I recently bought the Asus N550 jv with touch screen and 8 gb. The salesman told me I could easily upgrade the memory replacing the the 2 x 4gb by 2x 8gb. I bought the Crucial memory Crucial CT102464BF160B 16GB (2 x 8GB) 204-pin SODIMM, DDR3 PC3-12800 Memory Module B&H Kit. Now the laptop doesn't boot, sometimes, after several tentatives, it will but once shut down again, it will not boot...individually, the memories work fine and with 4gb and 8 gb (12gb), it's ok too. Just the full 16, is showing issues. When I go to the bios, there is no configuration of ram frequency in this laptop, so I don't know if I adjust the frequency, it would solve the problem but I don't even know how to find the frequency config in bios...help please!
