Quick 4770k Question

post #1 of 9
Thread Starter 
Hello all,

I have a question regarding the 4770k. Ive had it for about a year or so, i got it up to 4.7ghz @ 1.28V or so stable but i decided to drop to 4.3 @ 1.23 a couple of months ago since i don't game much on it anymore. Today i decided i wanted to keep the cpu low voltage to save it's life lol. Right now im at 1.13V @ 4.0ghz and ive tested Prime95 for about an hour and it's stable with the max core @ 77C with my fans on silent, about 800RPM each. I am running the h220 water cooler and want to know how do people get their 4770ks idling around 25-28C? I idle around 34C even with 1.13V, is my chip bad at idle? I tried running my PC on Balanced mode but it made no difference. I have a Fractal R4, could it be air flow? Any tips would help, thanks.

My 4670k actually idles at ~23C, and that's on a Hyper 212+ with old TIM.

Hell, I even have it overclocked, with speedstep disabled and forced manual/constant core voltage.



The secret is C-States... go into the BIOS, enable all the C-States (including C7/C7s), and your cores will literally turn themself off when they aren't doing anything, but instantly turn on when they need to.

Notice how Vcore (the actual voltage) is insanely low, even though VID (the target voltage) is fairly high.

EDIT: Also, make sure the minimun CPU state in Windows is 0%, and get rid of any background programs that don't need to run all the time.

Hey, thanks for the reply. I enabled the settings you mentioned but my Vcore is at a steady 1.13 still. My temps are 27C average now tho which is good, but how can i make my Vcore drop when i'm not doing heavy tasks like your computer. Thanks

Hey, after a few tests, normal youtube streaming on 1080p and such, i noticed my Vcore1-3 went to my normal 1.13V and my cores went to 4ghz. So that means it's good right? Also what is VCCIN it's at 1.6V and VCOREREFIN is at 1.9V. And my VID doesn't drop from 1.13, but that's something you also said would happen.

What program are you using to get VCore? It might be getting VID instead, I recommend HWInfo64.

What's your CPU usage % at idle?


This is a picture of the C-State menu in my BIOS (you should leave EIST enabled). AFAIK, I didn't change any other power-saving settings, but your BIOS/motherboard might have some different defaults than mine.

Yes everything looks like that on mine except the EIST one, mine is enabled, should i disable?

Ah, didn't see that post.

VCore is dropping to 0V, which is good. I think those other voltages are the CPU's "supply" voltages from the motherboard, you shouldn't worry about them.


Your UnCore isn't slowing down though, and you have it OC'd. It should slow down/reduce temps if you use adaptive or offset voltage...

BTW, I said I use manual voltage with EIST disabled, but that's just for personal performance reasons (in some programs I run, the processor won't maintain maximum clocks with SpeedStep turned on, and manual voltage is better for AVX2). If you're going for low temps/longevity, use adaptive or offset voltage and leave EIST on.


EDIT: also, 22C is about 72F. Ambient temps in my desktop's room are below 70F, so your idle temps will be higher if your room is warm.

Appreciate the help man, thanks a lot. Makes me understand more
