Is your RAM 2x2GB cards?
Your MOBO should have 4 RAM slots.
If this is the case, check your manual, make sure you have the RAM (assuming 2 RAM cards and 4 slots) installed in the correct slots.
If they are in the wrong slots you can get single channel mode, which would explain your scores.
Next option would be to check for updates for the chipset driver and your BIOS.
