That's really strange that your notebook doesn't recognises it.I know my notebook is different(PA2548) but I now run with an 2gb ddr 800 module + an 1gb ddr 667 module, which works fine, only on 333mhz and Dual Channel is disabled because the're not the same size. the 333mhz is declared bij the memory controller on the cpu which automaticly chooses the slowest speed. Your notebook might not support more then 2gb's, then that's the reason it's not recognised. U can mail Fujitsu Siemens support with that question...
