Hyper-Threading
Hyper-Threading is an Intel
®
technology that can enhance overall 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 Windows XP
operating system because Windows XP is optimized to take advantage of Hyper-Threading
technology. While many programs can benefit from Hyper-Threading technology, 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
on using your software with Hyper-Threading.
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 system setup. For more information on
Hyper-Threading, search the Knowledge Base on the Dell Support website at

IEEE 1394
IEEE 1394 is a digital interface that can move large amounts of data between computers
and peripheral devices. IEEE 1394 is ideal for use with multimedia devices because it
speeds the transfer of data and large files, which enables a computer to connect directly to
devices such as digital video cameras.
The Dell Precision 650 computer provides a standard IEEE 1394 connector on both the
front and back panels (see "About Your Computer—Dell Precision 650").
U320 SCSI Controller
The U320 SCSI controller is PCI-X based and operates in a low voltage differential (LVD)
mode while running at U320 (320 MBps) speeds. The bus is backward compatible and can
run at U160 (160 MBps), Ultra2 (80 MBps), Ultra (40 MBps) speeds.
