Which pcie 3.0 X16 can I use for a single GPU?

[nightmarevoid]

I'm planning a build for a friend, but the most optimal way to use the the two PCIe X16 slots would be to have the graphics card in the slot farthest from the processor. In the past, this has caused intermittent driver crashes from Nvidia. My last attempt at using a pci express X16 slot other than the top one was back on pcie 2.0. Can I use the lower of the two PCIe 3.0 X16 slots without any problem? I'll link the motherboard's New Egg page below.

I would just use the top PCI-E Slot.

putting a gpu in the top slot shouldn't make things crash

 

it shouldn't matter which one it is in for it crashing but i would use the top one

Only the top PCI-E slot is wiered for PCI-E x16 the second slot is x8 and the bottom slot is x4.

Normally the first physical 16x slot is wired electrically for pci-e gen 3.0 16x then it splits into 8x by 8x since the 4790K/4690K/Z97 chipset splits the bandwidth. If you go to the asrock website and look up the manual for this motherboard you will find how the pci-e lanes are split up,

I tried the manual download page again, and after two attempts the manual downloaded. I opened it up and you are correct, the second pcie 3.0 slot is wired for 8x. I'll use the top slot, but I wish I didn't have to because it'll look a little weird putting one or two X1 devices in X16 sized slots. But oh well, it doesn't matter too much. Thank you all for the help!
