The max ram on the new T400 's and T500 's is 8GB of DDR3 RAM (i.e. two 4GB-DIMMS). Of course, in order to take advantage of 4GB or more RAM, you need to have a 64-bit OS.
For full system specs, you can check out the Personal System Reference Sheets by downloading the file called "tabook.pdf" on the ThinkPad Literature page.
