So my r5 5600 can't even reach 4.4ghz, let alone 4.6ghz at all cores when running cinebench test or handbrake encode work. I already have pbo+co enabled and +200 boost clock override. I also noticed that my cpu keeps running at ~1.33v despite already applied co. My case is well ventilated and cpu stays 75~76c at maximum. My cpu is running on asrock b550m pro4 and thermalright ax120se. Does anyone know how to fix this?
