STEP 1: Install the AMD 940-pin AM2 CPU into AM2CPU Board, then install the CPU fan and heatsink into AM2CPU Board, and connect the CPU fan to the CPU fan connector (CPU_FAN1). NOTE: Though AM2CPU Board 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 use a 4-Pin CPU fan on AM2CPU Board, the fan speed control function needs to depend on the motherboard support. Pin1-3 Connected 3-Pin Fan Installation 4-Pin Fan Installation STEP 2: Install DRAM into AM2CPU Board. STEP 3: If necessary, remove the CPU heatsink retention module from the ASRock motherboard that you are going to install AM2CPU Board into. NOTE: Whether or not to remove the CPU heatsink retention module from the ASRock motherboard depends on the type of CPU fan installed on AM2CPU Board. STEP 3-1: Place the ASRock motherboard with its backside up. STEP 3-2: Use a flathead screwdriver to press down the WHITE fastener of the CPU heatsink retention module through the hole. STEP 3-3: Use a pair of pliers to clutch the BLACK supporting part of the CPU heatsink retention module, then press it down through the hole. STEP 3-4: Place the ASRock motherboard with its backside down, then remove the loosened CPU heatsink retention module from the motherboard. STEP 3-4 STEP 3-2 STEP 3-1 STEP 3-3 STEP 4: Adjust the jumper settings on ASRock motherboard to fit with the requirement for AMD 940-pin AM2 CPU installation.
