Hi Peter, I will check the BIOS firmware. I haven't tried that yet. I'm running FreeBSD 9-RELEASE-p3. Yes it is AMD64. I ran memtest on the first 32 gb or memory where the machine was initially stable. Once I put over 64 GB in, I can't get the machine to stay up for long enough to even try. I'll try the verbose boot idea too. Thanks!
