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

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
