Hyper-Threading
Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical processor to function as two logical
processors, capable of performing certain tasks simultaneously. It is recommended that you use the Microsoft® Windows® XP Service Pack 1 (SP1) or higher
operating system because Windows XP is optimized to take advantage of Hyper-Threading technology. While many programs can benefit from Hyper-

manufacturer for updates and information about using Hyper-Threading with your software.
