That was one of the few that I thought could handle the 64/128 part. However look at the output filtering: It's roughly the same if not a cap or two larger as what you'd find on x299... which is a higher voltage and thus has lower amperage requirements. I have yet to find a back of board shot but unless it has a ton of SMD AL-poly caps back there that board would still struggle with the ramp described in the thread. Even then I'm not sure the socket resistance wouldn't cause enough V-droop to cause a crash anyway.
