Also what -askrate interval do you have?<br/><br/>I did get two cards working (had to use the crossfirex cable and enable crossfirex). <br/><br/>The thing that baffles me is how to get the same performance out of two cards together as I got out of two cards seperately. It seems if i set the frames very low like -frames=2 I can get one card to do about 97% gpu capacity. The other card, however drops to 60-80%. When I make the frames high like 256 it does ok but any other program on my machine seems to have a higher priority and will make poclbm.exe run slow. <br/><br/>Currently the best compromise I found was <br/>--frames=25 --rate=3 --worksize=256 --device=1 --askrate=30 <br/><br/>On a single core processor machine this produces about 90% on each card average but has wild swings.<br/><br/>For a while I thought the issue was my MB or CPU not feeding the data fast enough but I tried the cards in my gaming machine with a quad core and dual x16PCIe slots and it still was about the same.<br/><br/>Any ideas?</div> text/html
