okay the boards work with

all S19
and t21
and s21


When you under clock it allows you to disable any of the 3 boards

it also allows as low as 50mhz freq and 12 volts if you do manual.

you can also go way high like 600 freq and 15 volts
and that are the manual settings

more than that you can autotune from 60th to 300th   on the t21 I have.

the flexibility is huge much more like a gpu from the old days of mining.

You also may find you a board that allows really low settings and another board that allows high settings.

Right now in northern SK I can climate control down to whatever I want easily and about 15 degrees C seems to work well and have been using the Vnish 60-62TH profile on about 20 machines and they have been rock solid.  

I have brains a go and got greedy the first go and landed at about 65 yet temps seemed really reasonable with the low ambient so I let it eat.    Made it about a week and one card went down,  by the end of the next week another was down and limping on the last.
Figured well this is garbage gear I’ll give it another go.   Lowered it to very similar hash rate and draw as my Vnish settings.
Ran rock solid for 2 weeks straight.  I thought ok this might be the ticket.  I wanted to like it!   Then boom.  Sum bitch lost a fan and was merrily tuning away for I’m not just sure how long loading up to 80 degrees then unloading it to a reasonable temp and then back up.
Still haven’t looked at the machine or thought about replicating why it didn’t shut down.
Nonetheless 3 more hash boards down.
