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.)
System Memory Features
Your system features redundant memory, which provides the system with a failover memory
bank when an active memory bank has excessive single-bit errors. This failover occurs
without the need to halt or restart the system. You can enable this feature in the System
Setup program. For more information about the System Setup program, see your User's
Guide.
To enable the Redundant Memory option in the System Setup program, all memory slots in
the system must be populated, and all memory modules must be of the same type and size.
The redundant memory options vary according to the number of populated memory banks
and whether identical memory modules are installed in each bank:
• Disabled — One or more banks are not populated, or not all memory modules are of
the same type and size.
• Disabled and Spare Bank Enabled — All three memory banks are populated with
memory modules of the same size and type.
