my second question is if i use -cvddc in claymore command for example 820 and core voltage 920 in consul the gpu work with which value? 820 or 920?
Claymores readme:
-cvddc set target GPU core voltage, multiplied by 1000. For example, "-cvddc 1050" means 1.05V. You can also specify values for every card, for example "-cvddc 900,950,1000,970". Supports latest AMD 4xx cards only in Windows.
Note: for NVIDIA cards this option is not supported.AMD only Windows, NVIDIA is not supported.
