Microprocessor Features
The Intel
®
Xeon™ microprocessors in your system provide NetBurst microarchitecture and
Hyper-Threading Technology to significantly increase microprocessor performance. Hyper-
Threading allows one physical microprocessor to appear as two logical processors to the
operating system and application programs. Hyper-Threading also allows each
microprocessor to simultaneously execute multiple tasks using shared hardware resources.
These new technology features in the microprocessor provide the following for
multithreaded tasks:
• Enhanced system performance
• Improved reaction and response time for the system
• Increased number of users that a system can support
• Increased number of transactions that can be executed simultaneously by the system
The CPU Information option in the System Setup program’s main screen displays
information about the different processors in the system (speed, cache size, and others.).
After the microprocessor information is displayed, you can enable or disable Hyper-
Threading by changing the setting of the Logical Processor option. (The default is
Enabled.)
You can find more information about Hyper-Threading Technology at developer.intel.com.
System Features
Your system contains the following new system features:
• Up to two Xeon microprocessors with a front-side bus speed of 533 MHz, an internal
operating speed of at least 2.0 GHz, and at least 512 KB of internal cache.
NOTE: Your system does not support microprocessors with different front-side buses.
• PC-2100 registered 266 MHz DDR SDRAM memory modules.
