max RAM on T400 series

[dwsteele]

I am considering purchase of a new Thinkpad T400, but would like to run a 64-bit operating system (Linux) and was surprised to see a max of 3GB RAM available.  Is this a fixed limit, or will there be an option to add more RAM ? Thanks.

i thought the max ram for it was 8 gig of DDR 3 so dimm ram.

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.
