I try to test the undervolting with my 11x RX580, Asrock 110.

The card bios need to have the factory mV settings, like this (my original backup):

Until now I did the undervolting directly in card-bios, so I have lower wattage.

Also I have now flashed on the cards the second (lower mV directly in bios). I setup in dashboard/overclocking nothing than 1000mV than 800mV to test,
but the result is always the same, 2130Watt from Wall with 11x RX580.
smOS dont can to overwrite the modified bios, right?

Very interesting.
I have 72 cards. Rx580 8g Nitro + only. They run on Windows and i Was waiting for proper oc and voltage management in SMOS prior to switching.

All my cards have modded bios. Not the voltage but bios timing straps only.
Anyone has experience with modded straps ?
Today On Windows i get 31,5mhs eth + 980 mhs dcr @1000w for 6 cards. VCore @1150/900 Vram@ 2200/900

I should start migration by tomorrow, hope i will get similar résults

My best result with smOS (before the last undervolt, etc. update).
11x RX580 Sapphyre Nitro+ 8g, Asrock 110h. All cards has ASIC between 71 and 79, all card accept the settings below (850mV), rig runs since ~3 Weeks stable (I have smOS since 3 Weeks.)
I use risers only with min 4 condenser (ver. 006c).

Only ETH: 335mhs @ 1760W @ 1175/2200, powerstage 1 (undervoltage 850mV direct in card bios - without this I had +~25W/card)

Dual ETH + DCR: 329/6580 @ 2035 @ 1130/2200, -dcri 20, powerstage 1 (undervoltage same direct in card bios)

I will try the undervolting from overclock modul, but I think, I need in card bios the original factory mV settings - I must try it yet.
