Just an update for everyone who doesn't couldn't get all their asics up and running.

I ordered 3 jupiters from KNCminer and they arrived last friday.  And my cowoker ordered 1 jupiter. 

These are great products once you get them up and running, but boy was it a painful experience.
The issues I had with them are below.

1.  The fans on the heat sink falls off easily.  When You hear things rattling in the box, you have to open them up and put the fans on the heat sinks properly.  And they use torx screw drivers so that was a pain in the ass, luckily I had a torx set around the house.  I had to open all 3 jupiter boxes to put the fans back on at least 1 of the heat sinks on each of the units.

I had only 1 unit with all 4 asic boards running properly the others did not report any status on the status page.  After resetting the fans, I took a closer inspection.

2.  On 1 of the asic boards, the serial cable (not the power cable) CRUSHED one of the pins on the asic board.  I took the unit off line and straightened the pin on the board and then the ASIC came on.  I was pretty happy about taht.

3. Another asic board on another unit, the asic board's serial cable was defective or had some impedance issue.  I swapped the 2 cables (the ones that were the same length) and brought that asic online.  At this point all my asics were working properly.

However One of my coworkers who purchased an jupiter as well couldn't get his controller board to power on.  The asics were all powered though since he saw the fans were spinning.

4.  My coworker debugged on the on board pins and realized that there was no power going in to the controller.  So he took apart his unit and looked at the soldering on the power connector and realized it was faulty.  He touched up on the Power connector solder and the controller now came online.  the man spent a good 6 hours on this.

These were some of the issues that came up.  I hope this helps some of the people having similar problems.

Wow, that's unfortunate and I hope mine do not arrive in that condition.

Couple of things.

Did you contact KnCMiner with all of the above information?

Did your coworker just void his warranty by soldering the board?  Huh

 I got sick of debugging after a while and was considering an RMA, then I decided to look at the hardware instead of the software.  And that's how I ended up fixing them. 

My first email I told them about my problem and what I have already tried to fix, and they gave me some canned response about how to enable the cores, which I clearly told them I've tried it already.  So definatly no help.  After I fixed it I did tell them about how I fixed it.

My co worker likely did void his warranty but I doubt they'd know by looking at the board itself so I don't think there is nothing stopping him from sending the damn thing in if it was to ever break.

speaking of humitiy i'm in the Midwest (winter is coming) but what is the humidly you should set your bsmt dehumidifier at if you are running electronic equip like the miners in your unfinished bsmt? approx. temp prob will stay around 62 degrees F.

Data centers run with 45-55% humidity (optimal numbers). Personally, my garage/basement de-humidifier is set to 50%.

To be honest I think people who are hosting their units getting around 380ish gh/s definatly have problem with at least 1 of their asic boards not working for some reason or another.  Though I had a small sampling size of 4 jupiters.  Only 1 worked out of the box ( still needed firmware upgrade though), the other 2 were doing 380 with 3 / 4 asics status with temps up.

A trick in debugging btw is let it run for a while then feel up the heat sink, the heat sink that's not warm means that asic is NOT hashing.

My two hosted units are still under performing...   340 & 480.   

My one hosted unit still has "paid" status.  Tongue

ouch.   (mine are from "day 1") .  One initially hashed at 18Ghs


Well, I am just a lowly 39xx, but I now see that at least two orders from other people that were paid after me, got shipped today. I'll wait out tomorrow and then will give them an earful...

Note for those waiting for DHL to deliver your units in the U.S.

A signature is required.

If you want them to leave the package without you being there.

You must leave a note with your signature saying that you authorize them to leave Waybill # XXXXXXXX

and don't forget to sign it, otherwise you will be waiting another day for your item.

Anyone else seeing this kind of reoccurring drop in hashing, I suspect it's got something to do with cgminer restarts or the like? I have other miners running so the graph doesn't hit zero but the new KNC miner does completely go offline for long enough that the graph picks it up....

I see that kind of thing on Eligius when someone is trying to DDOS the pool.  It's been happening off and on quite a bit lately.

They are just rushing the assembly of these units without testing them at all.

They tested my unit for like a minute.  I saw it go up on my pool, it seems like they only check it to see if it's up and running, and then just sent it.  I guess for people with experience dealing with hardware it's actually advantageous to receive these early but for people with no experience dealing with hardware stuff at all it will be very painful.



Not really, if mine turns up fucked they get it back. I paid for a working machine, not an electronics class.
Wankers, sending thousands of pounds of kit out untested to that extreme level of physical fault ..for the lack of half an hour running it?

Probably that they have another 7+ days of production left.

he next difficulty is estimated to change by 34.72% to 360,699,846 on block #266,111. That should be 5 days 5 hours 59 mins 42 seconds from now.

Instead of them rushing out crap because you've got a couple of whining asses... it would be nicer if they could fix the problems and address QA and shipping issues. I know some of you are in this to make your money back this week, but for some of us, we would prefer our ASIC to last more than past the next difficulty change.

This reminds me of the pick two saying: price, quality, speed (time to receive product)

I don't think BFL every picked any, but I think KNC has great price, I'd just rather have quality than them tossing a bunch of half working shit in a box because avenger is crying.

All they need to do is run each one for an hour. Then they wouldn't ship crap. An hour is nothing, they could run it on their own account for all I care, if it means the rig I get works and isn't a box full of faulty boards.

From that last report it doesn't even look like they are visually inspecting them.

I'm with you, Quality control is everything...and all it takes is hiring an inspector and a little testing. Nothing to slow the process down significantly.

Next difficulty will be very close to 400M or perhaps a bit over it. Your estimate is way too low. This will be a jump of +50%.

Would ROFL except it made me sad.

 Cry

your theory seems to be true though..  my one board with the dead die runs significantly hotter than the rest and that is with it hashing at 75%

can't see anything with the eyes that stands out, and while it hashes at 75% not really worth it to keep shutting things down to fudge with it for now

maybe RMA it when KNC gets out of the woods

me too have a completely dead die but all my fans where in place (i've checked while unboxing).

this happens for the two jupiters I own. (so one bad asic slot ech jup)

the common thing is that both the "flaky" asics are marked with a #3 stickers.


edit1: i've asked to hno (OrSoC eng) on irc channel it there's a relation between number on sticker and quality and he said a "weak one", but he didn't say everything he knows imho (and I can understand him)


 

Any significance to the sticker numbers? All my Jupiter boards have a "1" and I've been running 525-550GH/s fairly consistently.

Oh, you cant blame Avenger for holding them to their confident promises that they made over and over. That is their mess completely. They seem to think that one rig displayed on 30th Sept. hashing over the spec is worthy of claiming ALL rigs are similar. A great many aren't close to spec. We didn't pay for a lucky dip. ALL rigs should meet the min stats.

If anything I said meant diddly squat to KNC, they would have been in full production over the weekend.

It seems all they are doing now is cutting corners upon cutting corners, anything to save some money. While their customers lose theirs. Unadulterated, ruthless greed.

As work day is now over in Sweden, earliest I am likely to see my unit is now Wednesday (and I very much doubt that). So since the 15th October, I will be down ~8BTC (currently $1,402) in lost mining revenue. I'll never see that back, thanks KNC.

Above all else we will be fair.
