6. Grasp the card by its outside corners, and ease it out of its connector.
7. If you are removing the card permanently, install a metal filler bracket over the empty card-slot opening.
NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain Federal Communications Commission

Adding Memory

Memory can be increased to a maximum of 768 megabytes (MB) by installing combinations of 32-, 64-, 128-, or 256-MB dual in-line memory
modules (DIMMs) in the three DIMM sockets on the system board.
Your system can support both error checking and correction (ECC) and nonparity synchronous dynamic random-access memory (SDRAM)
DIMMs. However, ECC support is available only if all DIMMs are ECC DIMMs. ECC DIMMs enable your system to correct all single-bit memory
errors and detect multibit memory errors.
When you add system memory, you may install DIMMs in any socket. For optimum operation, Dell recommends that you install a DIMM in socket A
first (closest to the processor) before installing a DIMM in another socket.
