i noticed when going too low on the power limit the CPU Core clock will start going crazy while mining jumping rapidly between different clocks rates, we fixed it by increasing the power limit, is that something anyone experienced ??
It's normal, GPU needs power to maintain some clock, so if you didn't deliver enough power, you'll see unstable clocks, the GPU is trying to achieve more, but it'll be limited by power.
These 3060tis runs good at slower gpu clock, my 3060ti runs with -502 core clock, + 1100 on memory and 52% Power Limit, this is the best I could hit with my card, doing 61Mhs solid stable
You can try do reduce core clock, reduce power limit and your card will save some energy
