Hey guys. I just snagged up another GTX260 card from someone for cheap and wanted to check them out SLI. To my dismay it seems that I'm actually getting LESS performance out of this setup. My rig is as follows:
Intel i5-2500k@3.30Ghz
8gb DDR3 1066 memory
ASRock Extreme3 Gen3 Mobo
635W Sigma shark PSU
I went and made sure SLI was enabled in the NVCP and set both cards to same clocks with evga precision. Still can't seem to get any improvements. When I run furmark I'm only pushing 20% CPU load so I cant bring myself to believe I have a bottleneck issue. The only thing I can think of is my device manager Im now showing an unidentified graphics adapter, though I do have both 260's showing as installed with the same driver version. Btw, this isnt really a permanent install as Im sure my psu wouldnt handle these cards together well over time but Im more so curious as to why Im actually getting slightly WORSE performance with these in SLI. Any thoughts? Thanks!
PS, Not sure if it's relevant, I think I have 1 GTX-260 standard and 1 GTX-260 Superclocked edition, though I think it would be irrelevant if I set their clocks to match?
