The thread topic pretty much says it all. I just ran a crysis benchmark first with crossfire enabled, then with crossfire disabled, each benchmark was within 1 fps of each other (Around 24fps). I've been fooling around with my settings since I got the cards two weeks ago and I just dont feel I'm getting the performance out of them that I should. I know it was previously due to my fault, I didnt have the bios settings correct so the cards weren't running in 16x pcie 2 mode. I corrected that problem and boosted the power to each of the slots (I set it for 175 watt limit). GPUZ Shows both cards, when I enable crossfire GPUZ recognizes it and says its active. I've run 3dmark Vantage but I seem to get alot of artifacts and other errors while its running so I dont think I can trust the numbers provided. My specs are below, nothing is overclocked any advice is welcome. I have done the fan override for the ATI cards. I keep the fans at 30% normally 40% if doing alot of mult-tasking (I run 3 screens), and 60% when crossfire gaming. I think my bios settings are now optimal for crossfire but if anyone might know the exact PCI express settings for my motherboard that would be great.
On a side note, it may just be crysis. Everything else i have run has run wonderfully. But Crysis is the only recent game I have, other than that its Quake 4, Doom 3, X3: Reunion. Haven't been into PC gaming in awhile since Xbox 360 and PS3 had somewhat caught up to what PC gaming was doing for awhile (Call of Duty 4 on the 360 or PS3 is great but all I can think about is how much like the original counter strike this is...and i was playing that in 01). I'd say computers have definitely lept ahead again so I'm slowly switching back to PC gaming (Now that I think about it I accidently damaged my old computer within a month of them announcing Starcraft 2....and that led to me building my current setup)....Only problem is all the good games I seem to have already played on Xbox so have no reason to buy on PC (Bioshock, Devil May Cry 4, Lost Planet, Call of Duty 4, Oblivion, The Orange Box, Gears of War).
