2700k Voltage vs Temp

[zXTheRipperXz]

Hi guys

I'm new to overclocking and have a few questions regarding safe temps/voltage. Every place I look has different values for safe temperatures and voltage. For the 2700k, Overclockers suggest no more than 1.425v and max temps below 70c.

Am I right in thinking that voltage is pretty much irrelevant, as long as you stay within safe temps; but higher voltage = higher temps? For example, if a 2700k processor was in an air cooled system and 1.4v took the max temp at load over 70c, then that would be bad, but if you put the same chip in a liquid cooled system, with the same voltage, and the max temp at load was only 60, then that would be ok?

I have a 2700k, liquid cooled, in a Asus Maximus Gene-Z mobo.
I can overclock to 4.8GHz without crashing at max load in IntlelBurnTest on max with 8 threads. CPU voltage is at 1.39 and max temps hitting between 60c and 69c. If i lower the CPU voltage I get BSOD in IBT.
I can't overclock to 4.9 without exceeding safe temps, temps get up to 70c - 75c.

Seeing what some people are acheiving with 2700k's on air cooled systems at safe temps & voltage (4.8GHz+), does this mean that I've just got a less than average chip considering my liquid cooling?

Thanks!

is you liquid cooling set out right and do you have air trapped in the system anywhere, like in the cpu block or rad as that will put the temp up a lot what are you idel temps

is it a custom water loop?

How can I tell if there's air trapped? As I said, I'm new to all of this.
Cooling pipes aren't transparrent either, however I can see in the resevoir and there aren't any large air pockets.
There are 1 or 2 very small air bubbles.
I think the cooling kit is an all-in-one kit. The site I ordered the system from had a selecttion of kits. I got their advanced watercooling large kit with 360m radiator and 750res pump/resevoir, rosa CPU block, high CFM fans and large tubing. Only has the CPU in the loop. Idle temps are between 25c and 30c.
Do you think temps are high for liquid cooled then?

is your cpu retail, mine is and dosent oc well like the oem

Think it's retail. Why would OEM be different?
Do retail versions use crap heatsinks or something?

My 2700K under an H50 ran at 81*C during IBT for about three seconds when I first installed it. Knew this wasn't right so stripped it down and redid the TIM and now its down to 60*C under load. Manufacturers are renowned for over doing the TIM, indeed mine had about 2mm gauge of TIM on the heatsink!!
Suggest the first thing you do is redo the TIM. Plenty of info on the net for instructions to do this if you look. PITA but well worth doing.

ocuk and intel say keep temps below 70c. has for voltage intel say 1.35v max, ocuk say 1.425v max.

personly i keep mine below 70c and below 1.35v.

4.6ghz to 4.8ghz isn't much noticeable differece

i agree with you, but i think i may re do my tim as i think that is why my wc loop isnt keeping my cpu as cool as i would like

job for saturday me thinks.

It depends on what they consider being stable. I can run at 4.8ghz @ 1.36v and not have any issues in gaming or general use, but then get errors after 9 runs of IBT at max. I think given enough time IBT will give errors for any overclock, nothing is 100% stable. I decided that 4.6ghz is stable enough for my 2700K as it passed 25 runs of IBT at max, a load that would probably never occur under real usage scenarios.

Agree same here! 4.0ghz to 4.4ghz not much the difference! 4.5ghz to 4.8ghz not much the different! Mine is stay below 1.35v and below 70C.
