Holding the DRAM expansion card by the edges, connect the card to the logic board.

Note: To verify that the upgrade is successful, check the Total Memory message (for systems with virtual memory switched off) or the Built-in Memory message (for systems with virtual memory switched on). The memory size should be 4 MB of DRAM plus the amount of DRAM on the expansion card. If the memory size is incorrect, reseat the DRAM card.
