IMB-G41A Micro-ATX Motherboard 4.1 Anti-static Precautions WARNING: Failure to take ESD precautions during the installation of the IMB-G41A may result in permanent damage to the IMB-G41A and severe injury to the user. Electrostatic discharge (ESD) can cause serious damage to electronic components, including the IMB-G41A. Dry climates are especially susceptible to ESD.
IMB-G41A Micro-ATX Motherboard WARNING: The installation instructions described in this manual should be carefully followed in order to prevent damage to the components and injury to the user. Before and during the installation please DO the following: Read the user manual: o The user manual provides a complete description of the IMB-G41A installation instructions and configuration options. Wear an electrostatic discharge cuff (ESD): o Electronic components are easily damaged by ESD.
IMB-G41A Micro-ATX Motherboard 4.2.1 Socket LGA775 CPU Installation NOTE: To enable Hyper-Threading, the CPU and chipset must both support it. WARNING: CPUs are expensive and sensitive components. When installing the CPU please be careful not to damage it in anyway. Make sure the CPU is installed properly and ensure the correct cooling kit is properly installed. The LGA775 socket is shown in Figure 4-1. Figure 4-1: Intel LGA775 Socket To install the CPU, follow the steps below.
IMB-G41A Micro-ATX Motherboard Step 1: Remove the protective cover. The black protective cover can be removed by pulling up on the tab labeled "Remove". See Figure 4-2. Figure 4-2: Remove Protective Cover Step 2: Open the socket. Disengage the load lever by pressing the lever down and slightly outward to clear the retention tab. Fully open the lever, then open the load plate. See Figure 4-3. Figure 4-3: CPU Socket Load Plate Step 3: Inspect the CPU socket.
IMB-G41A Micro-ATX Motherboard Step 4: Orientate the CPU properly. The contact array should be facing the CPU socket. Step 5: Correctly position the CPU. Match the Pin 1 mark with the cut edge on the CPU socket. Step 6: Align the CPU pins. Locate pin 1 and the two orientation notches on the CPU. Carefully match the two orientation notches on the CPU with the socket alignment keys. Step 7: Insert the CPU. Gently insert the CPU into the socket.
IMB-G41A Micro-ATX Motherboard 4.2.2 Socket LGA775 Cooling Kit Installation WARNING: DO NOT use the original Intel® heat sink and fan. A proprietary one is recommended. Figure 4-5: Cooling Kits (CF-520 and CF-775A) The cooling kit can be bought from IEI. The cooling kit has a heatsink and fan. WARNING: Do not wipe off (accidentally or otherwise) the pre-sprayed layer of thermal paste on the bottom of the heat sink.
IMB-G41A Micro-ATX Motherboard Step 3: Mount the cooling kit. Gently place the cooling kit on top of the CPU. Make sure the four threaded screws on the corners of the cooling kit properly pass through the predrilled holes on the bottom of the PCB. Step 4: Secure the cooling kit. From the solder side of the PCB, align the support bracket to the screw threads on heat sink that were inserted through the PCB holes. (See Figure 4-6) Figure 4-6: Securing the Heat sink to the IMB-G41A Step 5: Tighten the screws.
IMB-G41A Micro-ATX Motherboard 4.2.3 DIMM Installation To install a DIMM, please follow the steps below and refer to Figure 4-7. Figure 4-7: DIMM Installation Step 1: Open the DIMM socket handles. Open the two handles outwards as far as they can. See Figure 4-7. Step 2: Align the DIMM with the socket. Align the DIMM so the notch on the memory lines up with the notch on the memory socket. See Figure 4-7. Step 3: Insert the DIMM. Once aligned, press down until the DIMM is properly seated.
IMB-G41A Micro-ATX Motherboard 4.3 Jumper Settings NOTE: A jumper is a metal bridge used to close an electrical circuit. It consists of two or three metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To CLOSE/SHORT a jumper means connecting the pins of the jumper with the plastic clip and to OPEN a jumper means removing the plastic clip from a jumper. The hardware jumpers must be set before installation. Jumpers are shown in Table 4-1.
IMB-G41A Micro-ATX Motherboard 4.3.1 AT/ATX Power Mode Jumper Label: JAUTO1 Jumper Type: 2-pin header Jumper Settings: See Table 4-2 Jumper Location: See Figure 4-8 The AT Power Select jumper specifies the systems power mode as AT or ATX.
