How easy to o/c a Celeron 600Mhz???

[HeNry2cOoL]

I consider returning my Celeron 700Mhz cC0 flipchip because i wasn't able to run it at 100Mhz FSB. And im thinking of exchanging it for a Celeron 600Mhz, so how well will it be able to run at 900Mhz at 100Mhz FSB with it's stock Intel fan/heatsink? Or should i be better off getting a Celeron 566Mhz?

The odds on getting to 100FSB increase as you decrease the cpu speed. The 566 and 600 are both good candidates, but the 566 is most likely to run 100FSB. A lot of 600's will also, but it's a crapshoot.

[HeNry2cOoL]

Well since i will be using a iWill Slocket II, i won't be able to get any FSB settings between 66Mhz to 100Mhz. It's either 66 or 100. So i gotta be sure i will be able to get to 900Mhz at 100Mhz FSB with the Celeron 600 cC0 with stock Intel fan/heatsink.

There's no guarantee that you'll get 900MHz with any coppermine core. That's the region in which they run out of steam. Some make it- some don't.

I'm not sure I understand your comment about the Iwill slotket and FSB. If you are referring to the jumper that selects between 66/100FSB- that isn't a problem. That jumper programs pin B21 as I recall, which is the method the MB uses to determine whether the DEFAULT FSB is 66 or 100. It doesn't limit the ability of the bios to change it. That's how the MB knows to run 100 for PIII's and 66 for Celerons.

The factory hsf is also a limiting factor for pushing a chip to operations near the core limits. You will probably have to bump up the Vcore to run at this speed, and the oem hsf may not be enough during heavy load.

Based on amount of Celeron chips we have tested (min. of 100 chips each), here are what we found in terms of chance (greater is better) of each type of CPU overclocked to 100MHz FSB:

C2 600 cC0 > C2 566 cB0 > C2 633 cC0 > C2 600 cB0

Unless you are planning on using some exotic cooling, don't bother with following Celery chips, regardless what stepping:

C2 667, 700

Hi Humphrey, thanks for your message,
i´have a c2 633 (sl4ny 1.7v) there is no go to get 100.
Any experience with that baby.
My board asus culs2-c
(Sorry for spelling)

best regards

So Humphrey.. you're saying that the Celeron cC0 600 has the best chance of being able to o/c with 100Mhz FSB out of all the ones u listed?

I recently recieved a Cc0 600 for christmas and I am at 900, the only advice I can give is get a GOOD heatsink/fan (i have an orb, and i'd give it a mixed review) and artic silver compound (don't settle for less on the compound, for me this made all the difference between 600 and 900!!!); btw personally I like the Cc0 600's better than the Cb0 566, but hey it's a big crap shoot anywho.

[HeNry2cOoL]

So how's your system running? Is it stable with it running at 900Mhz?

Hi Hima:

Yes, we tested some of them; the success rate we recorded for C2-633 cC0 reaching 950+MHz is about 50-55%. cC0 C2-600 is a much safer bet on reaching 100MHz FSB.

Yes, that is exactly what I am saying, from hundreds of Celeron II chips we have tested thus far.

My cc0 Celeron 600 does 100fsb at 1.7v, but it takes 1.75v to be completely stable. I've had it to 945 at 1.85v but it isn't stable in WinNT. Might be okay at 1.9v but I'v opted for the cooler 900Mhz / 1.75v.

I thought this was great 'til I got the new Duron this week which is doing 1010Mhz easy, with I think more to come.

The Celeron is cooled by a Pep66 with Delta fan. The stock hsf gave lots of trouble. I've since lapped it and put it on the Duron with good results -- running in the mid/high 40s C (a temporary measure til I get a new hsf).

I got a Celeron II 600 for christmas as well, and it works very well, 900 MHz overclock with generic heatsink/fan, on a Gigabyte GA-6VA7+, don't ask for the voltage because its one of those auto-adjusting ones. I'm also using 128MB Generic PC133 CAS3 RAM if that matters at all.

[bruce]

I've had no problems with my 600 @ 900, cool and stable!

[deam]

I've had no problems either..
I have Celeron cB0, asus p2b-f @ 100mhz fsb...perfectly stable in Quake3arena, UT, sandra soft burn in, and several other stability test programs over night...
and mine is supposed to be bad..
I've had no problems..but from what I've read, I may be lucky.

Ok.. now im kinda pissed, i just came home today from Fry's, about 30min drive away. And to find out they gave me a Celeron 600Mhz cB0!! Now what do i do?? It's kind of a pain in the ass to go back there for an exchange. I tried to overclock it at 1.7v 100Mhz FSB with no luck, no video and no post.. Guess i'll try a higher voltage. Damn Frys.... The box had a copyright dated as 2000, so i thought it was a decent and new cC0, and was packaged 9/17/00.

[HeNry2cOoL]

Dream, do u have a Celeron 600Mhz cB0?? what's your voltage setting at?? and how are you cooling it? All i have is the stock intel fan/heatsink.

[Vfrjim]

I have a 600 CC0, rock stable @1053, and will boot into windows and play in Glide mode for about 30 minutes @1108, then just crash to desktop. No lapping, no Peltier, Just a Golden Orb, radio shack grease. Running it @ 2.00v, CUSL2, with Memman Infenon PC133 memory, Win2k SP1, Dlink DFE-530TX+ NIC, SB-live Xgamer, V3-3000 pci, Adaptec 29160 SCSI. Have posted to 1152, probably would go faster if I tried:) . Your results may vary.

I've o'clocked two cC0 600's to 900 @ 1.65v which is actually .05v under the default voltage for the cC0. Rock stable on both BH6 1.0 and BE6II rev 2.0. I did slap a Gorb on to lower temps 8C to 29C at idle & 41C under full load for 5 hours. This was way too easy.
