globalpowertune 4 seems to crash after a while and dont effect realy my watts anymore. i am on 812 watts for this 5 cards.

without any cards my board needs just 29 watts . so 156 watts per card right now .

any idea ?

i have no experience with flashing and got so much questions about "VRAM" , special polaris editor for some ram type, backup both VRAM and RAM , whats difference between 4 and 8 gb version ... bla bla bla you all know what i mean . after watching 4 hours of lifestreams for this - i thought the "out of the box" version from ethos is perfect for me.

under windows 10 - i got issues to even boot up the system with 5 cards.


could you post me some of your parameters and results for ethos-only-version to compare a bit - and see how i can lower the watts ? ( have to pay 0.29 USD here per kwh )

happy mining,
