KR7A-133/KR7A-133R
2-8
Most of the DDR memory 1GB modules available
now consist of 64 M x 4 chip, which can't be used on
KR7A-133/KR7A-133R motherboard. Before
purchasing the memory module, we suggest users
carefully check out the memory specification, which
should be provided by memory module vendor. The
left picture illustrates a DDR 1 GB module made by
64 M x 4 chip and special technology- stacking two
memory chips together. This kind of memory can't be
supported by VIA KT266A chipset.
2-4. 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 2-7 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.
Note
This components diagram will be slightly different because there are a number of models. We’ll use
the KR7A-133R motherboard as standard; all descriptions of connector and header will be based on
the KR7A-133R motherboard.
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.
