Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
Ok, my S9 start working a bit better.
Most important thing was set fan manualy at 90%. After this at 650Mhz get 13TH+ but with quite a lot HW errors (0,0015%). After lower frequency to 625Mh HW drop to 0.0003% and speed stabilized at 13,1TH.
Strange thing is that miner need few restarts to hashig properly, sometimes 1 board hang at 3TH and dont want speed up.

those chips temps are wayyyy too high my friend. your running some dangerous numbers. they should never go much higher than 70 degrees c at the chip and each day it runs like that it loses a little more life until it finally dies. if posible i would try fixing this sooner rather than later. i dont want your hardware throwin out that magic smoke.
It would be nice for Bitmain to weigh in on this discussion. I know running the PCB past 70C can increase life-cycle maintenance or decrease effective life (I'm sure most of us have dealt with failed heatsink adhesive), but what are the chips comfortable running at? I've heard of chips running comfortably at 130C and some that don't like anything over 90C.
I run my S7s at 55C at the board. Anyone know what the likely chip temperatures are based on board temps?
