Yes, the old days are not forgotten! Looks like you have a solid chip there!
This is only my 5th LGA 775 chip so this stuff is all relatively new to me.
I'm going to see if I can push the CPU a little further and I'll come back with some torture test results.
The problem I'm facing right now is if I go above 500 on the FSB I have to do a manual reboot. That is, shut down the system, switch power off and then back on again.
