Failed Ram Macbook Pro Macbook Pro 15 Unibody Mid 2010
Chosen Solution Just bought 2 4gb RAM cards but they have failed to work. Place the old ones back in and they work fine. I bought the ones recommend for my computer. Anything i should do before installing them or are they likely just to be fully and need returned? Thanks P I agree with Matt. Make sure that you bought RAM with matching clock speeds (this will most often be measured in MHz)....
