I have my Pentium D overclocked to 4.0 GHz up from 2.66. I can do SuperPi and normal tasks without any problems. But when I run ORTHOS it just restarts. So there is something unstable about it and I don't know what.
FSB 533 OC'd to 800
Vcore at 1.5
RAM is left to default, 667
all auto timings (5-4-4-14)
But That's the thing, I can't do orthos for very long at all. Maybe 10 minutes until I get an error. I can do superpi except for 32 million. I had it start and walked away and came back to a restarted computer haha.
