E6400 @ 3.2GHZ with GA-965P-DS3 Issues!

Are you OC'ing it from BIOS or OC'ing from within windows? I hear alot of people getting better OC from within windows but then it doesnt like to boot at those setting and reverts back to stock freq.

I have the same problem on my E4300, GA-965P-S3. When I first set up my OC, it boots into windows just fine at Stock everything except FSB 266. It then runs just fine until I try to reboot. Then it doesn't post and resets the bios back to stock...Doesn't make much sense to me that it would work fine in windows at FSB 266, but can't reboot even at FSB 220.

The only reason it'd reset back to default FSB would be that your computer was unstable, and forced to reboot/stall, the bios would detect it and reset every back to default.

I had the same problem with S3 and DS3, while Prime95 and MemTest proved to be stable for days, but still reboot with default settings, and still couldn't fix it with latest bios reset, so I decided to try different things, and got it fixed when I had the Vcore increased 1-2 notch higher than the currently level.

The other thing is, you need 2.4V for your Vdimm? That's +0.6V, but if I'm not mistaken DS3 would allow only +0.5V?

Anyway, you said it seems to be stable 24/7 and you got it on for 1 week, did you do stress test the CPU long enough to verify it's 100% rock solid stable? And did you try doing MemTest? What power supply are you using? Did you observe the change in Voltages between idle and load, and are the voltage stable? How about temperatures? I saw on your picture you got Orthos running 5+ hours without problem, believe me or not, on many occasions when I'm on the border line of 100% stable voltage, my system seemed to fail after 10-15 hours of testings, and usually 1-2 notch increase in Vcore fixed this problem.

So, you fixed the problem?
What did you do?
I'd let it run for 24 hours, do a max CPU stress, and use MemTest just for memory.

That explains why you keep rebooting with default settings.
Get a stable Vcore for your CPU Frequency, and if your temperature is still low, attempt to go higher.

And make sure you stress test on both Cores, do a CTRL+ALT+DEL and go to Task Manager, Performance Tab, check if your CPU is running on 100% load.

nah it doesnt work on fsb / mch +0.1v / +0.1v... now i trying +0.2v +0.2v it seems to work better my vcore right now is 1.4350v is alot for this system i guess so but lets test it!..
