SO , I`m using the last version of Phoenix miner (5.3b) and some blockchain drivers (17,4 - I think) for my AMD $X 470 . But I cannot undervolt my cards and they drain a lot of power from the wall . With almost 200w more than claymore used . How can I fix this ? Thanks
It' not possible to undervolt with old blockchain driver!
AB or miner can't do a sh*t to undervolt... and you can't use OverdriveNTool with old driver.
Solution:
1) update windows and use newer driver like 20.11.1
2) use SMOS
