Disclaimer: I have nep not a tit.
I doubt they reinvented their shitty PCB for the tit though.

It might mean that cube has no 12VDC power.

If you unplug all the 12VDC and turn on the controller with the ribbon cables installed you may see just temp.
On a nep you WILL see the "ASIC" temp.

@Notthematrix, Searing or others:

I've got 4 neptune cubes that get power and show up in the GUI, but I can't seem to get them to fire up.  I've tweaked the die settings to no avail.  Any ideas to get them working or is there any value to them?

What does it mean ? why i have a cube without clock? Does it have effect on mining? can i correct it?

Thank you

the $69 buck comment as a raspberry pi science kit was to KNC's daughter board and the rest.....junk ....not very good junk either high  priced junk
their cost was probably $69 bucks not impressed with a controller board w/o even the expense of a case

as to the tech comment


point taken...but how many 300mh titans have you picked up for 567 usd (march 1st) or 2.3 btc ..complete and no dead dies
also with equip deductions for my orig titan rather then 10.1k for the miner ..whittled that down to 7.6k after those deductions

still knc miner orig purchase was a dumb buy at full price first in line

but hey I have other angles then just tech I do OK all things considered

To stupid to handle a miner sell it.
there will be happy people that CAB handele it btc a PI is about $39/$49 don´t know were you get ripped , a Raspberry pi for $69!!!

I guess my main point is that someone can tweak whatever improvements in the next bfgminer into some kinda way I can upgrade too.... that someday hopefully better
version of bfgminer if/when it comes out that would be great.....as to other tweaks to the source code....hey that is icing on the cake..don't beat yourself up on it

(it is knc junk by the by originally KNC  had a 3 month estimated warranty changed with the 1st month batch 1's not working well to 1 year but still you have to remember
 these units were only really 'designed' for 3 months per say....and they are not the most well built junk (i mean I'd settle for well built junk from knc has not even lived up to that)

I try to keep that in mind when dealing with the orig batch Titan's I have...my Titan has been going for 5 months now...i try not to make too much direct eye contact or dork with it much......i suspect it is plotting to 'brick itself' and any perceived slight.....and at any given moment

imho the Titans secretly long to return to inanimate objects as quickly as possible ...thus the somewhat futile race to stop them from the 'sweet release' of doorstop-ness...

frigging raspberry Pi $69 usd controller board science kit project included.....

(wtf was I thinking getting this crap?)

I've been looking into the source code and seeing what I could improve or make slightly better. Can't really do much improvement for these types of ASIC's, but it may be possible to pull off integrating a more stable control system. I'll see what I can do. Whether everyone here likes it or not, the KNC Titans are still the best Scrypt ASICs in terms of MH per Wattage (at least in Canada it is). Titans still suffer quite a bit from fast block efficiency, maybe something can help fix that issue without having to use a set difficulty.

Just out of curiosity.....if as I suspect....KNC has done its last firmware updates for Titan (and also imho neptune) .....is there a way to upgrade
when/if the next bfgminer miner beyond 5.1.0 comes along? Or does that depend on what bfgminer adds for enhancements vs how knc equip works?

Lastly I see that KNC posted the 'source' on github has anybody done anything interesting with that or as yet have not felt the need due to past
knc support

just asking last thing i programmed was in apple ][ basic...

Yes ...
diffrence is a lot of bug fixes!
and preformance enhancement.

1.06s is very stable.

Hmm, I get different numbers than that. The power cost in your area is a big factor though. Here's how I break it down, see if it makes sense.

For Neptune, average power is 1,950W, so recommended PSUs are 3 x 850W, or 2 x 1,200W. I prefer 2 PSUs, since it cuts down on components, cables, outlets, wiring, etc. For example, I can power 3 Neptune miners with 5 EVGA 1300W G2s, vs needing 8 850/860W PSUs.

On pricing, the EVGA 1300W Gold is currently $161.37, or $322.74 for 2. The Seasonic 860W Platinum is currently $169.99, or $509.97 for 3. A difference of $187.23.

Now, with 3 Cubes on 1 EVGA, or, 2 Cubes on 1 Seasonic, you're getting about the same load of 69-70%. That should be getting something like 90% efficiency on Gold and about 92% on Platinum using 220/240V. On 1,950W, that's 39W difference, x 24 hours, x 30 days = 28.08KW/h. I get between .11c and .12c per KW/h, lets say .115c on average, so that's $3.23 more per month for a Gold PSU, or $38.76 per year.

Divide the difference of $187.23 by $38.76 and it would take around 4 years 10 months for the Gold to use that much more in electricity.

Going with 2 x 1,000W EVGA Platinums would be 90% load, which I wouldn't want to do really...more heat, more component strain, etc. That would cost over $66 more for 2, plus the higher load would bring your efficiency down to around the same as the 1,300W Golds, with maybe 1% better on the Platinum. 1% would be about $19.38 a year in savings, or about 3 years 5 months to use $66 worth of electricity on Gold.

All that said, it's not a ton of money we're talking about here, so some people will just go for the better efficiency regardless of the extra cost. Especially if they are "Carbon terrified", as I like to call it. Or, as I mentioned above, if you pay a premium for electricity and that extra couple % would save you a lot more money. Still, even at 3x the electric cost on that first example, it would take you around 1 year 7 months to use that much more electricity.

Glad it helped. The list of changes is still on github: https://github.com/KnCMiner/images/blob/master/Neptune/Changelog but long story short, yes, I would upgrade. There were quite a few bugs fixed, CGMiner updates and some improvements. About the only bug I notice now is that the LCD is messed up. Sometimes the IP address will be off the screen, or in the MH/s spot, or the MH/s will be in the IP spot, lol.

Thanks to notthematrix and teslaman for their earlier posts about how to re-flash my Neptune controller.

I used a recovery SD to flash to RC6. Should I now upgrade to 1.06s?

What is the difference between RC6 and 1.06s? Is RC6 the initial version of the firmware (I seem to remember seeing RC6 when I first got my Neptune, before they came out with 1.00).

Yeah like a Pappy VanWinkle 23 or something !

i have days like that too … they pass …

best to post questions publicly here as there are lots of knowledgable people on this forum who can help.

as far as debugging procedures go, you want make sure that your Titan can talk to your pool, that bfgminer is running, that you have your pool config'd correctly (which it sounds like you have), and that the data in /config/advanced.conf looks correct (your advanced page) etc. after that, its anybody's guess ...

They call them fucking idiot trolls on this side of the pond ...

You truly are a buffoon aren't you?

No worries here.  It was proof enough for ARN and I received my refund.  If it helps somebody else, good deal.  I agree about the gamble, but the refund issue was purely their own doing by trying to get a datacenter up and going and not having all the financing in place.  As for wrong country, I love my country, but it's run by idiots and they are elected by idiots.  That's a different conversation best served up with some well aged bourbon.

Ill try later, can i write to you to aske other question ? Thank you very much again

lolll nothing work :@ my password dont work on putty arwwww

no special router config necessary other than what you do for your Dell box.

if you have putty installed, try ssh'ing into your Titan using the username pi and the password you set up

once you are ssh'd in, type


and then type 'P' to show your pool status.  If bfgminer sees your pool as dead,

type control-A control-D to detach from screen and get back to the shell. Then type


to see if your router can route your Titan to the outside world

So the problem is clearly my miner :S its weird nothing happen when i hit restart miner. Did you make something special with your routeur?
