Besides checking it with another power supply and making sure Asus recommends the ram, I don't know what to say. I have had very few problems with Asus motherboards but it does seem to point to instability with the voltages. Could be a power supply or the motherboard. The temps seem a little high to me but I am not running your class of CPU, just an old FX8350 @ 4.01 MHz on a Asus Sabertooth 990FX R2.0 with 32GB of ram. You might contact both companies tech support and check to see if anyone else on the Internet is having the same problem.
