HP Z400 User Manual

Hyper-threading
This HP workstation supports Hyper-threading.
Hyper-Threading Technology (HTT), is an Intel-proprietary technology used to provide process
parallelization. The operating system treats a processor with Hyper-Threading enabled as two
processors instead of one. This improves performance under certain workloads by getting useful work
from parts of the processor that would otherwise remain idle. Hyper-threading relies on support from
the operating system as well as the CPU.
To implement hyper-threading, see
The Computer Setup (F10) Utility on page 31.
SATA Power Management
SATA Power Management enables or disables SATA bus and/or device power management.
Intel Turbo Boost Technology
The HP Z Workstation series supports Intel® Turbo Boost Technology.
When the workload does not require all CPU cores, this feature diverts power from inactive cores to
active cores, increasing their performance. This lets the CPU run at a higher than normal rate.
Use the workstation BIOS to enable, enhance, or disable Turbo Boost. For instructions on setting BIOS
features, see
The Computer Setup (F10) Utility on page 31.
HP Cool Tools
An HP workstation with Windows 7 or Windows Vista includes additional software not installed when
you first start the workstation. To access or learn more about these additional preinstalled tools on the
workstation that can enhance the workstation experience:
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.
4. To install or launch the applications, select the appropriate application.
NOTE: A preinstalled Windows Vista Business operating system does not contain a Cool Tools icon,
shortcut or folder, but several of the tool programs are included, such as Performance Tuning
Framework.
