Another way to "test" it is to OC the machine in the BIOS. THEN run
the test(s).

A bad stick will show up pretty quickly.


What's OC?

Mobos should have some memory test hardware. Some like mine even have TDR's
to tell you how long your ethernet cable is, which is useless.

For comparison, here's part of an interview with the devolopers of the Alto
at PARC.


The Analytical Engine, Volume 2, Number 1, July 1994 Page 20

CS: They had this neat software that would run every night,
called DMT. And we had a dedicated Alto called Peeker, remember?
And each machine would be left with a kind of screen saver
running, a square that moved around and checked the memory in
all these different locations. And if it got an error when it
was doing this little test, the Peeker would log it.

HY: It was a memory diagnostic that ran overnight. I'll tell
you this. The first Altos had these Intel.... I didn't think it
was going to make it. The 4K chips when they came out were
really okay, reliable, but the 1K Intel chips -- 1130's --
weren't.

CS: Every morning we would check, and anyone who had a bad
chip, we'd go in. The nice thing about it, so many of these
software people didn't know they had a bad or a flaky memory
chip, and a lot of times we'd say "We have detected a bad chip
in your computer and we'd like to change it." And they'd say
"Oh, wonderful!"
