A:Answer Hello,
Upgrading Sony computers can be more trickier than other brands; because they don't guarantee that 3rd party RAM will work. I'm sure you've done this; but download CPU-Z and study the current RAM you have very closely. Study the timings, CAS latencies, ect- write all that down- and then try to find RAM with the same specifications.
I've done some research for you and I believe this memory module will work (according to Crucial) you need module "CT3665140".
It is a 8GB module that you can run in dual channel mode; giving you the 16gb of RAM upgrade you need.
Good luck!
