Macbook Pro early 2011 16G Memory Upgrade I just purchased a Corsair 16GB Memory upgrade for my 2.4GHz 13" MacBook Pro, but I have not been able to make it work.

If I put both modules together or one of the modules alone the Mac wont bootup! 

If I put one of the old (original) 2G Memory modules and a new one the computer will work ok and will recognize the 10G memory.

Any advise will be greatly appreciated.

While not officially supported, 8GBx2 PC3-10600 modules should work fine. Did you try both the new ones individually with a current 2GB module? If so, I'm not sure there is an option other than getting replacement modules. You could try resetting the PRAM but that's a long-shot.
