now that my 4770k is not in my main PC anymore, I felt comfortable trying to push it a bit more... and I'm cooling it with a spare H80i I had around....
But oh my mine seems to be total dud... I've read maybe the first 20 pages of this thread (not goona read through 1900+ pages haha) and my 4770k must be the worst one by far... here's how bad it is..
I just put multiplier to 4.1 to start. Ran IBT standard 10 and the moment IBT starts going, the package temps hit 100 celcius and starts thermal throttling. the cooler doesn't even have time to pick up any heat... CPU package temp just jumps from ~34 idle to 100 within a second or two... The vcore voltage was set to 1.2 (with .03or 0.04 offset) to start. So I tried lowering the multiplier to 39, which equates to the stock boost clock... same thing... CPU package temp shoots straight up to 100 degrees... I've tried re-seating the cooler a couple times already with different thermal compounds, so I'm sure it's not the issue. So on 39x multiplier, I lowered vcore voltage to 1.15+ 0.03 or 0.04 offset) and it still does the same thing... I keep lowering the vcore voltage lower and lower, and still shoots straight to 100degree / starts throttling...
I thought maybe there's a setting in my Asrock Z87 Fatal1ty Killer board that boosts vcore voltage automatically, but I verified with CPU-Z and HWmonitor that vcore voltage is around 1.1~2 the brief moments I let IBT run...
The computer never crashes though... I let IBT run with CPU getting throttled a few times, just to see if the comp crashes after getting tired of the temp going crazy even with stock speed / low voltage.. never crashes... that's the weird part...
Anyone have this bad of an example??
