It works, VRAM returns back to minimum in idle. I did not know about UVD clock bug and saw people are not getting it fixed, it is probably on AMD side. Just one small question, what is Supports ACP/ISRC option in HDMI settings. It comes turn on when I start CRU and I left it that way. I saw that was mentioned on the forum, but I could not find explanation what is that exactly, what is its purpose.

ACP is audio content protection, and ISRC identifies what song is currently playing. Windows does not use this, so changing it would do nothing. This was intended for DVD-Audio and Super Audio CD players, so I don't think anything uses it anymore. The HDMI 2.0 specification doesn't even mention it.
