I mining with this modded firmware and I try to setup 600M with 18 Voltage (for other 3 chains setup is Use Global) but HW getting worst for me. I have APW3++ 1600 W Psu with 220v. So what I missing?
Your just going to high your asic chips cant handle 600 that is why its getting worse
My D3 is 19.5 gh/s it should be handle it with 562M I think.. But I'm trying all possibilities of voltages but HW and pool rejects being is very high at the same time.. 21 gh/s is enough for me I don't want to use stock firmware..
it doesnt mean that it can handle even 19.5 gh/s it depends on luck, in your place i would lower frequency
