overclocking vid question 2600k sandy bridge

mr griffin · 23 Mar 2011 at 12:56

Hi,

I got my 2600k up and running at 4.8ghz with 1.34v in bios and cpuz and hardware monitor both report about 1.35v under load the thing that I dont understand is that in core temp my vid is showing from anywhere from 1.35 -1.5v and is changing all the time even at idle. Is this a problem or anything to worry about or is it just going mental don't really want to kill anyhing

Aslo temps wise im getting 34 degrees idle and about 70 running prime 95 small fft's is this within the safe limit of the cpu?

cheers

Don't rely on coretemp, and the temps are fine fine. The max limit is ~90C

thanks for the reply. had to up the volts a little to 1.36-7 for stable 4.8ghz temps are still about the same. These chips fine to 90 degrees that just seems so hot!!!

90 sounds a bit high to me. Not got my sandy bridge up and running yet but i7 920 safe temps are lower than that

been on Google and no straight answer but i think its 72.6 like the 920 etc

I remember reading the Intel datasheet which said the maximum safe operating temperature was 98C

I would like to see that. Will be the only cpu that can run that hot

Not going to look through the whole datasheet but:

Like i said 72.6 says it there.

I think there is a massive misconception that the 2600's are cool running chips. I know several people on high end water which load in the 60's while running Lynx. Assuming your on air those temps seem to be pretty reasonable to me.

mr griffin · 24 Mar 2011 at 14:17

linx gets it to just under 70 degrees while prime 95 small fft's gets it to just over 70 degrees. I am on water cooling but I'm using an old d-tek fusion v2 cpu block and only a crappy swiftech 240 rad.
