Using the System Setup Program
Description
Enables or disables the memory turbo mode.
Enables or disables the memory to run in closed-loop
thermal throttling mode.
Select the type of memory operation if a valid memory
configuration is installed.
• Optimizer Mode: The two memory controllers run in
parallel 64-bit mode for improved memory
performance.
• Spare Mode: Enables memory sparing
• Mirror Mode: Enables memory mirroring
• Advanced ECC Mode: Controllers are joined in
128-bit mode running multi-bit advanced ECC.
Enables or disables DRAM scrubbing.
DRAM scrubbing is the ability to write corrected data
back to the memory once a correctable error is detected
on read transaction.
Enables or disables patrol scrubbing.
Patrol scrubbing proactively searches the system
memory, repairing correctable errors.
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.
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.
