to the information your chip manufacturer has given you. If you are
inexperienced in installing chips, you may want to read a good
hardware reference book before you begin. One recommendation is
by Winn L. Rosch, The Winn Rosch Hardware Bible (New York;
Brady), 1989.
Warning! Ground yourself when handling memory devices
and insert them with as little force as possible!
Make sure that you are properly grounded before handling memory
devices or the board. You can discharge any static electricity you may
have built up by touching the case (metal) of your computer before
you begin installation. You should also avoid contact with materials
that hold a static charge such as plastic, vinyl, and styrofoam. Avoid
touching the exposed circuit connectors.
• Treat connectors gently
The legs of integrated circuits are delicate, and may bend before
reaching the bases of sockets. Inspect each leg before you begin, test-
fit it gently into the socket, and straighten any bent legs before you
insert.
• Install memory chips with the correct orientation
Memory chips must be installed the correct way around. If this is not
done the chip will be damaged. Each chip and it's corresponding
socket will have a small ident (or spot) at it's top end. These must be
aligned when the chip is inserted into the socket.
