
Use this feature to configure Advanced Configuration and Power Interface (ACPI) power
management settings for your system.
NUMA
Select Enabled to enable Non-Uniform Memory Access support to enhance system
performance. The options are Enabled and Disabled.
UMA-Based Clustering
The options for this feature are Disable (ALL2ALL) and Hemisphere (2-clusters). The options
are only available when SNC is disabled.
WHEA Support
Select Enabled to support the Windows Hardware Error Architecture (WHEA) platform and
provide a common infrastructure for the system to handle hardware errors within the Windows
OS environment to reduce system crashes and to enhance system recovery and health
monitoring. The options are Enabled and Disabled.
High Precision Event Timer
Select Enabled to activate the High Precision Event Timer (HPET) that produces periodic
interrupts at a much higher frequency than a Real-time Clock (RTC) does in synchronizing
multimedia streams, providing smooth playback and reducing the dependency on other
timestamp calculation devices, such as an x86 RDTSC Instruction embedded in the CPU.
The High Performance Event Timer is used to replace the 8254 Programmable Interval Timer.
The options are Disabled and Enabled.
