I have heard of one of these  A1347’s  having  10 GB of Ram installed;  how is this possible?

This system has two RAM slots which supports 2, 4 or 8 GB modules. You can mix them so in this case the person put in a 8 GB & 2 GB = 10 GB. Not sure why they did this? Most people just put in two of the same sized modules so here two 8 GB would have given them 16 GB of RAM which is the limit for this system.
