Hyper-Threading Technology
Hyper-Threading Technology is a high performance technology, developed by Intel®, that allows a single
processor to execute multiple threads of instructions simultaneously. Hyper-Threading Technology enables
the processor to utilize its execution resources more efficiently, delivering performance increases and
improving user productivity. Not all systems benefit from the Hyper-Threading Technology.
To see if Hyper-Threading Technology can benefit you, test your system by turning the feature on using
the Computer Setup (F10) system utility. To do this, run F10 Setup during boot up and select Advanced >
Device Options > Hyper-Threading, and enable the Hyper-Threading Technology.
Note the following:
If your workstation does not support Hyper-Threading Technology, the Hyper-Threading menu item
will not be available on the Computer Setup menu.
The Hyper-Threading Technology is recommended for use with Microsoft® Windows® XP systems.
This technology is detected by the system and is turned on in the operating system after it is enabled in
the system BIOS.
Hyper-Threading is not recommended for use with Windows 2000-based workstations.
The Hyper-Threading Technology is compatible with Linux-based systems. An SMP kernel must be
installed on your system before this technology can be enabled.
