Memory Sparing Support – PowerEdge M710HD
NOTE: For memory sparing support, your system must be installed with Intel Xeon
5600 series processors.
Memory sparing (spare bank) is supported in systems that have one of the
memory configurations shown in Table 3-9.
The memory sparing feature must
also be enabled in the Memory Information screen of the System Setup
program. See "Memory Settings Screen
" on page 140 . To use memory sparing,
you must disable node interleaving.
Independent Channel Mode (Optimizer Mode) – PowerEdge M710HD
In this mode, all three channels are populated with identical memory
modules. This mode permits a larger total memory capacity, but does not
support the reliability features of the other modes. To enable this mode,
select the Optimizer option on the Memory Settings screen of the System
Setup program. See "Memory Settings Screen" on page 140.
A minimal single-channel configuration of one 1 GB memory module per
processor is also supported in this mode.
