Figure 42. Memory Population for Dual-Channel on Both Branches with Sparing
This configuration:
This configuration provides the highest system performance because the use of both
memory branches doubles FBD bandwidth.
Minimal configuration is either two single-ranked FBDIMM pairs per branch (eight
FBDIMMs total) or one dual-ranked FBDIMM pair per branch (four FBDIMMs total).
The FBDIMM lock-stepped pairs installed in identically numbered DIMM slots across
branches do not have to be identical in organization, size, and speed. However, it is
recommended identically numbered DIMM slots be populated with identical FBDIMMs to
improve memory performance.
User must Configure Memory RAS to Sparing in BIOS Setup.
Sparing is configured independently on each branch.
The single largest lock-stepped FBDIMM rank on each branch is selected as the spare
unit. The spare unit may be located in different FBDIMM slots for the memory riser
boards on each branch.
