What is the maximum safe voltage? I've heard different opinions on this and I'm a little concerned as my overclock in sig is using 1.4v full load, 1.38v idle, is the full load volts too much?

Thanks guys, tbh I'm not the brightest spark when it comes to overclocking, in fact my cpu was part of a pre overclocked bundle from ocuk, I got it at 4.6ghz and all I did after fitting a new cooler is increase the multiplier from 46 to 48 and that was it, that's all the cpu overclocking experience I have.

I noticed the vcore had increased from 1.38v at full load to 1.4v so I'm assuming there is an auto setting in the bios for the vcore and that it has increased itself after my tampering with the clock speed. Do you think I could set the vcore manually and lower the voltage or would my overclock need that bit of extra juice. Surveyor has kindly posted the voltage recommendations and the upper limit is a little higher than what I have so not so concerned now but as everyone says, lower is better.

My temps at the setting in sig is low 30'sc idle and maxes high 60's after a couple of hours under prime.

You get different opinions because there is nothing concrete even OCUK's figures are contradictory, they list 1.35V-1.38V as max for 2600K/2700K but 1.42 for 2500K, whatever the magic figure is those CPU's should be no different.

You just have to weigh up the risk and how long you intend to keep it and then cross your fingers. :p

Ummm, interesting, it would appear there is no absolute certainty on max volts, indeed I,ll keep my fingers and legs crossed, have tried crossing my eyes but it's like playing a game in 3D without the goggles lol.
Wonder if ocuk would like to comment on the three different max volts they have recommended?
Thanks again guys

am running @ 4.9=1.42v 24/7 (well almost)full load and temps are well within the limit
did a 12hr straight bf3 game the other night with no problems untill battlelog did maintance lost all my points **** happens.

at 4.8 i would off throught you should be around 1.38v.
i found that with mine if i need to jump up say 4.8 to 4.9 i had to increase the vcore by 2v.i ran at [email protected] that is what i needed to be prime stable for 5.1 24/7

just a idea

Yep, bios vcore is set to 1.38v manual, and cpuz reports this too with the 4.8Ghz, it's just that as soon as i put a load on, cpuz shows vcore at 1.4v. I have also clocked to 4.9ghz with no rise in vcore, still at 1.4v in cpuz but set at 1.38v in the bios, 4 hours prime and stable as a ****** max temps late 60's.

So, how does my computer increase the vcore from 1.38v in the bios to 1.4v when it's loaded?
Just curious, are you using as an exhaust or intake with your cooler?

Thankyou nickeverett, most helpful and has clarified load line calibration, I think I on the ultra high setting so will try it on high and see what happens. Thanks for those links.
 
Ok guys, llc was at extreme so changed it to ultra high, been running prime for half hour and vcore in cpuz now reads 1.376 then 1.384, it just keeps going between these two figures, temps are good too, max 60,66,68,66. This is all on the 4.8ghz overclock and vcore set to 1.38v in the bios. Is this okay?

Will leave prime running for a couple of hours or so.

Mine 5.0GHz at 1.38v for 35 hours prime stable as max temp hoovered around 67-69C with silver arrow with dual fans of 140mm in my antec 1200 case

Oh man, that's brilliant, :eek: wouldn't mind that case myself, if you don't mind me asking, do you get those temps during summer months?
Just noticed you're using cpuz version 1.60 I'm on 1.59, time for upgrade me thinks.
