I recently built a big big box to play around with, running VM's & Jails & such, & test benchmarks & do whatever else I thought might be fun on a computer. I overclocked the processor a little (what's the point of having a Black Edition chip if you don't?) & got it to run FreeBSD 7.2 amd64 stable at 3.8 GHz, but when I bump it up to 4.0 GHz, I get thrown into a reboot cycle. It just reboots after it recognizes my hard disks, no kernel panic or anything. I'm using the GENERIC kernel & haven't started messing with stuff (it's a clean install). If I bump the processor back down to 3.8 GHz it runs perfectly fine (ran it over 24 hours straight w/o any problems). My Motherboard won't let me overclock past 4.2, it throws an error in the BIOS about it, so the hardware can handle 4.0. Does anybody have any idea why FreeBSD would do this? It's not a big deal, I'm just curious. Would there be some way to capture what's going on? I tried to save the core dump from it, according to ch 10 of the developers handbook, but on the next successful boot, there's nothing in the /var/crash directory.
