Locate the CPU socket on the motherboard.182. Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab.183. Lift the load lever in the direction of the arrow to a 135º angle.184. Lift the load plate with your thumb and forefinger to a 100º angle (A), then push the PnP cap from the load plate window to remove (B).195. Position the CPU over the socket, making sure that the gold triangle is on the bottom-left corner of the socket then fit the socket alignment key into the CPU notch.196. Close the load plate (A), then push the load lever (B) until it snaps into the retention tab.197. If installing a dual-core CPU, connect the chassis fan cable to the CHA_FAN1 connector to ensure system stability.191.4.2 Installing the CPU Heatsink and Fan201. Place the heatsink on top of the installed CPU, making sure that the four fasteners match the holes on the motherboard.202. Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place.213. Connect the CPU fan cable to the connector on the motherboard labelled211.4.3 Uninstalling the CPU Heatsink and Fan221. Disconnect the CPU fan cable from the connector on the motherboard.222. Rotate each fastener counterclockwise.223. Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the motherboard224. Carefully remove the heatsink and fan assembly from the motherboard.225. Rotate each fastener clockwise to ensure correct orientation when reinstalling.231.5 System Memory241.5.1 DIMM Sockets Location241.5.2 Memory Configurations251.5.2.1 Qualified Vendors Lists (QVL) - DDR2-800MHz Capability261.5.2.2 Qualified Vendors Lists (QVL) - DDR2-667MHz Capability271.5.2.3 Qualified Vendors Lists (QVL) - DDR2-553MHz Capability291.5.3 Installing a DIMM301. Unlock a DIMM socket by pressing the retaining clips outward302. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket.303. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.301.5.4 Removing a DIMM311. Simultaneously press the retaining clips outward to unlock the DIMM.312. Remove the DIMM from the socket.311.6 Expansion Slots321.6.1 Installing an Expansion Card321. Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card.322. Remove the system unit cover (if your motherboard is already installed in a chassis).323. Remove the bracket opposite the slot that you intend to use. Keep the screw for later use.321.6.2 Configuring an Expansion Card321.6.3 Standard Interrupt Assignments331.6.4 PCI Slots34i945G-IGA has two PCI slots (i945G-IGA-IM has four slots). The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications. The figure shows a LAN card installed on a PCI slot.341.6.5 PCI Express X16 Slot34This motherboard supports one PCI Express x16 graphic cards that comply with the PCI Express specifications. The following figure shows a graphics card installed on the PCI Express x16 slot.341.6.6 PCI Express X4 Slot34The figure shows a network card install on the PCI Express X4 slot.341.7 Jumpers351.7.1 Clear RTC RAM (CLRTC)351. Turn OFF the computer and unplug the power cord.352. Remove the onboard battery.353. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.354. Re-install the battery.355. Plug the power cord and turn ON the computer.356. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.351.7.2 Keyboard Power (KBPWR)361.8 Connectors371.8.1 Rear Panel Connectors37Parallel port connector37IEEE 1394a connector37LAN (RJ-45) connector37This port connects a tape, CD, DVD player, or other audio sources.38This port connects a headphone or a speaker.
