimeText if on Linux. Reaper is currently considered to be the best tool for mining. After you unzip your downloaded file, in the folder you'll find reaper.conf. It should look something like this:
As you see, my thread concurrency is slightly different from the default of GUIMiner-scrypt. I found that this concurrency gives me the best hashrate! NOTE: I do not use cgminer to mine litecoin. If you plan on using cgminer, which offers more hardware-controlling settings, in the cgminer folder you will want to create a text file. Then, open that text file w/ Notepad++ or SublimeText, then Save As > cgminer.con > file type > all. This will save the file with the proper name and as the proper type. Note that cgminer does not support high concurrencies. For me, cgminer.conf would look something like:
You saw some settings similar to what we saw in Reaper's litecoin.conf. The other settings have to do with my card's clocks, voltage, and fan. This is covered in the overclocking section right below! Overclocking (aka the risky part) Okay, first off I'm not responsible if you cause damage to your parts. Please research safe overclock settings for your card. Second, don't be afraid. Modern hardware has many safety features in place that help prevent mayhem like me...lol jk this isn't a car insurance add. For your better understanding, become familiar with these terms:
Voltage/vddc: Amount of electrical current supplied to your card
Power Limit: Determines at what temperature your card throttles itself
Core Clock: Speed of your memory's core, similar to CPU core clocks
Memory Clock: Speed of GPU's GRAM, similar to RAM speed
Fan speed (%): Determines the RPM of your fan once your card reaches certain temperatures.
No one setting controls how effectively you mine; what matters most when it comes to clocks is the ratio between your core/memory clocks. Generally, a ratio of 0.7 or below is best. You will need to experiment. If you're using cgminer, you can control card settings from the conf file. However, if you aren't, I recommend using MSI Afterburner as your overclocking tool. You will need to unlock some settings. Using my cgminer settings, MSI Afterburner looks like this. I have found these settings to be the most stable while bringing me a high hashrate. Other people's optimum settings You can check the sidebar for the hardware comparison chart, but it is rarely updated and has huge sways in results. It is a good starting place. The mods of this subreddit will be putting together an updated, more accurate list in the near future. END I hope all things go smoothly for you and that you've learned a lot!

Hey there helpful shibes, I have a problem with my mining setup. Looking at this chart for litecoin mining: https://litecoin.info/Mining_hardware_comparison My 7870 should at least be getting me 300Kh/s depending on the version, I have the XFX Radeon HD 7870 Double Dissipation Black Edition. I have already done my fair share of googeling for solutions, and I have tried so far
Upgrading my GPU drivers to the latest version.
Reinstalling the latest version of CGminer.
Trying to put the intensity over 11 (But then I get HW problems.)
Also bitcoin mining using GUIminer worked perfectly getting me around 400Mh/s. Thanks in advance. Edit: Now using two threads and getting around 250Kh/s, still not perfect but a huge improvement.
