NUMA
Use this feature to enable Non-Uniform Memory Access (NUMA) to enhance system
performance. The options are Disabled and Enabled.
UMA-Based Clustering
When this feature is set to Hemisphere, Uniform Memory Access (UMA)-based clustering
will support 2-cluster configuration for system performance enhancement. The options are
Disabled (All2All), Hemisphere (2-clusters), and Quadrant (4-clusters).
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 Disabled and Enabled.
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

HPET is used to replace the 8254 Programmable Interval Timer. The options are Disabled
