Installing System Memory

!Before opening the system unit, save and close all open files, exit all open applications, turn off the power to all attached peripheral devices, shut down the computer, and unplug the power cord.

1Choose the size of the memory module and configuration as shown in the following table. Memory modules can vary in size and speed between sockets. The minimum memory size is 8 MB. The maximum memory size is 512 MB. The BIOS automatically detects the type, size and speed of the memory modules.

*All models ship with at least 128 MB of RIMM™ memory. RIMM memory is expandable to 512 MB. Your model may ship with more than 128 MB of RIMM™ memory if you purchased it through the VAIO Direct Web site.

✍Use only PC-800 Rambus RIMM memory modules. Direct Rambus RIMMS must be upgraded in pairs. Do not leave the second slot of either bank empty. The second slot must be filled with either RIMM or CRIMM modules.
