It seems to me like the cpu is not idling and I dont know if it's software or hardware related in my system. But when I go to 55% then the clock speed and multiplier increase to x20. Though if I have maximum processor state anywhere between 0% and 50% there is no change. I found if I set maximum processor state to 0% then cpu-z will show core speed of 1.7ghz which is also reflected in task manager, as well as the multiplier in cpu-z showing x17. Nothing I tried made any difference EXCEPT when changing windows power plan config.
starting in safe mode as well as disabling all services except microsoft services and rebooting updating drivers and chipset drivers from AMD website resetting bios config (though I am always using default settings apart from enabling secure boot and TPM, though have also tried not changing any setting at all) updating bios and trying many bios versions
Prior to me replacing the system board (it was another ASUS x570 board) I had tried: Yesterday I replaced the system board because I had some weird experiences which have now seemingly been resolved however the above issues still exist before and after system board being replaced. It seems that ryzen master might be looking at the effective clock but the voltage seems too high. AMD Ryzen master will show current clock speed at say 455mhz but current voltage is like 1.2v.
However, voltage never goes lower than 1.0v or 0.9v there. hwinfo shows the same clocks but the difference is "effective clock" can be as low as 50mhz on the individual cores. Again I am sure I've seen something like 800mhz here but cannot recall whether it was only in windows 10 or both win10 and win11. windows task manager barely shows low clock speed and never below 3.6ghz. But I am almost certain that I've seen slow clocks and low voltage at idle here It will go to 5.0ghz under some loads which seems normal. cpu-z never shows multiplier below x36 (3.6ghz) and voltage never below 1.0v. Then the PC was boxed up for shipping back to England as I Was moving back there.Īnyway, a few weeks ago I have my computer back and I immediately turned it on and ran updates. I dont think that there appeared to be any issue. I then upgraded to Windows 11 but cant remember what the clocks were saying at that time back in 2021. I recall being surprised that the CPU clock would reduce to an extremely low value when just sitting for example at the desktop. Originally in 2021 I built this system, ran windows 10 and all went well. Windows 11, ASUS x570 board, 2 x 8GB RAM, AMD 5950X, AMD 6700XT GPU
