macbook promemorysleep-wake
I have an early Early 2011 MBP, which I installed 16GB of RAM in, despite the fact that Apple claims the maximum is 8GB. This is a hack which is known to work, but I'm having some trouble with hibernate as a result.
It seems my sleep image is only 8GB, despite the fact that my RAM is 16GB; consequently, if I lose power while having more than 8GB in memory, safe sleep fails.
Any ideas on how to correct this?
It's not possible to use RAM running at 1600MHz in your Macbook Pro 8.2, because it's not supported by the processor.
Your Macbook Pro has the Intel® Core™ i7-2635QM Processor which only allows DDR3-RAM running at 1066/1333MHz according to Intel. (see link for official specs)
While the 2635QM processor does not support 1600MHz memory, it does support 16GB RAM:
You may want to rule out a graphics card issue, which impacted select 2011-2013 MBPs:

And if you haven't done so already, run Apple Hardware Diagnostics:

A guess
See whether the problem is reproducible with compressed memory disabled.
If that's not a workaround, please vote down this answer and leave a comment.
