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