Please let us know if you have any problems or questions related to PhoenixMiner 5.6b.
I tested with Linux AMD driver 21.10.1247438 and 6900 XT.
Kernel version is 5.11.16-arch1-1 . With this kernel version, there is no over(under)clock control. Only powercap can be changed.
In the below scenarios, the power cap is set to 150W.
1. 5.5c + 20.45: ETH speed reported ~59 MH/s. Effective at pool ~59 MH/s.
2. 5.6a + 20.50: ETH speed reported ~59 MH/s. Effective at pool ~59 MH/s.
3. 5.6a + 21.10 + clkernel=0: ETH speed reported between 59 to 61 MH/s. Effective at pool ~60 MH/s.
4. 5.6b + 21.10: ETH speed reported ~64 MH/s. Effective at pool
~20 MH/s.
