Except simm checkers don't always catch errors, so if the simm passes, there still is no guarantee (but simm checkers do weed out obvious duds quicker than trying in a system). Unfortunately, there is no conclusive test [that I know about] to prove a simm is "good". The best test I know is to use emperical evidence based on how the system acts with or without the suspect simm. Even better is to only use motherboards that support parity and/or ECC, with parity/ecc simms/dimms. Then you catch most problems right away, rather than scratching your head (and doing the "if I twiddle this knob, it seems to reduce the problem... I think"). -- Zach Heilig / Zach Heilig To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
