Hyperthreading and Multi-Core Technology

Hyperthreading is an Intel technology that can enhance overall computer performance by allowing one physical processor to function as two logical processors that are capable of performing certain tasks simultaneously. Multi- core processors contain two or more physical computational units inside a single CPU package, thereby increasing computing efficiency and multi- tasking ability. Intel has implemented this technology in its Dual-Core and Quad-Core processors. These processors have two and four computational units respectively. It is recommended that you use the Microsoft Windows XP Service Pack 1 (SP1) or higher or Windows Vista operating systems which are optimized to take advantage of these technologies.

While many programs can benefit from hyperthreading and multi-core technology, some programs may have not been optimized for them and may require an update from the software manufacturer. Contact the software manufacturer for updates and information about using hyperthreading or multi-core technology with your software. To determine if your computer is using hyperthreading technology, check the system setup option for hyperthreading under the Performance tab (see "System Setup" on page 290).

About RAID Configurations

This section provides an overview of the RAID configuration that you might have selected when you purchased your computer. While there are many RAID configurations available in the computer industry for different types of uses, Dell offers RAID level 0, RAID level 1, or RAID level 5 on your Dell Precision computer.

A RAID level 0 configuration is recommended for high-performance programs, and a RAID level 1 configuration is recommended for users that desire a high level of data integrity. A RAID level 5 configuration provides for both data integrity and high performance. RAID levels do not represent a hierarchy. A RAID level 5 configuration is not inherently better or worse than a RAID level 0 configuration.

The Intel RAID controller on your computer can only create a RAID level 0 configuration using two or three physical drives. If a third drive is present, then that drive can be made part of a RAID level 0 configuration using the
