Can I put a socket370 P-3 in a socket 370 P-2 board

I have a board whose manufacturer's documentation (which is moderately old
and probably has never been updated) says that the board supports socket 370
Pentium II CPU's. Am I likely to be successful in using a socket 370 P-III
with this board or are they simply incompatible?

Thanks in Advance

They are no Socket370 P2s, only Slot1. Maybe your'e thinking of the
P2-based Mendocino, PPGA Celerons.

What he said.

That said, you should have no trouble using 100mhz FSB 2.0V P-IIIs (up to
650mhz, in some cases IIRC). If it supports the lower voltages, it should
take 100mhz FSB P-IIIs up to 1ghz, and non-Tualatin Celerons (up to 1.1ghz?)

If it supports the 133mhz FSB, it should support all non-Tualatin P3s and
Celerons.

Odds are if it doesn't explicitly mention support for the Tualatin/FCPGA2
CPUs, it doesn't support them.

All of that said, I have in my hot little hands the following:
1. Two different Single Board Computers, each with a Socket 370 and
both labeled P-II

2. Documentation for one of the SBC's downloaded from the manufacturer
which explicitly says that the board takes a P-II and also supports a
Celeron.

3. Items found on the web-site of the other SBC's manufacturer which
categorize the board as taking a P-II.

BUT ... If I can successfully use a 100MHz P-III on these boards (both of
which claim to support 100 MHzFSB) then the P-II existence or non-existence
isn't an issue because I'll get a P-III for them.

Thanks for all of the good stuff.

In that case I would be very skeptical of the manufacturer's
documentation and products, given that Intel never manufactured a PII in
the Socket 370 form factor - a fact easily verified with a visit to
processorfinder.intel.com

Ahh, you've got a single-board computer. That changes things a lot
here! Chances are that you're dealing with either a Mobile PII
processor or possibly an Embedded PII processor. Intel has all kinds
of different versions of their embedded and mobile processors that do
not exist as desktop chips (and which can't generally be purchased at
retail, only through OEMs). Of course, even there I'm not aware of
any socket 370 PIIs, but they may exist since I certainly don't know
all of Intel's produce line-up. You might want to double check to
make 100% sure that it is socket 370 before you go any further, Intel
does have other sockets they used for their mobile parts that might
look the same from the top but are totally different on the bottom
(and more importantly, they are totally different electrically).

Unfortunately Intel's website is a little weak on the documentation
for these products are they aren't really current products
(particularly the mobile PII, which is what I suspect you're dealing
with here, the embedded chips usually don't use a socket).

There's a strong probability that this is all the board supports.
Also keep in mind that with a single board computer things like power
consumption (ie the voltage regulators used) and heat are going to be
much more constrictive than for a desktop system. So even if the
board could theoretically support a faster chip it might not be able
to provide enough juice for it.

Really the manufacturer of the SBC is about the only one who's going
to be able to tell you anything meaningful about what processors it
supports. These sorts of things are quite a bit more complicated than
desktop systems. As a general rule, SBCs are NOT designed to be
upgraded by the end user, so usually you're options are pretty slim.

Labelled Pentium II on the processor or on the SBC board? If the processor,
then this may be something intel produced later for the embedded market...
Intel has produced a number of processors for embedded markets that don't
make it into standard PC OEM channels, and this may be one of them.

If it'll match the voltage -- and I think 100mhz FSB PIIs were 2v as well --
then one of the first generation (pre-Coppermine) PIIIs should work even
withoug explicit BIOS support. Models with a lower voltage probably won't
work in older boards.

Be very careful there; the current embedded PII 266 and 333 use an otherwise
unused 615-pin socket. BGA, I think.

The sockets themselves are labeled PGA 370 and they match exactly the
Socket 370 on a board we just bought with a P-III installed. The socket is
apparently from the same socket manufacturer so at least the socket is
right, though that's no guarantee aboutt he wiring to it.

On one of the boards there are jumpers for voltage so I think that I
should be all right there as well.

I finally tracked down documentation that's probably for the board
that's labeled "P-II SBC" and it explicitly says that the board supports
Celerons and P-III CPU's so the question of using a P-II in that board's
Socket 370 is mooted. But the other board's [It's a CI7BM] documentation --
verifiably from the manufacturer -- says in one place that the board accepts
a Pentium-II and in another place says that is supports a Celeron (and
Coppermine with later versions as well).
I have seen a few Socket 370 P-II CPU's being sold on eBay lately so I
know that they exist. But since my goal is for the best [i.e. fastest]
processor I can get, I'm certainly going to use a P-III in the first one and
will also try one in the second -- since the documentation says that the
board's CPU voltage is selectable and that the selection includes 2.0v so I
should be okay electrically.
If the results are anything but positive, I'll post again, otherwise
assume that I'm successful.

Thanks to all for information and suggestions.
