As you turn on your system, this smart design will continue to monitor your system's working voltage, fan status and CPU temperature. If any of these systems' status goes wrong, there will be an alarm through the chassis external speaker or buzzer of motherboard (if existed) to warn the user. Fan Fan Speed Detection Circuit AOpen H/W Monitoring Utility CPU CPU Temperature CPU Voltage Power System Voltage 61 AX4G / AX4G-N A O C o n f i g Ut i li ty Online Manual AOpen always dedicated to provide users a much friendlier computer environment. We now bring you a comprehensive system detective utility. AOconfig is a Windows based utility with user-friendly interface that allows users to obtain information of the operation system and hardware such as motherboard, CPU, memory, PCI devices and IDE devices. The powerful utility also displays the version of BIOS and firmware for your convenience of maintenance. Moreover, AOconfig allows users to save information in *. BMP or *. TXT format which users may collect the system information in detail and send them to AOpen directly for technical support or further diagnosis of system problem. 1. The system page shows the detail information of the motherboard, the operating system, the processor, and BIOS version. 2. The PCI device page shows the configurations of all PCI devices installed on your motherboard. 62 AX4G / AX4G-N 3. This page presents the IDE devices information, such as the serial number, the manufacturer, the firmware version, and capacity. Online Manual 4. From this page, users may obtain the technical support information of AOpen. Moreover, detailed information could be saved in . bmp or . txt format. NOTE: AOconfig can be used in Windows 98SE/ME, NT4. 0/2000, or even the latest Windows XP. Please be informed that AOconfig can only be operated in a system equipped with an AOpen motherboard. Meanwhile, all applications must be closed before starting AOconfig. 63 AX4G / AX4G-N Resetable Fuse Online Manual Traditional motherboard has fuse for Keyboard and USB port to prevent over-current or shortage. These fuses are soldered onboard that when it is broken (function as protecting the motherboard), user still cannot replace it and the motherboard is still malfunctioning. With expensive Resetable Fuse, the motherboard can be resumed back to normal function after the fuse had done its protection job. Resetable Fuse 64 AX4G / AX4G-N 220 0 F L o w ES R Ca p a c it o r Online Manual The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation. Not only that, AX4G / AX4G-N implements 2200F capacitors, which is much larger than normal capacitor (1000 and 1500f) and it provides better stability for CPU power. 65 AX4G / AX4G-N L a y o u t ( F r e q u e n c y I s o l a t i o n Wa l l ) Online Manual For high frequency operation, especially overclocking, layout is the most important factor to make sure chipset and CPU working in stable condition. The layout of this motherboard implements AOpen's unique design called " Frequency Isolation Wall". Separating each critical portion of motherboard into regions where each region operates in a same or similar frequency range to avoid cross talk and frequency interference between each region's operations and condition. The trace length and route must be calculated carefully. For example, the clock trace must be equal length (not necessarily as short as possible) so that clock skew will be controlled 12 within few a pico second (1/10 Sec) Note: This diagram for example only, it may not be exactly the same as this motherboard. 66 AX4G / AX4G-N Enlarged Aluminum Heatsink Online Manual Cool down CPU and Chipset is important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially when you are trying to over clocking the CPU. 67 AX4G / AX4G-N Online Manual D r iv e r a n d Ut i li t y There are motherboard drivers and utilities included in AOpen Bonus CD disc. [. . . ] You can find this bar code label on the outside packing, on ISA/CPU slot or on component side of PCB. For example: Part No. Serial No. Part No. P/N: 91. 88110. 201 is part number, S/N: 91949378KN73 is serial number. 114 AX4G / AX4G-N Mo de l na me a n d B IO S v ers i on Online Manual Model name and BIOS version can be found on upper left corner of first boot screen (POST screen).
