No, they auto-tune during each startup/reboot. Been that way for many batches now.
Thanks for the heads up.

The 0.1 W/Gh/s is really nice but I wanted to use less power/watts, then the stock ~1300watts.
You could always hack the firmware or run 2/3 boards for (roughly) 67% of the power consumption. I am certain you would find lots of takers for a single (working and new) hashboard, judging by the amount of boards that seem to be breaking.
