i7 2600k Voltages on idle and load

post #1 of 7
Thread Starter 
I am having problems overclocking my 2600k - now I'm not an extreme or heavily experienced overclocker, but...

I can get the speeds up to 4.4 / 4.5Ghz by manually adjusting the voltages etc, that's all fine, but what bothers me is at idle and 1.6Ghz the voltage is still around ~1.30v, so it's doesn't lower it with the clock speed.

I understand there are setting to do make it do this (C1E, EIST, LLC), but they don't work on my board when set to 'Manual' for Volts (gigabyte z68x-ud3p-b3) and after a quick google this also seems disabled with other boards when setting a manual voltage (ASUS and MSI).

The only time the voltage raises and lowers with the clock speed is with voltage on AUTO. With that setting i can achieve 4.3 Ghz stable and voltages are ~1.0v on idle raising to ~1.30v on load. Seems fine...

I don't want a massive overclock, i would however like to run 24/7 at maybe 4.4 or 4.5 GHz... but i am not sure ~1.3v when idling at 1.6Ghz 95% of the time is good for the chip.

So, any advice is appreciated - e.g. what do you guys do? Do you disable Speed step, do your manual voltages decrease with the idle clock speed? etc...

Are you changing the multiplier or just messing with voltages? And I wouldnt worry about 1.3V, that should be a safe volatage. Just dont go above 1.45v.

Changing the multiplier with everything left on Auto and the best stable overclock i can get is 4.3Ghz and the volts on auto which means they rise and fall with clock speed - great. But to get a higher O/C i use manual setting for volts (never going above 1.35v) and noticed the volts never change, even at idle speed of 1.6Ghz (when intel speed step kicks in).

So i guess my question is - is this normal, and if it is, is 1.30v at only 1.6Ghz when idling 95% of the time ok?

What motherboard are you using? To attain a higher overclock more changes need to be made in other areas apart from just the vcore and multiplier

gigabyte z68x-ud3p-b3

I had to use LLC Level 6 to get my 2600K stable at 4.5 Ghz. I had to set vCore at 1.30v.
Now when it's running idle at 1.6Ghz (multiplier x 16) it's still using 1.30v ~ 1.34v - Both C1E and EIST not lowering the vCore...

I would not worry about this my board does the same (asus p8p67 pro) weather or not it runs at 1.2v or 1.4v @ idle, temps are the same around 28c

It is the current the cpu draws under load that creates the heat. 1.3v is a mild voltage increase and is very good for 4.5ghz. Most people use 1.35- 1.4v for 4.5ghz with a lower llc setting

Sorry for restarting this thread! but i really need an answer. thnx to everyone who will reply, i know it is an old topic, but i'am still using and old 2700k, and i need some help dealing with my OC. (sorry for my bad english, i am danish)

I'am new to the site, and new to OC'ing.

i recently replaced my 2600 non k, with a 2700k and with this i started OC'ing.

My OC log:

- I ran IBT on Very High for 10 runs 3 times without crashing.
- I also ran Intel extreme stress test and Aida64 for almost 3 hours without crashing.
- As of right now my system seems stable. I have been using it for games and normale work for almost a week now and i havn't had any issues. even if it should crash at some point, could it still be considered stable or should i run a 24 hour stress test to make sure ??

Idle temps: 25-32. (Realtemp)
temps while gaming withcer 3: 45-72. (MSI remote server app on Iphone) -most of the time it is around 60 +/-

my questions are;

1: Is 1.416v(Idle) and 1.376(Load) safe voltages for a 4.6 Ghz oc ?(taken from Aida64 and CPU-Z)?
2: Are 100% load temps around 78-80 degrees max safe for the 4.6 Ghz OC(During IBT, 20 min. in)?
3: Anyway to get the voltage down and still be stable?
4. Should i try testing it on Prime95(heard it could be harmful to the CPU)


Anything below current voltage seems to make IBT crash just before the 10th run(happened 2 times i a row)
always this error: CLOCK_WATCHDOG_TIMEOUT

My specs:
MSI P67a-c45
i7 2700k 4.6 - Noctua d-14 air cooling. (in denmark the temps almost never goes above 26 C. current temps are at 10 C.)
G.Skill Ripjaws 8 Gb(1600-9-9-9-24)XMP enable
Asus Strix GTX 1070 OC
Corsair CS750M 80 Plus Gold.

A big thank you to all who reply !
