6.4.3.5 Memory Configuration
The G530 V2 supports the following memory protection modes to increase its availability:
l
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 prevents the system from running on
DIMMs prone to uncorrectable errors, which will cause system breakdown.
l
Mirrored memory: provides maximum protection against failed DIMMs. Uncorrectable
errors in one channel are corrected by the mirror channel.
l
Memory patrol: corrects errors upon detection. If these errors are not corrected promptly,
uncorrectable errors may occur.
To configure memory protection modes, access the BIOS and choose
Advanced

Online Spare Memory Configuration
Online spare memory provides protection against degraded DIMMs by reducing the
likelihood of uncorrected memory errors. This protection is available without any operating
system support.
