No looks more like it degraded from non Stable overclocks...

If you run a non stable overclock Cpu for any long period of time it will degrade fast... Why i put some much effort in making sure i was stable..

I should say that even though I cannot IBT it without temps creeping towards 105 and me stopping it. I am at 4.8GHz and 1.368v with the 3570k. The OC seems pretty stable and happy for the past month or so I have been running it. No events in the event log, it wakes from sleep without issues, and the highest temps it sees from gaming are 64-65 degrees, and it passed an overnight prime 27.7 ~10 hours at 8 min per fft with 80% of my ram. Thats where I get my max temp from. I know it should be longer but I am not seeing problems yet to speak of and my wife uses the computer to work from home during the day, so 12 hours + is tough for me. This is again not-delidded and on air. And LOL if the computer ever started crashing or freezing while she were working and she lost a spreadsheet or something I would definitely hear it!

yes. The symptoms both chips followed (used in different manner on same "faulty" board at first) are like this:
a) sudden increase in CPU core temps at same voltage, reaching up to +10C for no apparent reason
b) shortly after vcore demand starts growing, by around 0.03v every week at higher clocks (e.g. 4.7GHz+)

chip A was used mildly at 4.6-4.7GHz daily, max clock was 4.8GHz.
chip B was used more suicidal, but still in reasonable temp range and vcore before deliding, then totally suicidal afterwards. also chip B carries a faint brownish spot (burn mark?) on terminal side since I removed it from Z77 FTW board, at first I thought it was some dirt, but it cannot be rubbed off or cleaned off.

The "faulty" MB I mentioned was the EVGA Z77 FTW which caused me lots of grief and was considered as a "bad batch", e.g. not allowing to use Integrated Graphics at above stock CPU clocks (POST code lockup 9A), even at stock CPU clocks with Integrated Graphics enabled some voltages in BIOS were messed up and out of whack, giving awful memory compatibility issues (POST code lockups 23 & 55), also having numerous bugs in BIOS (even on good batches) often resulting in BIOS corruption and a need to reflash, eventually I gave up on it and returned to manufacturer.

Ah do not buy Evga Mbs there whole MB Engineering Team quit on them and went somewhere else..

Why it took Evga so long to release a Z77 MB..

Stick with Asus And Gigabyte for peace of mind.

That seems very stable actually. I have one heck of a sturdy chip. 1.87Vcore i pumped in last night.......Shhhhhhhhh. Yes Little Franky is more than fine he's been folding all night happily. I believe I have done some pumping out of my px-3. Temps hit 61C for highs now instead of 58C. LP is on the way however!! tongue.gif

Okay I think to be fair to everyone who either wants to change the Sig or keep it the same should say so. If you wanna change it post it on here (Make it look like the actual sig not the code so we can actually see it) and then we can do some voting for it. I'd like to see everyone happy and not confused lol.

yes, I learned it the hard way ... upgraded from my old good evga 790 Ultra (was awesome for a few years) to EVGA Z68 FTW and considered it unfinished and limited in both design and BIOS support, so upgraded to latest Z77 platform (Z77 FTW) ... geeez, what a failure ... what a nightmare, never again ... Asus MB it is for me now and I feel like in heaven smile.gif

Sounds like possible pump out of TIM as well.

When your TIM pumps out and doens't work very well the heat increases and you need more voltage to get the same effect on the CPU stability because of the added electrical resistance caused by the heat.

I am seeing the term pump-out used alot. Whats the explaination on that?
