[SOLVED] Can't Run Prime95 Large FFTs test

[barnyard80]

What does it mean if I can't run the Prime95 Large FFTs test.

My CPU is a Ryzen 9 3950X.

After a few seconds, I get a "Killed" message in the console.

The CPU is not overheating, as it is still below 60C at that point.

The computer has been running fine for the last month. I notice no instability.

I can run the Small FFTs test fine (I've probably never let it run for more than 30 minutes, but at current settings the CPU temp stays below 70C anyway).

Accept the answers above? (Y):

Possible RAM stability issue. Try running Memtest86.

Thanks for the tip.

I didn't feel like installing Memtest86 and rebooting. But according to this, Google's stressapptest is similar.

That fails if I run it on default settings, but I think that is because it is targeting 30GB (of 32GB RAM), when only 16GB is free.

The test runs fine if I target 16GB of ram, so hopefully everything is fine.
