I used to get this error after installing 8gb of RAM into my MBP 5,1 after I read Apple released a fix to enable use of 8gb instead of the 4gb recommended. I got kernel panics often and accepted it was due to the extra RAM.

I removed 4gb of the RAM yesterday so only 4gb remained, however I am stil getting kernel Panics. Can anyone help?

Here is one of them:

    Hi r,


    Why not return the RAM for compatible RAM?

    You said it doesn't work properly with your Mac. If RAM is causing kernel panics, that means it is not compatible. Or maybe I'm not understanding something you said?

    I guess my question is: Why is it causing kernel panics? The RAM should be compatible with my mac because it says that it is compatible with Macs. My system detects it and I did the Rember test and it says it was functioning properly.


    Exactly which brand and model of RAM is it and exactly which MBP do you have?

    According to your kernel panic it seems to have a beef with your AirPort driver. Have you made any changes?


    Your MBP can take 8GB max of  204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM.

    IF this is what you have ordered:

    "Komputerbay 8GB (2x 4GB) DDR3 SODIMM (204 pin) 1066Mhz PC3 8500 for Apple 8 GB"



    You should read the reviews by other shoppers first... NOBODY likes the memory Komputerbay sells. Most claim to have lost data, have kernel panics, and crashes, etc...


    I would return the memory for a refund


    It would be best if you buy brand name Apple certified memory... (ie: Crucial, Centon, Buffalo, etc...)

    I have a MBP 5,1 Late 08 Model with 2.4ghz. The RAM is from KomputerBay a seller on Amazon UK.


    I haven't made nay changes to the Airport Driver at all, however the kernel panics have changed in nature. Before they used to act when I was using the computer, and in the log it usually mentioned Google Chrome, i guess because I was using it. After removign 4gb of RAM, they now occur only when the computer is opened from sleep, this must be why the airport driver is mentioned as the computer is accessing airport upon wakeup?


    As I said, the RAM is incompatible. I would return it for a refund and get compatible RAM.
