So I have two 4830's in crossfire, each are overclocked to 575/685 core and 900/965 memory.
Here's my system specs.
Processor: Phenom II 720 be OC to 3.2 ghz
MotherBoard: Asrock A780GXE
PowerSupply: Coolermaster real power pro 750W
Memory: 4GB DDR2 1066 mhz
VideoCards: two 4830's in crossfire (one is sapphire, one is powercolor, does that make a difference?)
I got this FPS in crysis bench mark test. All settings on high, 1600 by 1200 resolution (max settings my monitor and PC can do because of directx9)
Min fps 19
Average fps 29
Max fps 38
and when I took the second card out I got this FPS.
Min fps 15
Average fps 31
Max fps 40
And I have the crossfire bridge connected (But it was on the second crossfire connector, the one furthest away from the back of the PC. does that matter?)
Crysis is a bad game to benchmark. It doesnt like crossfire, although it likse 4890 crossfire.. its a strange game..
With my old 4870's crysis pretty much ignored the second card, its not unheard of. You may also be a bit cpu bound with that setup as crysis likes raw power being that it was coded in the future where all comptuers have 16cores at 10Ghz and brought back in time forever baffling everyone why it even had "ultra high" settings 2 years ago...
Wow I never had catalyst AI on, could that be the problem?
And should I set it to standard or advanced?
By the way, just ran 3dmark06 and I saw significant fps loss, I used to never drop below 30 with second card while doing the first video card test, and I was in the constant 20's this time without the second card.
3dmark06 score is 12.9k and with second card it was a little above 16k.
Yeah it looks normal. The minimum are REALLY hard to change in crysis so dont expect miracles there. Average get a nice bump, which is well in line with your system. Shoudl tear up every other game out there
