We are using s9, the advertised hash-rate for that batch of miner is 11.85th/s.
It looks like the reset issue in 7a is not solved. Undecided
Miner constantly restarting over and over again even after it ran through the config process. hw errors are low to non existent at all so im not really sure why the firmware is set to reboot the miner over and over again. its so bad that the pool i use shows my hashrate is only 400gh/s out of the reported 13.2th/s on the status page and thats because it spends almost as much time restarting than it does actually mining.
Using the latest v7a.
Any ideas Huh

after i go back to the stock firmware the miner runs at 11.7xxth/s all day non stop.

Fix Fan: Device does not provides control of fans,so the fans working with 100% rpm, all kinds of situation (if you don't have cooling room then you should choose this)
Auto Fan: Device provides control of the fans,so the fans behave according to the temperature of the environment (if you have cooling room system you should choose this)

A couple of Questions
with psu rated at 1600W what would be the best settings to ensure that all running smooth and avoid psu blow up?
should I limit frequency to 725? would it be ok to use 1650W as measured on S9?
