I have the Asus P4B266. It has the P-IV 1.8ghz, but I want to put the
Pentium IV 3.7ghz in it. I know Asus has a bios update to accommodate
processors over 2.9ghz. I really want to upgrade to the Pentium® 4 Processor
Extreme Edition supporting Hyper-Threading Technology, 3.7ghz, 1066mhz FSB.
My current bus speed is 533mhz, and the motherboard has the 845D chipset.

1) Do I really have to worry about the Pin Count and Socket Type? If so, how
do I find this info? I don't see it in the Asus manual.

2) Can I assume because there is already a P4 1.8ghz on the board that a 3.2
will fit and match just fine? If no, why?

3) Is there anything else I need to worry about?

1. Yes!
2. No!
3. You'll need to purchase a newer motherboard!

Won't this one work with my motherboard? Don't all I have to do is take out
the old chip and put in the new one?

I have Asus P4B266, chipset i845D, southbridge 82801BA(ich2)

According to ASUS, your motherboard will support
up to a 2.4GHz Intel CPU.

This is what the manual states..

Currently, ASUS P4B266 series motherboard can support the latest Northwood
Pentium 4 processor to 2.4G.

Check with Asus before assuming that a BIOS upgrade will achieve what you
want..

No. This Intel Prescott P4 CPU needs a motherboard that can
operate at 800 MHz FSB and a more recent chipset, such as the
i865 or i875. Not even a bios update will make the older ASUS
P4B capable of running the P4 Prescott, even if the motherboard
comes with a Socket 478. A better solution would be to upgrade
to an ASUS P4P800SE-Deluxe along with associated memory and
other peripherals that will work with the Prescott P4 CPU.
What you really wanted is a completely new system based on,
for instance, Intel's Socket 775 design with the i945 or i955
chipset, per our specs. It is 2.5 generations newer than your
P4B.

Thanks everybody. I believe the manual came out before there ever was
anything higher than a 2.4ghz. I have posted a question to the Asus forum on
the Asus website, but it could be quite some time before I get a reply
there.

Your P4 is a Socket 478 which means it has 478 small pins
that stick into holes on the socket. The newer CPU is a 775
which uses a different construction with pad contacts...

We are in no doubt that the manual was published before the advent of the
bigger CPU's, but that doesn't alter the fact that a BIOS upgrade will not
automatically make all socket 478 boards compatible with all 478.. CPU's..

John,

As Carey said, your board will only support up to 2.4 ghz. You need a new
set up before getting this.
