O/C celeron 633 to 950.

[BlackRobe]

My celery 633 is @ 791 (83 FSB) stock HSF and 1.65v.
I was pretty confident it will go to 950 (100 FSB) because if i up the voltage to 1.7 it will post and if i up it to 1.75 it will get to windows screen (then freezes)
So i figured i needed a new HSF (FOP-38) to acheive this speed. So i rang my local retailer to order the FOP-38 and Arctic silver and he told me (to my surprise) that he didn't think heat was my problem (because celeron's stayed relatively cool) and it probably had more to do with the L2 cache. He said getting a FOP-38 would be overkill.
Now as you can imagined i was very dissapointed with this as i thought i had a good chip on my hands (being able to post at 1.7v@ 950 with stock HSF and windows screen @ 1.75v)
Can anyone tell me this guy knows not what he says, with my cel 333@416 i was stuck with 83 and this time i really want 100, as i said before it does 791 with stock HSF and the 1.65v, so i thought it could do 950 easy.
What do you guys think, is this guy of his tree?

Any help much appreciated. Cheers.

BTW.....
Abit BH6- no CPU temp monitor
CPU fan rpm = approx 4355, chipset = 31deg / 87.8f

Not having a way to moitor your cpu temps when ocing is not very good.
Best bet is to go to the main page and look in the cpu database and see what others are getting out of that cpu.

I think this guy is off his rocker, Get the HSF and the AS. You may need 1.8v or even 1.95 to get it stable. My cele 633 will run at 950Mhz to 1102Mhz at 1.95v depending on what kind of cooling I am using...

With a good HSF you can safely run the chip at 1.95v. And I am sure that you will get at least 950 if not a Gig...

Besides, if I am wrong, the new HSF can only help. :)

yeah...thanks
thought as much myself, and you guys think the fop 38 is th way to go, it's going to be hanging of the side of a slotket:)

Hi guys,
My C633@950 stable at Vcore 2.05.

Do you think it's too high?
I use cC0, BX w/ thermoengine + delta fan no lapping.
Room temp 33c.

hmmm 1.65 default v must be CBO? i had one it took a lot of work and 1.85-1.9v to be stable at 100fsb. as far as hsf, i would recommend an alpha w/ delta i put a fop38 in a box once and was not so impressed

What did you have to do ?

if you have sandra it will tell you the stepping under cpu info. what i did to coax that baby up was burn it in! but it took some work... i upped the voltage to about 1.8 (as high as temps would allow) and burned in for awhile, then was able to get it to 1.9v (tops for cpu+board combo) and burned in a few more days. after first burn would run around 90fsb@1.8v and after second burn in would post up to 107 and ran at 104fsb@1.9v. if i had a slocket i could have maybe got her higher...if yours posts at 100 already you shouldn't have such a rough time

cant hot 100 eh?
and your ram is what? plz dont say PC-66 cas 3

if you hvae PC-66 cas 2 even, set the ram to the slowest speeds possible while you are testing for a stable CPU

Why would you think my RAM to be pc-66?
I'd think from the facts presented it's fair to say i need a new HSF.
If my ram was 66mhz i wouldn't bother asking this question....would you???
My RAM is PC-100 cas3 (stable at 2 , but yes...set to 3 when testing)

Yeah logos, it is cBO, does this just mean its the revision before cCO? therefore.......?
Thanks
