Installing SIMMs
When installing SIMMs, use 70ns or faster memory chips for
maximum system performance. Faster and slower memory chips
may be intermixed. However, always set the CPU/DRAM Speed
option in SETUP to the slowest chip speed installed.
Remember, larger numbers are slower than smaller numbers
(100ns SIMMs are slower than 70ns SIMMs). For best results,
use memory devices from the same manufacturer.
Caution:
Electrostatic Discharge can result in permanent damage to the equipment.
Always ground yourself by touching the system cabinet before beginning
the following procedure. We strongly recommend using an anti-static wrist
strap attached to cabinet ground.
To Install SIMMs:
1. Remove system cover (see How to Open a Desktop Case,
earlier).
2. Determine memory SIMM configuration (refer to Table 2,
Memory Configuration, on the previous page).
3. 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.
4. Grasping a new SIMM by the edge, remove it from the
antistatic bag.
