Bump vcore, temps go... down??

So my i7 920 @4.2ghz machine crashed sometime yesterday, came in and it was stuck @ the bios angry at life...

decided to up the vcore a bit from 3.25 to 3.5 to see if I could get it stable...

@ 3.25v the CPU was running in the upper 70*C region...

after upping the voltage its now running in the upper 60*C touching 70*C every now and then...

does that seem odd to anyone besides myself?
 
what seems odd is your using 3.5v on a cpu with a voltage limit of 1.5v. lol

im guessing you ment 1.325v to 1.35v?

it does seem odd but at the same time the bios could of been compensating for the stability by pumping a ton of voltage into it causing the temps to go up. but thats just a guess.
 
dude its NUCLEAR

what I meant was 1.325 to 1.35

working on another project thats using ~3v thats unrelated to computers... apparently thinking about it too much lol
 
if you're freezing at the BIOS level that means your voltage is way to high.

As for the temperature issue I don't think you're getting correct readings. It does seem weird that by upping the voltage you're getting lower temperatures. Perhaps you were starving the chip before for voltage.
 
Sounds more like the motherboard may have been in auto mode. Auto will usually give it alot more voltage then it really needs.
 
no no, was not in auto

nor was it crashed at the bios the machine crashed and was stuck at the bios (you know, a press F1 message)

I am watching it now before I leave and it seems happy... dunno
 
do you have vcore droop disabled? It will be called different things in different BIOS, but Intel spec calls for drops in vcore under load, and I wouldn't be surprised if that's screwing with your readings.
 
no idea, don't know if this moterboard has a setting for that... don't remember seeing one
 
its called load line calibration in the bios and it's probably there.

oh ya good point. I remember disabling that mofo cause it screwed up my overclocks. If he just bumped the voltage without changing anything else though this wouldn't be the cause.
 
I suggest trying to disable load line calibtarion anyway.
 
Mobo's have crazy correlations between different settings and what actually happens, odd bclks more stable than even ect. 0.025V is a tiny amount, just accept it and move on.
 
the load line calibration all depends on the board. some it works correctly and some it's so far off its not even funny.
