Hello. I got my system a few weeks ago:
Intel Core2 Duo e7300; Arctic Cooling 7 applied with Arctic silver 5; Gigabyte EP45-UD3R; Patriot Viper DDR2 800 2x2GB 2.1v 4-4-4-12; Antec TP2 550W ATX PSU; Seagate 7200.11 500GB; WD 80GB x2; and Samsung 22x dvd burner w/ lightscribe; MSI 8800GT 512 OC
My problem is I cannot seem to find any setting past 3.33ghz that is stable. At this setting I can run Prime95 & memtest for hours without a problem, but 3.4 or 3.5 or 3.6 all either BSOD while windows is loading or fail prime95 pretty quickly. I have done several voltage increases across the board and once again 3.33ghz is stable with the following settings:

I have tried very loose memory timings and even small clock increases seem to at the very least fail in Prime95 with "rounding errors." Also with voltage set to '1.32500V' in CPU-Z it says 1.296V idle and 1.280V load with same numbers in EasyTune6. I know there is vDroop but other posts seem to show a tiny number not 0.029V difference idle and 0.045V under load. Do I need a better PSU or...?
My goal is to be running around 3.6-3.8GHz stable and since I got all these components for OC'ing I am hoping to have my memory running at about 1000-1066mhz.
Thanks!
