The Intel ICH5R chip on my P4P800-E Deluxe started to smoke and glow red and
my computer shut down and would not reboot.
Is this a "Known Problem" for this motherboard.

This is not a known problem, it's a feature of ASUS mobo's. Glowing and
smoking chips are "eye candy" for those who wish to use clear side panel
ATX cases.

Sounds like it is time for an RMA under warranty. Hope nothing
other than the motherboard was damaged.

This is the only burning case I can remember.

P4P800 burns - problem caused by a short via USB wiring
http://groups.google.ca/[email protected]

There have been a few P4P800 family board failures occurring,
but the boards just failed to POST. Nothing spectacular.

In some cases, a failure like this is caused by a power lead
getting connected to an I/O signal somewhere. This can happen
if there is a failure on a disk drive controller board, via
computer case front panel wiring, or even if something is
shorted on the bottom of the motherboard. Also, if a power
supply fails and delivers higher than normal voltage, that
can toast a whole bunch of stuff. While there is a phenomenon
called "latchup", that can fry integrated circuits, chip
makers have attained very high latchup ratings, making
incidental failure unlikely in normal usage. I've managed
to trigger latchup in a large IC a couple of years ago, but
the chip simply failed to respond, until it had 12 hours to
recover. It never got hot or anything. (And it turned out it
was something I was doing to the IC that caused it to happen.)

Seeing as power supplies have poor reliability, and poor
protection features, the PSU is the first thing I would be
looking at.

Also, take careful note of all the components that were used
in that computer build. It could be, if you reuse the disk
drives, that a drive actually caused this failure, in which
case whatever other computer those drives are connected to,
could fail as well. Use a marker pen to mark all the components
that were in the failed computer, so you can keep track of
them in case there are future failures.

Well...
I've just had a P4P800-VM board turn into toast.
All USB ports failed first - then the video, then the entire board died.
During my attemps at diagnosis, I got third degree burns when I felt the
ICHR chip on the board.
It was red hot! ....another 5 minutes and who knows!

My P4P800SE is in for RMA right now. It worked fine for 2 months. One day,
it wouldn't post. I poked around, swapped various components, no change. I
let it sit powered on for a few minutes, then the ICH5R heatsink was searing
hot. I figured this was a mobo failure so out it came! I'll let you know
the results of the RMA, hopefully next week.

I found another case here - this time I tried search terms "ICH5R"
and "hot"

http://groups.google.ca/[email protected]

It is interesting that no other brands of boards show this problem.

Searching on "ICH5" and "hot" produced mention of a problem with
ICH5, USB and ESD. Unfortunately, the source of the information
is in Chinese. A possible mechanism here would be, a static
discharge coupled into a USB port, causes the Southbridge to go
into latchup.

I guess this isn't an isolated incident.

For anyone who suffered from this, was there something you
did to the computer, just before it melted down ? Like connecting
a USb device ? That might help pinpoint what the cause of the
fault is.

I just got an RMA from Asus. I went out and got a new P4P800-E deluxe right
after this happened because I had no other computer to use. I swapped out
the motherboards and everything worked so there was no damage to anything
else. I had the Asus probe program running with the history function enabled
and at the time it burnt out in showed no abnormal temps or voltages. I hope
this is not a big problem with this board or chip. I did find a couple of
messages on the net for an MSI board having the same problem with the ICH5R
plus the Asus board.

My P4P800-SE died the same way. I was using it without incident for
just about 6 months when it expired. One day it wouldn't boot, so I
opened it up to check cables and such and almost burned my fingers on
the heatsink. Fortunately, I have a good dealer who replaced the board
for me. the same day.

Interestingly enough, a neighbor's machine (another P4P800-SE) expired
in much the same fashion in about the same time frame from purchase.
Again, the same dealer replaced her board without question. I don't
know if it is related to USB or not but I upgraded my powersupply to
a 450 watt unit just to give me a little headroom on bootup and added
another case fan. I asked the tech support person at the dealer if
this was a common fault. He said he had seen it before, but that only
very rarely. This dealer selsl mainly Asus boards, so I guess the tech
guy would know.

I really hope this was just a bad run of boards as I have been using
Asus boards for some time and have never had a board failure before,
but then again, I also swore by Fujitsu as being the most reliable
hard drive made. :wink:
 
My P4P800-E died just the other day, and when I checked the ICH5 it
had a large burn mark across it. The failure came immediately after
plugging in a memory card reader into the second front USB port. (The
first had a Palm interface cable plugged in, but not connected to the
palm.) Other than that I think no USB ports were in use at all. I'm
running linux and thought it was a hotplug problem at first but I
guess not.

Welll my new P4P800E Deluxe just burnt out after 4 weeks. Same thing as
before the ICH5R chip burnt up.
Still waiting for my first one to come back from ASUS. I hope they fix this
problem 2 boards same version (1.0) same problem.
I'll never buy ASUS again......
