Errata for 4th gen Intel CPU:s (Haswell):
HSD131. Spurious Corrected Errors May be Reported
Problem: Due this erratum, spurious corrected errors may be logged in the MC0_STATUS register
with the valid (bit 63) set, the uncorrected error (bit 61) not set, a Model Specific Error
Code (bits [31:16]) of 0x000F, and an MCA Error Code (bits [15:0]) of 0x0005. If CMCI
is enabled, these spurious corrected errors also signal interrupts
Implication: When this erratum occurs, software may see corrected errors that are benign. These
corrected errors may be safely ignored.
Workaround: None identified.
Status: For the steppings affected, see the Summary Table of Changes.

edit: i have done the bit calculations and concluded that HEX error codes that
Starts with one 8, 9, C or D, and ends with F0005 falls into the description of this errata.
My conclusion (so far):
If you have one of the CPU models described in the errata, and get an error of:
MCA: Bank x, Status 0x8xxxxxxxxxxF0005
MCA: Bank x, Status 0x9xxxxxxxxxxF0005
MCA: Bank x, Status 0xCxxxxxxxxxxF0005
MCA: Bank x, Status 0xDxxxxxxxxxxF0005
...it could be due to this error in the CPU.
