Sorry for the screen pic in advance. I have Ryzen 7 5800XT with an asrock b450m/ac, 2070 super and 850w psu. I have PBO enabled and adequate cpu cooler, runs about 70c under load. I am having an issue where my cpu is constantly downclocking to base frequency, 3.8ghz then back up to 4.7ghz. I can really feel it in games. My cpu line in 3dmark and other benchmarks looks like a pulse chart. Could this be due to inadequate VRM's on the motherboard?
