You can increase your computer memory by installing memory modules on the system board. For information on the type of memory supported by your computer, see "Specifications." 1. 2.
At start-up the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required. It then subtracts the reserved address space from 4 GB to determine the amount of usable space. l If the total installed computer memory is less than the usable space, all installed computer memory is available for use only by the operating system.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module. When the memory module is properly seated in the socket, the securing clips on the memory module socket should align with the securing clips on the other sockets with memory modules installed. 5.
