It's not needed he uses Watttool

GPU 1180
Memory 1750
both running at 904MV

true that. I never go above 1180MHz for the core on the last phase and it's never over 925mv.
btw memory read intensive dagger-hashimoto doing fine on 850mv (total power from these 6 is below 920W in dual mining)

eth only is 816W:

Excellent settings. Thank you, boys. I am now graphics cards cloks 1180 GPU, 2100 GDDR5 RAM, - 48 mV, power limit +0. I now have 6 x 250 Sol / s = 1500 Sol / s and the power consumption is 880 W (measured by energy meter).

Zcash v 11 is doing quite good.

Undervolted 4 x cards I get 1046 H/s and 360 watts at the wall.

what software both of u use for that ?

Maybe MSI Afterburner.
You can also edit voltages in the drivers with AMD Wattman. I use the latter. You can set voltages and clockspeeds for multiple steps. not that interesting for mining but it is for gaming. But could also be usefull if you switch to a algo with higher load and temps. If you set a power limit it can switch to a lower speed step with lower clocks and voltages to save power. A custom bios would be nicer. But then you cant use the latest drivers.

With MSI afterburner you do have to option to change the values at the same time for similar cards. But the weakest card will be your limit then. Other cards might be able to run the same speeds at lower voltages or higher clocks at the same voltage.
