Crossfire & PCI-E speed/slot question

Hello all,

I just re-imaged my desktop (IBuyPower) and noticed after post it lists the PCI-E slot as 1x 5gbps. I'm running two ATI 5770's in crossfire and I'm on Win 7 64 bit. My mobo is the Asus P6X58D-E. Just wondering how would I go about to change/configure the cards to run at 8X or 16X (whatever is feasible within Crossfire on this mobo). I've googled around and haven't really found any solid answers.

Thanks in advance!

The smaller pci-e slot is 1x speed. The others ones on your board used for graphics are 3 x PCIe 2.0 x16 (at x16/x8/x8 or x16/x16/x1 mode). You can select the speeds in your bios.

Thanks, I did download GPU-Z and it shows my crossfire cards running in PCI-E 2.0 X16 so everything is fine.
