I found a solution for power consumption. Download OverdriveNTool and you can make every GPU like in Claymore
You are right... that's the best solution you can control the Core, Memory and fans in better way and change the profile as you want. Only taking care not to use a AMD Driver higher than 20.4.2... that's my combination of the swap I made.
20.4.2 + OverdriveNTool + lolMiner. So I can mine ETH and ETC and change fast the parameters when I want to jump to Beam all with the same miner.
