Suppliers: your contract must-haves

Hot take incoming: undervolting bought me 12% efficiency for a small hashrate haircut, and I'd do it again. Anyone measuring something different?

Genuine question first: a small test rental before committing has saved me twice now — watch the shares land at your own pool first. Anyone tried the opposite?

Good thread this. firmware updates over USB first, OTA only after you trust the supply. Learned the hard way. Curious what the group thinks.
