So I'm bad luck then, I have 4 gigabyte vega 56. Overclocking SOC to 1200 not working stable, miner stops working, miner freezes, pc freezes. Tried setting those numbers from C0,D4,01 to 38,C1,01 (for 1,15Ghz) but no luck SOC stays 1200 (1999). Increased Voltage for both GPU and memory, it works like stable, get about 2% more h/s but get about 12% compute error, which I never seen before.
