Can a Prescott-compatible S-478 motherboard take this (or any) S-478
core-duo???

Nope. Just because it uses a Socket with 478 pins doesn't mean it's
Socket478. For example, the Pentium-M uses Socket479 which also has 478
pins but is not compatible with Socket478.

Look at the motherboard manufacturers website and see if they have
released a bios that states it is compatible with core duo chips. If
it's a decent motherboard from Asus or Abit there is a very good chance
it will take a core duo with or without a bios upgrade.

Since there are no Core Duo which are compatible with Socket478 the
above simply is nonsense..

Do you mean there are no Core Duo's that are "physically compatible"
- or - "electrically compatible" with Socket478?

This CPU:

http://www.yqcomputer.com/

Appears to be at least physically compatible Socket478.

What motherboards *ARE* compatible with these Core Duo's, and would
they also take S478 P-4's ?

The easy way to figure out which processors a motherboard supports is to
look up the board on Newegg. If you already have a motherboard and you
want to find out if supports the Core Duo then look it up on the
manufacturers website. The Core Duo is a laptop chip, I doubt that many
desktop boards support it, but I could be wrong since it would be a fairly
good choice for a media center application because it's low power which
means that the system would be fanless.

Sorry bullshit Benjamin but the T2300, T2300E, T2400, T2500, T2600 and
T2700 Core Duo processors all use Socket478.

Nope, they do not. If you and "Intel Guy" had read the intel specs more
carefully you would have noticed that the data sheet says "Package Type:
478". This just means that it uses *some* kind of socket with 478 pins.
That does *not* mean it uses Socket478 which is a certain type of socket
with defined mechanical and electrical layout that also uses 478 pins
but is *not* compatible to the Core 2. In fact, if you both had done
some research before posting you should have learned that the Core
processors with 478 pin package type in fact use Socket479 (note the
"9"!). And you also had learned that "Socket479" does *not* mean it has
479 pins, no, in fact it has 478 pins. It's just called "Socket479" for
the very reason to avoid the confusion that came up here...

Just because the pin count is the same doesn't mean it is the same like
Socket478. Both Socket478 and Socket479 use 478 pins but have a very
different layout, and are mechanically incompatible. So yes, what you
said above *is* definitely nonsense, sorry.

Both. The mobile Core versions use Socket479, not Socket478...


Nope. Read again. It says it uses a package type with 478 pins (and
Socket479 uses 478 pins). It does *not* say it uses Socket478 (which it
doesn't)...


No Socket478 mobo can take a Core cpu (at least as long as intel or
anyone else doesn't come up with some overdrive bastard), period.

This link:

http://www.yqcomputer.com/

Is page 7 of a 20-page article about using a Pentium-M in a desktop
S-478 machine.

Specifically, the ASUS CT-479 adapter is used to connect a Socket-479
Pentium-M to a Socket-478 motherboard.

If the "Core" uses Socket-479, then indeed there is very little
(physically) different about the Socket-479 vs the 478, and what-ever
is different electrically can be solved with this adapter board.

This link:

http://www.yqcomputer.com/ :CAT:-1:LISTINGS:6

Shows what I think is the bottom-view of a socket-478 and socket-479
CPU.

So my question is now: Is this socket-479 core duo:

http://www.yqcomputer.com/

Sufficiently similar to a "Pentium-M Socket-479" to allow the use of
the above-mentioned ASUS socket convertor on a compatible S-478
motherboard?

PS: Did Intel suffer a creativity breakdown in naming the new core,
and they simply called it "Core" ???

Remember this is a "Core Duo", not a "Core 2 Duo". So in all likelihood
this is a mobile part, and it's designed for the S-478 mobile socket,
not the desktop socket.

Right. And if you have read this article carefully you notice that this
is an ASUS proprietary solution which only works in this one type of
mainboard from Asus...


Right, simply because the P-M uses a connector with 478 pin but not
Socket478...


Socket478 and Socket479 are mechanically and electrically (pinout)
incompatible. The signalling is compatible, though.


Nope. As said above, only one Asus mobo is compatible with the P-M CPU
adapter, and this setup only works with Pentium-M, not with mobile Core.
BTW: the CPU in this reference uses 667MHz FSB while P-M uses 400/533Mhz..


No. What's wrong with "Core"?

Bullshit Benjamin, it's an adapter to fit a 479 pin processor into a
socket designed for a processor with 478 pins. You wouldn't need the
adapter if they had the same number of pins and your bios supported the
chip.

There are tons of microATX boards fitted with socket478 that will take
core duo mobile processors, it's nothing new. You have been able to
build a desktop using the Pentium-M for donkeys years.

See here:

http://www.yqcomputer.com/

but that's not really the point.

The point is, how can there be both a Pentium-M ->AND<- a Core/Core
Duo that are both listed as Socket-479?

Are there TWO different specs for Socket-479?

One for Pentium M, and one for Core/Core Duo's like the SL8VQ ???

Note for others: Pentium-M's and some Core Duo's (like the SL8VQ) are
listed as a Socket-479 not because they have 479 pins (they have 478
pins) but because Intel needed to come up with a different name for
that pin-out so they chose "479".

What's strange is that this page:

http://www.yqcomputer.com/

Shows a picture of the pin side of a Pentium-M (left) and Core Duo (on
the right).

The Core Duo has the same pin arrangement as a Socket-478 Pentium (!?)

(why do they look like the old P-3's ?)


Sort of like GM coming out with a new car, and they call it simply
"Car".

Nope. Again for you: just because two connectors use the same number of
pins does *not* mean they are compatible. If they are compatible depends
on several things (lenght and diameter of pins, pin distance, pin
arrangement, connector coding etc). For example, a round connector with
478 pins probably won't fit in a square socket with 478 pins.

Socket478 got it's name from the number of pins. Socket479 didn't, it
also uses 478 pins but with different arrangement so Socket478 and
Socket479 are *not* compatible but they both *do* use 478 pins (that's
why the intel spec site says "478 pins" as packaging type, that does
*not* mean it uses Socket478!)


These boards that take Pentium-Ms are *not* Socket478. They are
Socket479 boards...

You really need to get a clue...
