    I am going with G.SKILL due to the very very positive reviews for it here and on NewEgg.


    and this:

    are both the exact same price but seem to be different as one has 197 reviews and the other has 135. Also the model #s seem to be slightly different so please forgive me I'm no longer the technically savvy person I used to be when I built gaming computers...what is the difference between these two sticks?

    Also I have a MBP 2011 corei5 with 4gb RAM which I believe runs at 1333 mhz will I have any benefits from getting faster RAM (1600 Mhz)?

    Lastly could anyone tell me which of these tool kits has the right scewdriver bit for my MBP?

    thank you in advance!

    For your MBP use the first one. That's the one I have in mine and have no problems with them.

    They're the exact same sticks, one is just labeled as PC10666 and one PC10600.

    I have one of them btw and they work perfectly in the 2011 15".

    Technically speaking, there is no such thing as PC3-10666 DDR3 RAM - it's an unofficial way that some manufacturers name their PC3-10600 DDR3 RAM modules, for obvious reasons - people think they perform better.

    PC3-10666 RAM is a misnomer that is derived from the peak transfer rate of PC3-10600 RAM (10667 MB/s). As long as the timings are the same, there is no difference between PC3-10666 and PC3-10600 RAM, as they both run at 1333MT/s (therefore, the standard name is DDR3-1333).

    I don't think there is really any benefit to going to 1600MHz RAM. The difference would be imperceptible, other than in benchmarks. You'll need a Philips 00 to open the computer.
