Got a new motherboard that can run up to 8000MT/s. The ram however can only go to 7200MT/s, any higher and it errors out in HCI memtest and Testmem5. I have two Noctua 80mm fans ziptied together on top of the ram sticks, but TREFI won't go any higher so decided to instead run VDD at 1.65 to get CAS down to 30 from 34.
