Just installed my 2700X into an Asrock X370 Taichi flashed to latest 4.60 BIOS. The boost is not working particularly well on this board at this point. Loading up one thread I really only see it go up to 4.25 GHz, rarely at that, and it usually stays in the 4.1-4.15 range. With one core loaded it's at 42C and well under the PPT, EDC and TDC power limits in Ryzen master. Not sure how to make it go to 4.3-4.35 like it's supposed to, I haven't seen it hit those numbers even once under light one thread load.
I even manually plugged in the precision boost overdrive limits from the_stilt's mini review (1000W, 114A/168A TDC/EDC limits).
Anyone have any suggestions or am I stuck buying X470?
