I hope the auto tune will fix the problem...because actually its nearly impossible to go over 49 TH/S in the very best case without overheating ( 45 TH/S for most of machines )
Another problem, the dev fee....
I have 1 T17 producing 49.48Th/s on miner control panel but on slushpool i have only 44.80Th/s ... its 10% of dev fee...
another exemple :
46.15Th/s on miner control panel and...41.64Th/s on slushpool... so less than original firmware !
I checked other machine with original firmware, and the the value are both same in miner config panel and on slushpool.
The dev fee does not affect hashrate. Look at the scoring hashrate on slushpool unless you looked at it for the few minutes it was switched it would be reporting the same as your web panel. T17 OC potential is limited without cold air but their underclock potential is fairly good!
If you are overheating try to play with your voltage levels and frequency levels. You can also undervolt your T17 and get more w/th.
Great looking forward to it. Hope to see some work on s17E models as well.

We plan on getting to them eventually that and the + model.
