How to test RAM?

Extracted from debian-user
Tip provided by Alexander Kushnirenko
Just want to share my experience with memtest86.  I had a bad memory module,
as I found out later.  There are 2 ways of memtest running: as a boot process
and from inside Linux.  Installation of memtest86 as an independent boot
process (you can have memtest in your LILO - Linux, Dos and MemTest for
example) DID NOT catch the bad memory module - it reported that everyting
was fine.  On the other hand running memtest from Linux (then you have to guess
your free memory right and give it as an argument) indeed reported the
problem.  So I would recommend running memtest in both modes to catch the
bad memory module.
Well, in my case I started to beleive that memory was OK only when X
stopped to crash spontaneously on me :)

(memtest86 is part of the hwtools debian package, and called memtest)
