Can I use Kingston RAM in a MacBook Pro?
Solution 1:
I upgraded the memory in my Early 2011 MacBook Pro from 4 GB (2x2) to 8 Gb (2x4) using the Crucial site, and haven't had any problems at all.
For the record, I also did the same with a brand new iMac, swapping out both memory modules with 2x4 GB from Crucial.
It worked out to be about 1/3 of the price that Apple charges for the same memory.
Solution 2:
Any brand of RAM will work, so long as it matches the specs the computer is expecting. (That would be the "DDR3 1333 MHz" part.)
For the most part, Apple uses standard PC hardware, so there's no more restrictions on what types of parts will work than there would be on a non-Mac.
Solution 3:
If you aren't sure just use crucial.com's system analyzer. Any RAM brand is fine for the most part, but stick to the more well known companies.
