AX37D Plus / AX37D Pro Online Manual O v e r - c ur r e n t P r o t e c t i o n It is very popular that the Over Current Protection was implemented on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU uses different voltages that has regulator to transfer 5V to CPU voltage (for example, 2.0V), and thus makes 5V over current protection useless. This motherboard is equipped with switching regulator onboard which supports CPU over-current protection; in conjunction with 3.
AX37D Plus / AX37D Pro Online Manual H a r d w a r e M o ni t o r i n g 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 go wrong, there will be an alarm through the AOpen Hardware Monitoring Utility to warn the user.
AX37D Plus / AX37D Pro Online Manual R e se t ta b l e F u s e Traditional motherboard has fuse for Keyboard and USB port to prevent over-current or shortage. These fuses are soldered onboard that user cannot replace it when it is damaged (did the job to protect motherboard), and the motherboard remains malfunction. With expensive Resettable Fuse, the motherboard can resume back to normal function after fuse had done its protection job.
AX37D Plus / AX37D Pro Online Manual Year 2000 (Y2K) Y2K is basically a problem of the identification of year code. To save storage space, traditional software uses only two digits for year identification. For example, 98 for 1998 and 99 for 1999, but 00 will be confused with 1900 and 2000. There is an RTC circuit (Real Time Clock) in conjunction with 128 bytes of CMOS RAM data in the chipset of the motherboard. The RTC has only two digits and the CMOS has another 2 digits.
AX37D Plus / AX37D Pro Online Manual follow the rule to get date/time information. There will be no Y2K problem (such as NSTL’s test program). But unfortunately again, we found some test programs (such as Checkit 98) accesses RTC/CMOS directly. This motherboard has hardware Y2K checking and protection that ensures risk free operation.
AX37D Plus / AX37D Pro Online Manual 22 0 0μ f L o w E S R C a p ac i t o r 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 2200μf condensers, which is much larger than normal condenser (1000 or 1500μf) and it provides better stability for CPU power.
AX37D Plus / AX37D Pro 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. 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 18A current is applied.
AX37D Plus / AX37D Pro Online Manual Layout (Frequency Isolation Wall) For high frequency operation, especially overclocking, layout is the most important factor to make sure chipset and CPU working in stable condition.
