Hey guys,

I am trying to use 5 AMD RX570 GPU on the ASRock H170A x1/3.1.

In Windows 10, all 5 cards are detected, 2 are usable, 3 are in conflict due to lack of resources (CODE 12). Windows suggests to disable other devices on the system.
I have updated the latest BIOS, turned off unnecessary features like onboard sound and scaled back the PCI-e to generation 1.

After spending countless hours researching and tweaking setting, reinstalling drivers, i have thrown the towel.
I have also tried Windows 7 and Ubuntu unsuccessfully.

I have 4GB ram, G440 Intel CPU, 128 GB ADATA SSD, 5 MSI RX 570 GPU, 1050 Watt EVGA Power Suply.

Any suggestions are greatly appreciated! ]]> Mon, 10 Jul 2017 12:55:55 +0000 https://forum.asrock.com/forum_posts.asp?TID=5542&PID=32476&title=5-gpu-support-on-asrock-h170a#32476
