SubjectMCE Errors, Bad CPU, Memory or Motherboard?
This is the first time I have seen an MCE error, googling the EIP value at 
the time of the panic does not return any useful results.

Does anyone know whether it is the CPU or MEMORY that is bad in this
machine? As it shows some problems with BANK4; however, if the CPU is
bad, then it is possible to get all sorts of unpredictable results, right?
