what kind of results can one expect? we talking 50watt or 5 ?

Sorry found answer in original thread.

I am going to ping phil to give it a whirl since I know he has a few L3+. Sadly all miner are in a hosting facility except for one lonely s9 that is pos and been in warranty 5 times. But the OP thread it was 600w vw 800w so that is a 20% saving.

Just got a pm to read this

I have multiple L3+ with the undervolt tool

using just the jstefanop tool on freq 359 hash rate of 470 I do 667 watts with minimum volts on all 4 boards. using a corsair ax1500i titanium

this is a savings of over 100 watts.

So my first question is can this scrypt use a lower volt setting then 0xfe?
here is a 3 board unit with voltage tool

so after days no Hw's to speak of.

this is manual tuned to lowest volts on the tool and I use freq 359 since it gave me almost no errors
