how many xfire bridges o.O?

[AMG]

right okay stright to the point

I have a intel X48 mobo on 701 BIOS, and two sapphire HD4890 with 1 crossfirebridge

now i can see "crossfire enable" on the CCC but 3DMARK is giving scores like 17k and stuff so my second card can't be working what gives?

they both have power to em. and my powersupply is more than capable

so should I add another bridge or is it mobo BIOS I already have updated the chipset drivers

specs are in sig

and I forgot the powersupply is a ABS/TAGAN 1100watt piperrock

When I had crossfired 4870s it made no difference whether I used 1 or 2 connectors.

The only advantage that I could see with having 2 is that it looked neater.

I think that they do make a difference, though I think it's mainly at high res that it's apparent.

yeah I ve tested the "two theroy" makes no differences and 3DMARK06 is only using one card, but CCC can see two and both are active and says crossfire is enabled and stuff, so it may be my rampage formular needing a BIOS update or something.

already done my chipset drivers, than upon shuting down I got a BSOD o.O

Only 1 connector is required to Crossfire 2 cards



people use 2 because it looks Dogs ********
