My hardware:

CPU: Phenom II 545
Motherboard: Gigabyte MA770T-UD3
RAM: G.Skill F3-12800CL9D-4GBNQ (4GB)

Everything is running at stock speeds and voltages.

I am running Linux (Ubuntu) and have been noticing a few hard lockups over the past week or so. I got around to checking /var/log/syslog tonight and see that there are several "Machine Check Exception" entries. I installed mcelog (a linux program to decipher these errors), but I still don't really know what is at fault (CPU or memory). Here is one of the errors:

HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
MCE 0
CPU 1 0 data cache
ADDR c0ae9480
TIME 1297044291 Sun Feb 6 20:04:51 2011
Data cache ECC error (syndrome 0)
bit46 = corrected ecc error
bit62 = error overflow (multiple errors)
memory/cache error 'data read mem transaction, data transaction, level 2'
STATUS d4004000f1000136 MCGSTATUS 0
MCGCAP 106 APICID 1 SOCKETID 0
CPUID Vendor AMD Family 16 Model 4


As you can see, it clearly says it is a hardware error. It also seems to be related to the CPU cache. What does this mean? Is it definitely a CPU error or could it be the motherboard or RAM?

OK, I guess no one knows what these errors mean. Are there any AMD reps that post to these forums? Anyone that might know whether the CPU is bad or not?

If it turns out to be bad, what is the process of returning it to AMD? How long does it take? I think I am barely over my 30 days at Newegg.
