Mirroring mode
• For mirroring mode, the memory contains a primary image and a
copy of the primary image. Therefore, the effective size of the
memory is reduced by at least one-half.
• Channel 3 has no function and cannot be populated under this
mode.
• Follow the population rules described in independent mode.
• DIMM modules installed in channels 1 and 2 must be identical —
memory modules in slots 1A and 2A should be the same type, size
and manufacturer. The same applies to slots 1B and 2B. However,
it is not necessary for slot A to have the same memory module as
slot B within a channel.
• The same rule applies to the processor 2.

Notes: 1. Place DIMMs in “X” location.
2. DIMM population must correspond to the above tables.
3. DIMM modules support 1 GB, 2 GB and 4 GB DIMMs.

on availability).
5. Do not mix UDIMMs with RDIMMs.
