Adding Memory
In the future you may want to install memory modules to expand the 
functionality of your computer. You can increase memory up to 256 MB 
(128 MB x 2), by installing optional memory modules. For PCG-F490, 128 
MB of memory are already installed (128 MB x 1). For PCG-F480 and 
PCG-F420, 64 MB of memory are already installed (64 MB x 1). You can 
add an expansion memory module in a slot. 64 MB and 128 MB 
expansion memory modules are available as optional memory modules. 
For memory upgrades, use only PC-100 SDRAM SO-DIMM (gold lead 
contacts). Sony computer supplies, accessories, and peripherals can be 
purchased from your Sony-authorized dealer or by contacting Sony at
