I have MSI 580s running on standard firmware, didn't need to modify the bios. Managed with the right script after few hours of tuning to get constant 580Khs and 28Mhs. Fan running at 55%, temp not going above 60C.
Honestly I prefer running on factory firmware with fine tuning.
I would like to see that as well. Is it 8GB card? Power consumption? Share your findings with community.
