All very good insights, thanks!
I installed the chipset drivers last night and that bumped speeds up to 700. So that was good. However, playing around with clock speeds indeed sometimes increased hash rates but sometimes actually didn't do anything at all. Seems to be a tricky balancing act. Leaving gpu clocks at 1070 but increasing ram clocks to 1700 (from 1600) seemed to have made quite a difference. I'm going to have to try down-clocking it to 1500 but that does feel quite weird heh!

Also, I've done that while connecting to a switching pool, it probably would make sense solo-mining when tweaking as you'd want to rule out pool-connection effects...

Lastly, I just heard I should set the priority to above normal... still need to try that out tonight.

Btw I do use the newer, NON-v2 version.

Hey mate,

I have the exact same cards. I have between 740 kh/s (4 cards on one MB) and 750 kh/s (single card on motherboard) with those settings:

Hope it helps
