■ By default, starting with UCSM 2.0.4, DIMMs run in memory performance mode (1.5v) by
BIOS default, which yields faster memory speeds than when the BIOS is set for the memory
to run in power-savings mode. Memory speed is dependent on factors such as:
— CPU choice
— 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.
For more information regarding memory, see CPUs and DIMMs, page 58.
