Mid 2012 13" 2.9Ghz - Single Chip 16GB DDR3L ? Technically Detailed Answer Please.

I have a mid 2012 13" 2.9Ghz where the "bottom" sodimm slot is causing instability when it is full - started 2 weeks ago with the stock 2x4GB chips and i tried to upgrade to 2x8GB but the instability was still there. I read on another thread that removing the bottom chip (the one closer to the keyboard) could prevent the system crashes, and it seems to be working...

 

Now my question is: Is it at all possible to get this mac to recognize a single chip of 16gb such as: http://www.crucial.com/ProductDisplay?urlRequestType=Base&catalogId=10151&categoryId=&productId=5745...

 

Has this been tested? or is it just technically impossible? Can someone explain why?

If it does not work, what happens? Is the 16GB downgraded to 8?

 

Thanks, gotjosh

I think this is a pretty definitive technical answer:

- Correct. The important point is that while Ivy Bridge does support 32 GB, it only supports 8 GB per module.

If the hardware of the logic board cannot support more than 8GB per module, then there is no use trying the 16GB module. Can anyone confirm this, and / or share links to the technical specs of the Ivy Bridge to really put this question to rest? Wikipedia article does not mention a per module limit: https://en.wikipedia.org/wiki/Ivy_Bridge_(microarchitecture)
