Xorg and Plasma With Hybrid GPUs Crash frequently

I have a computer with 2 Radeon HD 4890s, I'm using the ATI driver and PRIME for hybrid graphics.
It constantly crashes, I see diagonal or horizontal stripes, black-white, blue-navy blue, and sometimes shades of orange.
I think it's only the graphics cards because one time it crashed while I was installing something with pacman mid download and I waited for a bit to shut it off and when I booted in the installation was complete.

Here is the output of journalctl after a crash: ix.io/44EV
And here is the output of smartctl for the main drive: ix.io/44Fa

It happens when I try to open the KDE System Monitor, gmail with firefox or it just happens by itself after some time.

Re: Xorg and Plasma With Hybrid GPUs Crash frequently

What exact journal command did you use to produce this? To get anything logged from a crash you need to use e.g.

journalctl -b -1

to get the journal of the boot prior to your current (working) one and I don't see any errors in that output on a quick look.

It crashed again and I took another journalctl (from last boot like you said)

Re: Xorg and Plasma With Hybrid GPUs Crash frequently

Looks like only the GPU in bus 2 is having issues, can you reproduce without that, e.g. only running stuff off of the other card/unplugging that one? I'm assuming that's the "main GPU"? Is the card properly seated? Is there a particular purpose or intent behind running two GPUs or is it "just" offloading games?

I didn't build it, it's actually a pre-built (some old cooler master cnotase) render station (I think) hand-me-down. I will try with one card and I don't think the one on bus 2 is properly seated but I will check that too.

I don't have any hybrid configurations setup right now, I've just been trying to fix issues for the last two days.

I took out both the GPUs and cleaned any dust and put only one of them back in, now it works fine.
I will try to put in the other one when I have free time
