Hyper-Threading Technology (HTT)
This computer supports HTT, an Intel-proprietary technology that improves processor performance through
parallelization of computations (doing multiple tasks at once).
The operating system treats an HTT-enabled processor as two virtual processors, and shares the workload
between them when possible. This feature requires that the operating system support multiple processors
and be specifically optimized for HTT.
Use Computer Setup (F10) Utility to enable HTT.

SATA Power Management
SATA Power Management enables or disables SATA bus and/or device power management.
Intel Turbo Boost Technology
Your workstation supports Intel® Turbo Boost Technology.
This feature enables the CPU to run at a higher than normal rate. When all CPU cores are not necessary for the
workload, inactive cores are turned off and power is diverted to the active cores to increase their
performance.
Turbo Boost is enabled and disabled with Computer Setup (F10) Utility.

Non-Uniform Memory Access (NUMA)
Non-uniform memory access (NUMA) is available on some workstations. NUMA can improve memory
bandwidth and latency for multi-process or multi-threaded applications or workloads. Observed performance
improvements depend on the operating system, customer workload, system configuration, and the degree to
which the applications used are designed to be NUMA-aware/efficient.
NUMA requires that both processor sockets be populated. Installed memory should be balanced between both
processors for maximum performance.
NUMA is enabled if Memory Node Interleave is disabled in the system BIOS. To do this, press
startup to enter Computer Setup (F10) Utility. Select Advanced > Chipset/Memory. Use the arrow keys to set
Memory Node Interleave to Disable. Press
Exit. Your change takes effect when the computer restarts.
BIOS ROM
The BIOS ROM is a collection of machine language applications stored as firmware in ROM. It includes
functions such as Power-On Self-Test (POST), PCI device initialization, Plug and Play support, power
management, and Computer Setup (F10) Utility.
