Hi Guys,
I'm running out of ideas.. I'm getting really low FPS in games but speed are good if I enable only 1 card.
I tested both card 1 by 1 for about 10 days each to make sure everything was fine.
3D Marks 11 Score with default settings:
P 7431 (Crossfire)
P 4618 (1 card)
Everything seem fine in 3dmarks.. lower then I expected but at least i know the crossfire work.
I tried latest Ati drivers 11.1 (with 11.1a hotfix & profile 10.12cap2 )
I tried earlier version 10.11 with hotfix & old profile ..
Crossfire is enabled in CCC.
Update my BIOS to the latest version.
Tried 3 different bridge for the crossfire.
I cleaned the drivers, reinstalled, tried a new Windows 7 install on a different HD & on a VHD.
Crossfire enabled in CCC.
Same results.
Crossfire All resolution at 1920x1080:
Dirt 2 - 60 fps average in the benchmark everything maxed
Mafia2 - 63 fps average in the benchmark everything maxed NO physx
Bad Company2 - 80~90 fps everything maxed
COD Black Ops - 70~90 fps everything maxed
1 card at 1920x1080:
Dirt 2 - 70 fps average in the benchmark everything maxed out
Mafia 2 - 56 fps in the benchmark everything maxed NO physx
Bad Company2 - 80~100 fps everything maxed
Cod Black Ops - 70~110fps everything maxed
My Spec:
MSI P55-GD55 (16x,4x bus lanes)
XFX 6950 2gb x2
i7 860 Intel
Antec Truepower 750W
G.Skill F3-12800 9-9-9-24 2x2gb
2x WD 500gig Black Raid 0
Everything Stock no O/C.
Something seem wrong.. but i have no idea what it is.. Unless it's the 4x lane on the second pci express screwing me up.. i don't have anymore ideas.
Please help.
thanks
Ben
