Hi there,

Sorry this must be an (old) faq, but even at the asus site I can't find a
satisfying answer,so i want to ask it here to be sure:

Does my mobo (p4pe blackpearl) supports p4 processors with 90ns or do i
really have to use the older 130ns core? This means that all prescott
processors won't work for at all?? What about the use of just 1 ram-module
when upgrading to 800mhz. Is this just a safe-recommendation or will more
than one ram-module won't work?

thanks for your answer

The list here, doesn't have any 1MB cache processors, so the 90nm
(nanometers) processors aren't listed. This is probably because the
Vcore circuit is not designed for them. Now that wouldn't stop a lot
of people, but what will stop them, is the lack of BIOS support.
Without the proper BIOS support, you are likely to get a "black screen"
on trying one of these. (Before buying a Prescott, you would want
to Google, to see if someone has tried the experiment, and how it
worked out.)

If you wish to stay with this motherboard, snap up a Northwood
processor (0.13u) while you can. They won't be available forever.

With respect to the RAM, the limitation is probably the Northbridge
845PE. If you stick 2x512MB in there, you may have to reduce the
memory clock so the sticks are run at less than DDR400. That
probably means the processor gets slowed down as well, and for most
people, they don't consider that to be worth it. You could shop for
a single 1GB module - for example this one -

http://corsairmicro.com/corsair/products/specs/cmx1024-3200c2.pdf

and that would give you 1GB of memory at DDR400.

You could find an 875/865 motherboard and buy an addition 512MB
module that matches your current one, for the new processor.
That would give the benefit of dual channel memory, which a faster
processor could take advantage of. As far as I know, most of the
Asus 875/865 boards can take a Prescott, but you can check the
cpusupport web page to make certain.
