Hi suzanneg,
This is exactly where I got my info about building a rig! Best tutorial I could find so far!

The difference is that I intend to use 4 GPUs with 4 powered PCIe 1x to 16x risers.
Hi cryptoprime,
Yes I'm considering doing this, but I can't find info from owners of the same mobo.
Do you know if I can safely short a PCI x16 slot? I found infos about shorting a 1x slot, but nothing about the 16x slots.
Also I read stories from people frying their mobo shortly after shorting their PCIe ports... simply horrifying..

What psu are you using?
Hi justkid,
I have two Akasa Cobra 850w running on the same rig, which are intended to power two GPUs each. With a total of 1700w, I think that might not be the issue.
I dont know for sure, but a PCI x1 slot just got about 500Mb/s in each direction and my solo mining gpu produces a heavy amount of traffic. when start copying files between 2 harddrive's while mining, i just got half the i normally got.
