[. . . ] 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. 56 MX4GVR 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. 57 MX4GVR Resetable Fuse Online Manual Traditional motherboard uses fuses to prevent Keyboard and USB port from over-current or shortage. These fuses are soldered onboard that when it is broken (function to protect motherboard), user cannot replace them and result in malfunction of motherboard. With expensive Resetable Fuse, the motherboard can be resumed back to normal function even after the fuse had done its protection job. Resetable Fuse 58 MX4GVR 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, MX4GVR implements 2200F capacitors, which is much larger than normal capacitor (1000 & 1500f) and it provides better stability for CPU power. 59 MX4GVR Online Manual The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium III, or when overclocking). A typical CPU core voltage is 2. 0V, so a good design should control voltage between 1. 860V and 2. 140V. Below is a timing diagram captured by a Digital Storage Scope, it shows the voltage transient is only 143mv even when maximum 60A current is applied. Note: This diagram for example only, it may not be exactly the same as the motherboard you purchased. 60 MX4GVR 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 ) For high frequency Online Manual operation, especially when overclocking, layout is the most important factor to make sure both chipset and CPU are 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, we can avoid cross talk and frequency interference between each region's operations and condition. For example, the clock trace must be equal to length (not necessarily as short as possible) so that clock skew will be controlled within few a pico second 12 (1/10 Sec) Note: This diagram for example only, it may not look exactly the same as the motherboard you purchased. 61 MX4GVR Enlarged Aluminum Heatsink Online Manual Cool down CPU and Chipset are important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially when you are trying to over-clock the CPU. 62 MX4GVR Open Ju keBox Player Online Manual Here we are pleased to provide you a brand-new powerful interface--Open JukeBox.
