Bitcoin today is what the internet was in 1998.

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.

I just found that setting the memory clock to 300 Mhz for Bitcoins can save you some temperature and Watts. Put if you are mining Litecoins, set memory to 1200 or more.

For 5870 (tested here):

300 Mhz   -> 110 Khash/s
1200 Mhs -> 350 Hhash/s
