Chapter 2 Hardware Setup This chapter provides you with the information about hardware setup procedures. While performing the installation, be careful in holding the components and following the installation procedures. For some components, if you install in the wrong orientation, the components will not work properly. Use a grounded wrist strap before handling computer components. Static electricity may damage the components.

MS-7681 Screw Holes When you install the mainboard, you have to place the mainboard into the chassis in the correct direction. The locations of screws holes on the mainboard are shown as below. Chapter 2 BATT + The side has to toward the rear, the position for the I/O shield of the chassis. Screw holes Refer above picture to install standoffs in the appropriate locations on chassis and then screw through the mainboard screw holes into the standoffs.
Hardware Setup CPU (Central Processing Unit) When you are installing the CPU, make sure to install the cooler to prevent overheating. If you do not have the CPU cooler, consult your dealer before turning on the computer. For the latest information about CPU, please visit http://www.msi.com/index. php?func=cpuform2 Important Overheating Overheating will seriously damage the CPU and system. Always make sure the cooling fan can work properly to protect the CPU from overheating.
MS-7681 CPU & Cooler Installation When you are installing the CPU, make sure the CPU has a cooler attached on the top to prevent overheating. Meanwhile, do not forget to apply some thermal paste on CPU before installing the heat sink/cooler fan for better heat dispersion. Follow the steps below to install the CPU & cooler correctly. Wrong installation will cause the damage of your CPU & mainboard. 2. Open the load level. 3. Lift the load lever up to fully open position. 4.
Hardware Setup 6. Engage the load lever while pressing down lightly onto the load plate. 8. Make sure the four hooks are in porper position before you install the cooler. 7. Secure the lever near the hook end under the retention tab. 9. Align the holes on the mainboard with the heatsink. Push down the cooler until its four clips get wedged into the holes of the mainboard. Important • Confirm if your CPU cooler is firmly installed before turning on your system.
MS-7681 10. Press the four hooks down to fasten the cooler. 11. Turn over the mainboard to confirm that the clip-ends are correctly inserted. Chapter 2 Mainboard Hook 12. Finally, attach the CPU Fan cable to the CPU fan connector on the mainboard. Important • Read the CPU status in BIOS. • Whenever CPU is not installed, always protect your CPU socket pin with the plastic cap covered to avoid damaging. • Mainboard photos shown in this section are for demonstration of the CPU/ cooler installation only.
Hardware Setup Memory These DIMM slots are used for installing memory modules. For more information on compatible components, please visit http://www.msi.com/index.php?func=testreport DDR3 240-pin, 1.5V 48x2=96 pin 72x2=144 pin Memory Population Rule Please refer to the following illustrations for memory population rules. Dual-Channel mode Population Rule In Dual-Channel mode, the memory modules can transmit and receive data with two data bus lines simultaneously.
MS-7681 Installing Memory Modules 1. The memory module has only one notch on the center and will only fit in the right orientation. 3. Manually check if the memory module has been locked in place by the DIMM slot clips at the sides. Notch Volt Important You can barely see the golden finger if the memory module is properly inserted in the DIMM slot. 2-9 Chapter 2 2. Insert the memory module vertically into the DIMM slot.
Hardware Setup Power Supply ATX 24-pin Power Connector: JPWR1 This connector allows you to connect an ATX 24-pin power supply. To connect the ATX 24-pin power supply, make sure the plug of the power supply is inserted in the proper orientation and the pins are aligned.
