Connectors, Headers And Switches - Abit AB-AT7-MAX2 Manual

Installing the Motherboard
When you install a DDR DIMM module fully into the DDR DIMM socket, the eject tab should be
locked into the DDR DIMM module very firmly and fit into its indention on the both sides.
It is difficult to differentiate between the PC 1600, PC 2100, PC 2700 and PC 3200 DDR SDRAM
modules from the exterior. The only way you can identify them is to look at the sticker on the DDR
SDRAM module. The sticker will tell you which kind of structure module the DDR SDRAM is.

3-4. Connectors, Headers and Switches

Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are
usually connected one-by-one to connectors located on the motherboard. You need to carefully pay
attention to any connection orientation the cables may have and, if any, notice the position of the first pin
of the connector. In the explanations that follow, we will describe the significance of the first pin.
We will show you all of the connectors, headers and switches here, and tell you how to connect them.
Please pay attention and read the entire section for necessary information before attempting to finish all of
the hardware installation inside the computer chassis.
Figure 3-7 shows you all of the connectors and headers that we'll discuss in the next section, you can use
this diagram to visually locate each connector and header we describe.
All connectors, headers and switches mentioned here, will depend on your system configuration. Some
features you may (or may not) have and need to connect or configure depending on the peripheral. If your
system doesn't have such add-on cards or switches you can ignore some special feature connectors.
Step 5. Insert the DDR DIMM module into the
expansion socket as shown in the illustration.
Note how the module is keyed to the socket.
You can refer to Figure 3-6 for the details. This
insures the DDR DIMM module will be
plugged into the socket in one way only. Firmly
press the DDR DIMM module into DDR DIMM
socket, making certain the module is completely
seated in the DDR DIMM socket.
Step 6. Once the DDR DIMM module has been installed,
the installation is complete and the computer's
cover can be replaced. Or you can continue to
install other devices and add-on cards that are
mentioned in the following section.
