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 55 MX4G 2 2 0 0 F L o w E S R C a p a c i t or 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, MX4G implements 2200F capacitors, which is much larger than normal capacitor (1000 and 1500f) and it provides better stability for CPU power. 56 MX4G 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 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 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 pico second (1/1012 Sec) Note: This diagram for example only, it may not be exactly the same as this motherboard. 57 MX4G E nl a r g e d Al u m i n u m H e a t s i n k Online Manual Cool down CPU and Chipset is important for system reliability.
