I
After installing the DIMMs the necessary specific settings have to be
done within the BIOS of the server. See the "D2870 BIOS Setup Utility
for PRIMERGY RX600 S5" manual for detailed information.
Spare mode
In spare mode, one pair of DIMMs will be spare for the other pairs. The spare
DIMMs must have the same capacity or higher than the other DIMMs.
DIMM sparing only relates to BOBs. There is no sparing over memory boards
or CPUs.
