Hello.
First sorry for my bad english.
My RX 5700 still runs at 75 Hz while idling at 1750 MHz.
Switching to 74 Hz or less doesn't change anything (only 1 Monitor connected)
Only at 60 Hz does the Vram drop to 200 MHz (but that can't be the solution)
Since the problem persists, I found a HowTo in a large German PC forum:
https://www.computerbase.de/forum/threads/howto-vram-taktet-nicht-runter-loesung-emittel-cru.1986961...
However, AMD needs to be able to do this in the driver himself instead of the user resorting to third-party tools!
The problem has been around for so long and it keeps reporting and nothing is done! (nvidia had the same problem but fixed it)
So please have a look at it again, it's just unnecessary power consumption + heat / noise.
You would make many people happy.
Thanks in advance :)
