Hmm... Well, Reading your previous reply, I checked to see and my DIMM is
made by micron, so thats not the problem. Ive had a wierder problem at
work. I use a FreeBSD machine as a NATd gateway to route a campus lan
to the internet. The box had only 2x8mb simms, and there came the upgrade
time. We bought two new micron sdram chips, 32MB each. When Ive tried to
install them both, FreeBSD wont reboot. Ive read something about that in
the mailing lists. When I remove one chip, it works perfectly.
so I left the two old SIMM's in there and now the box has 48MB of ram.
works perfectly running 2.2.6-BETA and has weeks of uptime, Never crashed
on me.
