Hello. I've got a Macbook Pro 13" mid 2010 - 2,66GHz Intel Core 2 Duo - RAM 2+2GB. I'm trying to change the RAMs with a pair of 8GB Corsair ones. Apple actually says my mac can mount a maximum of 4+4GB, but hearing and reading around seems it can mount up to 16GB. It doesn't get stuck immediately and doesn't make sounds but it gets stuck at the "grey loading page". I tried to do the PRAM reset and try the two RAMs separately. Re-mounting the old RAMs it works good. Any idea? Thank you.
