Building 4x GTX 1080 recommendation

[kiara]

ok i'm late but it might be good for people who are planning to build such a thing.

So if you mean ROG RAMPAGE V EDITION 10 i gotta say no. you can't achieve what you want.
i have not tested but from what we can find out from specs here:
https://www.asus.com/us/Motherboards/ROG...fications/
with a Core i7 5820K you can't get 4x gpus to work.

Look at expansion slots part:
4 x PCIe 3.0/2.0 x16 (x16, x16/x16, x16/x8/x8, x16/x8/x8/x8 or x8/x8/x8/x8 mode with 40-LANE CPU; x16, x16/x8 or x8/x8/x8 mode with 28-LANE CPU)

The 5820k only supports 28 lanes so you are going for x8/x8/x8 mode at most!

The RAMPAGE V EXTREME also has the same problem.
I would be happy to hear any opposite ideas.

hashcat work perfectly with x4 . i dont see any problem with that.
the problem can happen if u try to mount big dics, but even that x4 is enough to load it all, 
if u would use a riser the problem above could apply u, but x4 is good enough
some one correct me if im wrong
