Select DIMMs
Select the memory configuration. The available memory DIMMs are listed in Table 4.
Approved Configurations
(1) 1-CPU configuration without memory mirroring:
■ Select from 1 to 6 DIMMs. Refer to Memory Population Rules, page 48, for more detailed
information.
NOTE: When memory mirroring is enabled, the memory subsystem simultaneously
writes identical data to two channels. If a memory read from one of the channels
returns incorrect data due to an uncorrectable memory error, the system
automatically retrieves the data from the other channel. A transient or soft error in
one channel does not affect the mirrored data, and operation continues unless there
is a simultaneous error in exactly the same location on a DIMM and its mirrored
DIMM. Memory mirroring reduces the amount of memory available to the operating
system by 50% because only one of the two populated channels provides data.
