Hi! Exactly the same board. The Brand was a different obscure name but its all Ali Express anyway. But yeah, exactly the same problems. I tried samsung, crucial and ripjaw RAM and all the same. Underclocking by I think 600MHz completely solved it.
I have the same board and went through multiple replacements, changed PSU, drives etc. Its basically a cheap design RAM issue. Lucky for me and you this can be "solved" with underclocking the RAM, for me from 4800 to around 4400. Had multiple freezes and crashes a day before but is now stable for 5 Month.
