Quick Guide For Setting Up Cgminer For Litecoin

Quick easy guide on setting up a litecoin miner on the Coinotron pool:

1. Download the Litecoin wallet from http://www.litecoin.org/ and let that update. You don't really need it much for this but it's good to have.
2. Download cgminer 3.1 (it's what I use because 3.7.* doesn't work with GPU mining)
3. Register an account with coinotron
4. Login and create a worker
5. Setup the cgminer (Took it from this guide):

You’ll have to determine the optimum settings.

-I

Intensity, this you can set anywhere from 0 to 18 where at 18 your computer becomes unusable and might even freeze. For me the optimum setting is 12 when I’m at my computer and -16 when I’m not working on my computer. You’ll have to see what works best for you. The difference in hashrate is quite big, at 10 I only get 80Kh/s while at 16 I reach nearly 250Kh/s

--thread-concurrency

You can try any of the thread concurrencies within these ranges but it has to be a multiple of 64. Make sure you use the concurrency that fits your card model.

57xx cards: 2368-4096 (3200 is common)
58xx cards: 4096-8192 (5600, 7168, and 8000 are common)
5970 card: 4096-8192 (5632 or 8000 are common)

67xx cards: 2368-4096 (3200 is common)
68xx cards: 3008-6720 (4800 is common)
69xx cards: 4096-8192 (5600, 7168, and 8000 are common)
6990 card: 4096-8192 (5632 or 8000 are common)

7xxx cards 64 * bus_width_of_card_in_bits. So, for a 7950, that would be 64 * 384 = 24576; ideal values are 21712 or 24000. Find your bus width here: Radeon HD 7000 Series - Wikipedia, the free encyclopedia

--temp-cutoff

You can set a maximum temperature if you run into problems, the default is 95 which is ok for most cards.

I prefer to run it from cmd so I can see any error might it occur. Replace -u and -p with your own username and password.

6. Start your miner: For pooled mining you have to use: c:\cgminer-2.11.3-win32\cgminer --scrypt -ohttp://coinotron.com:3334 -u rapid86.1 -p 1 --thread-concurrency 8192 -I 10 -g 1 -w 256

Make sure you change the info in this to yours so you don't mine on my account!
