[. . . ] So, whenever the sensor is triggered by lights or by the opening of the chassis, the system will beep to inform you. Please be informed that this useful function only applies to advanced chassis, you may purchase an extra sensor, attach it on your chassis, and make a good use of this function. Pin 1 Case Open Connector Sensor GND 1 60 AOpen i865 Family Motherboards STBY LED (Standby LED) and BOOT LED Online Manual Both STBY LED and BOOT LED are AOpen's considerate designs that aim at providing you friendly system information. This is a convenient indication for you to check the system power status in many circumstances such as power on/off, stand-by mode and RAM power status during Suspend to RAM mode. BOOT LED will keep blinking when you power the system on and when your system is under POST (Power-On Self Test). After POST diagnoses everything all right and finishes the booting, the LED will stay on otherwise it will remain flashing to warn you that mistakes have occurred during POST BOOT LED STBY LED Warning: Do not install or remove the DIMM module or others devices when the STBY LED lights on. 61 AOpen i865 Family Motherboards 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 62 AOpen i865 Family Motherboards 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. 63 AOpen i865 Family Motherboards 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, AOpen i865 Family motherboards implements 2200F capacitors, which is much larger than normal capacitor (1000 & 1500F) and it provides better stability for CPU power. 64 AOpen i865 Family Motherboards Online Manual PBE ­ Performance Boosting Engine (for AX4SG and AX4SPE series) Configuring Intel 865 chipset, the performance of this motherboard had been uplifted by implementing PBE Technology (Performance Boosting Engine). Acting as similar as PAT in uplifting the system performance, PBE enable users to optimize the accessing speed and quality between the CPU and Memory. Theoretically speaking, CPU must go through some standard paths to access memory. However, with an optimized path created, CPU may access memory through optimized path in a faster way. Therefore, PBE effectively shortened the distance between CPU and memory and thus increasing system performance as a matter of fact. To enable it, all you have to do is to go to BIOS screen, select Advanced Chipset Feature/Performance Boost Engine. Enable or Disabled PBE Technology Optimized Access Chipsets Memory Normal Access Dual Channel DDR Memory PBE item : Disabled (Default) Note: Enabling this feature will make maximum use of your RAM modules. Uneven quality RAM modules in the market may not able to withstand this kind of extreme usage and cause the instability of your system. ---- SilentTek Online Manual As the clock of CPU keeps rocketing higher and higher, it inevitably brings higher heat and system temperature in a relative way. The way we deal with this heat problem, however, is to spare no effort to add one fan after another to protect our pampered system, expecting these fans could cool down our machine as much as they could. But at the same time, we believe that same users are affected terribly by the irritating noises of these fans while working with their PC. As a matter of fact, we do not have to get our fans running at such a high speed in most cases; on the contrary, we discovered that having your fans running at appropriate time and speed not only reduces the noise, but also consumes the least power the system needs, so as to prevent over-wasting of energy resource. Today, AOpen Motherboard is honored to bring you a new overall solution, SilentTek, to make your system quiet. To collocate with hardware circuit, BIOS and the utility under Windows, "Hardware-Status SilentTek Monitoring", combined "Overheat Warning" and "Fan Speed Control" with user-friendly interfaces to provide you a perfect balance among performance and stability.
