Difference between Northwood P4 and P4

[Jim]

Is Northwood P4 the same as P4? Are they fully compatiable?
Do you think DigiMatrix support Northwood P4? The following table is published on Asus web site at http://taiwan.asus.com.tw/support/cpusupport/cpusupport.aspx.

Do you think DigiMatrix support Northwood P4? The following table is
published on Asus web site at
http://taiwan.asus.com.tw/support/cpusupport/cpusupport.aspx.

The Northwood is a socket 478 P4 as opposed to the earlier Williamette
which used a different socket. The Northwood label was dropped on
processors above 2 GHz as no Williamette cpus were made above this
speed. The Northwood cpu will work fine in the board you show.

Thank you

Yes, this table looks like a Northwood table. If you go to
processorfinder.intel.com and select P4 Pentium, you will get
a long list of P4 processors. Near the bottom are a mix of
Willamette 0.18u 256KB cache processors and the others are
Northwood 0.13u 512KB cache processors. The fact that the
above table skips from 1.6GHz to 1.8GHz, means Asus is not
specifying Willamette, but only selecting the Northwoods.

The above table contains no FSB800 Northwoods.

Neither does the above table contain any 90nm 1MB cache Prescott
processors. The 1MB cache is what tells you they are Prescott.

There are Celeron processors based on the Prescott core -
they are called Celeron D and have 256KB cache and 90nm
feature size. They are not in this list either.

So, the list above is filled with old processors, and it
is becoming increasingly difficult to find these at
retail. Eventually Northwood will be phased out.

What Intel is selling currently is listed here:

http://www.intel.com/intel/finance/pricelist/

The following processors from the Intel pricelist will
fit your Digimatrix. Asus doesn't list the 2.7GHz and 2.8GHz
Celeron, but there is a good chance they will work anyway.
These should still be available at retail.

Intel Pentium 4 Processor Desktop (mPGA 478)
2.80 GHz w/ 512k L2 cache 533 MHz FSB (.13) $163 $163 (68W)

Intel Celeron Processor Desktop (mPGA 478)

Williamette CPUs can be socket 478 as well.

Yep, got a 1.7 sitting on the shelf in the 478. Any takers?

Williamette CPUs can be socket 478 as well.

The Northwood label was
The Willamette 423 socket is a P4
The Northwood 478 socket is P4,which is available over 2.0 ghz
The Celeron 478 socket is a P4
The Presscott 478 socket is a P4
The Prescott 775 socket is a P4
The Northwood 478 socket 3.4 EE is a P4

nice try, like i said I have a willamette on the shelf in a 1.7 256cache
400mhz. I forgot it was so when i tried to plug it in an 865 based mobo and
it would not work (works perfectly in a p4pe 845 board).

actually Intel defines it as:

You can't tie the processor core to the socket configuration.

There have been 3 core families for the Pentium 4, all considered to be
Pentium 4's:

-Willamette (earliest) up to 2.0 GHz
-Northwood, 1.6 GHz to 3.? GHz (at least 3.06)
-Prescott, 2.4 GHz to ??

[I'm not absolutely certain of the speed ranges]

There was some crossover on the socket configurations as well as
substantial overlap on the speed ranges.
