WMIxWDM 106 "Machine Check Event reported is a corrected error"

[Thorsten Engler]

On a new dual Opteron system Windows 2003 starts giving this message every
few minutes. The first few times were during the setup already.

System: Tyan S2895, 2x AMD Opteron 246, 4x 512MB RAM (2 per CPU).

Main question is how does the information in the Data map to the MCE/MCA
registers (as defined in "
AMD64 Architecture Programmer's Manual Volume 2: System Programming, 9.3
Machine Check MSRs")?

Is there already a program available somewhere that can decode the Data (for
Opterons) into a human readable text? Otherwise I'll write one once I know
how that Data maps to anything that's specified somewhere.

Event Type: Warning

Event ID: 106

This occurs under both Win2003 SP1 (32bit) and Win2003 SP1 (64-bit Extended
Systems). The event log information posted is from 32bit.

Not here. This is a ffree group which is provided by Microsoft, but
most of those who are posting here regularely are volunteers, not paid
for this, so you can not expect a guarantee other that we try to do
our very best.

We are getting exactly the same errors on our S2895 based machine. Did
anyone find out what was causing the error? We suspect it's a CPU, but
are unsure.

I had the same problem. I set up the same hardware running Opteron Troy
E stepping cores and 2 gig of RAM (2x1gig sticks) and ran fine for 3
years running Server 2003 64-bit Edition.

We needed to add more RAM, so I got another 6 gig and loaded them on
for a total of 4 gig per CPU. The result, I got WMIxWDM Event 106
warnings in Windows and the occassional bit of data corruption and
occasional blue-screen reboot.

After testing, I thought for sure it was one of the CPUs. With 2x1gig
chips, each CPU was only addressing 1 stick, thus, addressing in 64bit
single channel mode. Adding 3 more sticks enabled it to address the RAM
in dual channel mode at 128 bit. Since AMD CPUs have integral RAM
controllers and everything Microsoft says "It's a problem with the CPU",
I believed it. I saw 0100: in the Event report showed the actual CPU
number that reported the error. In my case it was always "01". The
thing that convinced me it was the CPU was when I swapped the CPUs and
all the errors then came from "00".

So, it was the absolute tail-end of the CPU's warranty with AMD, after
talking with a tech who was as clueless to the mysterious "Event ID:
106" as I was and was hunting forums with Google as well, he set me up
to RMA it, which I did.

The new CPU came in and when I put it in, same problem; this time,
reporting it was from the CPU I left in the machine. Now I figure
EVERYBODY is WRONG (AMD, Microsoft and Tyan) and the problem HAS to be
RAM related. I spend an evening working late in the office adjusting
timings to the RAM when I hit upon the magic setting.

The solution: I dropped the clock of my RAM from "Auto" (166Mhz) to
"Manual 133Mhz". Everything became stable. I slowly put everything
back the way it was and left the RAM under-clocked.

My theory. Event 106 is an ECC RAM error it recovered from. The
problem though is in the RAM errors it doesn't recover from
(blue-screen) or the RAM errors it fails to catch. It took me two weeks
to nail this one down after finding limited to no information online.

Sorry to grave-dig an old post, but maybe if I posted my solution,
it'll save someone else somewhere the headache. :)

Thanks a lot, I had this problem and I have solved it by turning off the
ECC in BIOS. Sure, it's not the solution, but the 106 error stopped.
I don't know whether it is a CPU problems, or the malfunction of RAM
controller. But the event id 106 indicated, that memory controller have
corrected the error in RAM.

Sorry for my english.
