Hi all,

I have 13 x RTX580 4GB cards, I can still have 5.4c version running, but the hashrate is no more than 9.3MHs per card. Is there any way to still use them or are they condemned to die?
Last year I was mining @ 31 per card, now is less than 1/3, is the power consumption also reduced towards 31MHs or it's still consuming the same but the result is 1/3 (9.3MHs) ?
