mv yes sorry.... Yes, as you said the static was added to the vrm…. it did increase k/sol some but gave more heat then wanted. I am looking at maybe building a separate vrm and bypass the current one or if it is possible to just swap some resistors and caps to change the output value. I have to first look more into the specs on the current vrm and trace how it is connected. I have so many spare electronics around here for parts that it shouldn't be a problem making a test board for the vrm.
I do know about the IOdrive and haven't looked into it to see what is going on.
As I said I only play with this stuff anymore and don't know how far I want to go with it, there are many other things I have going on that take up the extra time. My advice would be to put all your time into the voltage and leave the fan alone for now, the fan problem has a fix with a fan emulator but the voltage is the holdback of these machines, a voltage fix is going buy some extra time to make a profit but still as the difficulty rises even that wont help the miners profits. SO you could say the clock is running out.
The VRM is controlled via a PWM signal off of the ISL68127 -- it'd need to respond to that.. and unfortunately it's also hidden behind the one chip type on the board that is etched off. It's been etched off on all of their recent miners.
