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.
Be extremely careful and immediately delete anything that is not yet published by the Phoenixminer team itself.So far we are up only to 5.8c and in their official website which you can find in the first page of this thread 5.9b is not yet released.Probably you have got some malware and you need to delete it right away.
If you made a typo and mean 5.7b you should upgrade to latest version 5.8c and use MSI Afterburner to change memory clock,core clock and fan speed,these are all needed to be modified in order to get the max from your card.Still if you have a 5.9b definitely is malware and you need to delete it right away.
