The Intel LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
When you buy a boxed Intel processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intelcertified multidirectional heatsink and fan. Your Intel LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install. If you purchased a separate CPU heatsink and fan assembly, ensure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly. Ensure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.
Installing the CPU heatsink and fan
To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, ensuring that the four fasteners match the holes on the motherboard.
Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan connector. B
Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place.
The type of CPU heatsink and fan assembly may differ, but the installation steps and functions should remain the same. The illustration above is for reference only.
Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.
Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.

1. 2. 3.

To uninstall the CPU heatsink and fan:
Uninstalling the CPU heatsink and fan
Disconnect the CPU fan cable from the connector on the motherboard. Rotate each fastener counterclockwise. Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the motherboard.
Carefully remove the heatsink and fan assembly from the motherboard. Rotate each fastener clockwise to ensure correct orientation when reinstalling.

After installing the expansion card, configure it by adjusting the software settings. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for information on BIOS setup. Assign an IRQ to the card. Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support Share IRQ or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.

Jumpers
Clear RTC RAM (3-pin CLRTC) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.
To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. 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. 3. Plug the power cord and turn ON the computer. 4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure!
If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery. You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut down and reboot the system, then the BIOS automatically resets parameter settings to default values. Due to the chipset limitation, AC power off is required before you use the C.P.R. function. You must turn off and on the power supply or unplug and plug the power cord before rebooting the system.

USB device wake-up (3-pin USBPW1-4, USBPW5-8) Set the jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).
Keyboard power (3-pin KBPWR) This jumper allows you to enable or disable the keyboard wake-up feature. When you set this jumper to pins 23 (+5VSB), you can wake up the computer by pressing a key on the keyboard (the default is the Space Bar)s. This feature requires an ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS.
