Memtest doesn’t tend to get your CPU hot, though. Different things can fail at different utilization levels…

There was that prime-something program i remember using a long time ago for that, not sure if there are more modern solutions
ycruncher?
I remember prime95 but maybe that was like 20 years ago
damn im old
whatever type of error you are having must be a more widespread issue than a few pages to be triggered so often
the ideal program would have a small pool it nonstop allocates to and deallocates from and a pool it very slowly checks and rotates allocations in/out
write random data and CRC it as I said
you then want to stop the process and get a debugger if there’s a mismatch and see the physical location along with identifying the RAM module
Prime95 will definitely get a CPU toasty, but you would need to ensure it's running with a mix of large and small FFT and for a while (e.g. hours/days). Small FFT maximizes CPU heat, but isn't the best for finding instabilities working with RAM. Large FFT helps there. In general, I find the overclocking community sometimes works on "vibes" rather than completely proven test methodologies, so take this with a grain of salt.
not that you're overclocking, but that group tends to accumulate tribal knowledge of CPU/RAM stability tests. Hardware can be "fun". A ton of variables. Even things like bios versions can cause instabilities.
