    Right now I'm deciding to upgrade my ram up to 8gb but I'm not sure what to get.

    As it stands there are 2 different versions. One has 1066 with cas timings of 7-7-7-20 meanwhile there is the other which is 1333 with cas timings of 9-9-9-24.

    I've heard of compatibility issues with the 1333 but some users claims it works.

    For the record I have the April/spring 2010 version of the macbook pro 13

    Long story short. Higher frequency vs better cas timing
    Thanks for your help!

    I can tell you that I have 1333MHz DDR3 RAM in my early 2011 MBP and it hasn't caused any issues. It essentially comes down to lower CAS timing or faster CAS refresh timing. Ideally, you want RAM that has a higher speed, lower CAS, and lower voltage.

    Personally I don't think you will see any real world difference between the two so I would get whichever RAM is the least expensive (while ensuring that is completely works with your MBP). There might be benchmarks out there that show lower CAS timings is better and another that states higher frequencies are better but, when it comes down to actual real world performance, I highly doubt there will be any discernible difference.

    The 2010 MBP only supports DDR3-1066. You can buy 1333 RAM but it will only operate at 1066 speeds. Buy whatever is cheapest. RAM quality is pretty much the same no matter what you but so there is no point in spending a lot of money on it. I paid $30 for the 8 GB set in my MBP and it's worked just fine.

    >.> either way its ~40$

    its 39.99 vs 40.99 (both have free shipping and both are from newegg)
    But thanks for the tip. I wasn't sure if the 1333 would work or not that's why I questioned it

    prioritize speed over CAS timing unless you have some specific, explicit reason for doing it differently.

    1333 comes with the machine, so no reason to get anything different.

    Re-read the OP - he has a 2010 MBP 13. Those are still Core2 machines, thus they only run at 1066.

    but. if it is 1600 and only runs at 1333 how does it work perfect >.>

    but yeah I've decided I'm just going to get 1066. There really is no point in getting 1333 for faster speeds when it can't even use it.
    and with the 1033 it'll have atleast faster cas timings even though those are barely noticable

    Yes I did not see you had a 2010.
    but I had the ram just laying around it works perfect as there are no issues using it,just down clocks. Sometimes mac's and ram can be tempermental
