Mirroring mode
•
In mirroring mode, the memory contains a primary image and a
copy of the primary image. Therefore, the effective size of
memory is redcued by at least one-half.
•
Channel 3 has no function and cannot be populated in this mode.
•
Follow the population rules described in independent mode.
•
DIMM modules installed in channels 1 and 2 must be identical —
1A and 2A should be the same type, size and manufacturer. 1B and
2B memory should be the same type, size and manufacturer.
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 processor 2.
