What motherboard BIOS version are you running?
Try updating the motherboard BIOS.
45nm chips weren't compatible with the bios versions that shipped before the 45nm chip was introduced.
F8a might do the trick if you haven't already done so.
And I'm waking up for work just as I expected - 9 hours of Orthos and still going.
If my ram couldn't handle 900mhz - would Orthos run for 24 hours? Or should Orthos strictly be used to test a FSB / CPU overclock?
It's just weird because it runs @ 3.6ghz ...a 600mhz overclock - with no change to voltage. It's like it wants to be running at this speed. But the second I try to go to even 3.8ghz it wants at least .075 extra vCore. Today when I get home I'm going to experiment higher FSB with an 8 multiplier. Maybe I can hit 500mhz with some cooling on my northbridge. Not exactly the route I wanted to go but I've heard of a few people with this board doing it.
I'm off to work and going to leave Orthos running - It should be at about 21 hours if it keeps going until I get home. I'll consider that stable enough for me to consider this a possible 24/7 overclock, just a few hundred mhz lower than I had hoped.
