Over 2 volts too high?

[Xaeron]

I'm o/c'ing my celery 700 to 1050mhz. I got it to post and start to load windows but then it locks up. The voltage I had it at was 1.9 (default being 1.7) and I'm afraid to push it any farther fearing i'll fry the chip. The cooling that's on it now is a large aftermarket HSF. What do you all think?

Believe this is one for Mr. B.

He has a Celly 600 with over 2V pumping through it.

I would say it's ok as long as temps are kept under control. you're dipping in dangerous waters though...

Over 2v is too high I don't care what any one says, just becasue a few chips will run ok (for a while at least) at high voltages does not mean every single chip can, I would advise the maximum any one go is 1.9v unless they have a peltier, I don't think it is even a heat issue as I have know people run their chips at like 2.1v and they haven't been very warm (less than 40oC) and the chips have still died after a while. You may have a chip that will be fine at over 2v but unless you don't mind risking killing the chip I wouldn't advise finding out.

That chip has a 10.5 multiplier. To get it to even post at 1GHz is an accomplishment. At 2.0V, you are still within the max spec from Intel, but risk damaging the chip. I would consider anything over 1.90 with aircooliing to be risky. Then again...I am conservative by nature. What are your temps at the highest stable speed you can run with this HSF?

[Phil]

voltage can vary greatly, I have only ever seen a 0.04v variance in my voltage but with power surges and if the cpu is in an idle state then you could quite easily have the voltage going over the maximum for the chip when you put the voltage high up in the 2v area

[Xaeron]

oh well forget it... my board will only let me goto 1.9 because of "saftey" issues i'm stuck at 700 i guess 874 is nice but i have to turn off dma and then my burner doesn't work it always locks up loading windows at 1050 darn darn darn

[Phil]

see if you can sell it and buy yourself a 56 or 600 from ebay

I run my Celeron II 700 @ 987 2.3v and it is just fine! Never game me a twitch. Pretty funny tho, i never ran chasis fans before, but now i did, and now on my p3 450 i can goto 617 136fsb @2.3v 3.9 i/o. Gonna see what i can do with my celeron.

Ok now about your chip, looks like it is maxed out @ 874 on your motherboard. I would buy it from you, maybe building a dual Celeron II 700 machine....interested but skeptical. How much would you want for it....i am short on money....I am only 15....cC0 i am guessing....THANX

Here I am.....

Yes, I had (past tense) the Celeron at 2.05v for a while, but have since backed off to 1.95v (see sig below).

I was pushing it for a while, but now that I'm stable at well over a gig, I felt it more important to sacrifice a few MHz of speed for safer voltages.

Running that high for extended periods of time really isn't good for the chip, in terms of life expectancy.

The only way I really notice the difference between 1020 MHz and 1053 MHz is when I run cpu benchmarks. Why kill a chip so you can run Sandra and get higher numbers. Run it there while burning in, and take a screenshot, and back down when you're stable.

Sanity is starting to prevail here. I've re-joined the "under 2v crowd". I'm learning.

Dangerous waters, they can be. Electromigration......not good for my C II.

Celeron II chips don't support SMP (multi-processor).

neither were the ppga's until some one worked out how to do it

[Dai the Flu]

Just don't do it... today my p!!! 800@1080 died... the cause? voltage was to high... the temp never crossed 28c

ps...

I just picked up a p!!! 1g and am running it at 1.13GHz at default voltage...
