I can't modify the overclock settings of my RX 6600 with PhoenixMiner 5.9b in windows.
Using AMD driver 21.11.2.
It's my oc settings:
-fanmin 50 -fanmax 50 -mclock 945 -cvddc 735 -mvddc 1150 -cclock 900 -amd
But nothing changed. (except Core clock)
What should I do?

System:
Windows 10 20H2
B85 / G1840 / 4G RAM
MSI MECH RX 6600 x 8 (Every card can work)
AMD driver 21.11.2
Run in admin privilege
Thanks.
As
ironmanred said, for the memory clocks, you need to set them near the maximum for Windows. For example
-mclock 1800 up to 1900.Also, I think
-fanmin 50 -fanmax 50 won't work as expected, because you need to set the maximum speed higher than the minimum. If you want to set the fans at
a fixed speed of 50% is better to use
-tt -50.
