"*" HT functionality requirement content :

Enabling the functionality of Hyper-Threading Technology for your computer system requires all

of the following platform components:

®

- CPU: An Intel

Pentium 4 Processor with HT Technology

®

- Chipset: An Intel

Chipset that supports HT Technology

- BIOS: A BIOS that supports HT Technology and has it enabled

- OS: An operation system that has optimizations for HT Technology

Please set the CPU host frequency in accordance with your processor's specifications.

We don't recommend you to set the system bus frequency over the CPU's specification because

these specific bus frequencies are not the standard specifications for CPU, chipset and most of the

peripherals. Whether your system can run under these specific bus frequencies properly will

depend on your hardware configurations, including CPU, Chipsets, SDRAM, Cards etc.
