4850x2 Crossfire Problem

[Rab2140]

Hey all, yesturday i bought a 4850x2 graphics card and perfoemance is sweet but, I do not think my crossfire is working. When i disable crossfire i see no performance decrease in any application or game and the other way round. When i enable crossfire nothings seems to respond differently.

The apps i have tried is:

Crysis
3dmark06
folding at home gpu

I dunno if its drivers . i have the latest 9.4.

Thanks

can you post 3d mark score with X-fire enabled and disabled?

I just installed vist there and it seems that crossfire is working. in pixel shader test i diabled CF and got 250 fps and when it was enabled i had 500. Is it and xp driver problem?

I was worried because i have this card in a 680i MB and a pcie 1.1 slot

GPUz is reporting the slot as pcie2.0 though ;/

i have a 4850, whats your mobo, does it have 2 pcie x16 2.0 slots? i dont think it will work on pcie 1

But he has a 4850X2.
And no, two cards will not fit in one slot, if you didn't know.

Perhaps the 4850x2 just isn't scaling well, CF should see the most benefit on high resolution gaming, and maybe with AA enabled, probably highest settings too.
