[. . . ] However, the new generation CPU uses different voltage with a regulator to transfer 12V to CPU voltage (for example, 2. 0V), and thus makes 5V over current protection useless. This motherboard is with switching regulator onboard supporting CPU over-current protection; in conjunction with 3. 3V/5V/12V power supply provide the full line over-current protection. 3. 3V (Protected by power supply) ATX Switching Power Supply 5V (Protected by power supply) 12V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit and tried to prevent any human operating mistake, certain risks might still happen when CPU, memory, HDD or add-on cards installed on this motherboard is damaged due to component failure, human operating error or other unknown natural reasons. AOpen cannot guarantee that the protection circuit will always work perfectly. 53 MX46-533V / MX46-533 Max Hardware Monitoring Online Manual This motherboard implements a hardware monitoring system. As you turn on your system, this smart design will monitor your system's working voltage, fan status and CPU temperature. If any of those systems' status goes wrong, there will be an alarm through the chassis external speaker or buzzer of motherboard (if having this function and enabled) to warn the user. Fan Fan Speed CPU CPU Temperature CPU Voltage Detection Circuit AOpen H/W Monitoring Utility Power System Voltage 54 MX46-533V / MX46-533 Max Resettable 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 Resettable Fuse, the motherboard can be resumed back to normal function even after the fuse had done its protection job. Resettable Fuse 55 MX46-533V / MX46-533 Max Low ESR Capacitor 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, MX46-533V / MX46-533 Max implements 2200F capacitors, which is much larger than normal capacitor (1000 & 1500f) and it provides better stability for CPU power. 56 MX46-533V / MX46-533 Max 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. 57 MX46-533V / MX46-533 Max Layout (Frequency Isolation Wall) For high Online Manual frequency 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 (1/10 Sec) 12 Note: This diagram for example only, it may not look exactly the same as the motherboard you purchased. 58 MX46-533V / MX46-533 Max 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. 59 MX46-533V / MX46-533 Max Online Manual Driver and Utility There are motherboard drivers and utilities in AOpen Bonus CD You don't need to install all of them to boot your system. finish the hardware installation, you have to install your operation system first (such as Windows 98) before you install any drivers or utilities. Please refer to your operation system's installation guide. Note: Please follow recommended procedure to install Windows 2000 and Windows 98. 60 MX46-533V / MX46-533 Max Auto-run Menu from Bonus CD Online Manual You can use the auto-run menu of Bonus CD. Choose the utility and driver and select model name. 61 MX46-533V / MX46-533 Max Install IDE Driver To use IDE devices you have to install IDE driver from Bonus Pack CD. Online Manual 62 MX46-533V / MX46-533 Max Installing AGP Driver You can find AGP driver from the Bonus Pack CD auto-run menu. Online Manual 63 MX46-533V / MX46-533 Max Installing VGA Driver Online Manual SiS 651 supports VGA on this motherboard. You can install VGA driver form the Bonus Pack CD. 64 MX46-533V / MX46-533 Max Install USB2. 0 Driver In Bonus Pack CD, you can install USB2. 0 driver from the following screen. Online Manual 65 MX46-533V / MX46-533 Max Installing LAN Driver Online Manual You can download LAN Driver from the Bonus Pack CD and install it under Windows 95 (Golden version), Win95A, OSR2, Windows 98/98 SE, Windows 2000, Windows ME, Windows NT v4. 0 driver for Realtek RTL8201 PCI Fast Ethernet adapter. [Windows 95 (Golden version), Win95A and OSR2] Installing driver procedure on Microsoft Windows 95 : ----------------------------------------------------1. Ask you to select which driver you want to install, select "Driver from disk provided by hardware manufacturer".
