I'm afraid to delid if I get mine, but it does help temps a lot. How was stock temps?
Has anyone had any USB 3.0 sleep problems? And I can't remember was it a CPU or MB issue?
Temps at stock weren't too bad, which is probably why Intel doesn't give a damn about using terrible paste in their CPUs. Temperatures are pretty much the exact same as IBs, maybe a little higher with the built-in voltage regulation. As far as delidding goes, let's just say my 3770K came out okay and I f**ked up the latest gen one. Word of advice: I would not do it unless you have a disposable $349 on hand to throw away. The extra few hundred MHz really aren't worth losing your warranty, resale value and the humiliation of destroying your not even a half day old processor. If the nicks in the PCB didn't kill it, the possibility of your die cracking by bending the PCB too much will. If done right, however, you may be lucky like my 3770K that now does 4.6GHz with ease in the 1.3v range, when it had the same temps at 4.3GHz/1.18v. I probably still need to get Liquid Pro for it as I have no idea how long this MX-4 will last before degrading under the IHS, and replacing it can be a b**** as the IHS has to be lined up properly or your CPU will instantly overheat.
For those wondering about the whole integrated voltage regulation deal, Intel obviously added that in their chips. If you're wondering why your motherboard still has MOSFETs, chokes and other junk, it's because the board feeds the CPU a single main voltage (user configurable from 1.2-2.3v and then the processor further regulates it from there. Before stupidly destroying my chip, I did play with that a bit and noticed that a voltage under around 1.5v will not POST, and chip package wattage seems to decrease when the voltage is raised. At 1.5v under load it was around ~100w and at around 2.1v it was about 75w. Stock appeared to be 1.8 or 1.9v.
Since some of you may be wondering what will happen now with my Haswell rig, I hope to get a replacement chip soon and I will certainly not be delidding any more chips until they have lost their value. Stupidity and accidents happen, but I could have easily lost the money elsewhere e.g. a water cooling leak killing half my stuff, speeding ticket, etc. and I will come back from this with the experience I had gained today. But for now, at least I have a slightly faster and cooler 3770K that I can still enjoy for the meantime. Lesson learned.
set 1.150, 39 multi for ring, THEN clock up CPU.
