    Hi guys,

    Just got my new macbook pro last week, been having some problems ever since i changed my ram to Kingston 1066MHz DDR3, supposedly to be compatible with the MBP.

    I have experienced horizontal lines of flickering and freeze of my entire system, which requires me to do a hard reset. I have recorded a video of it here.

    I have also experienced similar type of freeze, but the screen pixels just cluster together at the top 20% of the screen, much like this.

    I have ALSO experienced my keyboard totally not responding when i try to recover from a password saved screensaver!! The mouse is working fine, but the system just can't detect any keystroke input, forcing me to shutdown forcefully again!

    I don't have time to send in my MBP as i need to work on it, and cannot do without a machine, any ideas how to resolve this?

    May i also know which rams are compatible with Mac?

    i also have the same problem. i hear that what you need to do is switch one of the 2gb sticks with the original one. something about non apple ram doesnt have the memory management needed.
