i have an Problem with my Ryzen7 1700X. When i'm encoding a Video with x264 or running Prime95 the CPU Speed drops perodically to 0.53 GHz. When the CPU is in Idle the CPU Speed is at 3 GHz. I think the 3 GHz for energy saving, but the 0.53 GHz is really low. When the Speed drops the CPU Usage also drops to 20 %, even with Prime95 running. Is this normal?


this Image shows the CPU Speed when encoding an Video with x264. The Ryzen Master Application says the same CPU Frequencies.
