901 works great for power comsumpion but in my case it turned out is unstable because a firmware issue:
As you can see works great with 113-2447LHS-UDB VBIOS (same Sapphire Pulse model) while both cards with 113-2447LHS-UDG needs higher memory voltages.
I’m looking for a way to flash VBIOS to confirm my theory but seems like the AMD tool does not support the GPU
