I am not sure this is the right place for this but this seems to be a catch all thread so here goes.
I have 2 late October Jupiters. One I was able to get to 550 with all cores running under 98.1 beta. The other has 2 cores on one board that will not work until 73C or 74C and as soon as they start the whole board shuts down (I assume thermal shutdown) so it only works at around 480.
I was living with that (not economically feasible to give up 480 hashes for 2 weeks to rma the thing just to maybe get another 60 or so).
Now the problem. I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start. The bone boots and I can tty into it. I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".
I tried changing firmware. Cgminer will run on 98 but not on anything after and on 98 I have all die 0s dead.
Anyone have any clues?

Trouble shooting wise. Make sure all the power cables are correctly attached. Do a hard reset on the device: HARD RESET
The miner is equipped with a hard reset button. This is located next to the power
input on the controller board. To perform a hard reset on the miner you must
press the button 5 times consecutively, wait 5 seconds, and then press the button a
further 5 times. Please note that the miner will not restart.
Also: From the KNC support page: https://www.kncminer.com/pages/troubleshootingUnderperforming Miner
If you have a miner that seems to be underperforming you need to follow the below instruction.
To verify if an ASIC board is broken or the performance drop is due to software issues please follow these steps:
1. Turn off and disconnect your PSU.
2. Open your miner case.
3. Unplug the flat ribben cable connecting one of the ASIC Boards (the circuit board that has the big fan on it) to the controller board.
4. Unplug the PCI-Express power cable from the ASIC board.
5. Ensure all other cables are connected properly.
6. Reconnect the PSU and power on the miner. Let the miner work for an hour to asses performance.
If the miner is now performing as expected you should install the latest firmware.
7. Turn off the power and disconnect the PSU, reconnect all the PCI-E and ribben cables.
8. Restart the miner and install the latest firmware.
Lastly, If you can isolate the bad board, then you can just return that bad board for an RMA and the miner can continue mining, you don't have to lose the entire miner and 480Gh/s just for one bad board. |

I don't really see why anybody would really lie about who they are here and bitcoin mining probably attracts a pretty techy set of people. I've been in distributed computing since I ran a large seti@home team back in the late 90s and the only reason I wasn't mining in 2010 was because I was doing folding@home after a career change into medicine from tech. I'm sure there's tons of people way more tech savvy than me here so it would surprise me more that there weren't more people like aerobatic around.
I will say that I'm still kicking myself for thinking that bitcoins was a silly idea back when I was throwing all my computing power at folding@home. Would have mined a ridiculous amount back then with my computers.
Join the club!    LOL yeah just running a fraction of what I've thrown into Distributed computing in the early days and holding it would have been a smart move. But no-one could predict, really the only way to have done something like that would be to have forgotten about the coins for a few years. Most speculators would have blown their load on the first 10% price hike. |

Looks good, but every hardware is different with respect to dud cores. Some is golden and some is scat.
ck, can you elaborate a little on the difference in behaviour & reporting between the 3.8.2 tuned and non-tuned on a KnC miner? I haven't run the latest tuned version but in earlier ones it would turn the cores on and off according to number of hw errors (off) and time (on) To see the status I'd run Update Asic Status on Bertmod and see what cores were turned on or off, these numbers would change over time obviously. With the non-tuning version of cgminer, the cores don't get turned on and off. With both versions of the software they report HW errors numerically and as a percentage. Is there any correlation between the HW numbers and the different methods that the tuning/non-tuning versions of cgminer use to handle cores? Or are HW errors irrelevant due to the way the KnC hardware reports them? Cheers! |

Sorry this is a little late but how many bad cores do you need before KNC will allow an RMA?
Was your ASIC completely dead before KNC would give you an RMA?
I have one ASIC with probably 15 bad cores which slows my hashrate...
Or just live with it?
>>>As soon as the first report good numbers I'll go for it.
>>>Currently running stable on 3.8.2 with my 5/192 bad cores board, so I don't want to mess with it now.
felix is it 15 bad cores or 5? You know that with the tuning cgminer it turns cores on and off to try and find a stable medium. What are your HW error %'s? I've given up on the firmwares that pump the voltage up (>0.97) and tune the cores, I'm sticking with 0.96 and the non tuning 3.8.2 cgminer and my HW errors are down from 4.5% to 1.3% and dropping. |

Heads-up for tomo BTW - incoming...
Also want to add, my ambient temps are 30C - 86F. so statements regarding VRMs needing heating and/or not liking cooling is NOT a fact covering ALL rigs/VRMs and even when they are hot(ter) they dont ALL fall back into line.... im sure ive mentioned this... As for 'wiggling' the heatsink aka 'cooling tower' - i think ill give that a miss. i personally dont want to hear 'warranty' is void due to negligence/abuse/possibly insane advice (though it might just work) Regarding your temps, what temps are you getting? I noticed my rig was starting to drop performance no matter what firmware I used, even going back to my faithful 0.96 firmware didn't seem to make much difference. (circa 530Gh/s av) However I had noticed that the ambient was getting pretty bloody cold here, so I moved it to a warmer location and performance jumped around 10Gh/s, then I reloaded 0.96 (always seems better for this rig, lower voltage, more stable) but wanted more realistic output from cgminer so loaded up ckolivas' latest 3.8.2 without tuning. And low and behold, the higher temps, the best firmware and more accurate cgminer and I'm back up to 550Gh/s avg over 24 hours, with spikes up to 600+Gh/s Thing is edgar, these machines aren't perfect, they are enthusiast level, makes sense really for the market they are in. And as such they need a bit of TLC to get the most out of them. Yes some will be broken and need RMA'ing as a last resort, but there is no hard and fast rule that works for each one, and I think that finally KnC have realised this too, the tuning suite sounds more like you will be able to tune each ASIC separately for voltage, hopefully speed and maybe some other things. This isn't going to mean that someone will give the "magic settings" that will work for everyone, if anything it means more work to find the best "tune" for your particular rig. Its a bit like overlcocking CPU's or GPU's no-one elses settings are quite right for your particular hardware. I mean, I guess, they could have set a generic right-for-everyone 400Gh/s firmware but I think they knew that their hardware had more potential, probably a bad move on their part shouting about the upper limit of the October batches, but it sold alot of miners I bet! I've been pretty happy with 530Gh/s but with difficulty increasing I'm looking to squeeze as much out of this puppy as I can, so today its remove the blue power cables and plug the Pcie's straight into the boards  This is an enthusiasts forum, and people are allowed to get enthusiastic, believe it or not Phoenix and the others in here have help loads of people get their machines working nicely. I for one think they are doing a great job and should continue. I salute their successes and apply what tweaks work for my rig, sometimes I even pass on things that have worked for me. Thats the nature of forums like this, no offence, but it doesn't seem like it suits your nature. I just wonder what you actually want from this forum? Can you spell it out? Maybe bullet point it or something so that you have a record of the things you want addressed. Can't promise anything mind but it might help us understand why you seem so angry.  |

Where is that screen capture from I've only ever seen it say November (and it still does on my screen) That's Cyper's handiwork, it doesn't say that on site... To be fair, my screen says "Jupiter November shipping - SOLD OUT" |
|
|

hum... Can't say if they are scam or not. Jan/Feb Delivery, right price range (not too cheep and not too expensive), put some effort in the side design and other things.
If it's in production now, they should be able to ship in December...
Hard to say
On the bandwagon ready for another free trip sushi? |

Calm down folks. I just posted it to let people know it happens even to developers, and have read what people suggested, but none of those fixed my particular issue. Every time I try one of those fixes things seem to just get a little worse so I'm afraid to touch it now...
I read something last night where someone had networking problems and they ran a script to reset the network card. I'll try and find it |

[2013-11-21 18:02:14] KnC: core 4-166 was disabled due to 10 HW errors in a row
On my upgrade board. Not sure how to handle.
Did you let it run for a while and heat up a little? Dude....cores enabling & disabling is totally normal.....relax Happens to about 5 of the 9 boards I have..... and some of those are faster than the others with all cores running.... I actually noticed that some of the miners with cores disabling have a lower error rate than those that keep all cores running too.. again... totally normal.... Even like this so rapidly?

It never stays at 340. I'm not panicking or anything, I'm just trying to get a feel of what I should be getting vs what I actually am, and to make sure I actually installed this thing right. How many modules do you have installed? What PSU? Which firmware are you on? How long have you left it? Mine settles down after a while Whats the GH/s at the pool? What I see with mine is a flurry of activity every now and then if I watch cgminer for a long time. Remember that 5 of those messages are cores being turned back on, and two being turned off. If you don't want to see them at all then you could try something like firmware 0.96 which doesn't turn the cores on and off. But the most important thing is what your output averages out to at the pool over 24-48 hours. |

As I have said before, I believe that the only possible real solution is distributed pooled mining like P2pool. I believe that some distributed pool will eventually emerge that will be good enough and attract enough users that it becomes the 'best' pool (however that is defined), and then the integrity of the bitcoin network will be safe for good.
In the short term, trying to pretend that some miners making a conscious choice to 'save' the network by choosing smaller pools arbitrarily is just self-delusional, contradictory, and will result in pools that are less responsive to the needs of miners.
If you really, really want to 'save' the network right now then design the perfect distributed pool. Otherwise, make what money you can until someone else does.
The problem with p2pool is that for most its barrier to entry technical level is too steep. I mean this is the instructions for setting it up in Windows: https://bitcointalk.org/index.php?topic=18313.msg712967#msg712967And this in Linux: https://bitcointalk.org/index.php?topic=62842.msg734371#msg734371Vs, Change one line in your miner to point to elgius or two to point to most other pools. I agree. That is just one of many challenges for P2pool as it now exists. If I have a crack at it will it work ok with my KNC miner? |

It actually fits in with the Bitcoin ethos really well, but man they need to make it easier to use. |

Again, please try to choose any other pool at isn't currently 24% of the network
ya, choose a pool that takes hours for each round.... not me! I'm not in this for charity.... I see you atop Eligius page........ good stuff....you sayin' you'd move when wizkid reaches 25%? Only a month ago, everyone was worried about a "51% attack", now it's 25%? What will it be next month? Judging from your previous posts you are mining 24/7 and not quitting anytime soon. Quite the opposite. You have your moneys ready to be spent on more miners. If this is the case it makes absolutely no difference whether you are using a large or a small pool, assuming their fees and uptime are the same. Really. No difference at all on the BTC earned. Are there people out there that DON't mine 24/7? What a waste if so... lol but...I disagree....I DO agree it SHOULD come out the same....but it doesn't. early on, I took two identical miners, one pointed at slush, one at eligius, for two days..... Eliguis payed out about 15% more overall during that time.... try it...you will see. Maybe it's the extra loot he offers?...some, but not all...... OR... just look up recent blocks,and do the math..... Yeah, slushie had larger payouts, but less frequent(obviously)... I didn't feel like loosing 15% a day anymore, so settled on Eligius... I'm actually a bit hesitant to try another.... anyone on ghash.io in here have about 1.25 Th/s I can compare to? To be fair I think it needs more than 48 hours to average out, different pools have different "luck" at different times, its only if you are mining in a really tiny pool that it takes too long to find anything. I had stable output on slush's for a long time, now I'm on bitminter trying to win a Jupiter, but just for this month, I'll try Elgius in December. |

Looks like Keith is getting involved in the official forums. That's brilliant to see.
Yes, it's very nice to see someone from KNC writing courteous and professional messages, addressing customer queries politely with well written and precise answers. But Keith is you right?  |

I can understand KnC playing it closer to their chest for this release after all the hype and subsequent trials and tribulations around the October roll out they probably want to just do it a different way this time. But what was cool about the first batch was that it felt like you were more part of it with the pics and videos of the production run, you got a real sense of moving forwards of being part of something cool.
Thats missing this time round, and it would be great to get it back, is there any plan to release information regarding build progress? Some updates as to what stage the rigs are at or even some pictures or vids would be really awesome.
Just a thought.
Yes fond memories of delirium induced photojournalism via the torture of sleep deprivation throughout the kidnapping. If I were going to the facility again I would certainly add more photos, but I have a few conferences to attend from next week right so I can't be there again. Marcus will be, but he won't be taking photos. I certainly have more I haven't posted from before as I didn't want to bomb the thread, but they are from that initial week... Posting pictures of the October launch might be counter productive on many fronts. Maybe you could make a photobucket album or flickr or something for posterity. My intent was more about providing some sort of info-spike for the masses related to the current (Nov) build out to recreate some of the enthusiasm we felt we shared with the KnC team around the Oct launch. Something like you did with the pics of the spare boards being packed. Totally I agree with you on that, but do you know how much trouble that got me in?! Of course not, but I can imagine, but personally I think it would have been worse if you hadn't, but thats just me. I think people here like info, even incremental info. It doesn't have to be pictures but they can help. Of course it needs to be vetted and agreed by Sam or Marcus or whoever, it may be worth asking. |
