MacBookPro won't restart after RAM upgrade.

Texte:

I have a late 2011 MacbookPro.  I upgraded the RAM from 4GB to 16GB Corsair today, but the computer would not restart. It would get to the Apple logo, then freeze. Whenever I run the diagnostic test on either one or both of the new RAM cards, they pass. However, I can't seem to load the operating system (even in safe mode) with the 16GB installed.

I just re-installed one original 2GB card and one 8GB card together and the computer started without a problem, even though the cards are from different manufacturers and of different capacities.  Yet, using two 8GB, it freezes.

Thoughts?
