1.3.4 ASUS Intelligent Overclocking features
AI NOS™ (Non-Delay Overclocking System)
The patented ASUS Non-delay Overclocking System™ (AI NOS™) technology
auto-detects the CPU loading and dynamically overclocks the CPU speed when
needed. Unlike other dynamic overclocking techniques, AI NOS™ reacts much
faster to satisfy your need for speed. See page 4-16 and 5-21 for details.
PEG Link Mode
This feature enhances your PCI Express graphics card performance. It allows the
motherboard to automatically adjust the PCI Express graphics link mode to the
correct frequency based on the system configuration. Four additional settings are
available for overclocking the PEG Link Mode. See page 4-22 for details.
Precision Tweaker
This feature allows you to fine tune the CPU/memory voltage and gradually
increase the memory Front Side Bus (FSB) and PCI Express frequency at 1MHz
increment to achieve maximum system performance. See page 4-16 to 4-18 for
details.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.
Due to the chipset behavior, AC power off is required before using C.P.R.
