not sure what this MCElog is telling me

my hardware is Asus KGPE -D16 motherboard with 2 Opteron 6234 sample CPUs running quad channel ram ( 4 sticks per cpu).
I have been having reboot issues and been through everything I can think of trying to fiure out what is going on.
I installed the MCE log onto my system which is Linux Crunchbang x86_64
the mcelog shows
mcelog: failed to prefill DIMM database from DMI data
mcelog: mcelog read: no such device
"Unknown CPU type vender 2 family 15 model 0
Hardware event. This is not a software error
CPU 0 Bank 4
Misc c010000001000000
Time 135338494 Mon Nove 19 20:14 :57 2012
STATUS fa0008000020c0f mcgstatus 0
mcgcap 107 apicid 0 societ id 0
cpuid vender amd family 21 model 0
it then repeats through the other cores on cpu 6 bank 4,cpu 12 bank 4, cpu 18 bank4.
then my system rebooted and repeated the exact same log.
is this saying it is a memory problem? I did run Memtest+ 4 pass's which took 18 hrs to do and it passed.

Try another distro as a live cd to see if the same problem happens. I'm pretty sure this issue is related to the kernel.

You could also try grab the config used to create your distros kernel, grab the source code your distro used to create it, and load that .config in make menuconfig to see that it was configured properly for a system like yours.

failed to prefill DIMM database from DMI data
That seems to me to be the material error.
You've checked out the cpu can drive the dimm, and that seems OK An easier check would be to remove dimm 4. That clears the 'DIMM' bit

Now check out the 'database' and the 'DMI data' bits. This error could be a read error, a write error, or a memory error. It could also be a failure to create the dmi database.

This seems to have already happened to many users, and they found the solution.

It's also stated in the FAQ for MCE log:
