Does anyone know if the P4C800e will be able to handle a Prescott??

Hi,
Until they are available who knows !!!!!!!!!!!

It looks as though they will initially be supported on socket 478 and then
moving to the land grid array 775 socket .
Chips are expected to be available using the Socket T (775) during more or
less the whole of 2004, but Intel is projecting that its next generation
processor - Tejas - will start to be available towards the end of next year,
and in the middle of next year will move to FMB2, and with Tejas FMB1. These
will all use ICH6, it appears.

Extremely doubtful at this point. While the logic's there, it looks like
Prescott is going to be extremely power hungry, and I don't think that they
way the electrics are laid out on the board will be able to provide enough
juice for it. But who knows, Intel may still be able to pull a miracle out
of their butt. Right now Prescott's looking like a complete failure.
 
Intel say in their spec for the i875p chipset that it supports "a CPU code
named Prescott" - so theoretically any 875p (Canterwood) board should be
able to do so...

Wrong.

In terms of the chipset you MAY be right (I say "may" because Intel has
been chaning the specs on Prescott rather dynamically). However, there
is more to this than just the Chipset. Motherboards have switching
power supplies on them to supply the Vcore power to the CPU. The power
requirements of Prescott will far exceed those of any currently existing
CPU, thus, chipset notwithstanding (and even that is in doubt), you
can't automatically assume that a current motherboard will support
Prescott, because it's Vcore power supply may not have the ability to
supply the over 100 watts of power that Prescott will apparently require.
 
Until we actually see a real live "Prescott" CPU, there is no
guarantee that a given motherboard, incl. this one, can handle
the much higher current demands of this new CPU.

Dont you think, ASUS would already have the new Processor, and been testing
on them for a while.

Thats why they have released BIOS upgrades. It says Prescott Processors Now
Supported.

Intel says the New Processor will work with 800 MHz system bus: Intel® 875P,
865PE, 865G chipsets

The problem is that Intel keeps changing the spec. The Prescott CPU
that the Asus 865/875 boards were tested with at design time will not be
the same CPU that Intel releases. The new design seems to require more
current than anticipated, which cannot be overcome with a BIOS update.
So at this point nobody can say one way or another.
 
I said: "theoretically". As long as no one has seen the final version of the
Prescott it´s of course too early to give a reliable statement about support
for this CPU. I wouldn´t even bet that the latest versions of the P4C800(E)
or P4P800 can handle the Prescott - though Asus boards certainly are the
ones with the highest probability in so far...
