Hi,

 

I'm getting a kernel panic every boot, this started after i upgraded my ram with corsair cmsa8gx3m2a1066c7.

The macbook is a March 2009 model, MacBookPro6,2

 

What should I do?

 

Thanks in advance.

 

 

 

 

Below a dump of the panic

    If you've recently upgraded the memory, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts on the memory modules when handling them. If necessary, clean them with a mild solvent such as rubbing alcohol.

     

    The Apple Hardware Test, though generally unreliable, will sometimes detect memory faults. A negative test can't be depended on.

    I'm using the original memory as we speak, the weird thing is that its functioning normally.

    Have tried serveral different memory modules, all of the corsair brand, but all with the same error.

     

    I also tried one of the old rams and one of the new one but also without any success...

    If the new RAM doesn't work, you'll have to return it.

    I understand, but the strange thing is, the previous modules I used also had these problems.

    Is it possible something else is going on with my Macbook?

     

    So a recap:

    currently using the default modules. (4gb total)

     

    Previously used:

    Corsair Ram: CM3X8GSDKIT1066

    Corsair Ram for Mac: CMSA8GX3M2A1066C7

    Both with the same Kernel Panic

    If you have no panics with the original RAM, it's almost certain that the third-party RAM is at fault. I suggest you make a "Genius" appointment at an Apple Store to have the machine tested. There's nothing more I can tell you. Good luck.
