Yes it only happon in Mac 10.11.6 but not in Mac 10.9 or 10.10.5.well I put in my pny rama same prob and when I put in the ram that came with MacBook Pro sometimes.
after I download Xcode shutdown the MacBook Pro and try to boot back up with Samsung Eco 850 same prob but maybe image tore settle smc. Boot time in Mac 10.10.5 is a lot. Faster.

I guess I am still old school. Only paired RAM for me. It is the best was to assure performance.
In my first computer it only had two slots for RAM. I purchased the second 1mb RAM chip and it was the same as the first.
My second had 4 slots in 2 banks the banks where keyed alike. I had to have the same ram in each bank.
But it had to be the same speed in both banks
So I have never really played around with mixing ram.
Now that Apple has adopted PC archictecture it would make sense that you need to pair it. You may be able to have different size chips in each slot but I think for integrity they should be the same type and speed.

Why was having Geek Squad put it in a big mistake.
Keep in mind, if you have Apple care or warrenty if you do it your self they are voided
