Im thinking this is 100% hardware related. Different regions get different hardware. I changed memory sticks out with Gskill 64GB kit 2800Mhz part number F4-2800C18Q-64GRS with a Jan 2016 date code on the sticks. Immediately went to fast boot disabled and it stayed that way, changing it did nothing. Could not roll back either with the new sticks in. Ended up in a mess, complete tear down to remove CMOS battery to reset. Would still not roll back stuck on 208 with all sorts of weird issues. Put original memory sticks back in and it went straight back to where it was working perfectly with BIOS 208. Rolled it back to 206 using cmd prompt no date trick without a hitch. More about it in the fastest memory thread.

At least hardware had me joining the rest with problems. Just changing the memory put me in the same boat. Going back to the stock memory and All was good again like pigulici posted, just add a couple of seconds to the boot time going to 208. I got the slow start with the power cord plugged in Jason. it stays plugged in most of the time. If I unplug it there is no change. Going back to stock memory put me back in the OK category again.

Mine come with 8gb(samsung), I just bought 2x8 ddr4, but with same cas/ras(corsair), in a couple of days I will get it, wonder if it will work, after all I read here...
If you go to having problems it will go to further suggest hardware compatibility problems issues.
Jason. Sorry friend but I cant follow you. You posted up that you changed all of your ram to 4 sticks of Kingston Hyperex 2400Mhz, Now that is different? To try and make a method to the madness information provided has to be accurate. I really am trying to follow you and what you are doing and when but find it impossible for my obviously limited mental capacity. Ive lost just how many of these machines you have, and how many are out for RMA and whether you are talking about one of 3 you have posted you bought or someone elses. Makes my head hurt and that is no easy task.

The power adapter was never unplugged on mine when started with problems. Changed Ram problems start, put back original, problems stopped. So long as I had even two sticks of the Gskill in I had the slow boot and inability to change to fast boot and inability to roll back to 206. Put original back with never having unplugged the power adaptor and it was like nothing had ever happened instantly.
I upgraded 2 G752VY with each 32GB RAM, another G752VY in RMA, For Asus Service representative investigation for the BUG that i REPORTED. @justintime
You cannot understand English? That's your problem not mine. I just share one possible temporary solutions. You brick your own G752VY not mine. I have more than 6 years Experience on services and 0 record of Bricking any device.
I successful changed the RAM in clean room lab with anti-static tools. Up and running with no different condition than stock condition. only speed improvement with faster RAM. That's it! End your hates on people, try to understand before voice out your stupidity.
