here is my feedback.
got the miner 3 days ago
to make it go online had to change the ip to .10 instead of .100 and put manually DNS server name
then tried different pools. nicehash, MPH, powermining. all same performance, 1 board not hashing fine.
changing frequency doesn't seem to do a big deal, with 900 one board stays dead all the time, with 800 dies after a while.
sent message to crypto drilling (shop I bought) and told me to freq 845 (which I can only put 850)
waiting for their technical team to reply..
this is my configuration

Hello Roberto_F
About the non active chips you have on the "ASIC Status" page.
Here is what i do when i have the same problem (Status black, yellow or red)
Go on the Settings page and just hit the "Save and Restart Miner" button.
Check after 2-3 mins on the "ASIC Status" page if its better. If not...hit that "Save and Restart Miner" button again.
Again, go check after 2-3 mins on the "ASIC Status" page if its better. If not, try this tome the "Save and Restart Machine" button.
Now wait 5mins and then check the "ASIC Status" page. If its's better...good, if not, pull the plug from the PSU and wait 10-15min.
Pull the plug back in and wait...
Again, check the "ASIC Status" page...if it's not better, repeate the steps above.
Sometime i need "only" 15 mins to make the chips all green...
One time it took my almost 1h...but it works.
My config is with 900MHz, mining on NH and the new Firmware.
Good luck and have fun.
EDIT: Sometimes some chips need more time to turn from black to green.
So if most chips on a card are green and just a few black, i just wait 2-3mins and then they turn green.
this is happening to me and i have a few in the red as well. Does this mean its time to clean the chips and install new thermal compound paste?
