    I have a Core i7 2.66 Macbook Pro !5" with 4GB memory (2010). I just bought Corsair CM3X4GSD1066 (8GB). But I have few problems after installation:
    1) Usually I never shut down my mac, upon finish the work I just close the lid. But now every time I want to awake, I need to press the power button instead of just moving the mouse or typing anything. And i takes a longgg time just to have the screensaver password pop-up

    2) The macbook pro get super hot after I close the lid.

    3)I experienced 1 screen of death right while browsing after upgrading the memory to 8GB

    Can anyone offer suggestions or share their experiences ?

    much thx.

    1 & 3) You should remove/reseat the RAM and/or run some memory test to see if you got a bad stick of RAM; it happens....

    2) Generally speaking, the 8GB will be hotter than 4GB; in addition, is the MBP going to sleep when you close the lid? If it's sleeping, it shouldn't be getting hotter.

    I did as you said, I reseat the RAM and run the hardware test. The test result was good.

    I even tried to reset SMC.

    But, the most annoying thing is it takes me at at least 2-3 mins just to awake after I close the lid for a while. It only awake after I press the power button repeatedly. And when it awake, it has a progress bar, so it seems like it went to hibernate instead of sleeping.

    Are you sure thats the right ram for that model? I'm too lazy to look it up. You might try a ram checker utility to see if your stick is bad.

    Test RAM with Ubuntu Boot CD

    I recommend testing all new RAM with memtest. You find that on most Linux boot CDs, I use Ubuntu.

    Let it run for a night, if there are no errors in the morning your RAM is fine.

    The problem definitely lies the RAM. When sleeping, files are supposed to be written to the RAM, but somehow it fails and go to safesleep state. I will try to exchange the RAM module, and try again. If it doing it again, it means Corsair CM3X4GSD1066 simply is not compatible with core i7 2010

    Is this for sure true? I just ordered received 8GB of RAM for my 2010 MBP 13" but I have not opened or installed it yet. From what I understood it would not make the computer run hotter :confused: If it does, I may just return it without opening it.

    OP, I hope you don't mind the slight tangent :eek:

    try checking the cas latency of the ram,i forget the timings,but its like=cl 9.7.7 or something like that,your old ram will have it on it or check apple website under specs,alternatively,check you have seated it correctly,have to be very careful with static with ram,1066 is for that model im sure,
