Hardware advice for a new miner
Hows it going reddit community, I've been lurking here continuously the last 12hrs and I wish I had found this place earlier. I've just bought my first rig, Made up of 3x SAPPHIRE HD 7970 3GB Vapor-X Ghz. I realize now that I should have just bought as many 7950s as I could, although I bought these at a killer price of £310 which is a fair bit cheaper than the rest of the British retailers. I'm confident resale value should stay fairly high so I'm not too worried about buying these premium cards. Motherboard is Gigabyte X79-UD3. I bought this mobo because it is able to run three GPUs at 16x/8x/8x. I've seen people using a cheaper motherboards which would run three GPUs at 16x/8x/4x or 8x/8x/4x, would I see any gain in kh/s from the extra bandwidth of this mobo? CPU is my current desktop machines Intel Core i7 with stock fan and also 8GB DDR3 from that system. I did not know about risers and stupidly did not order some, I can only really afford two at the moment but I'm sure that should suffice. I'm can't stop peeking out my window at the sound of a passing van hoping it is the Polish TNT driver who delivers my parcels... the wait continues - I'll be mining at give-me-ltc, see you guys around!
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

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.
Okay so I've had my ubuntu server storage/plex/torrents/ftp/website running for a few years now, and I always wanted to jump in to bitcoin but you know that never happened... especially with the current difficulty. Anyway on the weekend I ventured out and bought myself 2x 7950's and added them to my server. After a back up and fresh install of ubuntu server 13.10, with the current amd beta drivers, (and quick restore of all my previous settings bring the server back to its former glory) I started messing with cgminer settings and bla bla bla, and I've been testing different pools, and I've settled on coinhuntr over mine-litecoin (for some reason mine-litecoin just doesnt report the correct hash rate that cgminer is reporting... at least for me) and yeah its been only a few days and I've got 3 litecoins so far I'm pretty happy, mostly excited at how well its all just working for me, I mean I havn't completely maxed out the hash rate of the cards yet, they are sitting 1098 avg, but there is no impact on my server, plex still streams, deluge still downloads... flexget still flexgets, I can still ftp to my storage from uni, and yeah. only thing I'm working on is a init.d script to run at a delayed time (giving everything else the opportunity to boot before mining starts) in the even that power fails long enough and my ups goes out (its a 3000va ups so i dont think thats gonna happen any time soon :P ) but you know, my family that im still living with, dad understands that my server is best for the network when its on :P but yeah, thats sorta what I wanted to share and yeah, I suppose im welcoming myself to the community :P edit: I forgot to mention, My wallet Im keeping on an encrpyted ubuntu VM, and then that vm is kept on a true crypt drive and I have multiple usb's of this partition and you know, a pile of memorized paraphrases... yeah i know perhaps a bit over the top, but I've read so many horror stories of people loosing their bitcoins, can't say I want say the next 5 years of litecoin being taken from me... you know for example Anyone else got some over the top wallet protection stories?
Hey there! I just recently heard about crypto currency a few hours ago and I thought I might try to be a part of it! So this is my first day trying it (and my first day ever using Redit) So far I watch a few tutorials on what bitcoins are, how to set up a wallet, get a pool, ect. And after syncing the dogecoin wallet, i loaded my .bat and it's running with nut2pool but for some reason http://i.imgur.com/9OHTZYh.png it's been stuck at 0.0 Hashrate for a while. Every now and then it would go up to 69KH , but after 10 seconds go right down to 0.0 again. My setup: Intel I5 /// 12GB Ram /// Radeon HD 7950 Using cgminer-3.7.2 for windows 7 , and I have a 30mb time warner connection. Code: cgminer --scrypt -o stratum+tcp://dogeu.nut2pools.com:5585 -u -p -o stratum+tcp://dogus.nut2pools.com:5585 -u rikkusguardian.shadow -p flamesofel3 Am I doing something wrong?
I'm setting up a mining rig using 3-7950's, and have ran into a little bit of a road block. I've seen a few guides using xubuntu 12.10, but none with xubuntu 13.04. darth_bunny's guide cryptobadger's guide gentoo (bitcoin) I've tried the first 2 ways on fresh images, but for some reason X never starts...
aticonfig --adapter=0 --od-getclocks ERROR - X needs to be running to perform AMD Overdrive(TM) commands
Following the darth_bunny's guide way I built to 13.04 instead of 12.10
On a side note, whenever I plug the ATI cards in, video (connected to onboard), does not output. I'm guessing this is because the ATI cards are primary? It didn't bother me as I ssh in anyway. I also have some missing lib's when trying to run cgminer, but that is something to worry about later. Has anyone solved this on 13.04, or should I just downgrade to 12.10?
I've tried to set up doge mining with cgminer (only did some bitcoin mining before) following the wiki's/sidebar's tutorials but no matter what kind of settings I'm using in my bat file, the 7950 will stay at slightly below 15 Kh/s (and 50 °C). The barebones bat file looks as follows:
set GPU_MAX_ALLOC_PERCENT=100 set GPU_USE_SYNC_OBJECTS=1 cgminer.exe --scrypt -o mypool -u myuser.myworker -p mypassword -I 20
No matter what card-specific settings I add, the Kh/s doesn't change. I'm mining on dogehouse if that's in any case relevant. I'm also using Windows 7 x64 and Catalyst 13.12 drivers (updated from 13.8 to no avail). Any suggestions? Thanks! EDIT: I have fixed my problem. For some reason the bat file does not correctly set the intensity and reverts to the lowest (default?) value. Manually setting it to the desired value within cgminer by pressing g->i->20->enter gives me the desired Kh/s.
Hello guys, I am extremely new to this bitcoin mining and I had a couple of questions. My set up: 2 of HIS HD Radeon 7950s running at 800 MHz, 1250 memory clock cgminer 3.2 Questions: 1. out of box I am mining at 420mh/s at intensity 6. Is that good? It looks like this card can overall do about 500 out of box but my friend has told me he gets about 450 out of it.
What exactly is thread concurrency? What are some important arguments to put into the batch file when setting one up for cgminer?
Is it safe to overclock? If there is a way to overclock and stay at mid 70's for the temp, fans running at 100%, is it dangerous to do so? would the outcome be worth it?
Is there a way to overclock it and keep temps mid 70s?
Hi i have been trying to optimise my settings for the Gigabyte 7950 windforce card i have, but it doesn't seem like is run as fast as a could... So I have a few Litecoin mining rigs running, and the latest has three Radeon HD 7950 cards in it. I detailed most of the hardware in my previous post, but this time I wanted to provide some clear steps and settings for mining that get close to 600kHash/sec on a single 7950.If you look at a list of scores, for example this list, you might think hitting 600kHash is trivial. May 7, 2013 Filed under: Bitcoin and tagged with: cgminer, cgminer config file, gpu-engine, gpu-memclock, increase mhash, mhash, optimize cgminer, setup cgminer Anyone who starts out mining Bitcoins for the first time generally stays away from cgminer because it takes a little bit of over clocking knowledge if you want to get the best Mhash/s from your GPU or GPU’s.
