Hardware Setup CPU (Central Processing Unit) The mainboard supports 95W AMD ® Phenom/ Athlon 64/ Sempron processors in Socket AM3. The Socket AM3 offers easy CPU installation. W hen you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.
M S-7646M1 Mainboard CPU Installation Procedures for Socket AM3 1. Please turn off the power and unplug the power cord before installing the CPU. Open the lever Sliding the plate 90 degree 2. Pull the lever sideways away from the socket. Make sure that you raise the lever up to a 90-degree angle. Gold arrow 3. Look for the gold arrow on the CPU. T he gold arrow s hould point as shown in the picture. The CPU can only fit in the correct orientation.
Hardware Setup Installing CPU Cooler Set When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer. 1. Position the cooling set onto the 2. Then press down the other end of retention mechanism. Hook one end the clip to fasten the cooling set on of the clip to hook first.
M S-7646M1 Mainboard Memory These DIMM slots are intended for memory modules. DDR3 240 pins, 1.5V 56x2=112 pins 64x2=128 pins Dual-Channel Memory Population Rules In Dual-Channel mode, the memory modules can transmit and receive data with two data bus lines simultaneously. Enabling Dual-Channel mode can enhance the system performance. Please refer to the following illustrations for population rules under Dual-Channel mode.
Hardware Setup Installing Memory Modules 1. The memory module has only one notch on the center and will only fit in the right orientation. 2. Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot. The plastic clip at each side of the DIMM slot will automatically close when the memory module is properly seated.
