The RX 6600 XT Mines under Hive OS. Beta Version only.
I use the latest Beta OS of Hive and get 30.33 MH.
The OC settings do not work yet, and the card without any OC settings pulls 81 Watt. That is without the system which is at 20 Watt.

got 2 x powercolor red devil with samsung memory.
used the same oc like you, i’m getting 30,38 mh’s.

im on 43w

Will this only work in the beta right now?
someone tried latest phoenixminer…?

PhoenixMiner v5.8b (implemented optimized kernels for AMD RX6600XT cards…
