Something i noticed today. From what i have read about this board you shouldn't need to increase NB voltage until you start hitting 500+ on the FSB. I had mine at 1.30v and tried turning it down to 1.25(forgot i had raised this before increasing the voltage on the CPU). Well..... not such a good idea. I blue screened out of nowhere after a few minutes of booting into windows. So I cranked it back to 1.3v. No problem. Just to make sure i put it back to 1.25v. Problem returned. I thought it might be RAM undervolted or timings too tight. Loosening timings and increasing voltage to ram did no good. Sure enough the NB voltage was the culprit.
Just a heads up to others out there that think they are hitting a wall too fast when overclocking with this board. It appears you may need to increase NB voltage before hitting 500fsb.
BTW this is at 3.2ghz(8X400)CPU with 1.42v and RAM at 800mhz with 2.0v.
White ram slots also appear to be the ones to use. Experiencing random hangs at POST when attempting to use blue slots only. At the same settings the white slots do not give me issues.
Got it to boot into windows at 3.4ghz @1.45v. Orthos failed after minutes. Looks like it may be doable on slightly higher volts but more then i would want on a 24/7. Looks like i'm gonna be at 3.2ghz for my 24/7. Kinda bummed but still not a shabby overclock. I'll keep tweaking but i think that may be it for this chip. L650C690 -- Not bad. But not great.(just like my opty..... damn)
