How to run Litecoin mining on Windows with a GPU with CGMiner
1) Download CGMiner 3.7.2 here:
(If that link becomes dead, please contact me and I’ll update the blog with a new reference or self hosted copy.)
It’s important that you use CGMiner version 3.7.2 as that is the last version before it stopped supporting GPU mining for LiteCoin.
2) Extract the Rar file for CgMiner anywhere on your Windows computer.
3) Setup a LiteCoin mining pool account. I have used both: give-me-coins.com and litecoinpool.org – They both worked fine and seem legit. Create an account and ensure you have at least one worker setup.
4) Setup OpenCL or CUDA for your computer’s GPU. I had already done this as part of a previous article where I setup my computer for Windows GPU processing. CUDA is specific to NVidia cards, and NVidia cards can also use OpenCL. Setting up OpenCL (or CUDA) is pretty specific to the exact GPU you are using, so I can’t give you specific instructions on those details.
5) Run CGMiner by starting CGMiner.exe. On a command line run CGMiner.exe like this:
cgminer.exe -d 0 --scrypt -o http://ltc.give-me-coins.com:3333 -u StyleMyImage.blog -p 123456 --thread-concurrency 6400 -g 1 -w 128 -I 12
- The –thread-concurrency should be a multiple of your GPU’s shader count. Mine is 640 shaders, hence my –thread-concurrency set to 6400
- The “-a scrypt” tells minerd to use the LiteCoin hashing algorithm.
- The “ltc.give-me-coins.com:3333” is the pool mining address for Give-Me-Coins.com
- The “-d 0” indicates to use the GPU device with address 0.
- The “-u StyleMyImage.blog -p 123456” are the user and password for your mining worker. You can add more workers, change names, and change passwords through your mining pool’s dashboard and portal controls.
An example for running cgminer.exe to litecoinpool.org would look like this:
cgminer.exe -d 0 --scrypt -o http://us.litecoinpool.org:3333 -u Mandelhoff.blog -p 123456 --thread-concurrency 6400 -g 1 -w 128 -I 12
That’s everything for mining Litecoin with your GPU on Windows using CGMiner. Enjoy!
