Hello,
I couldn't find my answer on Bitmain's website.
Is it possible to change the frequency, to underclock or overclock, the S9-13.5TH/s and S9-11.5TH/s, that are sold at the moment on Bitmain's webshop ?
Thanks
No, they auto-tune during each startup/reboot. Been that way for many batches now.
This is simply not true! They run the autotune routine ONLY on first start or after a hard reset (possibly on other rare occasions), but definitely not after every restart be it clean or unclean. There is a flag set in the filesystem that triggers the autotune routine. Maybe somebody could point out where it is exactly - cannot remember off the top of my head.
