I am mining for Litecoins on a AMD Radeon HD 5830 graphics card (Sapphire brand) at stock clocks and an ASUS 5870 (reference model) at 1.212 V, 970 (core)/1250 (memory) clocks.
I'm currently getting ~587 kH/s combined on both cards.
worksize 256
aggression 16
threads_per_gpu 3
sharethreads 16
lookup_gap 2
gpu_thread_concurrency 6144
Are there better settings to use?
Also, TRIXX reverts settings back to stock whenever I edit them on my 5830, and AfterBurner displays all of the clocks at zero on the 5830, unmodifiable (reverts back to 0 when I change them.) Any ideas on how to fix this? I had them both overclocked a while ago. I'm using Catalyst 12.6.
