Except for some very specific cases (like watching signals on a scope
while running the test) memtest is almost totally worthless.

Once upon a time, "PC" meant "personal computer".  Now  it  seems  to
only  mean  "Prisoner  of Bill". Alas! All my PCs run Unix, and those
include Intel, Sparc, and other processors.
