Not prime95, but requires an AMD dual-core driver.

Stopping (Test > Stop) prime95 manually then restarting it (Test > Continue) would cause an "ERROR: ILLEGAL SUMOUT" once in a while (perhaps 1 out of 10 times).

Download the latest version of "AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (exe)" from here:,00.html.
This driver does more than manage Cool'n'Quiet even if you have disabled Cool'n'Quiet in your motherboard BIOS.

Make sure affinity is set for each instance of prime95 and the stop/restart of prime95 should be fine.
