Earlier this week, I posted abut ThinkPad W701: Win7 Ultimate x64 suddenly only saw 8GB RAM of 16GB (via: [H]ard|Forum).
One of the search results in my query indicated it would be possible to put 32GB in it.
That’s nice, as the official Lenovo ThinkPad W701 specs and Lenovo ThinkPad W701 2500 Overview & Specs – Laptops – CNET Reviews indicate it should max out with 16GB.
This Google search returns lots of results indicating people actually run it with 32GB RAM using 4x8GB memory modules:
