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.

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

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?  

 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.

This sucks.  Completely unacceptable on a >$7k USD device.

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.

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.

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?
Reputation  in ashes. That last list of stuff physically wrong was appauling. No excuse at all for that.

This is why you pay for hosting thru me, I give each box my loving attention/end of a stick till they work

My order is 4114 and apparently it was picked up today. If that means anything to anyone

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

[jelin1984]

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.
