[. . . ] It is recommended to use the cap tab to handle and avoid kicking off the PnP cap. This cap must be placed if returning the motherboard for after service. Secure load lever with load plate tab under retention tab of load lever. For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink. Below is an example to illustrate the installation of the heatsink for 775-LAND CPU. Rotate the fastener clockwise, then press down on fastener caps with thumb to install and lock. If you press down the fasteners without rotating them clockwise, the heatsink cannot be secured on the motherboard. Secure excess cable with tie-wrap to ensure cable does not interfere with fan operation or contact other components. This motherboard provides two 184-pin DDR (Double Data Rate) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install two identical (the same brand, speed, size and chip-type) memory modules in the DDR DIMM slots to activate Dual Channel Memory Technology. If you install only one memory module or two non-identical memory modules, it is unable to activate the Dual Channel Memory Technology. Please make sure to disconnect power supply before adding or removing DIMMs or the system components. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation. Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated. There are 3 PCI slots, 1 AGP slot, and 1 AMR slot on this motherboard. PCI slots: The PCI slots are used to install expansion cards that have the 32-bit PCI interface. The ASRock AGP slot has a special design of clasp that can securely fasten the inserted graphics card. AMR slot: AMR slot is used to insert an ASRock MR card (optional) with v. Before installing the expansion card, please make sure that the power supply is switched off or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation. Remove the system unit cover (if your motherboard is already installed in a chassis). Align the card connector with the slot and press firmly until the card is completely seated on the slot. [. . . ] Please connect the CPU fan cable to this connector and match the black wire to the ground pin. Though this motherboard provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin CPU fan still can work successfully even without the fan speed control function. If you plan to connect the 3-Pin CPU fan to the CPU fan connector on this motherboard, please connect it to Pin 1-3. Please note that it is necessary to connect a power supply with ATX 12V plug to this connector so that it can provides sufficient power. [. . . ]
