I added code to trim my supply and the good news is that it looks like the board is stable at 35GH/s at 0.975V. To get any faster than that I need to get over the max 1.050V my supply is able to put out (to do that I need to disassemble the cooling and change a sense resistor - not terrible but it is a hassle).

A single chip (the board has four) almost works at 1.050V/40GH/s. If I run all four then the supply under load drops to about 1.030V which doesn't work too well.

Need to validate this on more than one board of course

It's useless to operate any PS on border limit power, since power flicker will reset your boards...

Use 2 or more...we have such solution if you have no clue...let me know.
