I recently discovered my once-stable memory overclock had become not quite stable. I decided to run a memory test and it was almost stable, but after a few hours i got an error (with a single incorrect bit). So I retuned it and want to throw the most tortuous stability test I can at it to make sure it passes.
The system runs linux, which means the standard goto recommendations on windows may not be available. So far it has passed many hours / several test iterations of:
* memtest86 10.6 pro (from bootable flash drive)
* memtester (running in linux) – I loaded up 28 parallel memtester processes (memtester is single threaded, so 1 for each logical core) and gave each 4200 MB to work with (which, combined, is ~115 GB, leaving 8-9 GB for the rest of the system).
* stressapptest (running in linux) – a couple of hours with options (as defined [here](https://manpages.org/stressapptest): `-M 80000 -H 60000 -i 28 -m 28 -C 28 –random-threads 28 –cc_test`
I know the following stresstests exist, but havent yet used them:
* the stress tests listed in the [arch wiki](https://wiki.archlinux.org/title/Stress_testing) minus any listed above
*S-TUI
* stress-ng
[phoronix test suite](https://www.phoronix-test-suite.com/) probably has a few more as well
Which of these options is the most brutal / most likely to discover any memory issues in the shortest time possible?
Thanks in advance.

Side question: I almost feel like with b-die I should be able to tighten some of my timings more, though there arent really any guides that consider a “quad channel 8x16gb” configuration, which is somewhat more demanding than the typical “2 sticks in dual channel” configuration. Do any of the memory timings look obviously less-than-optimal?
