Installation Instructions


30-pin, 72-pin SIMMs

1) PREPARATION
Unplug all cables, turn off all power and discharge yourself of static electricity by touching any metal object.

IMPORTANT
All systems have unique memory upgrade specifications. Some may specify that more than one SIMM/DIMM be installed at the same time, usually in pairs or in sets of 4. Some systems have memory soldered onto the mother board which will leave all memory sockets available for expansion.

Refer to your owner's manual and be sure to follow all of the instructions. A "bank" is one or more SIMM/DIMM sockets. Supplementary memory should almost always be installed in the lowest numbered open bank and each bank should be completely filled unless your owner's manual states differently. Banks are indicated by a silk screen on the system board, usually numbered 0, 1, 2, etc., or lettered A, B, C, etc., Refer to your owner's manual for instructions. Do not touch the bottom edge connector or any of the components on the SIMM/DIMM. Do not use excessive force when installing. Install one SIMM/DIMM at a time.

2) DISASSEMBLE COMPUTER
Refer to your owner's manual for the proper instructions. Once you have located the SIMM/DIMM sockets, you may need to remove or move previously installed SIMM(s)/DIMM(s). Refer to your owner's manual for proper configuration.

3) REMOVING MEMORY
ANGLED SIMMs (See Figure A)


With the use of both of your hands, carefully spread apart the clips while pushing forward on the back side of the SIMM.
After the SIMM clears the retaining clips, it can be easily removed by pulling the SIMM up and out of the socket.

VERTICAL SIMMs (See Figure B)


With the use of both of your hands, carefully spread apart the clips while pushing back on the front side of the SIMM.
After the SIMM reaches a 60 degree angle, it can be easily removed by pulling it out at that angle.

4) INSTALLING MEMORY
ANGLED SIMMs (See Figure D)


Align the SIMM over the SIMM socket. For a 72-pin SIMM, match the notch in the middle of the pins with the raised notch in the socket. Push the SIMM directly down into the socket making sure that the receptacle pins align with the contacts.
After the SIMM is pushed directly down as far as it can go, carefully hinge the SIMM back. Resistance may occur as you push the SIMM back and it hits the retaining clips. Continue to push the SIMM back until both sides of the SIMM are locked down by the clips.

VERTICAL SIMMs (See Figure E)


Align the SIMM at a 60 degree angle towards the SIMM socket. For a 72-pin SIMM, match the notch in the middle of the pins with the raised notch in the socket. Keeping the SIMM at the same angle, push it into the receptacle making sure that the pins are lined up with the contacts on the SIMM.
After you have pushed the SIMM in as far as it will go, carefully hinge the SIMM up. There may be some resistance, but continue to push the SIMM until both sides are locked in place by the clips.

5) REASSEMBLE COMPUTER
Refer to your owner's manual for proper instructions.

6) SYSTEM SET-UP AND VERIFICATION
Systems will automatically recognize the additional memory.
