14.2.6 Mirroring Population Rules
Memory mirroring relies on the dual-channel mode of operation with both branches enabled.
The two branches provide mirror copies of each other for redundancy. Therefore, the system
must operate in dual-channel mode with an identical memory configuration between channels
on one branch (for dual-channel operation) and an identical memory configuration between
branches (for mirror support).
Figure 43. Memory Population for Mirroring
This configuration:
 The minimal mirroring configuration is identical FBDIMMs installed in the DIMM_1 slot of
all four memory riser boards. The user can populate additional slots to increase system
memory as desired.
 FBDIMMs installed in identically numbered DIMM slots on ALL memory riser boards
must be identical in organization, size, and speed for dual-channel operation.
 The User must Configure Memory RAS to Mirroring in BIOS Setup.
 Branch 0 (Memory Riser Boards A and B) is mirrored with Branch 1 (Memory Riser
Boards C and D).
Note: The BIOS Setup Memory page displays the state of the FBDIMMs. See Section 15.2.
