Installing SIMMs
When installing SIMMs, use 70ns or faster memory chips for maximum
system performance. Different speed SIMMs may be mixed, but only if
you put them different banks. In addition, always set the CPU/DRAM
Speed option in SETUP to match the slowest SIMM. Note that with
SIMMs, larger numbers mean that more time is used to access
information (a 70ns SIMM is slower than a 60ns SIMM). For best results,
use SIMMs from the same manufacturer.
Caution!
Static electric shocks can permanently damage your equipment.
Always ground yourself by touching the metal part of the computer
case before beginning the following procedure. We strongly recom-
mend using an antistatic wrist strap attached to the case ground.
To Install SIMMs:
1. Remove system cover (see How to Open a Desktop Case, earlier).
2. Remove any SIMMs you are replacing with new SIMMs by gently
pulling the metal socket clips away from the SIMM to release the
SIMM from the socket. Hold them out while you are tilting the
SIMM away from the metal clips. Carefully lift the SIMM up and
out.
Caution!
Never use force to remove the module out of the socket. Failure to
properly release the retainer clips may break the socket, causing
expensive damage which is not covered by your warranty.
3. Grasping a new SIMM by the edge, remove it from the antistatic
bag.
4. Insert the bottom edge into the socket slot. Press down firmly on
the SIMM while maintaining the proper angle of insertion.
