PCIE Clock Operation Mode
When [Sync. mode] is selected, the PCIE clock is synchronous with CPU
host frequency. When [Async. mode] is selected, the PCIE clock is fixed at
100MHz.
Ratio Status
This is a read-only item, which displays whether the ratio status of this
motherboard is "Locked" or "Unlocked". If it shows "Unlocked", you will find
an item Ratio Setting appears to allow you changing the ratio value of this
motherboard. If it shows "Locked", then the item Ratio Setting will be
hidden. 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.
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.
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 VMM (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.
Hyper Threading Technology
To enable this feature, it requires a computer system with an Intel Pentium
processor that supports Hyper-Threading technology and an operating sys-
tem that includes optimization for this technology, such as Microsoft
dows
