Seems to be a duplicate of #162

I created a new ryzen-smu-cli.exe with the proposed workaround, but the way I understand it right now it could very well cause the program to just break on other chips.

I've attached that file, which you could try and see if it works for you. It needs to go into the \tools\ryzen-smu-cli directory, overwriting the existing exe file (or just rename the old one to have a backup).

Absolutely untested. I'm not going to use this as a new version as I really think it will cause problems with other Ryzen chips.
Let me know if this worked for you if you can.

Same problem still happens with the new ryzen-smu-cli file. The core optimizer could be adjusted with the alpha 4 version but when the official version released, CoreCycler could not set core optimizer values.

Below is the new log generated by CoreCycler.

Does it work if you copy over the whole \tools\ryzen-smu-cli directory from the alpha4 version on top of the one from the release version?

The alpha4 still used the WinRing0 system driver, which was replaced with PawnIO in the release, because Microsoft began to flag that driver as malicious and blocked it.

Apologies for the late reply to this issue. Yes it does work when I copy \tools\ryzen-smu-cli folder on top of the one from the release version.
