Hi,
I have a rig with 3 GPUs:
2xAsus Dual RX580(with modded bios)
1xSapphire Pulse RX570(no bios modification)
Motherboard: Asus H81m-pro with 4GB of RAM.
I'm trying to add one more GPU(Sapphire RX570) but with no luck. I checked all of the risers-OK, all of GPUs are working since I tried them one by one. My OS is Win10 and I'm using latest blockchain drivers from AMD. So, I tried DDU and clean install but no change, 4th GPU isn't showing up in device manager. Sometimes fans of this card starts to spin at maximum speed when I power on the rig and stays like that until I do windows reboot.
I checked bios settings but there's nothing particular to indicate this issue.
Only thing left is to reinstall windows but I think doing that would not fix the problem.
Does anyone have any idea what can I do to fix this problem?
Regards.
