Memory Slot detection

Are there any programs that will recognize memory slots available and slots used? Example: If I have a machine with 2 32mb dimms in a compaq deskpro mmx, and 1 slot is not being used. is there a utility I can run that will get the information? (total slots, total chips, size of each chip). I tried Track-It and Blue Ocean, neither of these programs worked, they only show how much total memory is installed.
