— DIMM choice
— DIMM population (how many DIMMs per channel are populated)
— BIOS setting.
For the DIMMs to run in power-savings mode (1.35 V, if the DIMM supports this), change
the BIOS setting to power-savings mode.
■
With 3 RDIMMs populated per channel, memory always runs at 1.5 V regardless if the BIOS
setting is power-savings mode (1.35 V) or performance mode (1.5 V).
■
With 3 LRDIMMs populated per channel, memory can operate at 1.5 V or 1.35 V, depending
on the BIOS setting.
