Crossfire problem/question

[Ballz]

Mobo - Asus P7P55D Deluxe
GPU - 2 x Asus EAH6850

Ive recently update the Bios on my mobo & noticed the following in the Catalyst Control Centre :-

The cards are plugged into the x16 PCIe slots so am I missing something here? Shouldnt both card's "maximum bus setting" be x16?

I cant see any setting to ramp the PCIe setting up to x16 in the bios... is it showing x8 because its PCI Express 2? or is that me talking crap?

Cheers in advance

it must be x16 in single card mode and 2 x x8 in dual card...dont worry dual x8's are only about 2% slower than dual x16...you would never notice the difference

Yep, with 2 cards running this will drop to 8x, like Cammy5477 mentions there will be minimal performance loss.

Just a thought... I have a creative PCIe sound card in one of my slots .... could this be having a negative effect on my x8/x16?

I also have a motherboard that's only duel X8 PCI-E, It's reassuring to know.. I actually thought I'd have to buy a 16X/16X Mobo. Thanks for info.

Ignore that, it's stupid Upon finding the motherboard user guide it is indeed x8 in Crossfire & Sli.

Cheers people for the help.
