Ubuntu specific RAM issues – chrome crashing and memtest86 freezing

G’day,

I’m running 4x8GB sticks of corsair vengeance LPX RAM, a 5700xt and an r5 3600x.

I just installed ubuntu 20.04 a week ago to dual-boot with windows and I’ve been having RAM-related problems. Google chrome pages have been crashing with the aw, snap error: SIGSEGV. Chrome will also completely crash if I have too many tabs open. I ran memtest86 from the ubuntu boot menu and it freezes at 16% on the first pass when I have all my ram in and 35% when only 2 sticks are in (doesn’t seem to matter which two sticks or which DIMM slots, either). I’ve yet to be able to get past 2 seconds into a memtest86 test.

I don’t have these issues when I run windows as the OS and the Windows Memory Diagnostic didn’t return any errors. It seems like the issues come when I try to access more than a certain amount of RAM in Ubuntu but I’m not sure.

The command free -m shows the amount of memory i’d expect.

Does anyone have any thoughts? I’ve tried installing PPA drivers for my GPU and had a look at the latency timings for my RAM in the UEFI but no luck.

Cheers.
