Hyper-threading

This workstation supports Hyper-Threading Technology (HTT) which is an Intel-proprietary technology
used to provide process parallelization. The technology improves processor performance under certain
workloads by providing useful work for execution units that would otherwise be idle. A processor with
Hyper-Threading enabled is treated by the operating system as two processors instead of one. Hyper-
threading relies on support in the operating system as well as the CPU.
To implement hyper-threading, see

SATA Power Management

The SATA power management feature allows a SATA host or a device to request that the SATA power
bus be put into a reduced power state after a period of inactivity. The responding host or device can
accept or decline the request. The SATA power management feature is enabled in the F10 Computer
Setup (F10) Utility for use with devices that have this capability. When enabled, this feature helps reduce
power consumption and extend battery life in the HP workstation.

Intel Turbo Boost Technology

This workstation supports Intel® Turbo Boost technology which 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 efficiency.
You can enable and disable Turbo Boost in the workstation BIOS menu. For instructions on setting BIOS
features, see
