Hi Phoenix!
There is a bug in PM4.9c + 20.2.2 drivers (Win). -mclock doesnt work for polaris cards with Samsung memory onboard (probably when use RX5700 as a main card and other cards are Polaris)
And a feature request: to give an apportunity to switch -tt memory or chip temterature dependent (very useful feature for Navi cards where memory is much hotter then chip and a goal is to control memory temperature)
Thanks in advance! Nice to see you back again!
-mclock stoped to work on polaris a long time ago. I didn't remember in what drivers it worked...
