Commonly referred to as "Prime95" in the Windows/OCers world, the Great
Internet Mersennes Prime Search client is a very good indicator of system
stability. It has a generic "burn in" mode you can run and a mode that
actually searches for primes; it can be found in ports/math/mprime. I run
an instance for each CPU on my A7M266-D (w/ECC), and it's pretty damn stable:
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND
55725 green 155 36 17372K 15104K RUN 0 606.1H 78.91% 78.91% mprime-real
27850 green 155 36 14532K 12228K CPU1 0 662.7H 76.81% 76.81% mprime-real
