cpu over voltage error!

[MegaMind]

Hey guys, i'm trying on extreme overclocking with my 2500k. My rig specs are in my signature.

I can get a stable OC at 52*104 = 5408MHz @1.555v. When i set 1.56v, i get "cpu over voltage error! Press F1 to enter bios".

The max. temp. in Superpi 32M is 42'C, the following is my benching setup.

As the temps are low i wish to go further, is it safe for my CPU n mobo?

Going over 1.5V with SB isn't considered to be safe.
You should stop your 'extreme overclocking' & be happy with normal overclocking. 1.45-1.48V (max) is considered to be highest safe point for SB processors.

Ya i have to control myself

If you burn your CPU by going over 1.5V Intel won't replace your CPU AFAIK.

Don't tell them that it was overclocked.

How is it that high OC is achieved by LN2 safely?

Overclocking in 20C & −196C have that difference.
Oh, I got your question now. In Extreme-Z board there is 1 switch, located beside DIMM slots, below temperature LEDs, just over onboard on/off, reset switch, which used to turn ON/OFF LN2 mode. That's how in LN2 mode people can go over 1.5V.

@ico: We don't need to tell them, they will understand. Most of them are there dealing with CPUs for years.

So no other mobo can be used for LN2 cooling?

I've no idea about other boards. They might have same feature.

^^No not much, that LN2 switch is provided to fix the cold boot bug..

 

[sumonpathak]

any board can do ln2..AFAIK that switch is not related to some magical vcore settings.

That should stop the over-voltage error. But about the scenario described by MegaMind, well, I think he can't go above 1.5V by any means.

^^he shouldn't...but we cant really stop em here....


lets try anyway...
STOP or the kitten gets it...

Sorry guys i have been too hard on my cpu.. I want it to go on for years so i'm stopping my overclock..
