I have a Panasonic Toughbook CF-27, specifically a Mk2 model with the 300 MHz Pentium II PE. It has 128 MB of RAM soldered on the board and has an empty SDRAM slot: does anybody know what is the maximum amount of RAM this machine can handle? (OS is Windows 2000). Also, CPU-Z states that the pre-installed RAM is running at 66 Mhz: do I have to buy a stick with matching frequency or is it okay to mismatch?
