Hi folks, I just installed two Radeon 6870s on a mATX Gigabyte GA-Z68MA-D2H-B3.
While the MB officially "supports" SLI and Crossfire and has four PCI 2.0/3.0 slots running at x16, x1, x4, and x8 (in that order, left to right), you can only plug in the cards in the two slots (x16/x4) that "support" dual GPUs and that can "fit" in the case since those cards+coolers are pretty big and hog up both slots.
1. I noticed on GPUz - even with full-screen/power my setup runs at x16/x1 instead of x16/x4. I searched all over for this and couldn't find out why... is it incorrectly reported? Is it because I'm using all 6 SATA devices? Any other ideas? I assume that x1 card is causing quite the bottleneck?
2. That being said, any recommendations on mATX boards (socket 1155) with x8/x8 or even x16/x16 SLI support?
Thanks in advance.
