94 Using the System Setup Program
Memory Operating Voltage
(Auto default)
If set to Auto, the system sets the voltage to an optimal
value based on the capacity of the installed memory
modules. You can also set the voltage of the memory
module to a higher value (1.5 V) provided that the
modules support multiple voltages. Options are [Auto],
[1.5 volts], and [1.35 volts].
NOTE: BIOS will auto restrict selection if DIMM is not
supporting low voltage.
NUMA Support
(Enabled default)
Enables or disables Non-Uniform Memory Access
(NUMA) support to improve processor performance.
NOTE: This option is available for NUMA systems that
allow memory interleaving across all processor nodes.

(Auto default)
Select the base address register for the PCIe memory
space. Options are [Auto], [32-bit], and [64-bit].
