■ If you are installing a new DIMM, see “Installing DIMMs” on page 61 of the Service Manual.
■ If you are finished, replace the left side access panel.

Installing DIMMs

When you install a DIMM in the workstation, keep the following guidelines in mind:
   * DIMM slots are numbered 0 to 3. Slot 0 is closest to the CPU
   * DIMMs must be installed and removed in pairs
   * Populate DIMM slot 1 and DIMM slot 3, then DIMM slot 0 and DIMM slot 2
   * For a single DIMM configuration use DIMM slot 1
2. Gently lay the system on its right side on a stable, nonslip surface.
3. Identify the location into which you will install a DIMM.
4. Align the DIMM with the proper slot.
Note - Be sure to align the notch in the DIMM with the notch in the connector.
5. Place the DIMM in the slot.
6. Evenly press the DIMM straight down into the DIMM slot until both ejector levers lift and click, locking the DIMM in the DIMM slot.
Note - The DIMM is seated when you hear a click and the DIMM ejector levers are in the vertical position.
7. Repeat Step 3 through Step 6 for each DIMM that you want to replace.

The system automatically detects the amount of memory installed. Run the BIOS setup to view the new value for total system memory and make a note of it.
