NOTE: For more information on power management, see your operating system documentation. 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. Multicore processors contain two or more physical computational units inside a single CPU package, thereby increasing computing efficiency and multitasking 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 NOTE: RAID levels 5 and 10 are only available via an optional PCI Express RAID controller card. NOTE: RAID for SATA 1.0 is not supported. This section provides an overview of the RAID configuration that you might have selected when you purchased your computer. Although there are several RAID configurations available in the computer industry for different types of uses, Dell offers RAID level 0, RAID level 1, or, with an optional PCI Express RAID controller, RAID level 5 or RAID level 10 on your Dell Precision computer. A RAID level 0 configuration is recommended for highperformance programs, and a RAID level 1 configuration is recommended for users that desire a high level of data integrity. A RAID level 5 or a RAID level 10 configuration provides for both data integrity and higher access speeds. Advanced Features 39
