celeron 700 overclocking

[mgmanten]

i'm having problems overclocking my celeron 700.
it's now running at 877 mhz. fsb 83 voltage 1.8
sometimes windows just close (especially half-life)

system:
ASUS CUBX-E ata100 controller onboard
2x64mb 100
1x128mb 133
Geforce2 mx
sblive!
trust modem
13.5 gig maxtor
philips 48x cdrom

can somebody please help me out, also i'm very curious if i can get higher than 877 without the whole computer shutting down?!

[Carmine_Paterno]

hmmm...is your chip cC0 stepping or cB0? If you don't know you can use sisoft sandra 2001 in the cpu/bios menu to help you. If it is Cb0 you are very lucky, i know almost all people with cB0 Celeron II 700's they can only get to 840. My cC0 hitts 1015 @ 2.2v, but no games. @ 966 i can run games and it is very stable @ 2.1v. Try upping the voltage more. If you have a P3V4X/other slot 1 mobo you could probably hitt more becuase of the voltage adjustments on the slotkeys.

GOOD LUCK!!! If you need anymore help, please email me, bmxbyker14@hotmail.com

my cbo does 875 but i gotta back off to CAS3 to do it. so i rather stay at 788 CAS2 latency
default voltage.

I am stable @ 1.65v @ 903 (default voltage is 1.7v cC0) and runs just dandy. Nothing like a P3 Processor tho! My p3 450 @ 600 (133fsb) moves! I will mess around with celerons more, but the p3 is my new chip.

[wild_andy_c]

Go a tad more than 1.80v - try upto around 1.90v. That is a sure fire way to see if the chip will go a little further.

Be careful if you don't have a very good cooler though. And don't go upping the voltage as high as some folks do. 2.1 volts is the maximum peak voltage that the cB0 and cC0 should take, the thermal dynamics of the cC0 being a little better. A small split second surge in voltage could kill a chip, and little do some people realize that when a chip dies, it has a knack of taking out the board with it half of the time.

Don't go upping your voltage too far is the crux of it. If anyone tells you to put the voltage past 1.95v - ignore them. Perhaps they will get an overclock they like for a short while - but the chip life will decrease big time.

[Carmine_Paterno]

LoL aight andy i get the point

[mgmanten]

what's the difference between cBO and cCO?

[TheGimp]

Just to throw one more into the mix, I have a Celeron 700 - cC0 "Engineering Sample", and there may or may not be something to the hype about "ES" chips, but I am having no trouble running 1050 @ 1.80V with temps of 34C to 37C under 100% load. The other side of the hype is the multiplier is definately LOCKED. One thing is for sure, I lucked out, as the performance of this chip is the exception not the rule.

The cB0 and cC0 referred to is Intel's version numbering system. the cB0 is an earlier version of the 700 than the cC0. If I'm not mistaken the cB0 defaults to 1.60 Core Voltage, while the cC0 defaults to 1.70, and it is said the cC0 is more overclockable than the earlier version.

sandra reports cBo 1.5-1.7v. runs at 1.65 like a P3

I Have a Cel 2 700 runing stabel at 1050 on a via Fic ka11 M/B
It's Cc0 Stepping i had to crank the voltage to 2.1 firist to get it to run then i started to decrease the Voltage and now it runing super stable at 1.9 V it posts at a weird spead on my other board Gigabyte BX 2000 it shows 1034 mhz but works also perfect i flashed bios on both boards to latest versions available
But whatever i try i can't get it to even post at 112.5 bus

Post some pics of this, i would like to see it, I am sorry to say this, but i highly doubt it as i can only run my Celeorn II 700 @ 966 stable @ 2.2v. What cooling are you using? I also have a cC0 stepping. I am going to wire my vid pins so i can select up to 2.6v and get this baby to 1050.

Some chips are better for overclocking than others........

2.6v ? That's insanity. You'll have a C II keychain in short order........

I'm not in the habit of entertaining challenges, but here goes:

[Mr B]

You got a really good one, there. Best part about it is the 1.8 vcore. What are you using for a hsf? Somehow, I think the answer is going to be "Alpha".

Rockin' chip! Well done.

Mr B

[TheGimp]

You are indeed correct, I have one of those Alpha's with the copper insert, (PAL 3065?), but it doesn't have the screamer fan on it just the normal 60x60x25.

As I have stated in other posts, I know this chip is the exception, not ordinary in any respect as it is an "Engineering Sample", and I would have left it alone had another member not expressed his reluctance to accept my information as valid. The sad part is, mine will still be running 1050 long after his goes up in smoke from high core voltage.

[Mr B]

Gimp,

The reference there is well understood here. Unfortunately, it will not be "there", I think, without that wisp of blue smoke actually happening.

I've got a PEP66T on my Celeron now....best thing I could have done for it. Now I'm just waiting to do the same for my P/// 600E, and try it out. I did some testing with it running the intel hsf, and got 852 MHz (142 FSB) @ 1.81v on my Soyo 6BA+III (max vcore possible), and it posted at 936 MHz (156 FSB) @ 1.9v on my Asus P3C2000, but the temps shot up quick and I shut it down. I'm gonna swap back in the Asus for the Soyo, format my old 1GB hdd and see what this chip will do with good cooling.

My P3125 is sitting one half mile up the street, at the post office, as I type. (Waaaaa, I wannn it noowww!)

*sigh* First thing in the morning. Gonna make for a long day at work, staring at the shipping box......

I'll be sooo happy w/ 950 MHz, if it will get there. I don't realistically see 166 FSB / 1 GHz, but boy would I like to.

Mr B

[TheGimp]

Understood, somethings just have to be experienced. In fact I hope my assumptions are all wrong.

Advised otherwise on MULTIPLE occaisions, but pushes it higher anyways.

It'd be a shame to see a decent chip so needlessly fried, but it's not my call. I can but only advise, not govern.

[Carmine_Paterno]

I am gonna sell my celeron II 700 and by april i should have my P3 700e.....YEA!!! Then i will/won't show you all how to o/c. LoL i hope i get a good one! My celeron II 700 cC0 is running @ 1.75v @ 914. Stable.

That's why I can't see getting a celeron..sure they're cheap, but you get what you pay for...and to get a good gig...you are only running the bus at barely over 100...to me yo ain't overclocking till you have your memory, and agp maxed out, and you can't do that with a cellie, with the exception of the 800, which I think is a overclocked 600...besides I hate castrated cpu's.
I think the celeron will die when the new P4's and PIII's come out in q3, or q4

[Mr B]

Celeron 800E (100 FSB) = Celeron 533a (66 FSB)

Funny, I thought intel locked the multi to keep people from re-badging chips and selling them.........

Mr B

[DocClock aka MadClocker]

Yea, but who's to stop them from doing it themselves?
They did it with the PII 300, or 350, I can't remember which, they had such a good yeild, and had so much demand for 300/350's that they remarked PII 450's as PII300"s and ran them on a 66mhz bus, where the 450 ran on a 100mhz bus...which is why that particular model of PII is still expencive compared to other PII's rated at the same mhz, 'cause it was a garanteed overclock to 450..I reckon it must have been the 300...'cause 66x4.5=300, and of course 4.5x100=450
People soon caught on to that S-spec, and the price almost doubled on it.
A little history for Ya...or at least my version of it

can anyone help me with this question ?
why does my computer not booting at all at 100.3 fsb?
it doesn't even show the bios... it just goes on standby mode !

CUBX-E mobo

other specs are in the first mail of this forum;
thanks!

[Rocky55]

i use to overclock that chip. It doesnt overclock worth a sh#$. I had to go out and buy a 667 to get that board to overclock right. I had my 667 up to 1050 and the 700 up to like maybe 900 if i remember right.

Try setting the vcore higher....1.9v should get you a bit further. I wouldn't go much further than that, though.
