I just got my fresh new rpi-b
Downloaded and installed the latest 0.2.5.pr1 on the 16 Gb superfast SD and all seems to work this far
When i used the rpi plain with only the psu which came with it it powered down when unplug the mini connector
So i took my little 10 port usb hub from the shelf with its 5 amp psu and the minute i connect the hub the rpi powers up on the normal usb 2.0 port.
Looks like the psu which came with it is now overkill or am i wrong and does it still need its own power
I have 8 devices which probably will be connected constant and maybe sometimes the usb wireless keyboard when it fails.
As far as i know the only one pulling some power will be the usb wifi-n dongle.
The other devices should not pull any power from the hub since they have their own psu.

Just for info the kncminer neptunes have an estimated delivery at Quarter 2 or 3 -2014
That is in my idea still march, april, may, august i never seen them post earlier

I do not have them very long but i see them showing those each day, after reboot all seem ok.
but during a day they slowly change all into the x ....
When i reboot them they are back to o, the nasty part is they are only a few days in my posession.
Even changed the psu from 850w corsair to nzxt 1000w and my 1350w one.
Seems to keep coming back, not sure if the fix on the fan will help will see that tommorow.
Crossing fingers that will do the trick

I have 2 s1 chirping like a small jumbo jet in the garage running.
All seems fine however every now and then the boxes show in the status all X on every spot where was a O
They was doing around 175 Gh after alot of threads about these miners, i decided to change the fan by removing the blue wire from the connector. which made the fan do its max speed. Ofcourse this results in a massive drop in temp.
Before the change the box was doing 46 C after the fix the temp dropped to 29 C running at the same 350 Mhz

Since it ran so cool i began slowly upping the speeds from 350 to 375 Mhz which did give a pretty nice boost in Gh.
The temp of both boxes stays between 30 to 31 C.
Because i saw all seemed to be fine i upped them both to 387 Mhz but one began giving more errors and began running slower so i changed it back after 10 minutes to 375 Mhz
The one doing 387 Mhz seems todo fine at that speed, when i up it to 393 i see it hash slower and giving more errors so after 5 minutes changed it back to 387 Mhz.

But my concern is still why did it show all the XXX on the asics while it seemed it was hashing ok.
Have to wait what happens now that i changed the fan to run full speed constant.

   

The 2 boxes are running for 2 hours at 387 Mhz and result is


             Gh. avg  Accepted       HW   utility  discarded     localwork       wu      Temp

Box1       196        24,941       3,102     175         506      455,826     2,801      30, 31

Box2       198        31,570            58     173         630      584,426     2,782      31, 31


Anyone know what the red led means which starts burning after several hours mining ?

Sorry guys for the late response

Had a very busy work period and got not much time to play with the miners not look at the tweaks of them

Have added the various options and started slowly test some of them

You guys was ofcourse right with the either the freq file not being correct or that the cooling was

It was the cooling the minute i took the blue wire from the connector they started blowing like an idiot

Which made a instant cooldown from 45 C to 29 C

The 387.5 was giving me a instant boost from 175 Gh to almost 195 Gh so i let the machine run with it.
But its somewhat early to tell the initial results are nice

However when i changed the values to the 393 settings the miner started to run slower. And the hw value goes up quick.
The same applies to the 400 setting, again i tested only shortly.
But in a few minutes both settings result in more hw errors and slower hash.

Before someone says its your psu .... i am sure its a very good one, it has feeded 3 x 7970 @ 1100 Mhz at litecoin mining with ease.
This NZXT hale 90 - 80+ Gold - 1000 watt, is not even start its fan to cool because its cold as ice.
(added test connected my enermax 1350 watt and same results)
 
Ofcourse the winter temps here to be near freezing and at some moments below -2 C help as well

[LAZY MODE] ON
How can i get the stats of the antminers onto a monitoring program like bamt had or something similar
And can scp be installed on these, so i can winscp into them from work as well
[LAZY MODE] OFF

Well i see the miner doing avg 175 Gh
So i thought why does it go so slow
Read the whole thing about changing the file in the miner
When i looked at that given file i see that it already has the numbers given
Still the boxes do not go faster then around 175 Gh on average
Not even close to 190 at all, anyone has a clue why they run so slow ?!?!?
Both boxes do run about 45 to 48 c with the fans doing 1800 rpm

Well i received mine and i am stunned how easy they are to setup and work perfect
No hassle just follow the easy todo setup guide
As usual wifi is slow

Yep I have the same problem the driver for the atmel is not working for me either on the boards.

Pff it costed me another 2 days to get all the boards running again ... i constant had one not wanting to hash no matter what setting.
But i am wondering why they run without an issue if they are direct connected to the pc
And more a miracle then they actually run at 48:2:950 ?!?!?
But as soon as they are pluggen in whatever hub or when the cable gets longer the hell starts

Grrr anyone know how to destroy the zadig crap out of windows install
Gawd i hate zadig so much it is easy to install but a nightmare to get it out of your system
Its almost a virus ..... did i allready made clear i hate it

http://i447.photobucket.com/albums/qq197/ubronan/drbboard.png

this driver was installed after i removed every and all usb installed drivers

sadly bfgminer does not see my boards
driver is libusbx from windows

Hi i have the same issues with the boards and have them running with cgminer controlled by cgwatcher
The setting i use is 49:2:850 with cgminer 3.10
However weird is that the older 3.9 version does allow a bit faster clocking 50:2:850 but you need to pull and push back the usb plug several times to get the board running without the unresposive asic messages.
It happens often that the miner crashes and you need to monitor several times to check if the boards do not pump out the endless unresponsive asic messages. If it does you are screwed again and need to start messing with the usb plugs to get it running again
this far i have not been able to get them to run faster because either the screen is full of unresponsive asic messages or cgminer crashes instant.
settings at 48:2:950 seems to be impossible to run

Luke-jr already a big thanks.
It would be awesome to have them running with multiminer controlling and monitoring it with bfgminer

Never mind the forum opened just now

Just made a profit calculation based with current difficulty 1,418,481,395.00
The 7 boards do around 110 Gh, they pull including 4 cooling fans and the usb hub and htpc (3 core amd) 270 watts
Electra price in dollars 0.37 Kw/h
Resulting in :

Coins per 24h at these conditions    0.0390 BTC
Power cost per 24h    2.40 USD
Revenue per day    31.12 USD
Less power costs    28.72 USD
System efficiency    407.41 MH/s/W

Hardware break even    93 days
Net profit first time frame    -44.75 USD

but sadly only 1 day left till next diff 1.8 billion +

Hi
Can not open drillbit forum and would like to know what should been done with the dead board
Tried everything to get it back alive but it does not react at all

Well i made a 510 euro withdrawal through sepa at 2013/11/02
It took them almost 2 weeks to send it out so i see it at 2013/11/19
Yesterday  2014/01/06 i saw that i got 442 euro on my bank so along the way it costed me 68 euro.
So a couple of days is an absolute fairytail, when you withdraw funds from gox.
But in anyway you do it its gonna cost you, i wanted to withdraw from btc-e to find they have a minimum sepa costs of 100 and up to 500 euro.
Bitstamp is a mess i registered fully and 3 weeks later i was all of a sudden no longer registered when i asked how this is possible they simply state they lost my documents.....
I have read many horror stories about them from people not being able to withdraw anything from them, so decided not to use them ever again after the so called lost documents.
The question is how trustworthy are the exchanges and how much in time is really needed to get funds towards your bank.
Because i saw others can do them fairly fast
To be honest i am actually thinking of changing bank because of the info these exchanges got from me and i am not sure if they really should be trusted with all that info.

Well its 6 januari and i am still waiting for news when my 8 x drillbit boards will be repaired.

Difficulty went up again and i have not mined a single bit yet.

Sorry people but its kinda easy to shutdown the miner without blowing things up

SSH into your box and then after login you type on the prompt

shutdown -H -P now and see how the machine stops running instant, this will protect it from running full power when turning it off

And yes do never turn on a electrical device instant after you turned it off.
Its a rule to give the components time to unload the power before powering it up again in most cases 15 seconds should do.
Since i close the miner in the proper way i do not believe blowups will happen since you have some time between shutting it down in the control panel and then goto the device to shutdown the psu. I my case thats about 2 minutes.

I had suddenly a die 0 problem and one of the asics was starting to turn off more and more cores on a die.
I had some back and forth mailing between knc and me, now they asked me to make a rma.
Just followed the steps and send the failing boards as they requested.
The next day knc reported to have fixed the issues and send them instant back to me
So in very short time the boards are back and hashing away.

KNC has prefectly solved this and fast.

So i am glad i did ask them for help, and instant did the RMA.

People saying it will take long ... NO ITS NOT it was lightning fast

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

nope nothing to track the code says not trackable or is not a proper code on other track sites:

This is showed by the aussie mail link:

Product not trackable

What does 'Product not trackable' mean?
