Stumped in Florida. The new SIMM is also bad. I suggest finding another supplier. FreeBSD tends to work memory more vigorously than other systems (including Win95 and Linux) so hidden memory errors are more prevalent. I'd check your timings in BIOS setup and slow those down as well. Bad processor cache RAM will also cause erratic behavior.
