I Just purchased a T520 4239 .. With 4GB memory. Of course I would like to fill it up to 8 GB.
I saw an old thread on the same subject some suggested:
The Kingston HyperX KHX1600C9S3K2/4GX .. Is still a good idea ?
Also, any chance I could load a pair of 8GB sticks to bring it to 16GB ?
Or use one of 2GB sticks that are in . With an 8GB stick ?
Solved! Go to Solution.

The pair of Samsung sticks should work fine. I'm running a similar Samsung stick (Amazon link) in my T420 right now along with the stick from the factory. Since you already have those, you should try them out in the T520 and then decide if you want to go up to 16GB. 16BG (2x8GB) is not "officially" supported, but has been known to work.
Bear in mind that any increase in RAM tends to have a few minor drawbacks. I feel these minor complications are well worth the performance benefits of additional RAM. However I also feel you should know about them. First, an additional stick will increase power consumption slightly as each stick draws a little power, this is often partially offset by the SDD or HDD spinning down more often and drawing less power. Additionally, more RAM will increase time for hibernation or hybrid sleep because the data in RAM has to be written to disk. Finally, if you are using a smaller HDD or SDD please remember that the Windows hibernation file generally takes up space equal to about 75% of the amount of RAM in the system, so 6GB for 8GB of RAM and 12GB for 16GB of RAM. If you use the hibernation feature, it is a good idea to make sure you have sufficient free space prior to installing the RAM.

I've been quite happy with my 8GB, but I imagine 16GB might make more sense with 4 real cores. Right now I'm sitting here with three displays (2 external + internal), about 50 chrome tabs open, an instance of IE open, many pdf documents open, many word documents, and email, etc. I have ~7.5GB of RAM "in use" as reported by the resource monitor (about 600MB of that is to run Pandora). So I'm close to the point of swapping to SSD. As this usage is about the most the machine sees, except when photo or video editing I'm ok with it being near its limit.

I think its beyond the scope of this thread to understand or discuss what you actually do or doing with all that open.
WOW is all I can say.
Actually, I can explain what I'm doing briefly. I'm a law student and right now I am researching the finer points of a statute and writing a memo on the statute. The memo is intended to be understood by non-lawyers. This involves having open the various parts of the official statute, guidance about what it means from official sources, cases pertaining to it, commentary on it, etc. It also involves having open links to dictionaries and a thesaurus so I can make sure it will be understandable by non-lawyers. In addition to the things open on my computer, my desk also includes a >250 page citation manual, some printouts, and a few style guides. At 6ft, things are a little crowded and there isn't much room for my coffee mug, I may need to upgrade to an 8ft desk.
