Has Asus given up on ECC RAM? Or is there no ECC version of DDR2 memory?
I checked the specs. for all their latest P5xxxx boards and found none
that could use ECC RAM.

Whether you vote Democrat or Republican in November, the country will
still be run from boardrooms in the USA and elsewhere, not by your
elected representatives.

I checked a couple of Asus manuals, then went to the Abit site
and clicked on the specs for one of their 925X boards. I also
checked an Intel board with a 925X on it, and none had ECC.
So, I downloaded the 925X datasheet from Intel (the Northbridge),
did a find on ECC, and it says ECC is supported. But, a few
more clicks brought me here:

"ECC Check Byte: These signals require a 6-layer board to be
routed."

Maybe the expense of a six layer board has pissed off
the motherboard makers ? What the six layer thing means, is
the pins used for ECC on the bottom of the ball grid array
package are buried near the center of the chip, and it
is impossible to route the signals out from under the
Northbridge unless a six layer board is used. You may have
to find a "server class" motherboard product, to find someone
willing to spend the extra 10% cost on the PCB blank, to
get ECC. Good luck in your search.

I checked the Crucial site and both ECC unbuffered DDR2 and
non-ECC unbuffered DDR2 sticks exist, so that isn't the problem.

HTH,

ECC RAM is basically only used in dual processor Server motherboards, and in
some of the new AMD 64 bit CPU motherboards.

The Asus P4C800E supports ECC. It is a P4, not AMD, MB. And it sure
ain't a dual-CPU MB, unless you think HT delivers dual-CPU performance.

Asus must satisfy the biggest piece of the market first, and ECC is
not required by commodity SOHO users. As long as ECC costs more,
even by a tiny percentage, the high-volume PC box vendors won't
include it.

Only egomaniacs, who believe that their data has value, will insist
on frills like ECC, HD backup, and AC line conditioners. ;-)

I have/do all of the above: ECC RAM on every computer I've built, weekly
full backups and nightly differential backups to DAT tape, UPSes with at
least basic line conditioning.

And I thought I was the only such egomaniac.

I use ECC memory to minimize chances of trouble.
I don't overclock to minimize chances of trouble.
I hate crashes and other trouble that cost me a lot of
extra work and lost files.
Backup of some important files saved me many times.
A UPS save me many trouble because I have power outage
10-20 times every year.
