But also note that a memory test passing doesn't mean the ram (or CPU) is fine.
I overclocked my system for fun and for ram you'd run 2-3 different tests to be able to call it stable with some confidence, as they all have different access patterns and r/w ratios.
Memtest86/+ are usually seen as worse compared to the other tests like say or karhu ram test or testme5, but those also need an OS to run and in the rare chance only some region of memory is faulty could miss it
Testmem5 is in a league of its own yet its unclear how. Maybe the AWE table is prone to corruption. Theres nothing special about the internal workings. It doesn't use fences or clflushes.
