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

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!
