Specs (From CCC)

 

Radeon Software Version - 17.7.2
Radeon Software Edition - Crimson ReLive
Graphics Chipset - Radeon (TM) RX 470 Graphics
Memory Size - 4096 MB
Memory Type - GDDR5
Core Clock - 1250 MHz
Windows Version - Windows 10 (64 bit)
System Memory - 12 GB
CPU Type - AMD Phenom(tm) II X6 1100T Processor

 

 

Okay, I need some help. I am having a weird issue where any fullscreen game will completely lock up my computer, but only when crossfire is enabled.

My PSU is an EVGA 750W model and practically brand new (recently replaced my old power supply for cable management reasons)

 

games run just fine on a single card, or in windowed mode.

All clocks are stock.

Sounds like some sort of bug, try reinstalling drivers and then reverting to a previous version. Make sure your pcie slots are running in the ideal mode for crossfire (I'd advise at least x8 on both). Try running both cards one at a time to see if either has a problem.

Don't ask to ask, just ask... please 🤨

sudo chmod -R 000 /*

Unfortunately, one slot is limited to 4x, however it was not a problem in the past.

In theory it shouldn't be a problem, but hey, you never know. If it worked fine in the past I doubt that's the issue anyway.

Had similar issues, but didn't matter single or multiple GPU. Reinstall to earlier version. The new one doesn't work well.
