Cisco UCS C460 M4 High-Performance Rack-Mount Server
CONFIGURING the SERVER
17
■ Eight memory risers with at least two matched DIMM pairs per riser (16 DIMMs total) and up
to six matched DIMM pairs per riser (96 DIMMs total).
Available DIMM Configurations
See Table 6 for the possible DIMM configurations in 2-CPU and 4-CPU systems.
Caveats
■ Memory Mode. System speed is dependent on how many DIMMs are populated per channel,
the CPU DIMM speed support, and the BIOS memory mode. The BIOS default memory mode is
performance mode. However, the BIOS can be changed to support lockstep mode.
NOTE: There are three memory mirroring modes:
1 Intra-socket mirroring
2 Inter-socket cross-memory-controller mirroring
3 Inter-socket complete master-slave mirroring
Mirroring mode can be configured using the UCS Manager BIOS Policy RAS Memory
tab.
