Finally.  The good news is "only" 1200 mBTC lost.  I need a drink now.

To anyone suffering the red & green lights of death follow KNC flash instructions up thread plus:
a) make sure controller board ground screws are tight.
b) make sure the sd card is formatted FAT16 (not FAT32).

Not off topic I think if we're talking about sdcard formatting - but for android cellphone that kept disconnecting the sdcard this worked, told it needed FAT32.  On advice read in a forum I tried formatting on a linux machine tho I didn't use fdisk I used cfdisk.  ran cfdisk /dev/sdx, deleted the FAT32 partition, created a WIN95 FAT32 type 0C then after writing the partition to the sdcard and quitting, I ran mkfs.vfat /dev/sdx1.  Running mkfs.vfat made all the difference.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

when i run the asic on it's own it seems to be getting power??

also i cranked up the voltage the same as my other asic, 0.0374 and then i was getting about 50w per die for the 3 working ones, yet to try with all 4 working

edit: getting much hotter temps now, running up at 66c, drawing 170w at wall

edit: running 68c now


edit: cgminer is showing nice stats -


edit: running, on higher volatge, much more heat and 210w instead of 170w from wall, no reall hashrate increase, stopped after a minute or so.

So I got something.  Not sure if these matter or not but for those with similar issues.   I believe the SD card needs to be formatted FAT16 & my rig might have had a loose ground screw. 


Glad to hear!

now i have connected my other 4 boards I am back to having the same problem  Undecided originaly, the die 0 which had no power came on with power but the others in that asic were low, after a factory reset the other 3 die had power but the original didn't.

the asic in question is running on it's own PSU at the moment

whats causing this conflict? asic works fine on its own with 4 functional die, with the other 4 original boards also running, then 1 die on asic 2(upgrade board) won't power

more than one supply or a supply with multiple rails there might be a missing common ground problem on the dc supplies.

One thing that I would suggest is take an ohmmeter then label all the plugs and make a truth table finally check for continuity between all the grounds checking off the truth table so you know you didn't confuse anything.

I would imagine a supply with separate rails for the 12v supply on multiple 12v plugs should have a common ground between those as well as between the 12v and 5v but who knows maybe they depend on the motherboard to introduce a common point between the voltages.  The miner might not make the ground common in an effort to avoid ground loops - ground loops happening when grounds have more than a single common point.

Using two supplies I would think it could be necessary to join the grounds between the supplies and not count on the miner to make them common.

Asic2 has different volts from the others, this is an upgrade module, are these boards different from the original?

+0.0374V is the default voltage offset for the 8 VRM October boards.

-0.1121V is the default voltage offset for the 4 VRM October boards.

Any word on reopening 28nm sales again?  These excess bitcoin are burning a hole in my pocket.  Especially with BTC prices back up.  I'm done with preorders for now (I think), I just want more hashing power NOW!

I just unboxed my jupiter. I looked up what IP address my router gave to the box, but i can't go to that IP address from any browser. I tried revoking the DHCP lease so the miner would get a different IP, but I still can't access the control panel of the KNC miner.   I tried the "push the reset button 5 times, wait 5 seconds,push  5 times again" twice as well.

Does this mean I have to ask KNC for an RMA?

go back in this tread a few pages there is info on how to reflash the unit if needed.....compelling read...hope you don' t need the whole process to get it up

(others on here are more informative on this but its late here in usa so all I have is a point in the right direction ie reverse back on this thread see if you unit has those sysmptoms)

i start hash ghash.io

eligius continues with problems

Same problem here, ELIGIUS pool give´s my nov miners everytime an diff of 1024, also two or three times an hour
it is changed. And every time when this bs pool change the diff my miners deliver not accepted shares.

So that at of the day only 91% and less of the delivered shares are rewarded.


Ohh stop telling me about the worker like kjhsdfkjhasdjkf_Worker1, I know and use this.

Over the past few week´s, I made so many test. I figured out that for my miner is one special DiFF is the best,
so that all of my nov Jups deliver 710 to 715 Gh/s without any refected shares. Ok, a little handfull but this
doesn´t matter. =100% accepted.



Open here an pool: Open Pool Now - Ghash . io

each time you send a transaction don't forget to use a new address, each time you receive one also!

Well why the hell did you up it to 3.30 volt

I  tried on my jupiter slowly up my boards because i had a die 0 issue board.
Knc asked me to try up the volts

While i was upping the volts in mini steps 2.00 , 2.05 nothing changed
Then i tried 2.10 and guess what the whole miner went berserk
Constant ajax errors and constant page errors in the status pages
It scared the hell out of me, and btw if you look well you see its - x.xxxx volt towards 0.0000 and upwards
So this means you start with -0.1121 or something and you up the power by making it -0.1113 means you up the voltage on that die 0.0008 volts.
when you go over 0.0000 its clearly easier to see.
However even at -0.1221 at 2.1 volts mine was completely messed up
This is clearly not something for me or my controller board is a brick.

Also i have no clue how warm / hot these boards are allowed
This far i have not been able to get 1 single hash increase out of this, and it clearly is makes the miner go berserk.
Ofcourse i have no clue what i am doing with this
There is ofcourse no explaning what is the right thing todo or how to see signs of problems.
knc has a habit of not providing info about anything, so we already getting used to not getting any by now.

I am also wondering why some boards show using 40 Amps and give with 31 watts  at 33 c
And the other board shows 44 amps with 35 watts and is 53 c

again don't jump on me for this ..but are you aware of the past info a few pages back in this thread on reflashing your beaglebone seems some NOV units are arriving as bricks...
if this does not apply to your problem sorry all this is above my pay grade...all I have to contribute it the previous pages thread on reflashing

anyway hope it works out
