If you use the ratio value to time the CPU frequency, it will be equal to the core
speed of the installed processor.
Ratio Actual Value
This is a read-only item, which displays the ratio actual value of this
motherboard.
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.
Intel (R) Virtualization tech.
When this option is set to [Enabled], a VIMM (Virtual Machine Architecture)
can utilize the additional hardware capabilities provided by Vanderpool
Technology. This option will be hidden if the installed CPU does not support
Intel (R) Virtualization Technology.
CPU Thermal Throttling
You may select [Enabled] to enable P4 CPU internal thermal control mecha-
nism to keep the CPU from overheated.
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
Protection” 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.
Enhance Halt State
All processors support the Halt State (C1). The C1 state is supported
through the native processor instructions HLT and MWAIT and requires no
hardware support from the chipset. In the C1 power state, the processor
maintains the context of the system caches.
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 [Enabled] 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.
Intel (R) SpeedStep(tm) tech.
Intel (R) SpeedStep(tm) tech. is Intel’s new power saving technology. Proces-
sor can switch between multiple frequency and voltage points to enable
power savings. If you select [Auto], you need to set the “Power Schemes”
as “Portable/Laptop” to enable this function.
