--- Comment #4 from bednarczyk.pawel@outlook.com --- For whatever reason the below configuration works fine:
OD_SCLK: 0: 852Mhz 800mV 1: 979Mhz 825mV 2: 1106Mhz 850mV 3: 1233Mhz 875mV 4: 1360Mhz 900mV 5: 1485Mhz 925mV 6: 1575Mhz 1000mV 7: 1631Mhz 1050mV OD_MCLK: 0: 167Mhz 800mV 1: 500Mhz 825mV 2: 800Mhz 865mV 3: 1000Mhz 1000mV
Note, I am never hitting P7. Oddly enough, if I leave everything else constant and change memory state 3 from 3: 1000Mhz 1000mV to 3: 1025Mhz 1000mV, I am hitting the same issue with memory pstate getting stuck @ 0 (167Mhz).
