DIMM Voltage Preference
Options include:
• Optimized for Performance (default):
This sets the voltage for a system with all LV DIMMs to 1.5V only if that provides a
performance advantage. Otherwise, DIMMs are left at 1.35V.
◦
◦ LV DIMMs are set to 1.5V.
• Optimized for Power—LV DIMMs run at 1.35V, even if this requires memory to run at a lower
frequency. The system does not allow 1.35V operation unless all installed DIMMs in the system
are LV DIMMs.
