FSB for Intel Celeron

[allan r]

O.K..... quick question for those in the know.
Can the Celeron processor only operate with a 66 Mhz FSB?

I am considering purchasing one with the idea that it will be better than an
AMD at the same processor speed, and comparable to a PII for the
applications that I would want it for (mostly games).

I've read a lot about how I can overclock it and that sounds enticing....but
if the overall effect is that my FSB runs slower than what I'm running with
my 300 k6-2 AMD then I'm afraid that the total system performance will be
less than a standard AMD at the same processor speed with a 100 Mhz M/B.

I'm considering the Intel Celeron 400 or higher with either an ABIT BH6 or
DFI M/B.

Yes, all current Celeron's use a 66MHz FSB - wont see a 100MHz 'till the end of the year with a
500+.

I just got my Celeron 400 into the case and motherboard. No matter what I
do, I'm unable to boot at 100. 66 works fine. I'm using the Abit BX6 (BH6
sibling).

Um, the Celeron 400 uses a multiplier of 6; so,
by setting the bus speed to 100 MHz, you are
trying to run the Celeron at 600 MHz. No wonder
the machine won't boot.

If you set your front side bus speed to 83 MHz,
you'll be trying to run the Celeron at 500 Mhz,
which it will almost certainly do just fine.

Hey, why thanks. I'll give it a try.

Do be mindful, however, of the bus speed's effects
on PCI and IDE devices. If you are running a UDMA
IDE disk, you may have to set the disk to run with
a less-aggressive mode (via the BIOS, e.g.). Modern
PCI/ISA devices likely will run fine with the
faster bus, but there is an outside chance of
problems.

Allen,

All Celerons are designed to only run on 66Mhz FSB. Since the Celerons are
multiplier locked the only way to overclock them is via a FSB change. 66 and
100 are the only bus speeds that don't fiddle with the PCI timing. Many are
having good luck with the 300A overclocked to 450. Beyond that there is not
much reliability because the 100Mhz FSB launches the higher speed CPUs into the
stratosphere. Most benchmarks to date indicate that with all else being equal
the performace difference between 66 and 100 FSB is minimal. Therefore you
probably wouldn't notice any difference between a 300A@450 on a 100Mhz FSB and a
466 on a 66Mhz FSB.
