Memory Expansion - Fujitsu LIFEBOOK S Series Easy Manual

Memory expansion

Your notebook has 256 Mbyte - 2 Gbyte of main memory installed, depending on the upgrade level.
The notebook will not start without memory modules, as no fixed main memory is installed.
Your notebook supports the Dual-Channel DDR2 technology, which increases the processor and
main memory performance.
The Dual-Channel DDR2 technology can only be used with two identical memory modules.
i
When two different memory modules are installed, only the "single-channel" performance
is supported.
