Now in windows went the power options and set the cpu min to be 88% and the max left at 100. Temps are down to 26C at idle and I gained an extra 100mhz with the adaptive vcore and cache and speed step on, and so far I haven't seen the cpu drop below 3.2Ghz.

This seems pretty awesome IMO. I'm gonna try and push for 4.6 and see how it goes.

Watch the voltage - some boards don't respect the max voltage setting in adaptive and will blow crazy high voltages through the chip.

Noted. Will keep an eye on it.

1.38v adaptive is dangerous it can just flash into the upper 1.5 range; there's no room for "hey does this load increase my vcore" type testing. If possible just don't use it at all. If somebody said "I accidentally killed my 4770k, guess how" then i would put most of my money onto having ~1.3-1.4vcore on adaptive mode. Very very dodgy stuff.

a friend of mine OC'd his 4770k and thought he was stable at a certain frequency with a certain voltage. But he did all his testing with half his cores parked (rofl). Is he going to run into potential stability issues now that he's unparked the cores?

Cores will unpark under multithreaded stress, or at least they are supposed to.. Performance stuff with parking/unparking is often down to them not unparking super easily, but that's in a situation like playing bf4, not really like hitting cinebench or prime. TBH 4770k at any overclock has like 5 watt idle anyway so there's little reason for a feature that can hurt performance or be annoying

I have different settings for ht stable vs non-ht stable, so if he's testing 4c/4t somehow without the cores unparking, maybe slight tweaks needed. I don't know what kind of multithreaded stability test would not unpark cores, though o.0

ahh makes sense. I had him using x264 so, as you said, the parked cores probably got unparked. I've got him running x264 again tonight to check for stability. Ill let everyone know if he comes up with any instability as a result of this change.

If he had parked cores, he'd be scoring like an i5 on x264 and cinebench. I've seen parked cores be ignored with lower CPU loads though (like 60% across four cores on x264 live encode) at times where it adversely affected performance

I bought a "EKWB - EK-Supremacy PreciseMount Add-on Naked Ivy" should I use Coolaboratory Ultra or another Tim on the naked die? (MX-4 or Gelid CG)

CLU will give better temps, but be aware...it a pain in the rear to get off the block. I saw 3-4c better with Ultra over Gelid with direct die.

It depends on the seller honestly, I have sold a few delid chips on ebay that performed really well and didnt have crazy voltages.
