Probably a bug with power saving. All you had to do is to select manual tuning power option and then unroll the greyed out submenu which is not immediately apparent. There you would check max speed instead of the base speed.
I have to do this for VRAM but for core clock I don’t have this issue















I’ve just done it yesterday for the Expedition 33 as well :D But I’ve used it for other games previously, it works surprisingly well on RDNA2.
