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.

How did you revive them?

I have not seen anywhere clearly how can be done.

Can you please give some directions?

Thanks.

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.

Maximum operating temperature of the BMR46x series is 125 C.

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

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 ?


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

Ah.. Ok.. thanks.
So we need to cool them down below 70C to as far as possible... that's quite a task (if not impossible).... but still there is the OCP of 48A

Avenger, good to see you are still trolling this thread. I know you guaranteed many times that nobody would get a neptune before the end of Q2, but here we are again and KNC is shipping.

Get a life, move on from this thread.
