PCIe 4 is connected as an x8 slot, if you look at the back of the motherboard you will note that only PCIe 1 is electrically connected as x16.

Thanks Xaltar!
Any guess as to whether it would run at x16 in PCIE4? The manual isn't very clear on these things!

It is a PCIe device and so should work, even in a PCIe x1 slot (if it is an open ended "flex" slot) so yes it should work fine.

In the manual (http://66.226.78.22/downloadsite/Manual/Z170%20OC%20Formula.pdf) it states that I can have a single GPU in the PCIE1 slot and says 'N/A' for the other slots, but I'm wondering if this means that I can't put the GPU in the PCIE4 slot?
The reason I'd prefer to do this is because the GPU will be difficult to remove with my cooler (NH-D15) in the PCIE1 slot, and even if it only runs at x8 in PCIE4, my research suggests it will only be a 2% performance reduction in most applications. Anyone know? Thanks!
