To replace system memory:
1. Ensure the pins on the DIMMs or SIMMs match the socket keying.
2. Align pin 1 on the memory module with pin 1 of the socket.
3. If adding a SIMM, insert the memory module into the socket at a 45 degree angle. If
adding a DIMM, insert the memory module into the socket at a 90 degree angle. Use
even pressure across the top of the module; then push the module upright until it locks
in place. See the following figure.
CAUTION Do not use a rocking motion as you install the memory module. Doing so might damage the
module, the socket, or both.
