Correction note: this page previously described the Portégé X30-G as having soldered, non-upgradeable memory capped at 16GB. It actually has two SO-DIMM sockets and supports up to 32GB — 16GB is simply the common factory configuration. This is one to check on your own machine before assuming it cannot be upgraded.
