First thing i would like to say is if you help me solve the problem that i am having a will give you 1 copy for dirt 3 that i recieved when buying a 6970, if multiple people help, i will give out multiple copys, I have 4x extra i do not need. If you like fg better i can buy some. NOTE: This is for a gaming computer, not bitocoin mining, or any other shenanigans. Motherboard: I have a p7p55d-e ASUS mother board. Here is the link to the EXACT one I have: ASUSTeK Computer Inc. - Motherboards- ASUS P7P55D-E Problem: As you can see the motherboard has 2x 16x PCIe slots, One blue, One dark grey. ANY ATI card that I put into these slots runs at 4x speed. (seen VIA GPU z latest version) ANY NVIDIA card i put into these slots runs at 16x speed. Needed Solution: I need to get ONE ATI card to run at 16x Bus interface. ATI cards I have: 3x 5770's (xfx) 1x 6970 (currently being RMA's (replaced) by Newegg) (xfx) Nvidia cards I have: 1x 460 (evga) 1x 465 (evga) What I have done: Latest Bios has been installed (Battery taken out full reset has happened) Cleaned Both pcie slots and pins on both ATI cards Other information: I have a i7 860 (no overclock since bios update) 8gb of DDR3 ram (checked for errors no problems with any sticks) 850w Power supply (new) Any help would be greatly appreciated.

Expansion Slots 1 x PCIe 2.0 x16 (single at x16) 1 x PCI Express 2.0 x16 slots (@x4 mode, 2.5GT/s, black slot) 3 x PCI Express 2.0 x1 (2.5GT/s, gray slots) Link to comment

So your only option is to plug in the Top dark blue slot for a single GPU.... So if you want to Crossfire one card will run at 4x mode... It's on the mobo's website under the ATI symbol...that fucking sucks it's like they put a disclaimer on their box... ASUSTeK Computer Inc. - Motherboards- ASUS P7P55D-E Sorry bud. Link to comment
