AFF A400, A800, FAS8300, FAS8700: BIOS MRC mapped out DIMM messages

Last Updated:

Applies to

  • AFF-A400, AFF-C400, ASA-A400, ASA-C400
  • AFF-A800, AFF-C800, ASA-A800, ASA-C800
  • FAS8300
  • FAS8700


  • On these systems, the BIOS might map out memory DIMMs when errors are encountered, such as:

DIMM: B0 mapped out. BIOS MRC mapped out DIMM. Major Code 0x30 Minor Code 0x13

  • The BIOS message uses a two-letter code (DIMM: B0) to identify the DIMM with the error.
  • Example of PANIC message which would cause the DIMM mapped-out situation:

PANIC: ECC error at DIMM-13: CE-04-1944-427DADF8,ADDR 0x15e4014780,(Node(1), Memory controller(0), CH(1), DIMM(0), Rank(0), Bank Group(0), Bank(0x0), Row(0x15c80), Col(0x318)) Uncorrectable Machine Check Error at CPU13. ...
