I have removed the aluminum plate, so now I can see the Ericsson VRM's..... this is bad: they are the BMR4641002 (max 40A) instead of the BMR4641008 (max 50A). Angry

...... no OC possible !

The 1002 has a OverCurrentProtection of 48A and looking to my Advanced-page: nearly all the VRMs are already around 46-47A (and this is KnC's default setting).
They should have used the 1008 instead, which has 50A and an OCP of 62A.

40A @ 60C
We run em @ ~80C so derate to around 32A
(90C detate to 25A)
per the documentation

http://archive.ericsson.net/service/internet/picov/get?DocNo=28701-EN/LZT146435&Lang=EN&HighestFree=Y

Need to average in mind between first 2 graps on page 11 for 0.78V

YMMV

Elenelen, when you get a chance could you please read the numbers on the two black 8 pin packages near the side of the board and post them here ?

in my experience you either need more heat or less heat. If it's more heat, stop the fan is the easist way to create more to see if they kick back in. I have no idea if a nep box can be opened? You can also play with the Die voltage and increase the Die next to the none functional ones, creating more heat and igniting the dead ones.

did and the same hash max 300 gh / s can, t acess to advanced Sad

Did you try Ctrl-F5 (reload page from scratch)

Did you try each cube individually?
Perhaps one cube is hosed and spoiling the party.

Subdivide and conquor.

YMMV

do not quite understand, I turn on the same box ?

Neptune 1/5 2/5 3/5 connected to PSU 1
Neptune 4/5 5/5 + controller board connected to PSU 2

Start PSU 1 first, then start PSU 2.

I assumed this video would be helpful for someone.

j have 2 x 1250 W gold seasonic

26 my temp all asci

they should be sufficient. Start the one without the controller board first. Let them run for 30 minutes, they'll level out.

You should try a different pool if the problem persists.
