Indicates all DIMMs in the system are operating at 1.5
volts.
Indicates all DIMMs in the system are operating at
1.35 volts.
This setting indicates the memory operating voltage
will be set automatically by the Memory initialization
code and depending upon the installed DIMM's
capability and the memory configuration of the
system. This is the default setting and will set the
Memory Operating voltage to the POR voltage.
