Hi, I recently brought new motherboard and CPU a 4970K 4.0GHz. I would like to ask you guys is CPU voltage at 1.276 at stock with turbo boost enabled correct?

Sometimes I see the voltage go to 1.286 but for like a second.

I have left my Asus maximus vii ranger motherboard settings are all auto.

I also have Noctua D15 cooler and was wondering if the temps i get are good or bad?

While running games it about mid 50s.

I would like if someone can help me out in getting lower temps and maybe if its possible to run the CPU at a lower voltage at stock clock speed with turbo boost enabled.

are those 4.4Ghz done by you or stock? because on stock, only core 1 and 2 are boosted to those values. 3 and 4 go only to 4.0 if i recall correctly.

if you haven't still done it, you should go to the bios and lower your voltage manually. The stock voltage that the mobos nowadays input on the CPUs are almost always too damn high!

i can't recall the voltage i had for 4.4GHz, but for you to get a grasp, the OC of my 4790k is 4.7GHz on ALL cores, at 1.25V.... (check my signature)

so yeah, that voltage is completely off the scale for that clock speed. try to change Vcore manually to 1.15 and see what you get with some stress testing. If you crash go up until you get it stable, if stable go down.

Dont worry on getting too many BSOD while testing. Top thing you can get is some corrupt files (like me, got some files of CSGO going berserk lol), but i'm guessing you dont have important stuff on your PC since you built it recently.

Also, download and install HWInfo, best software for monitoring.

I would have to disagree. I usually get those temps at 4.6 GHz, and while playing, not stress testing...

Also like i said, i have almost the same voltage he has, but i have the CPU at 4.7 on ALL cores, not just the first two.

Edit: oh, and i have a CM Hyper 212 Evo, not a top notch cooler.

Do you have a guide for overclocking at what your speed is set to with vCore at 1.25v?

I cant get mine stable at 4.4 unless i apply 1.2v. Also cant get 4.7 stable until 1.36v . My chip just wont do it... but my temps are below 51c innprime 95 . I also have a modded HAF X tons of phantek fans and replace stock case fans as well with lwd phanteks and removed drive bays for push pull 140mm fams inside the case...

my process:

1- disable all energy saving options on bios and put all 4 cores on a 44 multiplier. Leave the Vcore alone for now. Stress test (if u use prime95, use previous version, not latest please.). This way, CPU-Z or HWInfo will give you the REAL Vcore. When you have C-states enabled, the value represented is the VID, not the Vcore.

2- Check results. If stable, start lowering the Vcore. I would go directly to 1.15, but its your choice. When you get a crash or BSOD, up again for last value. Do this in steps of 0,025 volts.

3- When all is stable (please do a run of some 8 hours for last stress test), enable C-states and energy saving profiles.

4- Dont forget to go to "energy options" on windows, and set the profile to balanced (or put manually the option of CPU power => min = 5%, max = 100%). I strugled with that, cause my multiplier was allway on 100% and i didnt know why :p


think im not forgeting anything... (dont forget to get HWInfo. best software).

@blasc... you are right to try to lower volts.. i like your style and you DEFINITELY no what your doing. So the OP should try to lower volts if his chip will do it , then great. You won the chip lottery
Mine would not. I lost... however they are safe temps and safe voltages......

My best suggestion (since i'm at work and am multi tasking right now, it's getting hard for me to put my thoughts into words) is for you to search "4790K underclock" or "4790K undervolt" in google.

you will get some pretty good tutorials on how to get better temps, lower voltages and still a good clock speed ;)

these chips/motherboards always come with much higher voltage than what they really need.
