and, to cut the clutter, try...

    # dmidecode -t memory

on most servers, the first entry will be the mainboard memory array, 
which should show how many slots and max capacity, while the rest of the 
entries will show the installed modules.  This data is read from the i2c 
bus, and is stored in the serial eprom on the memory modules, so if you 
have a sketchy system, it may not be 100% accurate.
