[. . . ] Please note that if you install a AGP card with 3. 3V, which is not supported, the AGP LED on the motherboard will light up to warn you the possible damage of the exceeding voltage. You may contact your AGP card vendor for further support. AGP LED Warning: It is strongly recommended not to install a 3. 3V AGP card, which is not supported. When you do so, the AGP LED on the motherboard will light up to warn you the possible damage. 57 AK77-600GN Bat te ry- less a nd Long Lif e Des ign H TU TH Online Manual This Motherboard implements Flash ROMU and a special circuit that allows you to save your current CPU and CMOS Setup configurations without using the battery. The RTC (real time clock) can also keep running as long as the power cord is plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from Flash ROM and the system will recover as usual. ATX Stand-by Power Battery Auto Switch Auto switching to ATX standby power RTC (Real Time Clock) 00:00:00 as long as AC power line is plugged. This smart design can increases battery life if you still had battery plugged on motherboard. Flash ROM CMOS Backup by EEPROM 58 AK77-600GN 330 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, this motherboard implements 3300F capacitor, which is much larger than normal capacitor (1000 or 1500F) and it provides better stability for CPU power. 59 AK77-600GN Online Manual The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the Pentium IV, or when overclocking). A typical CPU core voltage is 2. 0V, so a good design should control voltage between 1. 860V and 2. 140V. That is, the transient must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope, it shows the voltage transient is only 143mv even when maximum 60 current is applied. Note: This diagram for example only; it may not exactly be the same motherboard. 60 AK77-600GN A O C o n f i g Ut i li ty AOpen Online Manual 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. 61 AK77-600GN 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 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. 62 AK77-600GN EzClock Online Manual Have you ever thought how great it would be if you can adjust the frequency setting on your motherboard under Windows environment and be a real master of your system?Everybody knows that the ratio and frequency setting are key factors to influence the system performance; however, it's absolutely not an easy task for an amateur to adjust the setting value.
