@nitram100 have a look through my previous posts regarding my o/c settings they might help mate. Minor adjustments aside, for circa over a year now I have been running my Vega 56 Pulse as follows... MHz / mV... State 0 - 852 / 800, State 1 – 1012 / 900, State 2 – 1162 / 950, State 3 – 1292 / 960, State 4 – 1337 / 970, State 5 1502 / 980, State 6 1567 / 1015, State 7 – 1622 / 1020. A custom fan curve that maxes out at 2300rpm and keeps the hot spot temp at a max of 80 degrees c. HBM @ 935MHz and the power limit at 17%. GPUz shows the GPU core clock @ 1622MHz, having just checked Horizon Zero Dawn the game is running @ 1580MHz core clock. Furmark burn maxes the card out at 180 watts and all temps are well within specifications. I can max my card out to run at 1704MHz core o/c running 100% fan speed, borderline max temps and specifications if decibels are not a factor and that interests you, let me know and I will post the settings. I seen just a circa 1 to 2 fps increase going from my daily overclock to the max overclock on Horizon Zero Dawn stanting still in the same place. IMO anything over 1600MHz core clock on a Vega 56 is pointless, I never bothered flashing my card for the same reason.
