The following RAM configurations are supported:

NOTE: These computers have a total of two memory slots and ship with one 512MB Dual In-line Memory Module (DIMM) in one slot. Memory modules can be added and used in any size combination, to a maximum memory amount of 1024MB.

1024MB 512MB 512MB

When purchasing memory to install into the computer, select D ual I n-line M emory M odules (DIMMs) meeting the following specifications and guidelines:

  • Double Data Rate-Synchronous Dynamic Random Access Memory (DDR-SDRAM)
  • PC2100
  • 184 gold pin
  • 2.5 Volts
  • Single or double-sided

Follow this procedure to add memory to the desktop computer.

WARNING: There is a risk of hardware damage. Ensure the computer is shut down and disconnected from power before following this procedure. It is also recommended to use a grounding strap to discharge static electricity during this procedure. If one is not available, touch an exposed metal part of the chassis before handling the memory module.


  • Properly installing non-Sony memory does not void the limited warranty.
  • Handle memory modules only by the edges. Do not touch the connectors or circuits.

NOTE: Place the computer on a hard, flat surface when performing this procedure.

  1. Disconnect all peripheral devices such as printers, displays, and speakers.
  2. Unplug the power cable from the computer.
  3. Facing the back of the computer, remove the two rear panel access screws [FIG. 1] .
  4. Remove the top access panel [FIG. 1] by gently pulling the top away from the computer.
  5. Lift up and fold down the bottom access panel [FIG. 1] to expose the internal memory slot cover [FIG. 2] .
  6. Pull down on the internal memory slot cover [FIG. 2] to expose the memory slots [FIG. 3] on the motherboard.
  7. Holding the Dual In-line Memory Modual (DIMM) [FIG. 4] only by the edges, remove it from the anti-static package.
  8. Align the DIMM over the available memory slot [FIG. 3] , ensuring that the bridges in the memory slot are align with the notches in the memory module.
  9. NOTE: Because the memory module and memory slot are keyed, the memory module can only be inserted into the slot one way.

  10. Insert the bottom edge of the DIMM into the slot [FIG. 5] and press gently and evenly against the upper corners until the DIMM is seated into the slot.
  11. NOTES:

    • To avoid damaging the DIMM socket, move the memory slot tabs slightly outward [FIG. 6] to relieve pressure. The DIMM should then click easily into place.
    • The latches on both sides of the memory slot will snap into position automatically once the DIMM is fully inserted.
  12. Close the internal memory slot cover.
  13. Fold up the bottom access panel.
  14. Attach the top access panel.
  15. Replace the rear panel access panel screws.
  16. Reconnect all peripheral devices and plug in the computer.

Follow this procedure to upgrade the Random Access Memory (RAM).
