Hardware Installation - 13 - 1-3 Installing the CPU and CPU Cooler Read the following guidelines before you begin to install the CPU: •Make sure that the motherboard supports the CPU. (Go to GIGABYTEs website for the latest CPU support list.) •Always turn off the computer and unplug the power cord from the power outlet before installing the CPU to prevent hardware damage. •Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may locate the notches on both sides of the CPU and alignment keys on the CPU socket.) •Apply an even and thin layer of thermal grease on the surface of the CPU. •Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage of the CPU may occur. •Set the CPU host frequency in accordance with the CPU specifications. It is not recom- mended that the system bus frequency be set beyond hardware specifications since it does not meet the standard requirements for the peripherals. If you wish to set the fre- quency beyond the standard specifications, please do so according to your hardware specifications including the CPU, graphics card, memory, hard drive, etc. Hyper-Threading Technology System Requirements: (Go to Intels website for more information about the Hyper-Threading Technology) •An Intel ® CPU that supports HT Technology •A chipset that supports HT Technology •An operating system that is optimized for HT Technology •A BIOS that supports HT Technology and has it enabled (Refer to Chapter 2, BIOS Setup, Advanced BIOS Features, for instructions on enabling the HT Technology.) 1-3-1 Installing the CPU A. Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.

GA-945GCM-S2L/S2C Motherboard - 14 - B. Follow the steps below to correctly install the CPU into the motherboard CPU socket. Step 2: Lift the metal load plate from the CPU socket. (DO NOT touch socket contacts.) Step 4: Hold the CPU with your thumb and index fingers. Align the CPU pin one marking (triangle) with the pin one corner of the CPU socket (or you may align the CPU notches with the socket alignment keys) and gently insert the CPU into position. Step 3: Remove the protective socket cover from the load plate. (To protect the CPU socket, always replace the protective socket cover when the CPU is not installed.) Step 5: Once the CPU is properly inserted, replace the load plate and push the CPU socket lever back into its locked position. Before installing the CPU, make sure to turn off the computer and unplug the power cord from the power outlet to prevent damage to the CPU. Step 1: Completely raise the CPU socket lever.

Hardware Installation - 15 - 1-3-2 Installing the CPU Cooler Follow the steps below to correctly install the CPU cooler on the motherboard. (The following procedure uses Intel® boxed cooler as the example cooler.) Step 1: Apply an even and thin layer of thermal grease on the surface of the installed CPU. Step 3: Place the cooler atop the CPU, aligning the four push pins through the pin holes on the motherboard. Push down on the push pins diagonally.Step 4: You should hear a click when pushing down each push pin. Check that the Male and Female push pins are joined closely. (Refer to your CPU cooler instal- lation manual for instructions on installing the cooler.) Use extreme care when removing the CPU cooler because the thermal grease/tape between the CPU cooler and CPU may adhere to the CPU. Inadequately removing the CPU cooler may damage the CPU. Step 5: After the installation, check the back of the motherboard. If the push pin is inserted as the picture above, the installation is complete.Step 6: Finally, attach the power connector of the CPU cooler to the CPU fan header (CPU_FAN) on the motherboard. Step 2: Before installing the cooler, note the direction of the arrow sign on the male push pin. (Turning the push pin along the direction of arrow is to remove the cooler, on the contrary, is to install.) Male Push Pin Female Push Pin The Top of Female Push Pin Direction of the Arrow Sign on the Male Push Pin
GA-945GCM-S2L/S2C Motherboard - 16 - 1-4 Installing the Memory Read the following guidelines before you begin to install the memory: •Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used. (Go to GIGABYTEs website for the latest memory support list.) •Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage. •Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction. DDRII1 DDRII2 1-4-1 Dual Channel Memory Configuration This motherboard provides two DDR2 memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth. The two DDR2 memory sockets are divided into two channels and each channel has one memory socket as following: Channel 0: DDRII1 Channel 1: DDRII2 Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode. 1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed. 2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used.
Hardware Installation - 17 - 1-4-2 Installing a Memory Notch DDR2 DIMM Before installing a memory module , make sure to turn off the computer and unplug the power cord from the power outlet to prevent damage to the memory module. DDR2 DIMMs are not compatible to DDR DIMMs. Be sure to install DDR2 DIMMs on this motherboard. A DDR2 memory module has a notch, so it can only fit in one direction. Follow the steps below to correctly install your memory modules in the memory sockets. Step 1: Note the orientation of the memory module. Spread the retaining clips at both ends of the memory socket. Place the memory module on the socket. As indicated in the picture on the left, place your fingers on the top edge of the memory, push down on the memory and insert it vertically into the memory socket. Step 2: The clips at both ends of the socket will snap into place when the memory module is securely inserted.
GA-945GCM-S2L/S2C Motherboard - 18 - 1-5 Installing an Expansion Card Read the following guidelines before you begin to install an expansion card: •Make sure the motherboard supports the expansion card. Carefully read the manual that came with your expansion card. •Always turn off the computer and unplug the power cord from the power outlet before installing an expansion card to prevent hardware damage. Follow the steps below to correctly install your expansion card in the expansion slot. 1 . Locate an expansion slot that supports your card. Remove the metal slot cover from the chassis back panel. 2. Align the card with the slot, and press down on the card until it is fully seated in the slot. 3. Make sure the metal contacts on the card are completely inserted into the slot. 4. Secure the cards metal bracket to the chassis back panel with a screw. 5. After installing all expansion cards, replace the chassis cover(s). 6. Turn on your computer. If necessary, go to BIOS Setup to make any required BIOS changes for your expansion card(s). 7. Install the driver provided with the expansion card in your operating system. PCI Slot PCI Express x1 Slot PCI Express x16 Slot Example: Installing and Removing a PCI Express x16 Graphics Card: •Installing a Graphics Card: Gently push down on the top edge of the card until it is fully inserted into the PCI Express x16 slot. Make sure the card is securely seated in the slot and does not rock. •Removing the Card: Gently push back on the lever on the slot and then lift the card straight out from the slot.
