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 CMOS Setting appears to allow you changing the ratio value
of this motherboard. If it shows "Locked", then the item Ratio CMOS Set-
ting 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

dows ® XP. Set to [Auto] if using Microsoft
version 2.4.18 or higher. This option will be hidden if the installed CPU does
not support Hyper-Threading technology.
No-Excute Memory Protection: No-Execution (NX) Memory Protection Tech
nology is an enhancement to the IA-32 Intel Architecture. An IA-32 proces
sor 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.
