I keep mine at 5ghz 24/7 and I don't use Speedstep. Mine idles at 5ghz and never changes. My chip also only needs 1.392v under load for 15hrs of prime blend and temps under 60c with my chiller and under 74c with my quad rad. Anyone running a Sandy will probably end up with a 22nm Ivy in a few months anyways

Not true, just requires more time. I currently have my rig stable at 5.1GHz with 1 thread, 4.9 with 2, 4.8 with 3, and 4.6 with 4 threads.
Thats pretty good on a 212+. Not a bad idea at all.

Nope. May write one if I get around to it though.

It's really as simple as setting the turbo option to per core instead of all cores.

But how to test for stability and if you're using HT? With no HT I can see by testing limited cores with Prime95. Man, you're making me curious.

That's a good question. Perhaps disabling HT and guesstimating the increase in volts with HT on? Dunno.

Even with Ht off? What's it take for volts at your overclock? More than 1.5v?

Mines been doing only 4.8GHz since two days after I got it.

4.8GHz at 1.425v. Might be able to lower the voltage but I don't have time to babysit it while I stress test lower volts. This is my homework rig.
