Q: Mid 2012 MacBook Pro 13 16GB RAM Upgrade

Read your user manual.  If it has instructions for replacing the RAM, your MBP warranty will still apply with exception of the RAM.  The RAM will be covered by the manufacturers warranty.

Ciao.

Frankly what are you doing that needs 16 GBs of ram?

Sig, greetings:  Don't you understand the importance of bragging rights? 

Ciao.

Ahhh!

8 GB must be enough for that. However, if you feel that your computer works slowly with 8 GB of memory, you can buy more RAM. On a MacBook Pro, you can modify the memory and the hard drive without voiding the warranty, so the warranty won't be voided just by adding memory

I've 16GB of RAM and find that I use most of it much of the time - primarily because I have 4GB in use for Windows 7 Pro 64-bit under Parallels. A restart will free some up - but once I start windows... watch out:

This is after a fresh restart, with all of my 'necessary' apps open - in a few hours, that 'free' space will diminish to about 400MB and my page outs and swap space will increase.

If only I could have 32GB of RAM in my MacBook Pro...

Note the display the clintonfrombirmingham has posted.  How does your MBPs RAM usage compare?  The fact is Clinton is not representative of the average user so you have to evaluate your needs and determine if more RAM will indeed be beneficial.  I suggest that for the overwhelming majority it is not.

However since it is relatively inexpensive, no harm will be done by the increase of RAM but do not expect the results to perform miracles in a performance increase.

Ciao.

Hey, if I'm not 'average' then what am I? Sub?

"So does it void the warranty? Also bragging rights"

Does not void warranty and gives bragging rights definetely.

No, installing RAM (and hard drives/SSDs) doesn't void your warranty - in fact, here's the Apple Support page that actually walks you through the process -> http://support.apple.com/kb/HT1270?viewlocale=en_US.

If you haven't already received the 'gift' just make certain that the giver knows the exact specifications for your model.

I was not referring to any RAM manual, but your Macbook Pro manual.  Since I do not have the latest one I can only reference mine and all the manuals for the three MBPs that I have give instructions on RAM replacement which indicates that it does NOT void the warranty (200, 2010, 2011) but only on the RAM.  If in the process of swapping the RAM you damage the MBP, then that damage will not be covered by the warranty.

I too have 16 GB RAM in the 2011 MBP so that gives me bragging rights, but the important point is that the cost was about $90.  A couple of years ago the cost would have been over $1000.  Since it is very rare that I use more than 8 GB RAM, an increase would have been fiscally unsound two years ago, but at current prices the increase can be justified far more easily.

Based on what Clinton has described over time, his MBP installation looks like an octopus with the various paraphernalia attached to it.  'Normal' users might have one or two items attached (I usually have none) which suggests that there would be less demands on the MBP.  If one chooses to keep many applications open, then additional RAM can be useful, but note that is under the users control. 

Ciao.

Clinton, regarding the 'average user', you can take it any way you want to, I simply will keep that point confidential. 

Best regards.

That is, indeed, an apt description of my machine... but as I migrate from FW 800 drives to Thunderbolt drives, it's less 'ocptopussy'...
