I have this ram with the MOB. (with 2700x)
I am unable to get it running at 3200. In fact it runs way under.. everything works perfectly but my ram.. hugely disappointing in wasting money on it tbh. Avoid it.
GSkill emailed and just said it wont work with a threadripper.. even though its a 2700x.. not a threadripper.
So don't expect any help from their clueless tech team.
