[. . . ] However, the new generation CPU uses different voltage that has regulator to transfer 12V to CPU voltage (for example, 2. 0V). This motherboard is with switching regulator onboard supports CPU over-current protection; in conjunction with 3. 3V/5V/12V power supply provide the full line over-current protection. 5V (Protected by power supply) ATX Switching Power Supply 12V (Protected by power supply) 3. 3V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason. We cannot guaranty the protection circuit will always work perfectly. 50 MX46L Hardware Monitoring Online Manual This motherboard implements a hardware monitoring system. 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. 51 MX46L Resettable 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 Resettable Fuse, the motherboard can be resumed back to normal function after the fuse had done its protection job. Resettable Fuse 52 MX46L 1500F 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, MX46L implements 1500F capacitors, which is much larger than normal capacitor (1000F) and it provides better stability for CPU power. 53 MX46L Layout (Frequency Isolation Wall) 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 our 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 within few a 12 pico second (1/10 Sec) Note: This diagram for example only, it may not be exactly the same as this motherboard. 54 MX46L Pure Aluminum Heatsink Online Manual Cool down CPU and Chipset is important for system reliability. Aluminum heat sink provides better heat consumption especially when you are trying to over clocking the CPU. 55 MX46L Online Manual Driver and Utility There are motherboard drivers and utilities included in AOpen Bonus CD disc. You don't need to install all of them in order to boot your system. But after you finish the hardware installation, you have to install your operation system first (such as Windows 98) before you can install any drivers or utilities.
