Memory configuration guidelines
•
DIMM modules installed in channels A and B must be identical—
A1 and B1 should be the same type, size and manufacturer.
A2 and B2 memory should be the same type, size and
manufacturer.
•
Channel C has no function in mirrored or lockstep memory
configuration. Same rule applies for channels D, E, and F of
processor 2 socket.
•
The effective memory size is reduced by at least one-half in
mirrored memory configuration.
