That motherboard accepts either SD-RAM or DDR RAM, but you cannot use both together. If you wish to add extra RAM to upgrade, you will need to get more of the type you currently have installed.

It will accept SD-RAM of up to PC133 speed, or DDR-RAM of up to PC2700 rating.

Download and install CPU-Z http://www.cpuid.org/cpuz.php Run it and check the memory tab to verify what type of RAM you currently have installed.
