I just did a Ryzen 5900x build with the Asus Crosshair Dark Hero MB and .Corsair Vengeance LPX 32GB (2X16GB) DDR4 3200 (PC4-25600) Ryzen Master states my max clock is 547 MHz! No changes have worked. I have the latest bios. It will not change speeds. In the bios it states 4300 MHz but in windows 10 it's running at 547 MHz. I tried over clocking with Ryzen Master and also with Asus TPU II profile since this pc is water cooled. Nothing works.
