The cap plays an important role in protecting contact pins. In order to prevent bent pin, PUT ON the cap after operation or testing.

For detailed information on how to install your heatsink and fan assembly, please refer to the instruction manual came packed with the heatsink and fan assembly you bought.

7. Lower the plate onto the CPU package. Engage the load lever while gently pressing down the load plate.

8. Secure the lever with the hook under retention tab.

9. Place the heatsink and fan assembly onto the socket. Align the four fasteners toward the four mounting holes on the motherboard.

10. Press each of the four fasteners down into the mounting holes.

11. Rotate the fastenerclock-wiseto lock the heatsink and fan assembly into position.

12. Attach thefour-pinpower plug from the heatsink and fan assembly to the CPU FAN connector.

2-3.Install System Memory

This motherboard provides four 240-pinDIMM slots for Dual Channel DDR2 533/400 memory modules with memory expansion size up to 4GB.

To reach the optimum performance in dual-channelconfigurations, install identical DDR2 DIMM pairs for each channel.

Install DIMMs with the same CAS latency. To reach the optimum compatibility, obtain memory modules from the same vendor.

Due to chipset resource allocation, the system may detect less than 4GB of system memory in the installation of four 1GB DDR2 memory modules.

Due to chipset limitation, 128MB DIMM modules or double-sidedx16 memory chips are not supported.

There are several methods of different DDR2 configurations depending on how the DIMMs are populated on each system memory channel:

[Single Channel]: only one channel is populated.

Power off the computer and unplug the AC power cord before installing or removing memory modules.

1.Locate the DIMM slot on the board.

2.Hold two edges of the DIMM module carefully, keep away of touching its connectors.

3.Align the notch key on the module with the rib on the slot.

4.Firmly press the module into the slots until the ejector tabs at both sides of the slot

automatically snaps into the mounting notch. Do not force the DIMM module in with extra force as the DIMM module only fit in one direction.

5.To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and then pull out the DIMM module.

ATTENTION: Static electricity can damage the electronic components of the computer or optional boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a grounded metal object briefly.

2-4.Connectors, Headers and Switches

Here we will show you all of the connectors, headers and switches, and how to connect them. Please read the entire section for necessary information before attempting to finish all the hardware installation inside the computer chassis. A complete enlarged layout diagram is shown in Chapter 1 for all the position of connectors and headers on the board that you may refer to.

WARNING: Always power off the computer and unplug the AC power cord before adding or removing any peripheral or component. Failing to so may cause severe damage to your motherboard and/or peripherals. Plug in the AC power cord only after you have carefully checked everything.

(1). ATX Power Input Connectors

This motherboard provides two power connectors to connect power supplier.

NOTE: This24-pinpower connector “ATXPWR1” is compliant to the former20-pintype. Pay attention to the orientation when doing so(Pin-11,12, 23, and 24 should be leftun-connected).

(6). Front Panel Switches & Indicators Headers

This header is used for connecting switches and LED indicators on the chassis front panel.

Watch the power LED pin position and orientation. The mark “+” align to the pin in the figure below stands for positive polarity for the LED connection. Please pay attention to connect these headers. A wrong orientation will only cause the LED not lighting, but a wrong connection of the switches could cause system malfunction.

HLED (Pin 1, 3):

Connects to the HDD LED cable of chassis front panel.

RST (Pin 5, 7):

Connects to the Reset Switch cable of chassis front panel.

SPKR (Pin 13, 15, 17, 19):

Connects to the System Speaker cable of chassis.

SLED (Pin 2, 4):

Connects to the Suspend LED cable (if there is one) of chassis front panel.

PWR (Pin 6, 8):

Connects to the Power Switch cable of chassis front panel.
