Does hyperthreading affect overclock stability?

Interesting, I'll give that a shot.
I'm not sure if its AIDA64 or the UD4.. but my voltages are very inconsistent.. for instance in the photo above, I was actually running 1.38v with LLC level 6 which give me an idle voltage of 1.416 and that dropped to 1.404v during load.
Now if I bump voltage up to say 1.39v, with the same LLC level.. I may see 1.416 at idle, and 1.428v at load?

Right, I would expect it to idle at 1.416v and drop to 1.404v at load which is almost perfect to me.. but for me to bump voltage up a bit then have it loading at a higher volt than at idle?

Try a real cpu test like LinX or IBT and post a screen shot please
Either way, NICE CHIP!
I'll do that when I can unglue myself from Battlefield3.
It has done 25 passes in LinX already.

It might get worse. Try to run a few light threaded applications and monitor how much voltage it shoots up to.

Did that.. never goes past 1.440v during use of sony vegas 10 or adobe lightroom.

Yup! That confirmmed my finding on this POST.
This voltage spikes due to various level of LLC used.
LLC is a must have feature and I do use on all previous generations until SandyBridge came along with its new Multi-Level LLC.
Why lower load voltage is lower when using Prime or under heavy load?
Under heavy load all cores were used....light load...IMO it has to do with Turbo or power savings feature.
I can't tell if this is good or bad until someone has proper equipments for analysis.
You can lower to level 5 LLC to put curb on that spike...but must raise vcore for stability of current state.
For SandBridge, I like to use offset voltage mode...without LLC.
