Whats different in P4C800E and P4P800E Deluxe

[Malam]

What are the major differences between these two motherboards in
layman terms? Is there a noticeable difference between the onboard LAN
used by these boards?
Thanks.

no,one uses registered memory (ecc) and also has pat
technology...(p4c800e), although asus has an undocumented method to
enable pat on the p4800e as well...

P4C800-E
- 875 chipset - capable of 25% overclock without video artifacts
- uses unbuffered memory, either with or without ECC - ECC allows
error checking, for server type applications
- gigabit ethernet chip connected to private bus (CSA). Allows
network access to occur without affecting other PCI bus activities.

P4P800-e
- 865 chipset - Asus "hyperpath" feature, is a hack to the chipset
that allows the same optimization as the "PAT" feature officially
supported on the 875 chipset.
- uses unbuffered memory, but will not use any ECC info, if it is
present on the DIMM. (You could plug an unbuffered ECC DIMM into
the socket, but the ECC bits would be ignored.)

I see a trivial difference in the AC97 audio chips, optical
SPDIF on the P4P800-E.

If you are interested in overclocking a board that uses the
865PE northbridge, i recommend you read this first.

If you are not planning on overclocking, either board is
a good choice. The use of the private bus (CSA) for the
Ethernet chip, is generally useful in a server type application,
like if you use the P4C800-E as a SOHO file server.

If this board is being used for your desktop, there aren't too
many normal surfing, email, office application scenarios that
will benefit from the P4C800-E's features. The same is true of
the inclusion of ECC protection for the memory - memory is
good enough these days, that ECC doesn't have too much utility
on a desktop.

What remains, is the overclocking issue. If you plan on changing
the CPU clock from 200MHz to 250MHz or higher, read the thread
above, and decide whether the P4P800-E would be a good choice
or not.

HTH,

Paul, I can recommend P4P800-E. I'm not interested in overclocking just a
solid platform that performs well. I had some correspondence with you some
time ago on here complaining about poor benchmark performance with a 3.0GHz
800FSB Prescott and 2-2-2-5 DDR400 compared to a 2.8GHz 533FSB Northwood
with standard DDR333. I never resolved that issue so sold the chip and board
components on to someone else as they did work but not well in my
configuration. I've since bought, after looking elsewhere, the exact same
board again (mainly due to it's SATA and other capabilities) and fitted a
3.2GHz Prescott with the Corsair 2-2-2-5 and everything is singing along
very nicely now.

I swear I will never understand why this Old Wive's Tale so robustly lives on.

ECC is *always* preferable if/when available; "server" or "desktop" makes no
difference, as data corruption from flaky/bad RAM can occur just as easily in
either scenario, and can certainly have just as unpleasant an impact. If
anything, it is even more critical for the typical single-desktop SOHO user,
who historically does a lousy job of backing up their data (not that ECC is an
acceptable substitute for proper backup procedures, but the point remains...)
