I have searched and searched and cant find a solution. The other day i just finished building my new pc asrock z77 extreme4 mobo i5 3570k at 4.5ghz 16gig gskill aces series and a few other things from my old pc. I am running 2 sapphire 6870s in crossfire i reused from old pc for now. But i am seeing a few issues with frames in games so i decided to check my gpus.
The issue i am running into is that the first card is pci 2.0 x8 and the second card is running pci 2.0 x2. As far as i know and according to the owners Manuel its supposed to be running at x8 for each.
I have checked both cards by swapping them trying 1 by 1 and checked the power supply. both pcie slots run at x16 with only 1 card in. i have reinstalled drivers and cleared them multiple times.
I have also read that usb 3.0 and sata 3 can steal buss speed from pci slots? anyone know if that could be my issue. Thanks in advance everyone.
