Ratio Actual Value
This is a read-only item, which displays the ratio actual value of this
motherboard.
CPU Thermal Throttling
You may select [Enabled] to enable P4 CPU internal thermal control mecha-
nism to keep the CPU from overheated.
Hyper Threading Technology
To enable this feature, it requires a computer system with an Intel Pentium
®
4
processor that supports Hyper-Threading technology and an operating sys-
tem that includes optimization for this technology, such as Microsoft
®
Win-
dows
®
XP. Set to [Auto] if using Microsoft
®
Windows
®
XP, or Linux kernel
version 2.4.18 or higher. This option will be hidden if the installed CPU does
not support Hyper-Threading technology.

Max CPUID Value Limit
For Prescott CPU only, some OSes (ex. NT4.0) cannot handle the function
with disable. This should be enabled in order to boot legacy OSes that cannot
support CPUs with extended CPUID functions.
No-Excute Memory Protection
No-Execution (NX) Memory Protection Technology is an enhancement to the IA-
32 Intel Architecture. An IA-32 processor with “No Execute (NX) Memory Pro
tection” can prevent data pages from being used by malicious software to
execute code. This option will be hidden if the current CPU does not support No-
Excute Memory Protection.
Bypass Access
This technology can provide users with the function of increasing the sys-
tem performance. The default value is [Off]. It will only work when you use
FSB800 CPU and DDR400 DRAM at the same time; otherwise, this option will
be hidden.
