Fix common problems informed me that an MCE  was detected. I'm not familiar with this and it was suggested that I make a post with my diagnostics. Any help on what caused this, fixes, and what to do in the mean time would be appreciated.

Bad memory.  Replace.  Your system event log in the BIOS may have more information beyond DIMM #0 as to which is beginning to fail

Does this mean the memory as actually gone bad or could it be caused by error correcting. The ram I'm using is ECC. Would this kind of error show up if the module had to actually correct something, or does this only come up if the memory is actually dead or dying?

 

Also what kind of test should i run to make sure I replaced the correct module?

I'd say it's bad because it is currently being corrected by virtue of it being ECC.  IMO, ECC is purchased so that you know when one is beginning to return errors so that it can then be replaced rather than waiting for the module to get bad enough that it can no longer correct the errors.

 

The SEL should tell you exactly which DIMM it is (or mce says that it's DIMM0, but I'd trust the SEL more than what mce says for identification)
