You can also keep it, in case you ever have to send the MBP to Apple, as it can happen, they replace the upgraded RAM upon return with the original amount of RAM you purchased the MBP with.
Why is this? I would have thought once you've purchased the MBP it's yours to change without voiding the warranty or does increasing the RAM void the warranty?
so, I just got an Early 2011 MBP and upgraded to 8gb RAM myself.
Just wondering.. any suggestions on what to do with the leftover 2x2gb sticks?
keep em. you never know...
I use them as backup just in case my 8GB rams fail.
could you use the MBP ram in a desktop if you build it yourself? Or do desktops use entirely different RAM modules?
