Mirrored channel mode:
In mirrored channel mode, channels 2 and 5 are
unused. The memory contents on channel 0 are duplicated in channel 1, and the
memory contents of channel 3 are duplicated in channel 4. The effective memory
available to the system is only half of that installed. The maximum available
memory (with 16 GB DIMMs) is 32 GB for a single CPU system and 64 GB for a
dual CPU system.
Important:
The memory configuration of channel 0 must match that of channel
1, and the memory configuration of channel 3 must match that of channel 4. For
example, if a 4 GB Dual Rank DIMM is installed into the DIMM2 connector,
then a 4 GB Dual Rank DIMM must also be installed into the DIMM6 connector.
Table 2 on page 65 lists each channel and which DIMM connectors belong to the
channel.
The following table shows the order that memory DIMMs are installed to use a
mirrored channel mode.
