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 the Computer Setup (F10) Utility to enable HTT. Go to http://www.hp.com/go/quickspecs to determine if your processor supports HTT. 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. This feature enables the processor to run at frequencies above the normal frequency. When all processor 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 the Computer Setup (F10) Utility. Go to http://www.hp.com/go/quickspecs to determine if your processor supports Turbo Boost. 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. Go to http://www.hp.com/go/quickspecs to review the latest BIOS ROM specifications. 24 Chapter 2 System management

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 the Computer Setup (F10) Utility to enable HTT.
Go to
go/quickspecs
to determine if your processor supports HTT.
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.
This feature enables the processor to run at frequencies above the normal frequency. When all processor
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 the Computer Setup (F10) Utility.
Go to
go/quickspecs
to determine if your processor supports Turbo Boost.
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.
