I don't have any idea, but you may check your RAM installation and try to reinstall both memory modules again. I have added 16GB RAM into my MBP 13" 2012 only few days ago and everything is working flawless. I used Crucial dual-voltage chips. Your RAM should be PC3-12800 (1600MHz) supporting 1.35V power. Check if your modules meets this specification.
