Dual-ranked memory sparing
When a dual-ranked FBDIMM is used as spare, the BIOS can
independently select a physical rank on that FBDIMM as the spare unit
and utilize the other physical rank as a normal unit. This selective
sparing ensures maximization of available memory while still providing
RAS.
Note:
Populating differently ranked FBDIMMs for sparing is not a
good practice and may yield unpredictable results.
To configure memory to memory sparing mode:
1
Run BIOS setup. See “Entering BIOS setup” on page 100.

Advanced
menu.

Enter
