I have booted into windows before at 3850 mhz but It failed prime pretty quick. Even tried upping voltage one time to 1.475 to run 3650 but it randomly rebooted on me again. I figured It was memory issue so thats why I was searching for a better set than my patriots.
dont know why but with the patriots even If i lower them to the x4 multi and run like 800-900 cas 5 i still error out or reboot in prime at 3580 and above. With the low volts I was good up to 3605. to me thats wierd that the memory can make the cpu overclock better but I stil think i have to be either really bright but dumb at the same time because I understand the basics but cannot get my chip higher, or either I have a crappy overclocker. Also I am using x64 vista and a lot of folks said that its rare to get a chip in the 3700 and above range for a long time stable with that os??? BS or fact who knows.

Also what I was considering stable was 24+ hr prime blend/linX 150 passes 10000/linX 150 passes max memory/OCCT 24 hr. That may be extreme I know but I did'nt find a lot of the higher frequencys unstable till wayyy into testing.
Whe you say Vcore @ 1.45v you mean the CPU correct..

Well the setting for the NBvid needs to be @ +100 to +200 minimum for any 720 @ 3500mhz+ with X4core on Air or water for the IMC to not error while running variouse rams.

If you have not raised the NBvid which is set @ 1.1 -1.2v stock you must raise it to +100 = 1.3v or even +150 = 1.35v or even +200 = 1.4v..ON THIS MOBO.

Numerouse users have run +200 or higher for the NBvid to stay stable even @ 3600mhz x4 and low Nbclocks.

720's need the higher NBvid volts when using DDR2 vs DDR3 even with just two dimms x 2gigs 4gigs or 4x1gigs.

The DDR3 IMC is a lot stronger on 720 than the DDR2 IMC. This may be why the 720 isnt deemed a X4core. Because of a weak DDR2 controller who knows.. Ive also found that people have clocked them higher in AM3 Mobos and with AM3 ram better than with DDr2.

My same 720 will run 3800mhz X4 Nb @ 2600mhz DDR3.
but barely does 3700mhz with DDr2 and 2400mhz nb.

Too bad it wasnt my Mobo and DDr3 that i tested it with ,, always setting up stuff for friends dang it.
