Optimizing Performance

Hyper-Threading

Hyper-Threading is an Intel
allowing one physical processor to function as two logical processors, capable of performing certain
tasks simultaneously. It is recommended that you use the Microsoft
(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 if your computer is using Hyper-Threading technology:
1 Click the Start button, right-click My Computer, and then click Properties.
2 Click Hardware, then 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 "Entering System Setup" on page 127. For more information on Hyper-Threading,
search the Knowledge Base on the Dell Support website at support.dell.com.

About Your RAID Configuration

This section provides an overview of the RAID configuration you may have selected when you
purchased your computer. There are several RAID configurations are available in the computer
industry for different types of uses. Your Dell Dimension™ computer supports RAID level 0 and
RAID level 1. A RAID level 0 configuration is recommended for high-performance programs or
gaming, and a RAID level 1 configuration is recommended for users that desire a high level of data
integrity, such as that required in digital photography and audio.
NOTE:
RAID levels do not represent a hierarchy. A RAID level 1 configuration is not inherently better or worse
than a RAID level 0 configuration.
The drives in a RAID configuration should be the same size in order to ensure that the larger drive
does not contain unallocated (and therefore unusable) space.
