1 Why cant I upgrade the RAMs for MacBook7.1
i got two 2G ram but failed to upgrade to 4G but i couldn't . i was only able to reach 3G. one of the original rams has to be installed for it to work.
so i decided to try different ones after reading lots of forums on here , I got two 4G ram however it refuses to boot with them both. Only one of them with the original 1G ram.
I have tried all possible combinations and cant get more than 5G
Its very frustrating to read that some are able to get it to work. Any tips??
what am i missing, why does it need the original 1G ram.
Macbook 7.1 mid 2010
Ist dies eine gute Frage?
