If you use current memtest86+ (notthe original memtest86), there is
an option to use all cores (F2, I think) but you need to be quick to
take advantage of that or the message about it will disappear from
the screen.  It is off by default because on many machines (including
all of those on which I tried it) the box will lock up hard after not
very many minutes in one of the tests (around test number 7, if my
memory serves).  While it runs you will see a |/-\ sequence spinning
on each CPU, instead of just on the first.

It might also be that memtest does not exercise whatever part of the
machine is failing.

Nanny Ogg usually went to bed early. After all, she was an old lady.
Sometimes she went to bed as early as 6 a.m.
