Title: Please HELP!!! I can't mount more tha 3 GPU !!! Gigabyte R9 290 Windforce Post by: konarix on February 08, 2014, 12:43:26 PM 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. Title: Re: Please HELP!!! I can't mount more tha 3 GPU !!! Gigabyte R9 290 Windforce Post by: konarix on February 08, 2014, 06:50:01 PM Anybody?
Maybe some settings with cpu in BIOS? Title: Re: Please HELP!!! I can't mount more tha 3 GPU !!! Gigabyte R9 290 Windforce Post by: Starscream on February 08, 2014, 07:12:41 PM 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. Title: Re: Please HELP!!! I can't mount more tha 3 GPU !!!
