Hyper-Threading
Hyper-Threading is an Intel® technology that can enhance overall
performance by allowing one physical microprocessor to function as two
logical microprocessors, capable of performing certain tasks simultaneously.
It is recommended that you use the Microsoft® Windows® XP operating
system because Windows XP is optimized to take advantage of Hyper-
Threading technology. While many programs will benefit from Hyper-
Threading technology, some programs have not been optimized for Hyper-
Threading, and may require an update from the software manufacturer.
Contact the software manufacturer for updates and information on using
your software with Hyper-Threading.
HINT: Hyper-Threading
is supported only on
computers that have 3.06-
GHz microprocessors (or
higher) installed.
To determine if your computer is using Hyper-Threading technology:
1
Click the Start button, right-click My Computer , and then click
Properties .
2
Click Hardware and click Device Manager .
3
In the Device Manager window, click the plus (+) sign next to the
processor type. If Hyper-Threading is enabled, the processor is listed
twice.
You can enable or disable Hyper-Threading through the system setup
program. For information on accessing the system setup program, see
page 110. For more information on Hyper-Threading, search the Knowledge
Base on the Dell Support website at
