Hyper-Threading Hyper-Threading is an Intel® technology that can enhance overall computer 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 can benefit from Hyper-Threading, 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 about using Hyper-Threading with your software. 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 more information on Hyper-Threading, search the Knowledge Base on the Dell Support website at support.dell.com.
