Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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!
