the following list details some of the items that are available from your
reseller or TOSHIBA dealer:
Memory Kit A 1 GB or 2 GB memory module
(DDR3-1066/1333) can easily be installed in the
computer.
Some models could install a 1 GB or 2 GB
memory module (DDR2-800/DDR3-1066/
DDR3-1333). For detailed information on
memory module type, please contact your
service provider.
2GB module is supported by validated optional
memory only.
