Well, don't put your GPU in the second slot like I had. It was only there temporarily thus I didn't notice the x4 slot.


Interesting, Inverted ATX. Top heavy for my HDD needs though.

"".... not enough room for the pump between the GPU and bottom radiator.""

Huh? There looks to be plenty if your rad is mounted at the bottom.

It looks like the PCIE2 slot is an x8 slot electrically, while it is x16 physically.

The difference between PCIe 3.0 x16 and PCIe 3.0 x8 is said to be about 1% difference in performance.

Only the x16 slot closest to the CPU socket is x16 electrically.

EDIT: The PCIE2 slot is only x4 electrically according to the specs. The PCIE4 slot is x8 electrically, the PCIE2 and PCIE6 slots are x4 electrically.

On the z170 oc formula, with a single GPU card, can any pcie slot be used or does it have to be the slot closest to the CPU?
