It can help. For 2GB RAM you're limited to some 8196 TC.

I can't remember if that setting works on 2GB but so happen I experimented it on my 8GB (work) machine and it gets me 400Kh/s.

*
hmm... i tried changing to higher TC but get bad hashrate .... think for me the gpu are stuck at 8193 and average 720 kH/s .... sad.gif

Other way is to perma flash the bios rom using atiflash....

I thought a psu with rated 1000w can produce 800w going by the efficiency math. Assuming gold 80+ probably can give u 900-950w?

860W from the wall on 3 x 280X currently, although third card is doing 670Kh/s where as the first 2 are 720Kh/s (identical cards and settings)

Going to let it run for a bit then add 2nd PSU and more cards.

Think I screwed up one of my boards by putting the riser in the wrong way around into the 16x slot  blush.gif

4x vapor-x draws me 950W ....

What settings / voltage are you using?
*
1.050V for gpu 1,2,3
1.081V for gpu 0

initially with all 4 gpu at 1.050v im getting 850W... but gpu 0 always unstable, bumped it up to 1.081V

How about GPU / Memclock?

I'll try changing voltage down a bit further and see how it goes, every little helps. Just a pain in the ass that I can't change voltage with sgminer and need to flash the BIOS each time sad.gif

Thanks. I get an error if I try tc @ 8193

Otherwise settings are nearly the same - 3rd card still gets less Kh/s though.

Will try lowering voltages a bit more, see if can reduce usage a bit then add next PSU and GPUs smile.gif
