What's the fastest celeron I can upgrade to?

[Ryan]

I have a PII-266 that I am looking to upgrade. I want to buy a **cough** celeron fro my computer, and I am gonna use a PPGA CPU Adapter Board-PII to Socket 370 so that I can use a celeron. What would be the fastest celeron that I could upgrade too?

Your main concern with Celerons should be the voltage. Find out what voltages you mobo supplies (unless the slotket can manipulate the voltage independent of the mobo). The current celerons are around 1.6V I think, while some older ones were at 2.0V.

how do I find out my voltage?

 

[Cosmic_Horror]

firstly find out what brand model and rwevision your motherboard is. then check the manufactures website and look for a bois update. that will tell you what processors are supported.

I already know that my mobo doesn't support a celeron. But it will if i use the adapter I want to buy. The adapter is PPGA, and I know that somewhere down the line intel chaged that, to something like PGA. I think that the highest I can go is to 533mhz.

What SUO meant was that even though you can get a slocket, your booard may not be ableto provide the correct voltage. Older PIIs like yours run on 2.2v. The new Celerons and PIIIs (which likely did not exist when your board was made) run on 2.0v. This means that there is a possibility that your board can only provide 2.2v and cannot be adjusted to supply the 2.0v that the new chips use.

Check the BIOS to see if you can adjust the voltage to 2.0v. If not, check with the manufacturer of the board to see if they have a fix or BIOS update that would make it work.

Buy MSI 6905Master slocket and any new Celeron will work.
I have FC-PGA c533@800 on mobo that even flashes a warning during boot saying
it cannot supply correct voltage. No problem as long as
you set slocket jumpers to whatever you need.

If BIOS doesnt allow to boot for incorrect voltage reason
then go back to previous BIOS revision intil it does.

EDIT: Also I have c600@900 on another mobo which thinks its a P3-900.
Thats what it says on boot screen. (also MSI slocket)

Vrangel, you sure about that? On most slockets setting the jumpers ONLY TELLS the motherboard what voltage to supply. The chip may run at whatever your MB's giving it, but it probably ain't the right voltage.

I was talking about Intel 440BX mobo without any FC-PGA support.
Any BIOS newer than P11 will flash warning before POST
saying that this mobo is unable to supply correct voltage
to FC-PGA CPU. And it wont boot.
So I went several BIOS revisions back until I got P11 which
apparently doesnt know anything about FC-PGA.

EDIT Oh, I bet CPU gets 1.55V from the slocket as set by jumpers because
it is cooled only by some tiny noname fan/heatsink .
And its only warm to the touch. Thats c533@800.

Some of those crappy LX mobo's only ran at 66 fsb and have wacked out voltages for Klamath cpu's.
Be careful.
