Need help w/ LTC on CGMiner

[juggalodarkclow]

I know there's a CGMiner thread but I need some help from those who mine LTC on CGMiner. I've been driving myself nuts trying to get CGMiner 2.7.5 to mine LTC with no luck, I made a .bat file with settings other users who have the same cards as me use and my pc will just lock up. I need a .bat file that will work.

Specs:
Win7 x64
2 Sapphire Radeon 5830's Xtreme
CGMiner 2.7.5

Thanks in advance!!

What I've seem with my test and cgminer is that the best config is only to set shaders, so start setting basic parameters , --scrypt --shader xxx (the # that you gpu have).

Thes best config for me is to force worksize to 256 and g to 1 (2 by default)

Dont force others, if you set lookup-gap or thread-concurrency mannually won't leave cgminer to make it auto (depending of your gpu shaders).

So for my 6770 with 800 shaders the line included in .bat looks like this:

Code:

cgminer --scrypt --shaders 800 --worksize 256  -o http://.pool.pool:9332 -u myuser -p mypass --auto-fan --gpu-fan 20-100 --temp-target 70 --intensity 16 -g 1

what are you getting on you're 6770 with that?

i'm getting 215 kh/s on my mine

[vitruvio]

Only 195 Kh/s, and i'ts overclocked to 900Mhz, I can't do more, even at 910Mhz it hangs.

Intensity looks too high - try 9.

i got 215 kh/s on both gpus with

cgminer --scrypt --shaders 1536 -o http://.pool.pool:9332 -u myuser -p mypass --auto-fan --intensity 17 -g 1
