Memory

To view memory details of the selected host, select the Memory page from the drop-down menu.

Parameters Description

Total memory

Displays the total size of the memory populated on the board.

Operating frequency

Displays the frequency at which memory on the board is operating.

Operating voltage

Displays the voltage at which memory on the board is operating.

Configured AMP mode

Displays one of the following AMP modes:

  • The system is configured for AMP with A3DC.
  • The system is configured for AMP with the Advanced Error Correcting Code (ECC) engine.
  • The system is configured for AMP with the LockStep engine.
  • The system is configured for mirrored memory protection. All memory banks are duplicated in mirrored memory, as opposed to only one for online spare memory. If enough ECC errors occur, the spare memory is activated and the memory that is experiencing the errors is disabled.
  • The management software cannot determine the AMP, or the system is not configured for AMP.
  • A single spare bank of memory is set aside at boot time. If enough ECC errors occur, the spare memory is activated and the memory that is experiencing the errors is disabled.
  • The system is configured for AMP with the XOR engine.
  • The management software cannot determine the AMP, host OS may not have provided it yet.
AMP mode status

Displays one of the following AMP modes statuses:

  • The system is protected by AMP in the A3DC mode.
  • The system is protected by AMP in the Advanced ECC mode.
  • The system is protected by DIMM Error Correcting Code (ECC) only.
  • The system was protected, but AMP is engaged. Therefore, AMP is no longer available.
  • The system is protected by AMP in the A3DC mode. One or more DIMM faults have been detected.
  • The system is protected by AMP in the Advanced ECC mode. One or more DIMM faults have been detected.
  • The system is protected by AMP in the LockStep mode. One or more DIMM faults have been detected.
  • The system is protected by AMP in the mirrored mode. One or more DIMM faults have been detected.
  • The system is protected by AMP in the hot spare mode. One or more DIMM faults have been detected.
  • The system is protected by AMP in the XOR memory mode. One or more DIMM faults have been detected.
  • The system is protected by AMP in the LockStep mode.
  • The system is protected by AMP in the mirrored mode. No DIMM faults have been detected.
  • The system supports AMP, but the feature is disabled.
  • The system is protected by AMP in the hot spare mode. No DIMM faults have been detected.
  • The system does not support AMP, or the management software cannot determine the status.
  • The system supports AMP. The feature is enabled but not engaged.
  • The system is protected by AMP in the XOR memory mode. No DIMM faults have been detected.
  • The management software cannot determine the status, host OS may not have provided it yet.
