Figure 37. Memory Population for Single-Channel Failsafe
This configuration:
 The population in Branch 0 meets the requirements for single-channel mode only.
 The population in Branch 1 meets the requirements for dual-channel mode because the
FBDIMMs installed in the DIMM_1 sockets on Memory Riser Boards C and D are
identical in terms of organization, speed, and size.
 The BIOS uses the FBDIMM population of Slot 1 on both Memory Riser Board A and B
(Branch 0) to determine the memory-operating mode. Therefore, the BIOS disables all
FBDIMMs except Memory Riser Board A, DIMM_1 and configures the system for single-
channel mode.
