The service guide shows the location codes of all available resources, including memory card and dimm locations in the system:

lscfg -vp
will show what is installed in your system, from that you should be able to work out what is installed and from that what room you have left.
The system has eight dimm slots per processor card and up to two processor cards per system, page 18 shows the memory slots on the processor cards.
In the service guide check out page 23 onwards for the location codes. They vary slightly between AIX versions.
Page 25 has processor card and dimm location examples so you can determine if you have one or two processor cards.
So if you only see, in the lscfg -vp output, U0.1-P1-C1 and no U0.1-P1-C2 then you only have one processor card and so only eight dimm slots. If you also have a card at U0.1-P1-C1 and another at U0.1-P1-C2 then you have both processor cards installed and so sixteen dimm slots are available.
Then check for U0.1-P1-Cx-My locations in the lscfg -vp output, whare x can be 1 or 2 (processor cards) and y can be 1 to 16 (dimm slots) and you can work out how many dimm slots are in use / available on each processor card.
The lscfg -vp output will also tell you the size of the dimms fitted, you may have no free dimm slots but if the dimms are small you could replace them with bigger ones to increase the memory - and sell the old ones back to the company you buy the new stuff from, or another IBM reseller, or stick them on ebay.
Dimms must be installed in quads (groups of four) with one quad in slots 1, 3, 6 and 8 and the second quad in 2, 4, 5 and 7.
It seems the system supports dimms from 256MB to 2GB giving 1GB to 16GB per processor card - page 18.
There are up to four internal disks, see page 33 for the location codes.
This new forum interface is rubbish, even if you do understand html! Took me ages to make this readable.
