1  Other / CPU/GPU Bitcoin mining hardware / Advice on building Litecoin mining rig on: April 11, 2013, 04:19:39 AM
Ok, I already have the RAM (8GB Mushkin) and a 650W Antec TruePower New PSU and a HDD.

I need to purchase a mobo, case, GPUs (2 or 3) and a CPU. If I can power 3x 7950's on the 650W Antec I already have then I'll buy 3 GPUs.

So far this is what I've picked, if you can advice better/cheaper then let me know:

Hi,

I want to mine Litecoins with my 6850 AMD GPU. I have the AMD SDK v2.8 installed for Windows and Catalyst 13.2beta5.

I have downloaded guiminer-scrypt_win32_binaries_v0.03 and registered at Coinotron. I also opened an account at btc-e to get a wallet address which I entered into the LTC payout field at Coinotron. I downloaded litecoin-0.6.3c-win32 and it is currently synchronising with the network. I didn't change any settings in litecoin-0.6.3c.

My problem is when I use guiminer-scrypt, I get the following errors after entering the account details I made at Coinotron:

Code:

Why am I getting this error? I must be doing something wrong?

Thanks!
