Hey taserz...thanks for doing this!
I have a mix of old and older S9 miners. One is an 11.85t, one 14t, but most are 13.0-13.5t. I haven't tried your process yet because I have new power supplies coming. They're modified 2450w HP units from Amity Labs in Oregon. I have cheap power in Washington State
My question concerns the oddball miners I have. Is this just trial and error with the overclocking or do you have some specific guidelines for where to start with which machine? I'm eager to try the 920 or 930 packages, but of course I don't want to burn anything up.
Also, were you able to set up the software so each hash board can run a different frequency (mentioned in post 42)? There's some guy selling S9 firmware on eBay that claims to be able to change the frequency per chip! His "dev fee" is 1.8% though...
