Intel
Your Dimension™ XPS computer is equipped with the Intel
Performance Acceleration Technology (PAT). PAT is designed to optimize performance by
reducing the latency between DDR 400 memory and 800 front-side bus processors, and
helps provide high performance to meet the requirements for today's demanding software.
DDR Memory and Processor Front-Side Bus
The performance of your computer's DDR memory depends on the type of memory
installed and the clock speed of your processor. The following table indicates the memory
performance resulting from different combinations of memory and front-side bus:
Memory type
DDR 400 (PC3200)
DDR 333 (PC2700)
For information on installing memory, see page 86. For information on the type of memory
supported by your computer, see "Memory" on page 120.
Hyper-Threading
NOTE: Hyper-Threading is supported only on computers that have 3.06-GHz (or higher)
microprocessors installed.
Hyper-Threading is an Intel
by allowing one physical microprocessor to function as two logical microprocessors, capable
of performing certain tasks simultaneously. It is recommended that you use the Microsoft
Windows
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.
