- I'm not good enough on this to tell you if
it's the CPU, or the motherboard, but it's one of the two, *not* just memory.
What do you base that on? I've seen a lot of different MCE-errors being resolved by finding and replacing flaky dimms.
Because it says NB Array error, and errors in the L3 subcache. I've seen enough memory errors, and not seen an NB array & subcache error.
That does sound like a reasonable guess. However, you presented it as absolute truth. The MCE could just as easily be read as: NB means not IC/DC/BU => actual RAM.
Given that real world figures show bad RAM to be a lot more likely that a bad CPU I'd start by looking at the dimms (or at the very least not exclude it...).
I do just note that there's "No DIMM found for ... in SMBIOS", but I assume that's just a bank that's not filled.
or the SMBIOS data is borked, wouldn't be the first time...
