SETUP:
win10x64, HDD
Mb: ASUS AM3+ SABERTOOTH AMD 990FX R3.0 ATX Motherboard - Black
PSU: EVGA 1000 W GQ Series ATX Modular Power Supply with Active PFC
CPU: AMD FX 8350 Black Edition "Vishera" CPU (8 Core, AM3+, Clock 4.0 GHz, Turbo 4.2 GHz, 8 MB L3 Cache, 125 W)
GPUs:
Gigabyte Radeon RX 460 2GB
Gigabyte Radeon RX 550 2GB
XFX Radeon RX 550 2GB
Asus Radeon R7 240
ATI Radeon HD 5770
ATI Radeon HD 5770
I'm connecting all of the with risers. I should have enough energy through my PSU, and I'm trying to connect them through as many different cables from PSU as possible, so as not to have any 'slave' GPUs (I don't really know if that's a thing. It used to be on old PCs years ago).
As much as I try different variations (even connecting only the top three GPUs in and leaving the crappier ones out), The XFX 550 and Gigabyte 460 keep shutting down once I get into Windows, and even getting in is a problem, sometimes the OS just shutting down, sometimes remaining on a black screen...
I tried different drivers, but I can't seem to get them to work. And my system can't seem to become stable. What am I doing wrong?
Please, feel free to follow up, I know I haven't given enough info, I'm just so frustrated. I've been working on this setup for more than 20 hours now, trying to troubleshoot it, but I can't seem to solve it.
Please, help me
