Asus P2B-S with new Celeron (Socket 370 Adapter), Overclocking

[Morphosis]

hi folks!
i got an asus P2B-S and a PII 400. now i would like to replace the PII with one of the new Celerons and run it at 100 MHz FSB. but there are four problems:

1. i need to use a slot1->socket370 adapter. will the overclocking still work?

2. according to the manual of my motherboard (ASUS P2B-S) it supports only multipliers up to 6x. is there a way to work around this?

3. where is the difference between INTEL CELERON 533 ***PPGA*** and INTEL CELERON 533 ***FCPGA*** and which one would you recommend and why?

4. has the celeron a FIXED or a MAXIMUM multiplicator (so that i could also run it at 100 MHz, but at a lower multiplicator, if the maximum multiplicator doesn't work correctly)?

thanks a lot for your help!

A Celeron has a fixed (or locked) multiplier. The only way you can overclock is by changing the FSB.

It doesn't matter what mutliplier the motherboard supports, as the Celeron will ignore this and use its own.

The FC-PGA version is a .18u Celeron II. The voltage is lower, at 1.60v. Depending on what version of the motherboard you have, it may or may not support the C2, due to the lower voltage.

In order to run a C2, you will need a BIOS update, and to support the low voltage. The P2B-S may not have settings for 1.60 volts, but has one for 1.80 volts. It should be OK to run at this voltage....for a lot of boards, it's pretty hit and miss, so there is no guarantee that it will work.

You must use a slotket with your C2. It will not affect overclocking.

There are no problems running the PPGA 533, as this is still the older version of the Celeron, running at 2.0 volts. There is no voltage setting problems; the latest BIOS update will also cover it.

Difficult to say which one to recommend. The C2 will be faster though, and it will overclock. The PPGA 533 has very low overclocking potential since it is running close to maximum physical speed.

Speaking only of CPU's, don't get a Celeron unless you only have about $100 to spend. If that's the case get a 533A or a 566. Try to move up to the $200 range and get a Pentium III Coppermine from the cB0 stepping, like a 600E or 650 or even 700. Even not overclocked they'll do as well or better than the fastest overclocked Cele - but they are definitely good overclockers. Avoid the Cele's over 566 - they're too expensive and you can get a P3 for the same money.

PPGA is for the old Cele and FC-PGA is for the new Cele II's (533A and up) and P3 Coppermines. You should not use a FC-PGA chip in a PPGA adapter or board !

Check the mobo maker's site for your board's page and see if you can download an updated BIOS and then 'flash' the new BIOS to your board. Follow their directions exactly and print out their instructions first. BIOS updates often are to allow for faster processors on an older board. Don't flash the BIOS unless you have to.

If your board can handle it, do try to move up to a P3 and overclock that - you won't regret it.

If your mobo can handle it, get a FC-PGA, not PPGA. It depends on your mobo revision and you'll need to update the BIOS. Tell us what board revision you have.

1. Just to be clear, that mobo has NO voltage settings. You MUST get a slocket with voltage jumpers.

2. You should get a FC-PGA slocket, and one that is a good name brand. Some users have had nothing but problems overclocking with a generic cheapo slocket.

3. PIII overclocked is good, but that's assuming that your memory and AGP video are up to the task. Remember this is a BX board, and if your memory can't handle 100+ speeds and your AGP can't handle speeds like 89 MHz, then the CPU will not be cost effective in comparison to an overclocked Celeron. On the other hand, there's no guarantee that an Celeron will overclock properly.

My advice:

Email CompuWiz1 and get him to sell you a guaranteed Celeron 566, with a Golden Orb, and MSI slocket. Reasonable price and nice guy. (Check your mobo revision first.) But if you have chichi RAM and a video card that will handle the fast speeds, you can go the unguaranteed PIII route too.
