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 the System Management chapter of the Maintenance and Service

Guide.

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 the System Management chapter of the Maintenance and Service Guide.

HP Cool Tools

An HP Workstation with Windows XP Professional includes additional software that is not installed

when you first start the workstation. Additionally, a number of preinstalled tools on the workstation can

enhance the workstation experience. To access or learn more about these applications:

1. Open the HP Cool Tools folder by selecting Start>All Programs>HP Cool Tools.

2. Select the HP Cool Tools icon on the desktop.

3. To learn more about these applications, select HP Cool Tools—Learn More.

To install or launch the applications, select the appropriate application.

NOTE: A preinstalled Windows Vista Business operating system does not contain an HP Cool Tools

icon, shortcut, or folder, but several of the tool programs are included, such as Performance Tuning

Framework.
