I keep getting a BSOD saying something about,second core did not get an interrupt on time.I have RAM @ 5-5-5-15 and I stepped up v to 100mV.
There are a lot of settings here that I do not understand so,I leave them at auto.Running @ 2.9 now.
Cyber, I've been running at 3.0GHz without voltage bump for a few weeks, with just the multiplier set to 15x in the bios. I left everything else on auto - no FSB adjustments, no manual HT adjustments, no memory timing tweaks at all. The DDR2-800 Kingston ram I have runs at 5-5-5-18 in auto mode. With these settings, I can run Prime95 all day long and get no errors, either with my Zalman or the stock AMD HSF that came with the Phenom 9850BE.

Just tonight, I decided to bump the multiplier up to 15.5 (3.1GHz CPU clock rate) and I had to give the chip a slight bump up in voltage to 1.36v (from the stock 1.29v). Running prime95 torture test on it now with the stock AMD HSF, and getting CPU temps of up to 60C. One of the cores just gave me a rounding errror. I'm thinking of getting a better aftermarket HSF. Maybe a Thermalright 120 Extreme or a Sunbeamtech Core-Contact Freezer.
