well thnx to you guys i managed to get my vcore up to 2.05V :)!, i know that i'm already pushing it, but i'm just curious what the max vcore for my cpu is, without "really" riscing frying it??
(my cpu: cellie II 633MHz cB0 SL3VS standard vcore=1.65V.)

my current cooler is still a gorb atm, so i wont change the vcore for now, but i have an akasa silver mountain waiting, which i will install as soon as i get rid of (read: replace :p) the friggin condensator (<--is this an english word?), which is to close to my socket to install the damn cooler... LOL.

i've seen ppl go upto 2.3V (in cpu db) with this cpu, but they where using watercooling so i guess i shouldn't try this?

btw my bios lets me chose between the following settings:
2.05V, 2.10V, 2.20V, 2.30V and 2.40V.

thnx :D

2.30V?

No!

2.05V?

I'd say you're already past where I'd push it.

My Celeron 600 cB0 can take 2.05, but at 2.10 won't boot.

2.00 gambling a little
2.05 gambling
2.10 really gambling and shortening the life of your CPU but hey if it last two years then who cares you may have something much better by then.
2.15 beyond gambling
2.20 beyond sanity even with the best cooling.

I have had my p3 700 all the way to 2.3v burning in. and even 2.4v. Air cooling. I went that high in hopes of fixing the bad HS mod that chipped the core a bit(it would no longer do 133fsb).

Suffice to say I kept my eyes on temps. They werent that bad

This site here (http://www.heatsink-guide.com/power.htm) will give you heat specs and max core voltages for just about every x86 proc made the last several years. It shows your celery as having an absolute max core voltage as 2.1v. This site will also help you figure your heat load on your o/c'ed proc too.

MY Celeron 800 (cDo, 1.75V default Vcore) is on a Tekram slocket with voltage adjustment jumpers. Just after I replaced the retail Intel HSF with a GlobalWin FOP68 a couple of months ago, I increased the voltage to 2,2 V. It seemed unstable from 1152 MHz and on. Managed to boot it at 1240 MHz (highest possible FSB @ 155 MHz), but it wouldn't load any of the OS'es...
I went down to 2,1 V and 1136 MHz and kept it there for a while, attempting to burn it in, because it wasn't 100 % stable.
Some weeks ago, I read that the absolute max voltage of a Coppermine is 2,13 V. I reduced the Vcore further, to 2,0 V and 1108 MHz. This is my current voltage/frequency.

Once (when I ran the processor on 2,1 V) I noticed that the computer refused to boot. Tried starting at "default", 1066 MHz - still no boot. Had to move the FSB divider jumper back to 90-124 MHz and run it at 800 MHz. It booted fine, but Win98 was repeatedly backing up/restoring the registry files every time I started it up. Win2K was fine. Later, I put the FSB divider jumper back to 124-155 MHz and booted @ 1066 MHz. Everything was fine.
(Wonder if this was a result of the processor running at a too high voltage, 2,2 V, for a while ...?)

thnx for all your replies :)!

so i guess my max is 2.1v, so i won't push it any higher then this,
btw haven't had any trouble booting at 2.05v, it will even boot up into windows at 1045mhz :p...
