Hi to everybody, I've received 3 unit 2 days ago after more than 3 weeks ...... .
They start immediatly to work and after 12 hours first begin to have web interface problem, yestarday also the second, third it's ok.

https://ibb.co/miwfub

They mine correctly (I can see on slush that they are working) but I cannot do and/or check nothing from web interface, any help frome someone of you ?
Thank you

I saw the same thing, I found leaving the webui up and logged in will produce this problem, probably a problem with they way they are caching the web server on it, but, if you just don't leave the the web ui up 24/7, it seems to always work fine if you log into it every time and then log back out. Not a problem for me because mostly I monitor the pool page for my stats and only log to the miners occasionally.
There is no ssh access unless you flash your own load on it (tekcomm can show you how for donation), and the webui restart seems to do absolutely nothing.

Thank you, I'll try your solution.
Anyone tested the tekcomm new code to to sped up the ebit ?

I havn't tried his, but experimenting with other miners, it may be a bad idea to crank them up.
Those chips are probably most efficient at the 750PLL, you start using exponential more power as your crank it up to get near 13th/s and you get alot more hw errors on top of it, and more heat, and noise (from fans trying to dissipate the heat). They also become unstable and can render a board or the whole miner a brick at worst or have to be constantly rebooted/reset at best.
While they don't publish the chip power to hash rate chart for these particular chips, they all act more or less the same, there is a sweet spot of most efficient, a balance between hash rate, power use and heat, too low and you use the same power or more with less hash rate, too high and you use 2/3's more power to get 1/5 more hash rate.
If you know anything about chip manufacturing, of your end result mass produced chips , some will be much better/stable at higher freq than others from the same batch. Sometimes they pick the cream of the crop and make those run higher and market them as something different/better, in the case of asics it would be difficult and complicated for the HW and the SW to manage the 120 or so chips in these miners to all run at different freq/vcore, so they come up with a baseline where they should all work good at. Your start cranking up the freq/vcor (PLL) and some of the chips are likely not to take it. One on a board goes out, the whole board goes, not just that one. It is possible these are entirely stable at 13th/s, but at the very least you will use alot more power, it's not a linear relationship once you start cranking up the input juice

For example, this chart is for an older bitmain chip:
Freq   GH   Vcore    Power   J/GH
100   11.00    1.26     3.67    0.33
125   13.75    1.26    4.48    0.33
150   16.50    1.26    5.27    0.32
175   19.25    1.26    6.12    0.32
200   22.00    1.32   7.43    0.34
225   24.75    1.36   8.73    0.35
250   27.50    1.40   10.11    0.37
275   30.25    1.46   12.25    0.40
300   33.00    1.50   13.98    0.42

The best use for tekcomm's method is to secure your miner from stupid stuff like admin/admin id/passwd, and to get the ssh so you can mass admin them, and to be able to remotely reboot them.
