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 specically optimized for HTT.
Use the Computer Setup (F10) Utility to enable HTT.
Go to http://www.hp.com/go/quickspecs to determine if your CPU 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 CPU to run at frequencies above the normal frequency. When all CPU cores are not
necessary for the workload, inactive cores are turned o 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 CPU supports Turbo Boost.
BIOS ROM
The BIOS ROM is a collection of machine language applications stored as rmware 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.
