Installing Memory Modules - Abit PR5 User Manual

Installing Memory Modules

Installing memory modules is easy, but there are a few
important precautions you should take whether you are
installing SIMM or DIMM modules.
The most important is to guard against damage to the
modules from static discharge. A strong enough discharge
can make a module unusable and ruin your investment.
If you' re not familiar with static precautions, you may
want to review the information on this in Section 1.
In addition to taking precautions against damage from
static discharge, you should avoid touching a module' s
edge connector when you are handling it. The edge con-
nector is the part of the module that inserts in the socket
on the mainboard. Oil from your fingers can cause corro-
sion on the connector contacts as well as in the sockets,
possibly resulting in an eventual malfunction.
Module Orientation
All memory modules must be oriented correctly before
you can insert them in the socket. SIMM and DIMM
modules have different designs for ensuring correct mod-
ule orientation.
SIMM modules have one lower corner cut away to en-
sure they will only insert in a socket in the correct orien-
tation. The SIMM sockets have an extension from one of
the socket guide posts that prevents the module from in-
serting in the socket if it isn' t oriented correctly.
DIMM modules have a long edge connector divided into
sections, two longer and one shorter. The DIMM sockets
are divided accordingly, so the orientation is obvious.
Installing SIMMs
To install any kind of SIMM module do as follows:
1. Orient the cut-away corner so that it is at the lower
end of the socket.
2. Insert the module edge into the socket at about a
45° angle so that the contacts are as far in as they
will go.
3. Push the module up into the retaining clips so that
the clips clamp over the edge of the module. The
holes at each end of the module should fit over the
protrusion on the guide post.
It is a good idea to use the sockets from left to right to
make installation easier.
