Gtx 580 Sli showing up as PCie x16 @ x8

post #1 of 19
Thread Starter 
I just installed the second gtx 580 into my sig rig and enabled max performance in the NV control panel, as well as turned off USB turbo and 3.0 controllers because I read the UD7 board uses some pcie laves for those, and it still states the gpu2 is running at x8, There is nothing else on the pcie bus on my system. There is a sound card running on the pci bus, but that shouldn't matter.

I thought these boards were supposed to do two x16 cards and x16, x8, x8 for three...

No Z68 or P67 board does x16 in multiple PCI-E lanes when in SLI/Crossfire, it's a chipset limitation. It doesn't really matter, it makes no difference in performance. [H] did a test comparing the different PCI-E speeds if you wanna see.

Edit: On Newegg it says your board can do 2@ x16, but I don't think that is correct. I am pretty sure it's a chipset limitation.

They did the same thing with P55 boards (like the P55 Classified 200).

There's no LGA 1155 board that can do x16/x16, they don't exist. Older boards such as X58 can do x16/x16. That's not a chipset limitation, they simply don't want to add 2 PCI-e x16 lanes.
