1.8 Jumper Settings This section provides instructions on how to configure your motherboard by setting the jumpers. It also includes the motherboard default settings and your options for each jumper. 1.8.1 How to set jumpers You can configure your motherboard to match the needs of your application by setting the jumpers. A jumper is a metal bridge that closes an electrical circuit.
1.8.3 Watchdog timer output (JWDT1) The AIMB-781 contains a watchdog timer that will reset the CPU. This feature means the AIMB-781 will recover from a software failure or an EMI problem. The JWDT1 jumper settings control the outcome of what the computer will do in the event the watchdog timer is tripped. Table 1.
AIMB-781 has four 240-pin memory sockets for DDR3 1066/1333 MHz memory modules with maximum capacity of 16GB (Maximum 4GB for each DIMM). AIMB781QG2 and AIMB-781QVG SKU only support non-ECC DDR3 memory modules. Please note that both versions AIMB-781 do NOT support registered DIMMs (RDIMMs). Note! 1.10 Memory Installation Procedures To install DIMMs, first make sure the two handles of the DIMM socket are in the “open” position. i.e. The handles lean outward.
