Yes it's B Die, with active cooling, corsair fan holder + noctua fan modded onto it. It does 3800@ CL14 with 1.5v+ but I didn't want it to push this far Well could be ~48-52 degress, i can't remember. Also comes down which test is used. Could try higher trfc in such cases? I have the theory that a lower trfc actually hinders performance even when it's results in lower latency because the controller spends more time refreshing? So I just the default which always seems to be ~350ns regardless of speed.
