Just curious, are you running the PDC34G1333LLK memory kit (http://www.newegg.com/Product/Produc...82E16820220278)? Were you getting errors/BSOD when you left it as the manufacturer listed 1.7v at default (no OC) speeds with your QX9650?
Edit: Just noticed you're running the 2GB kit...wonder if the voltage would vary with the 4GB kit (as I'll be running x64 xp)
