1.3.2ASUS AI features
AI Quiet 
The ASUS AI Quiet function dynamically controls CPU speed and reduces temperature and fan speeds, thus minimizing noise and ensuring quiet operation. Enable ASUS Q-Fan and install an Intel¨ processor with Enhanced Intel SpeedStep Technology (EIST) to use this feature.
AI NOSª (Non-Delay Overclocking System) 
ASUS Non-delay Overclocking Systemª (NOS) is a technology that auto-detects the CPU loading and dynamically overclocks the CPU speed only when needed. 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.
AI NET 2 
(Deluxe model only)
AI NET 2 is a BIOS-based diagnostic tool that detects and reports Ethernet cable faults and shorts. With this utility, you can easily monitor the condition of the Ethernet cable(s) connected to the Marvell LAN (RJ-45) port. During the bootup process, AI NET 2 immediately diagnoses the LAN cable and reports shorts and faults up to 100 meters at 1 meter accuracy. See pages 2-25 and 5-11 for details.
AI Audio technology 
The motherboard supports 8-channel audio through the onboard Realtek¨ ALC850 CODEC with 16-bit DAC, a stereo 16-bit ADC, and an AC97 2.3 compatible multi-channel audio designed for PC multimedia systems. It also provides Jack-Sensing function, S/PDIF out support, interrupt capability and includes the Realtek¨ proprietary UAJ¨ (Universal Audio Jack) technology. See pages 2-24 and 5-12 for details.
Fanless Design
The ASUS fanless design allows multi-directional heat flow from major thermal sources in the motherboard to lower overall system temperature, resulting in quieter operation and longer system life.
