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
later 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 whether 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 Processors . If Hyper-Threading is
enabled, the processor is listed twice.
You can enable or disable Hyper-Threading through system setup. For more information on accessing
system setup, see "System Setup" on page 113. For more information on Hyper-Threading, search the
Knowledge Base on the Dell Support website at

About RAID Configurations
This section provides an overview of the RAID configuration that you might have selected when you
purchased your computer. Of the RAID configurations available in the computer industry for different
uses, Dell offers RAID level 1 on your computer. A RAID level 1 configuration is recommended for users
that desire a high level of data integrity.
The Intel RAID controller on your computer can only create a RAID level configuration using two
physical drives. The drives should be the same size to ensure that the larger drive does not contain
unallocated (and therefore unusable) space.
NOTE:
If you purchased your Dell computer with RAID, your computer has been configured with two hard drives
that are the same size.
