Memory configurations

To optimize server availability, the server 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 server.
•
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.
