My s9 is back online....now to raise the hash rate again!
MINE ON WITH KANO-SAN!
The s9 b23 at my main farm is also back up. Sorta.
Replaced the control board with one from a batch-13 (non-auto tune) that I had been using for spares. Works perfect and even better yet now that Frankenstein once again has Freq. control Smiley
Ohhhhhhh, I didn't know that was possible - non-auto tune control on a new S9.   Any chance you have other older controllers around?  Would you be interested in a swap?  (newer for older)
Wasn't sure if it would work but so far the combination is very happy.

Sorry, that 1 s9 was my only spare. I have s9's from batch-1 on up but am not about to cripple the older ones by dropping in auto-tune controllers...
Bumped the freq up from 575MHZ to 600 and hash rate climbed from ~11.8 up to 12.9THs. Happy happy happy!

I understood from the S9 thread auto tune is in software - you can drop in the fixed frequency firmware from Bitmain and fix the frequency lower for the auto tune S9's...only useful if you want to reduce temps (and hash) from what I gather
