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!

(Dummies Guide) How to simultaneously run multiple instances of cgminer to control different GPUs whilst using BAMT.

In cgminer you cannot specify multiple values for gpu-threads. gpu-threads is a global per-instance setting, not a per-GPU setting. If you want to run 2 different values of gpu-threads, you need to run 2 instances of cgminer.
This guide will help you if, for example; you have a rig in which one or more of your cards run better with gpu-threads set to 1 and your other cards run better with gpu-threads set to 2 (or 3 or 4)
So I'm going to assume here that you're running a rig with 4 cards and you're already set up and mining.
I'm also going to assume that you know how to use nano. So let's say your cgminer.conf has the line "gpu-threads" : "2", Unfortunately your 4th card isn't giving you the hash-rate you're expecting from it or worse, you're getting hardware errors which lead to rejected shares.
(to see if you're getting hardware errors in BAMT, you need to be able to see what cgminer is actually displaying. To do this simply SSH to your rig, log in and type "screen -r". I won't go too into this to much but where it says HW: you don't want so see anything there, if you're seeing anything other than 0 then you have problems with your config. Now to detach from this screen you need to press "ctrl+A+D" this is very important, do not press q!)
Anyway, you know that the 4th card wants to run with "gpu-threads" : "1", but you can't do "gpu-threads" : "2,2,2,1", this will not work!
So to get 2 cgminers running, follow these steps:
  1. SSH to your rig, be logged in, and a super user. You should be seeing this: [email protected]:/home/user#
  2. Type "nano /etc/bamt/cgminer.conf" Add the line: "device" : "0-2", This is saying that this instance of cgminer will be controlling GPUs 0, 1 & 2. Save and exit (ctrl+x)
  3. Type "nano" This will create a new script that you will run later to boot up your 2nd cgminer. Now type "chmod u+x" and hit enter.
  4. Add your info. below is mine but you want to replace with the settings for your 4th card (gpu 3): (where it says "device 3" this is saying that this instance of cgminer will only run gpu 3 (4th card) and "remove-disabled" makes it so it won't display the other cards)
    export DISPLAY=:0 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export CGMINER_BIN=/opt/miners/cgminecgminer $CGMINER_BIN --scrypt \ -o -u username -p password \ -o backupminingpoolserver:3333 -u username -p password \ -I 20 \ -w 512 \ --gpu-threads 1 \ --thread-concurrency 32765 \ --gpu-engine 990 \ --gpu-memclock 1500 \ --gpu-powertune 11 \ --gpu-vddc 1.025 \ --device 3 \ --remove-disabled \ --temp-cutoff 99 \ --temp-overheat 95 \ --temp-target 85 \ --auto-fan \ --gpu-fan 50-85 
    Note: Make sure there are no random spaces at the end of any of these lines and also make sure that the I for intensity is upper case.
    Now save and exit the script by hitting ctrl+x etc.
  5. type "screen -ls" and hit enter, you should see something similar to this:
    There are screens on: 4366.pts-1.bamt-miner (12/30/2013 08:00:56 PM) (Detached) 1 Sockets in /varun/screen/S-root. 
    So this is saying that there is currently only 1 screen running and BAMT is using it to run cgminer inside.
  6. Type "screen" and hit enter, it will come up with a load of text about screen, just ignore that and hit enter again. Now you are inside your new 2nd screen.
  7. Now type ./ You should now see cgminer boot up and start mining with just gpu 3. To detach from this screen you need to hit ctrl+a+d.
And that's it, there should now be 2 screens running.
To check the other screen type "screen -ls" and hit enter, you should now see both screens running. Something like this:
There are screens on: 6349.cgminer (12/30/2013 08:08:35 PM) (Detached) 4366.pts-1.bamt-miner (12/30/2013 08:00:56 PM) (Detached) 2 Sockets in /varun/screen/S-root. 
To look at one screen type "screen -r 6349", to look at the other type "screen -r 4366" (remember to detach from screens using ctrl+a+d)
You should still be able to see info for the first 3 cards on BAMT's web UI and in fact I can still see the temp and load for my 4th card.
Please feel free to leave feedback, or let me know if I've missed anything.
I hope you found this guide useful and if you did please consider a small BTC donation :)

[IDEA] CGMiner Best Settings System

CGMiner GPU settings are not intuitive to properly allow a user to get the best hash out of their particular card. Each individual GPU has a 'best setting' that often does not perfectly translate to another card of the same model. There is a huge demand for assistance in determining the best settings for each card.
I think there's enough evidence to suggest that simply maxing out a GPU's overclock settings is not necessarily the best way to get the highest performance.
Graham Forest discovered this a few years ago and built a very good histogram of the results. He wrote a simple program to test a huge range of possibilities and find the area of best results. His program cgminer2rrd includes much of the capability required
The cgminer 3.7.2 SCRYPT-README notes this. Spinx on the bitcoin forum also makes a note of this ratio.
In my own case, I found several ratios between gpu-engine and gpu-memclock that resulted in best performance. Here's a data table I made. Altering this ratio by even a small amount drastically affected hash rate.
I found the same thing with intensity. -I 14 resulted in significantly lower performance than -I 13.
I propose a software solution that will test a range of value combinations and create a visual representation of the results.
Record/Display test values
Test a range of GPU/Memory value ratios
Test a range of Intensity settings
Test Duration
NOTES I'm just a guy who noticed a problem and found a good starting place for a solution. I'm not a programmer, but am experienced in working with developers to create software solutions.
TL;DR Make a program that will auto test a range of cgminer configurations.

AMD Malta 7990 Performance & temp issues

Hello here
So, as a Lite/Bitcoin believer and computer geek without any savings, last week I ordered a Radeon HD7990 to get in that train and go to the moon.
I mounted that beast in a Cooler master case + 850W power supply gold standard, and run cgminer with those settings :
setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer --scrypt -o stratum+tcp:// -u x -p x --intensity 13 --shaders 2048 --thread-concurrency 8192 -g 2 -w 256
After 2 days of trial and errors
I achieve a hashrate of 1100 Kh/s
GPU0 : 400 Kh/s average / temp 79C GPU1 : 700 Kh/s / temp 85 to 90C
GPU1 temp is quite high but with better fans it sounds ok
My issue is that GPU0 is stuck at 501 MHz and voltage seems to play between 0,950V and 1,117V while GPU1 voltage is standing at 1,200V
But the main issue is that GPU0 VRM temp rises to 130C, while it stays at a steady 80C on GPU1
I tried to change the voltage with trixx or other software but it s impossible...
Running Catalyst 13.9 / AMD SDK 2.9
I m fearing fire in my case with VRM running at 120 / 130C, or at least the card blowing
Any advices / config ?
Thank you

Help with a Gigabyte GV-R928XOC-3GD REV2

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:
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:// -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. :(

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://" 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!

AMD 7950 only at 15 Kh/s with any setting

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.

I'm totally new to mining and crypto-currency. Help me mine my first dogecoin!

I had known that Bitcoin exists since a while. But read it up on Wikipedia for the first time today. I said hey, I want to make money too. Did some quick research and decided upon Dogecoin. I have set up an account on and set up cgminer 3.7.2 on my Hackintosh. I've got no specific hardware, just a 5450 HD. I have a few questions:

iwtwe's Total Noob Starting Guide. much noob..such help...very

NOTE for seasoned miners, if I have made a mistake or if there is an easier way of configuring the miners or if I left something out, please do not hesitate to contact me about it so that I can edit this post accordingly. Let's help new people out so that the community will continue to grow! many
Hey you. Yes you with the eyes. Are you new to the world of crypto coin mining? Have no idea what a dogecoin is? Want to start mining dogecoins today and just can't seem to figure it out or get it to work?
Well have I got much help for you! About a week ago, I finally started mining after two painful days of trying to get it to work. Basically, I was a total noob and didn't really understand anything about mining in general. Because of the joy mining has brought me so far I am writing this guide to hopefully help out new members or other total noobs.
It's safe to say I've been bitten by the dogecoin bug. I started out with a measly 50 khash/sec and made approximately 10 coins in 12 hours. * My reaction when I finally got my miner to work * Reaction cont.
Now I'm up to 500 khash/sec after figuring out all the 'nuts and bolts' of mining. wow...such optimization...many hash
I'll break this guide down into three categories: Detailed Info, CGMiner Config for AMD Cards, and lastly, CUDAMiner for Nvidia cards.
Detailed Info very
A dogecoin is a type of crypto currency that is traded against bitcoins in a crypto currency marketplace.
You can earn dogecoins by contributing hashes (computing power) to a mining pool to help find a block.
There are a certain amount of dogecoins that will be released. These coins are released in the form of a block ranging in quantity of 1-1,000,000 doge coins. It is worth noting that the total quantity of coins per block will soon be halved to just 500,000.
Things you will need to mine: * dogecoin wallet * computer with a GPU * an account with a mining pool * a worker for the mining pool * mining software
1) [](Download the doge coin wallet and install it)
2) Turn off your computer's anti-virus software and allow the dogecoin wallet through your fire wall. *VERY IMPORTANT
3) Run the dogecoin wallet and let it sync with the network. It is important to note that this can take a short amount of time or even up to 12 hours to complete. Just be patient. Use that time to research mining more.

Once your wallet has synced with the network, it is time to sign up with a mining pool. Think of a mining pool as a virtual supercomputer that is made up of many smaller computers connected together. This pool or 'super computer' allows for greater processing power. More processing power = greater chance of the pool finding a block.

Finding a pool
"Dear shibes!
Be careful when running Java and/or entering the usepass on sites. There are phishing sites out there that imitate other pools to steal your data.
When accessing a mining pool, DO NOT follow any redirects, always access the site directly and check the URL. For extra security, make sure you're using https://
Don't run Java!" <--- not my words, but very good warning to take into consideration
1) Perform a quick google search or use the links in the side bar to find a pool!
2) For this example I will be using (I in no way, shape, or form endorse this particular pool. It was the first one I clicked. Feel free to use any pool you want, as the sites are all the same.)
3) You're going to want to click "Sign Up" in the menu on the left of the page. After clicking, sign up for an account.
4) After signing up for an account, log into your account. (For the sake of my example my mining pool site username will be "Shibe")
5) Now we will create a pool worker. Click "My Workers" in the menu on the left side of the page.
6) Choose a worker name and worker password and click submit. *NOTE THE WORKER NAME IS NOT THE SAME AS YOUR ACCOUNT USERNAME
7) For the sake of the example my workers name is "worker1" and the password is "x". *Note capitalization matters so don't forget it.
Now we will download a mining software and configure it to mine.
Before we do that I want to clarify what the info we will be using to configure our miner is.
1) Click "Getting Started"
In my example pool under getting started you will see this in "Step 3":
  1. Configure your miner.
    Settings for Stratum (recommended): STRATUM: stratum+tcp:// PORT: 3336 Username: Weblogin.Worker Password: Worker Password
If you use a command-line miner, type:
./cgminer --scrypt -o stratum+tcp:// -u Weblogin.Worker -p Worker password
The above explained:
Final Step Regarding Mining Pools
We need to add our payment address to our mining pool account so that we can receive the dogecoins we help mine.
1) Click "Edit Account" on the menu on the left side of the page.
2) Scroll down until you see "PAYMENT ADDRESS".
3) Minimize the webpage and go to your doge coin wallet.
4) In your dogecoin wallet click the "Much Receive" tab.
5) You will see the Label "Default" with an "Address" composed of a long random string of letters and numbers.
6) Right-click that string of random numbers and letters and select "copy address".
7) Maximize the pools webpage again and paste that address into "PAYMENT ADDRESS".
8) Enter you pin and click "Update Account".
WE'RE NOW READY TO DOWNLOAD A MINER such hooray....many celebrate
*Note AMD cards are much better for mining than Nvidia. It's just the way it is!
We will be using cgminer to mine dogecoins with our AMD cards.
While there are newer versions of cgminer avaliable you're going to want to download cgminer version 3.7.2 because any higher versions do not support GPU mining.
1) Make sure your AMD drivers are up to date.
2) This version of cgminer is now only available on gitub at this url. The option to download the zip file in on the bottom left right side column.
3) After downloading the file, extract its contents to a folder on your desktop.
4) Before we do that go to Control Panel Folder Options View select "Show hidden files, folders, and drives" and click apply.
BEFORE YOU TRY THE BELOW, RUN THE APPLICATION AND INPUT THE SERVER URL:PORT (stratum+tcp:// "enter" USERNAME (Shibe.worker1) "enter" and PASSWORD (x) "enter".
*If the application runs without giving you errors hit the [S] and select "create config file" and hit enter.
5) If that didn't work, we will make a .conf file that allows cgminer to run correctly.
6) Now go to the folder you extracted cgminer into.
7) Right-click anywhere in the folder and select "New" Text document.
8) Right-click the new text document you just created and select "Edit".
9) Copy and paste the following into that new text document leaving no space at the top and enter the appropriate pool information accordingly. Noticed I used my STRATUM info from my example.
{ "pools" : [ { "url" : "stratum+tcp://", "user" : "Shibe.worker1", "pass" : "x" } ] , "intensity" : "10", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "0", "thread-concurrency" : "0", "shaders" : "0", "gpu-engine" : "0-0", "gpu-fan" : "0-0", "gpu-memclock" : "0", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "temp-cutoff" : "95", "temp-overheat" : "0", "temp-target" : "0", "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "0", "scan-time" : "30", "scrypt" : true,
{ "pools" : [ { "url" : "stratum+tcp://", "user" : "Shibe.worker1", "pass" : "x" } ] , "intensity" : "10,10", "vectors" : "1,1", "worksize" : "256,256", "kernel" : "scrypt,scrypt", "lookup-gap" : "0,0", "thread-concurrency" : "0,0", "shaders" : "0,0", "gpu-engine" : "0-0,0-0", "gpu-fan" : "0-0,0-0", "gpu-memclock" : "0,0", "gpu-memdiff" : "0,0", "gpu-powertune" : "0,0", "gpu-vddc" : "0.000,0.000", "temp-cutoff" : "95,95", "temp-overheat" : "0,0", "temp-target" : "0,0", "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "0", "scan-time" : "30", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/uslocal/bin" }
10) Click save-as Save as type, "All files" and rename the document to: cgminer.conf
11) Click save and run program.
12) If it still doesn't work try changing the intensity to a lower number or changing the workspace value to 64.
Everything should work now. If I have made any errors or if there are easier ways of doing this please let me know so that I can edit this. This is just what worked for me.
Before we do anything, go to Control Panel Folder Options View select "Show hidden files, folders, and drives" and click apply.
We will be using Cudaminer version 2013-07-13!hVREmSKA!VaGCdh3Ykfp-e8IOTFWaEXJGMa1JNVqPcdxawkCPRSE
1) Download Cudaminer version 2013-07-13 from that link and extract the contents to a folder on the desktop.
2) Open that folder and look for the Application.
3) When you've found the location of the Application it's-self you're going to right-click anywhere in the folder and select "New" Text document.
8) Right-click the new text document you just created and select "Edit".
9) Copy and paste this to the top line of the blank text document leaving no space in front and input the appropriate url, username and password from whatever pool you use. (I will be using my example pool info stated earlier in this post):
cudaminer.exe -o stratum+tcp:// -u Shibe.worker1 -p x
10) Click save-as Save as type, "All files" and rename the document to: Launch.bat
11) Click save.
12) Double click the Launch.bat file you just created to run the program.
13) Wait for the program to auto-tune your settings and then it will start mining automatically.
Everything should work now. If I have made any errors or if there are easier ways of doing this please let me know so that I can edit this. This is just what worked for me.

[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:
None of those will have any affect on how fast you mine. The settings that we'll be focusing on are:
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:
kernel save_binaries yes enable_graceful_shutdown no long_polling yes platform 0 device 0 #mine bitcoin mine litecoin #mine solidcoin 
This will make it mine litecoin on your first graphics card and reference litecoin.conf, which for me looks like
host port 8080 user poolusername.1 pass anything protocol litecoin worksize 256 vectors 1 aggression 18 threads_per_gpu 1 sharethreads 32 lookup_gap 2 gpu_thread_concurrency 15380 
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:
{ "pools" : [ { "url" : "XXX", "user" : "XXX", "pass" : "XXX" } ], "auto-fan" : true, "gpu-engine" : "920", "gpu-fan" : "0-100", "gpu-memclock" : "1375", "gpu-powertune" : "20", "gpu-vddc" : "1.219", "temp-cutoff" : "85", "temp-overheat" : "80", "temp-target" : "75", "temp-hysteresis" : "3", "kernel" : "scrypt", "gputhreads" : "1", "thread_concurrency": "8192", "worksize": "256", "intensity" : "dynamic", "vectors" : "1" } 
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 jk this isn't a car insurance add. For your better understanding, become familiar with these terms:
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.
I hope all things go smoothly for you and that you've learned a lot! Please consider donating LTC to

How to get more than 322kh/s with a 5870?

I have a friend running windows and cgminer and he gets almost 400kh/s with a 5870 without configuring anything...
Under Linux with Ubuntu, I really cannot get past 322kh/s.
I know there were a lot of 5870s back in the gpu days of bitcoin and I guess a lot of you mine with these now. No?
So how do you guys do it, I wonder? What hashrate do you get with your 5870s under Linux? I have 8 of them and I'd really like to push my scrypt mining to the max.
Excerpt of my cgminer configuration: --gpu-engine 710 --gpu-memclock 1250 --intensity 18 --thread-concurrency 7168

Cannot get over 450kH/s with my 7970..please help

I'm able to hit 730Mh/s bitcoin mining with my Asus Matrix Platinum [email protected] 1250mhz core/1725mhz memory...but for some reason i cannot get over 450kH/s reliably litecoin mining.
Using the configs they use in
Using either CGMiner or GUIMiner - none of the 7970 configs are very good for me
The highest stable memory i can get is using 0.57 rule, ive tried a core speed 984mhz..still doesnt help too much. Anyone have other configs i can try? I'm using as my pool.
EDIT: Also using the newest 13.3 Beta drivers...i wonder if this has something to do with it..or maybe i should change pools..
These are the flags im using:
cgminer --scrypt -u jerrolds.worker1 -p x -o stratum+tcp:// --shaders 2048 --worksize 256 --intensity 13 --thread-concurrency 8192

cgminer High CPU Usage in Linux?

I started out with a test Win7 install and switched to Ubuntu, but CPU usage is pegged in Linux and was nothing in Windows. I went with a cheap CPU (Ivy Bridge Celeron) not expecting to need it for much.
I looked around saw warnings about intensity, but. That was mostly for bitcoin mining.
Am I missing a cgminer flag or have a misconfiguration?

5830 questions

I've seen reports of 5830s pulling nearly 300kh/s. I can't get mine over ~150. Using cgminer, if I set the intensity over 11 I start racking up hardware errors left and right. I've adjusted clocks in both directions and the hardware error rate seems to be entirely based on intensity. Is it possible I've just burnt it out after a year plus of 24/7 bitcoin mining?
Ordered a 6950 yesterday and hope to run both.

cgminer 3.7.2 overheating my 5770. Do --temp-target or --temp-cutoff actually do anything?

I have an old HD 5770 which I thought I could pop some coins out of but I cannot get the mining software set up. I am running cgminer 3.7.2, and with default settings fresh from the install I get ~27kH/s but that seems low, others report ~130-190 with 5770's. When I try others suggested settings (seems mainly higher intensities) I get a boost to my hash rate but the card gets very hot and shoots up to over 90C in a minute or two and the safeties don't seem to kick in.
--auto-gpu with a temperature target seems like it should be ideal, but I cannot get it to hold any target temperatures.
Does --temp-cutoff do anything? I usually monitor the temperature with speedfan and shut it down when it hits mid 90's, cgminer does not seem to care about high temperature. I thought it had a default setting of 95 for the cutoff, am I mistaken?
Are there alternative programs for AMD mining with a pool? I cannot get guiminer to start, and most other programs only have documentation for bitcoin or litecoin.
I should add, I am passing these setting with the mine.bat file, I tried messing with the .conf file but it didn't seem to change any temperature settings either.
edit: Thanks for the help so far. I think my old .conf file might have been stopping my new temperature settings from being taken up. I got a "REST" status in the kH/s area when I hit the cutoff, but cgminer did not seem to pick up the trail again after the temperature dropped back to normal, it said it was reactivating but I just got that "stratum from pool detected new block message" over and over again. I really like cudaminer for the "yay!"s and such. I don't even know when I hash something in cgminer.

Tuning help requested!

Hello fellow Shibes!
I've been mining on my dual GPU rig and thinking I was doing quite well until someone noticed that my hashrate was significantly lower than expected and suggested I take a look at my settings. I couldn't see anything wrong, but I'm always looking for suggestions to improve the hashrate in the box.
I'm running two HD5850 Radeons on Debian and am getting the below hashrate reported by cgminer v. 3.1.1:
-------------------------------------------------------------------------------- [P]ool management [G]PU management [S]ettings [D]isplay options [Q]uit GPU 0: 15.0C | OFF / 0.000h/s | A: 0 R: 0 HW:0 U:0.00/m I: 0 GPU 1: 74.0C 4109RPM | 131.0K/129.7Kh/s | A:10616 R:75 HW:0 U:1.76/m I:11 GPU 2: 74.0C 1339RPM | 131.4K/129.7Kh/s | A:10712 R:78 HW:0 U:1.77/m I:11 -------------------------------------------------------------------------------- 
GPU1 and GPU2 are the Radeon cards, GPU0 is the onboard card being used for monitoring and admin of the server.
My intensity for both cards is set to 11, if I set it to 12, I start getting hardware (HW) errors, if set to 10, then the hashrate is effectively halved.
I start off cgminer with the following parameters: cgminer --scrypt --auto-gpu --auto-fan -d 1 -d 2
I will admit that I'm not too familiar with cgminer, I bought this rig from a friend after GPU mining went unprofitable for Bitcoin, but it was just in time to start mining the sweet sweet Doge. :)
If needed, I can post my config (less my pool data) or I can obtain whatever info you may need to help me.
Thank you in advance!

Getting only around 130Kh/s with my HD7870.

Hey there helpful shibes,
I have a problem with my mining setup.
Looking at this chart for litecoin mining: 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
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.

CGMiner corrupting video drivers?

Hey Guys,
I'm at my wits end here. I'm trying to get my GPU mining btc so I can warm up my bedroom now that temps are falling. Seems like a cool way to keep the room cozy.
Motherboard: ASUS F2A55-M LE FM2 AMD A55 (Hudson D2) HDMI Micro ATX AMD Motherboard with UEFI BIOS
GPU: XFX Core Edition FX-787A-CNFC Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0 x16
Memory: G.SKILL Sniper Gaming Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
SSD: SAMSUNG 840 Series MZ-7TD120BW 2.5" 120GB SATA III Internal Solid State Drive (SSD)
Power Supply: CORSAIR HX series HX650 650W ATX12V v2.2 / EPS12V 2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply
So here's the chain of events:
Fresh install of Windows from the ground up. All windows updates applied.
Installed chipset drivers for motherboard (AMD onboard drivers by and large).
Installed GPU drivers (Catalyst 12.8) plus AMD SDK.
Started up CGMiner 3.4.2 (stable on other builds). Immediate artifacts.
Quit CGMiner, artifacts remain.
Reboot system, entire screen is all blue with vertical white lines, system reboots in infinite loop.
Have to start in safe mode, use AMD driver cleaner to remove all AMD drivers but can't uninstall Catalyst Control Center b/c safe mode doesn't allow msi installs (??? really?).
Restart computer, re-install video card using Catalyst 12.8, try mining, get immediate artifacts.
Tried this three or four times, using Catalyst 12.8 and Catalyst 13.1, alternating PCIe slots with video card. No artifacts until I try to mine with CGMiner (with and without GPU autotune, with and without Memory autotune, alternate using "d" or "9" for intensity, makes no difference).
Used driver sweeper to remove all AMD drivers thinking that maybe the AMD cleaner is incompletely removing drivers (bad idea with AMD supported mobo).
Restart, normal mode BSODs with BUGCODE_USB_DRIVER error, safe mode is fine. I assume video card is dead and remove video card.
Notice motherboard drivers are missing. Reinstall motherboard drivers. Reinstall video card.
Install 13.9 Catalyst.
No issues with stress tests on GPU using video games or freeware stress tests, so I assume GPU is good, plus it is an RMA replacement for a known bad video card, plus issue happened on another known good video card, so I'm pretty confident ruling out an HW issue with the video card. Memtest86+ over 24 hours revealed no issues with RAM.
Anyone else have problems with CGMiner actively corrupting video card drivers? I'm assuming that's the issue because my system is stable until I try mining, and then I have to go through all this hoopla to get my system stable again. I'm at my wits end, and will probably give up on trying to heat my room with bitcoin unless someone has any idea what the hell is going on... Suggestions?
Edit: So it appears to be the video card after all. Evidently the first video card I tried really was a driver issue. When I replaced the first one, I replaced it with a bad video card. Fucking ugh.

Some questions I have about mining

I intend to mine a bit on my gaming rig (my only computer, and I cant afford anything else). Not serious but maybe squeeze 10 bucks a week or something.
Q1: What config do I use?
I have a Sapphire vapor X 7970 Ghz model 11197-12-40G and I get about 400kh. I read that is way too little for my GPU, i use thing config.
set GPU_MAX_ALLOC_PERCENT=100 set GPU_USE_SYNC_OBJECTS=1 cgminer --scrypt -I 13 -g 2 -w 256 --thread-concurrency 8192 -o stratum+tcp:// -u coldblade2000.coldblade2000 -p die0600g del *.bin 
Q2: How do I make sure I get a good enough amount of bitcoins without killing my poor GPU?
I really cant afford another GPU, and this is my main and only computer. If it breaks, I'm SOL and left without a computer for months. How do I make sure I never kill my GPU?
Q3: What intensity/settings do I use to run thought the night safely?
Since I can use the night as time to mine without interrupting my computer usage, I thought I might as well, but I think my current settings are way too stressing for that. What do I change?
Q4: Is my pool ok?
I have been using and I just got my first payout, 288 doge. Not as much as I hoped but I don't see any other choice. Should I change pool? To which? I tried p2p pools but I found their interface annoying.
Q5: Is it worth it?
I don't intend to do this full time, or to become rich. I might just use 10 bucks a week or months, and keep the rest for when (if) doge goes up in value by a lot. Is this really worth the hassle, electricity bill and danger?

Looking for good dynamic GPU miner

I currently mine on my 6950 using CGminer, and I get about 430 KH/s at intensity 18. This causes my computer to become close to unusable, meaning that I switch to mining bitcoins when I am on my computer using BFGminer. Is there a miner for litecoin that will have a small hash rate drop in dynamic mode, as opposed to the ~18KH/s that CGminer gets? Thanks in advance.
