Low-Voltage DIMM Considerations
The C22 M3 server can be ordered with low-voltage (1.35 V) DIMMs only. Note the following considerations:
■ Low-voltage DIMMs within the server must have the identical manufacturer, type, speed,
and size.
■ Low-voltage DIMMs and standard-voltage DIMMs can be mixed in the same server. Note that
this causes the system BIOS to default to standard-voltage operation (Performance Mode).
That is, the server cannot operate in Power Saving Mode unless all DIMMs are low-voltage
DIMMs.
■ CPUs that have a maximum memory frequency less than 1333 MHz support low-voltage
DIMMs operating in Power Saving Mode only, and do not support Performance Mode.
