for those of you wandering if this is the auto tune version. This pic seems to be a stock 14TH model. so it will be set to hash at 650M frequency by the firmware.
Has anyone tried the firmware from 11-19? I'm giving it a shot on one machine right now. Curious how it is working for others?
Fan speed is much better handled for me - slight variations in speed, gently ramped, instead of the bang-bang controller in the previous autotune FWs.
Seeing much lower reported temps (~10C lower) but I haven't dug into whether that is just a cosmetic change or a change in setpoint for target temp.
Hashrate is good - 13.904avg over
3025 hours on a batch 1 set to 650MHz (theoretical speed 14.004):
Nice of you to jump in, and still be following the thread.
but please, can we discuss the elephant in the room? wtf is with these fans
They idle so low one minute, and the next minute my neighbors can hear them.
I have no issue with noisy miners, but this seems like it's just unrequired noise.
One minute they blast at 110% the next they are cruising at 25%. than boom back up again.
If they idled Higher, at 60% maybe? they would need to spike as often, and this would help with the noise greatly.
takagari - This is what I posted about re: the 19 Nov firmware. For me, this firmware stops the fan cycling and replaces it with much subtler changes in speed. Higher average speed over all, but barely perceptable speed changes.
It's a big improvement on my S9, which is a Batch 1 / 14TH/s as BitmainWarranty suggested.
