7 Chapter 2 Installing the Motherboard Safety Precautions • • • • • Follow these safety precautions when installing the motherboard Wear a grounding strap attached to a grounded device to avoid damage from static electricity Discharge static electricity by touching the metal case of a safely grounded object before working on the motherboard Leave components in the static-proof bags they came in Hold all circuit boards by the edges.
8 Do not over-tighten the screws as this can stress the motherboard. Checking Jumper Settings This section explains how to set jumpers for correct configuration of the motherboard. Setting Jumpers Use the motherboard jumpers to set system configuration options. Jumpers with more than one pin are numbered. When setting the jumpers, ensure that the jumper caps are placed on the correct pins. The illustrations show a 2-pin jumper. When the jumper cap is placed on both pins, the jumper is SHORT.
9 Checking Jumper Settings The following illustration shows the location of the motherboard jumpers. Pin 1 is labeled. Jumper Settings Jumper Type Description CLR_CMOS 3-pin CLEAR CMOS Setting (default) 1-2: NORMAL 2-3: CLEAR 1 Before clearing the CMOS, make sure to CLR_CMOS turn the system off. To avoid the system instability after clearing CMOS, we recommend users to enter the main BIOS setting page to “Load Default Settings” and then “Save & Exit Setup”.
10 Installing Hardware Installing the Processor Caution: When installing a CPU heatsink and cooling fan make sure that you DO NOT scratch the motherboard or any of the surfacemount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes across the motherboard, you may cause serious damage to the motherboard or its components. On most motherboards, there are small surface-mount resistors near the processor socket, which may be damaged if the cooling fan is carelessly installed.
11 CPU Installation Procedure The following illustration shows CPU installation components. 1 2 3 4 5 6 Unhook the locking lever of the CPU socket. Pull the locking lever away from the socket and raising it to the upright position. Match the pin1 corner marked as the beveled edge on the CPU with the pin1 corner on the socket. Insert the CPU into the socket. Do not use force. Push the locking lever down and hook it under the latch on the edge of socket. Apply thermal grease to the top of the CPU.
12 Installing Memory Modules This motherboard accommodates two memory modules. It can support two 240-pin DDR3 1333/1066. The total memory capacity is 16 GB. DDR3 SDRAM memory module table Memory module DDR3 1066 DDR3 1333 Memory Bus 533 MHz 667 MHz You must install at least one module in any of the two slots. Total memory capacity is 16 GB. Do not remove any memory module from its antistatic packaging until you are ready to install it on the motherboard. Handle the modules only by their edges.
13 Table: DDR3 (memory module) QVL (Qualified Vendor List) The following DDR3 1333/1066 memory modules have been tested and qualified for use with this motherboard.
14 Due to the Phenom CPU and memory module limitation, the DRAM may need to adjust the voltage for supporting DDR3 1066. The memory modules which can be used stably are listed in the above QVL table for reference. Expansion Slots Installing Add-on Cards The slots on this motherboard are designed to hold expansion cards and connect them to the system bus. Expansion slots are a means of adding or enhancing the motherboard’s features and capabilities.
15 Follow these instructions to install an add-on card: 1 2 3 Remove a blanking plate from the system case corresponding to the slot you are going to use. Install the edge connector of the add-on card into the expansion slot. Ensure that the edge connector is correctly seated in the slot. Secure the metal bracket of the card to the system case with a screw.
