CTD Cat and Mouse resolved with happy surprise

So, without using MSFS as a “TEST” and potentially introducing false issues, is there any “test” program that can be run, to “stress ?” the ram as it is stressed in MSFS, and verify if there is a hardware ram issue.

Ie Is my PC “stable” enough for the stresses of MSFS", where you could leave it running for hours, with the aim of getting to a setup & settings where it is rock stable, – and better than running MSFS, where if it does “Glitch” or CTD, you have no idea why .

Like Memtest86, but with high stress.

Something that cab identify & tell you that a specific Ram Module is acting up ?
