Yeah, I've flashed 2.0 on 3 different sd cards to no avail.

Older .img's didn't help.

I'm guessing that the i2c device is the kernel interface to the fpga on the controller board, via which commands are issued by the bfgminer titan driver to the hardware.

Without looking at the code I can't tell you more about this error. Does your uSD have a fresh install of 2.0 on it ?

If not, I'd recommend doing that then watch the console while it boots again.

Make sure you always ssh into your titan and do a


before power cycling it to avoid filesystem damage.

Good Call.

I tried that and everything booted for the most part until (paraphrasing)

[Warn] Kernel Lacks cgroups or memory controller not available, not starting cgroups (warning)

Error opening dev/input/event ......

and then more things succeeded in booting until finally I got one error which repeated in perpetuity:

asic 1-6 die 1-4 " "

Error: Could not open file dev/i2c-2 or dev/i2c/2 no such file or directory.

It continues saying that until it reboots. 

Anybody know what that means?

Well this is a long shot but you might try plugging a monitor into the rpi hdmi port, reboot and watch for any odd error messages as the system comes up.

According to KNC plugging things into the USB ports can damage the controller but the hdmi port is functional.

Pools are live and I'm about out of ideas. That purple light doesn't seem to be coming back.

Has anybody noticed the flat ribbon cables have letters engraved on them? And they're different for me.

E E Q A F

I wonder what that means, it has to be something otherwise the manufacturer wouldn't take the time to etch it. Probably not important.


Anyways, has anybody had success getting Titans to run on anything other than the KNC issued controller?

I'd recommend turning on debug logging on bfgminer but the last time I tried that on a Titan the whole machine crapped out …

You've checked bfgminer to make sure your pools aren't dead of course ?

Unfortunately bfgminer runs at 0 mh/s with none of the cubes recognized.
Sometimes it shows every slot as OFF othertimes the entire cube on/off interface doesn't show up.


It used to detect all of the cubes upon start up and then the pi screen would display info. Now I get one lone green light and nothing happens.


The only things I can imagine is the controller is damaged or the cords are damaged or it's a software issue.

I'd really enjoy a 'detect hardware' button on the KnCMiner interface.  

Does anybody have a configuration backup that is recognizing cubes? I don't know what that file stores exactly.

Is bfgminer running ? I think their webapp makes rpc calls to bfgminer to get data on the cubes.

I'm having a problem with my Titan that I can't resolve.

After a long period of successful hashing I unplugged the cords and moved my cubes.

After re-assembling everything no cubes are recognized. I can see the knc web interface but no cubes and a blank pi screen.

Yes the cords are seated properly on all pins. I'm running 2.0 but have tried several revisions on different sd cards.


Has anybody had this happen (No Cubes being found) and if so how did you solve it?

Hello, I have this problem with one of the cubes, and have touched the voltage if the module responds and nothing, still 000 ..... any ideas please or help.

Really?  I've been wondering just what my neptune consumes.  Since it's on 240v, I don't have a kill-a-watt meter.  I know the gui shows 4TH @ 1650w (6 cubes) but who knows how much is lost from other stuff even if using plat psu.

My SP20s get just under .5w/gh when I use the plat psu and underclock to 1150-1200gh.

people anyone have best settings for undersvolting? for neptune consume less watts

screw the trolls i just want to know who the f*ck is the girl in your avatar gif!

knc ended as fuckin scammers.
such a shame

here here: http://kncclassaction.com - you are affected somehow or just curious?

has someone the link for the KNC Lawsuit?

Retro is right, this thread has been filled with loudmouthed fuckwits since 2012.

the ones who repeat themselves and wear us down with gibberish are the worst offenders.

but it really is best to leave them to it - you'll only give yourself an aneurism trying to use logic among the 'special'

(also, 'they' are the ones who make the most noise when the self-respecting among us try to do the right thing)

adios, snitches!!

Unforetunitly that 'gates & Rockefeller schooling' your on about put together in 1903 is also been used in Europe and most so called 'developed' countries (replace developed with manipulated) and schooling is about programming children into not thinking and being creative and telling them do things one way and not another. Not to answer back and to accept what 'Mr' or 'Mrs' says! To wear a uniform and lose your individualism! Some even go onto further manipulation and join the army etc for some hard core programming and truly get their heads fucked over! All the scams like bfl are run by x military people exclusively lol. If you know anyone in the military you KNOW it changed them as a person. Its called social engineering, and its been going on for at least 2000-3000 years in its current form, if not longer!

I never let schooling get in the way of my education! - mark twain

The sad thing is the human race as been around for at least 500,000- 2 million years and we have been in a state of amnesia for 12000-13000 years due to an event that happened then that were not being told about. The ice age matches up with then but I believe there is more to it than just that. A few people since then, living in a tribal manner (we were not so tribal before and communicated worldwide which is obviously apparent by megaliths all over the world. Every country has pyramids, same philosopies (flower of life etc etc) so its obvious to anyone with 2 braincells we are being lied to about our history! Thats fucking obvious! But since then a few tribes rises to the top and power corrupts, absolute power corrupts absolutely!

Now we have the manipulators of China, the manipulators of Russia, the manipulators of the west (USA, Europe) working together for their own crooked needs. Its like multiple gangs working together! It may work for so long,but they fuck each other over in the end! Then only problem with that is this is the global 'alliance' and the people are under a global attack, but most people have their heads in the sand, reading and watching the properganda stations/papers and even worse, most people are blissfully unaware how much they oppress then oppressed for the oppressors :-( we do it all to ourselves!)

So easy manipulate the world!

Completely agree with this, notthematrix obviously has issues with comprehension given the lack of understanding with respect to the real issues..

American schooling I would guess

Fuck's sake, you are such a dick!

Nobody here is complaining about KnC because of the hardware needing 'fine tuning', as most people who bought from them are, contrary to your ignorant arrogance, more than capable of understanding how to set up ASIC miners.

They are complaining about KnC having lied through their fucking teeth about when they would have units ready and to what performance level.

Simply repeating how you consider everybody other than you to be too stupid and, therefore, prone to being 'frustrated' at KnC, is merely showing that you are either incredibly dim about the facts of the matter or you are actually ignoring the facts so you can keep apologia-shilling for KnC.

Either way, fuck off with your condescending attitude. The only person you are impressing with it is yourself.
