Hi.
Thank You for answer.

I got win 8.1

I have bought 4x PCIx1 and 2xPCIx16 without molex because it is my first RIG  Undecided

So Do You sugest to place 2 GPU directly to mainboard to PCIx16 and other two on risers x1 ?

Thank You.

Anybody?
Maybe some settings with cpu in BIOS?

Try Windows 8.1 if you haven't already.

BTW, why you using the x1 and without molex? You got 3x PCI-e x16 connections, you could easily utilize 2 of em with enough room in between.

Hi.

I can't mount more than 3 Gigabyte R9 290 Windforce.
Windows freeze during installation of drivers for fourth card.
Have tried with 13.2 and 14.1 drivers.

Bamt won't start with 4 GPU too.

Main board is MSI Z87-GD65 Gaming.
I have tried on Z77A-G43 - the same problem.

All cards on Risers 1x and 16x (without molex).
Two PSU 1000W each.
8GB of RAM and Intel G3220.

Can anybody help me?

BR.
