to @zigminer founder
thanks for new image and fan speed option.
as you said below, we wait the autorestart option for low hashrate and hashboard.

i wonder that will these machines able to run lyra2rev3 in near future or any other algo.

about overclock , maybe next version. i need more test .
about hashrate goes down , just config autorestart , if hashrate low , auto restart will slove this problem.

New Firmware 20181116 - Overclocking bye bye

How do i know that? Very easy...

I made a lot of tests about OC

Before my miner stopped working (Fan Check Problem - now solved with version 20181116), i was running Firmware 20180930.
Firmware 20189030 was the first version with a working overclocking.

----------------------------------------------
All Firmware before 20180930
@900MHz: ~6GH/s using ~1200W
@1000Mhz: ~6GH/s using ~1200W
You can set the MHz at 1000, it shows 100Mhz on the Mainpage of the miner BUT it does not work.

----------------------------------------------
Firmware 20180930
@900MHz: ~6,5GH/s using ~1200W
@1000Mhz: ~7,1GH/s using ~1400W (Chips ~3-4°C hotter)
Working OC, needing more power and getting a bit hotter...perfect.

----------------------------------------------
Firmware 20181116
@900MHz: ~6GH/s using less then 1200W
@1000Mhz: ~6GH/s using less then 1200W
You can set the MHz at 1000, it shows 100Mhz on the Mainpage of the miner BUT it does not work.

----------------------------------------------

So we are back to square one with the performance of the miner...

Don't get me wrong @Zigminer
I'm happy that you solved my problem with the Fan Check option.
But...yeah, the performance is gone cuz we can't overclock the miner with this firmware.

Edit:
And i have again the problem that at some point the hashrate goes down and i need to restart the miner so many times b4 it's back to normal.
