Would it be possible to run the C1 at a lower rate by only powering some of the hashing boards? I have a S3 that had a board go bad in it and I was able to run it for a while on only one board until Bitmain was able to get me a new one. Here my main concern would be shutting down half the boards for a while during a day, when the circuit I will plugged into will need to power something else. 15 amp circuit, and this thing look like it will be drawing around half that, maybe a bit more.
It's like a S3 cranked up really high on frequency. And more dense on blades to get the 1T.
I am sure it is not recommended but it seems like you could lower frequency to S3 levels and use 1 per blade (2 blades have fan controller using on them so maybe takes more on them).
Personally I like having all 8 powered.
