Hey guys, having a serious problem with my new system that i have recently built, i keep getting hardware errors which are causing me to BSOD

At first i thought it was the ram, but ive checked the ram 3 nights in a row and got no errors what so ever.

Im starting to believe its the CPU thats causing me the problems now.

Heres my specs of my system:

Windows XP Service Pack 2
Amd Opteron 165
2Gb Skill Zx Ram
ATI x1900xtx 512mb
300gb maxtor sata hdd
160gb maxtor ide hdd
580w hiper modular psu
Biostar gforce 6100mp skt939 pci-e mobo (MATX)

I want to def make sure its the CPU before i try to RMA (slight problem there, have moved from the US back to the UK, so all my components were bought stateside so hoping i can RMA to AMD UK side)

I mainly seem to get the error when doing something graphical such as watching videos and playing games, but prime95 has crashed twice whilst running with nothing graphical up, and when it does crash whilst doing something graphically intensive it never seems to be around any stressful points.

Anyway another with the badgering on. Heres the Debug of the memory dumps i get. I have about 20+ of them all saying the same thing:

NOTE: This is a hardware error. This error was reported by the CPU
via Interrupt 18. This analysis will provide more information about
the specific error. Please contact the manufacturer for additional
information about this error and troubleshooting assistance.

VAL - MCi_STATUS register is valid
Indicates that the information contained within the IA32_MCi_STATUS
register is valid. When this flag is set, the processor follows the
rules given for the OVER flag in the IA32_MCi_STATUS register when
overwriting previously valid entries. The processor sets the VAL
flag and software is responsible for clearing it.

OVER - Error Overflow
Indicates that a machine check error occurred while the results of a
previous error were still in the error-reporting register bank (that
is, the VAL bit was already set in the IA32_MCi_STATUS register).
the processor sets the OVER flag and software is responsible for
clearing it. Enabled errors are written over disabled errors, and
uncorrected errors are written over corrected errors. Uncorrected
errors are not written over previous valid uncorrected errors.

UC - Error Uncorrected
Indicates that the processor did not or was not able to correct the
error condition. When clear, this flag indicates that the processor
was able to correct the error condition.

EN - Error Enabled
Indicates that the error was enabled by the associated EEj bit of the
IA32_MCi_CTL register.

PCC - Processor Context Corrupt
Indicates that the state of the processor might have been corrupted
by the error condition detected and that reliable restarting of the
processor may not be possible.

Sounds like your getting cache errors in the cpu which are uncorrectable, eg ecc was either unable to fix them or you have turned off ecc in the bios.

If your cpu is not overheating and your voltages are correct then you are probably right in thinking its a cpu problem.

Apart from trying another cpu, and maybe reseating the cpu and power cables I think you might want to contact AMD and ask what they think about a RMA.
