Is O/C on Win 2K Pro possible with Celeron 533?

Is O/C on Win 2K Pro possible with Celeron 533? What precautions should I take or anything I should look for?

Thanks,
Derek

Well.. you need to provide us with MUCH more info than that

what type motherboard do you have?? does it have ability to adjust front side bus(the intels only overclock via fsb)

you need a good heat sink and fan.. you can probably get away with a oem one that you have if you take off the gay thermal tape they have on there.. clean it good and apply thermal paste

This is what I have http://www.soyousa.com/sy7000.html

[*]66MHz FSB Socket 370 Based LPX All-in-One Mainboard
[*]Intel Socket 370 Pentium® Celeron processor 300~533 MHz
[*]Intel 82810 (Whitney) two chip AGPset

Hope this helps a bit.

Honestly.. I'm at work and dont have the time to research your mobo..

Check the manual and see if Bios or mobo(dipswitches) are there to adjust fsb

If you can adjust fsb...you should be able to get that celery to at least 700mhz.. maybe up to 900 if you are lucky but i wouldnt do that unless you really juice up your heat sink...

If you find out how to change your fsb (if it has that function) try to bump it to 70mhz or so... if that works.. try 1mhz increments until you reach instability...

if your mobo doesnt have any fsb adjustments .. try a software fsb program like H. Oda's soft fsb..

you can find a multitude of these proggies at www.tweakfiles.com

it really depends if its a P2 based Celeron or a Coppermine P3 based Celeron..the P2 variety has a large cap over the die, and the P3 type has a small die the size of a small fingernail. The P2 variety will top out around 600 mhz, the P3 variety will do about 900.

however, you have an LX based motherboard with a max FSB of 83 mhz..you could run at 83 mhz FSB if your components will allow for it..some will, some won't.

good luck.

If thats an Intel Motherboard, then you probably only have the 66/100MHz bus speed choices Maybe 133MHz. If your Celeron is the older PPGA type, you are not going to have much luck overclocking it. The FC-PGA Celeron's in the 533MHz veriety were the good one's. Even then they usually took some voltage increase to get them to run at the 100MHz bus speed. I had one that would do it at 1.55volts. If it is a FC-PGA, and you can up the fronside bus to 100MHz give it a shot. It may do it at default (1.50) volts). You can modify the CPU to default at a higher voltage (1.6volts). Go over to HardOCP and read the aticle there on this modification, but instead use the rear window repair kit to connect the pins. I did and it worked great.

 

[Killrose]

OOPS! Didn't see your link. Sorry, but it looks as though you are out of luck. I see no support for 100MHz fronside bus...

I have
CPU Clock/Spread Spectrum (66-150)
and
CPU Clock Ratio
options in the BIOS

Any help?

First quention, is it a PPGA Mendocino core Celeron 533MHz or a FCPGA Coppermine core Celeron 533MHz?

They have VERY different overclocking abilities. If it's based upon the older .25u Mendocino core your probably not going to be able to overclock it very far at all. If it's based upon the Coppermine core it's quite likely you should be able to get a very good o/c out of it.

BTW, according to the specifications from Soyo it has 16 sets of selectable FSB settings in the BIOS so it's definitely a board you can o/c on.
I'll see if I can find out what specific FSB options are available.


Edit: Put in .18u first originally

 

[Dark4ng3l]

<< the older .18u Mendocino >>

this should be

<< the older .25u Mendocino >>

 

[2k1civicdotcom]

Ya, I am assuming that's what this is for
CPU Clock/Spread Spectrum (66-150), it has, 66,100,133,150 and others inbetween. I will have to take the thing apart to find out what it is. Will let you know. Thanks for looking up the specs, let me know what you find out.

Geez - try it at 100 already. Most likely the worst you can do is have to reset your cmos and change your bios settings back if it totally locks up. It may just run like a champ tho!
(ymmv)

 

[2k1civicdotcom]

waht do i set the clock ratio at if i set it at 100?

 

[Wiz]

iNtel chips are clock locked. So whatever is default for that chip - if it's a 533 then divide by 66 to get: 8

 

[Rand]

I think it's foolish to tell him to just try 100MHz FSB without knowing atything of what chip is in there. Who is to say he doesnt have a .25u Mendocino core Celeron?
in such a case he wouldnt have a chance at the 100MHz FSB, and while usually if it doesnt make it you can just reset the BIOS even if it doesnt POST, there is always the possibility that you may burn out the processor out when trying a jump in clockspeed as considerable as that, expecially with an older .25u processor which rarely tended to make much beyond 600MHz max.

One should always slowly increase the FSB, making large jumps outright is risking more trouble then it's worth.

 

[Wiz]

Rand, -whatever-
no guts no glory - while AMD chips have major horror possibilities from overclocking too much this rarely happens with iNtel. Most of the time worst case is having to reset your bios, no big deal. Note he was given that warning.

(you might also notice people have asked him what he has and so far he just doesn't know)

He's here asking because he wants to overclock, not because he wants to be &quot;safe&quot;.

2k1civicdotcom, if you want to be safe, leave your computer turned off. It's the only way to be sure nothing will go wrong.

If you want to find out if you can overclock, you will have to experiment and take a risk or two. We have all done it, it's usually worth it.

Rand, what &quot;small&quot; step would you propose. He is running 66 FSB now and he's got iNtel so he is multiplier locked. The smallest step he can take is to move it up to 100.

I have a .25u core celeron doing a 50% overclock here, as do lots of people!!!
Of course if his 533 is .25u then his chance of having to do a bios reset are far greater,
but you never know until you try! Since that is the very lowest, smallest step up from where he is that's what I advised him to do. I would try it if it were my cpu.
As always, ymmv and that's just my $.02

 

[AndyHui]

Wiz: you may have a processor that did a 50% overclock, but what was the original speed? 300MHz? 366MHz?

At 533MHz, the original Mendocino .25 micron Celerons are at the top of their physical limit for that particular process. No matter how much voltage or cooling you use, you will NOT be able to overclock it very far.

The steps normally available up from 66MHz FSB are 75MHz and 83MHz FSB. I would suggest that 2k1civicdotcom try the 75MHz FSB. It is HIGHLY UNLIKELY that you will get any further with that processor.

 

[Wiz]

AndyHui:
Thanks for your input. I read his list of speeds above and didn't see 75 &amp; 83. My experience with those is they tend to cause trouble with the HDD and other components anyway. (I see he mentions 'others inbetween')

Did you see where I said &quot;Of course if his 533 is .25u then his chance of having to do a bios reset are far greater&quot;??

Why don't all you guys just tell him the truth?

2k1civicdotcom: unless your cpu is a .18u (if it is the older .25u) you are dead in the water - you are better off just saving up for an upgrade, don't waste your time!
This cpu (if it is the .25u) is the top end of that line and they pushed it as far as they (iNtel) could already.
If it is .18u you will likely be able to set the fsb @ 100 or above and run like the wind.
It makes that much difference!

 

[2k1civicdotcom]

Thanks for all the help guys.

I think my chip is the old style. It is thicker and has a 98 year. #FV524RX533

I founf the manual online and it says this.
This Motherboard is designed to support processors with 100MHz FSB.
However, Socket 370 processors with 100MHz FSB are not available at
present.

I tried just changing it too 100/on and it didn't boot.
