Memory configurations
To optimize compute module availability, the compute module supports the following AMP modes:
• Advanced ECC—Provides up to 4-bit error correction and enhanced performance over Lockstep mode.
This mode is the default option for this compute module.
• Online spare memory—Provides protection against failing or degraded DIMMs. Certain memory is
reserved as spare, and automatic failover to spare memory occurs when the system detects a DIMM that
is degrading. This allows DIMMs that have a higher probability of receiving an uncorrectable memory error
(which would result in system downtime) to be removed from operation.
Advanced Memory Protection options are configured in the BIOS/Platform Configuration (RBSU). If the
requested AMP mode is not supported by the installed DIMM configuration, the compute module boots in
Advanced ECC mode. For more information, see the
HPE UEFI System Utilities User Guide for ProLiant
Gen9 Servers
