In response to my asking about SSH and back-up pools (5-day old reply):

We understand your point of view and appreciate you shared your ideas with us.

Due to security reasons, the ssh remote access is only available for shipped devices. For hosted devices we offer web portal where you will be able to configure some changes.

At this time there is no option to set back-up pools but we might consider it in the new versions of web portal. However, there is a possibility to switch the pools manually.

update

jupiter received with v.0.91, upgraded to 0.93 => lots of cgminer restarts
downgrade to v0.91+rebootfix => runs stable, more hw errors, 20% lower effective hashrate
upgrade to 0.92+rebootfix => runs stable, 30% hw errors , 500-/+ effective hashrate avg

btw: after flashing downgrade it was not responding after reboot, had to power it off and on again, then everything was fine again

DID ANYONE RECEIVE KNC UNITS TODAY? AND IF SO, ORDER #/PAY DATE PLEASE??

trying to gauge more or less where knc is at as far as shipping queue/order #/pay date?? thanks.

Yes, sir
Proud day2 owner reports: order received this morning and is meanwhile up&running.
The whole scene from UPS ringing the bell until now still feels like a dream...hopefully it is real!  

order number was <300, paydate early june,
based on pre-preorder from may

0.91 firmware, flashed to 0.93
cgminer restarts quite a lot, but hashrate is 500+ avg

Packet damaged from the outside, inside is fine.
One fan was loose, clipping it back on was easy (make sure you have a torx screw-driver present to be able to open the miner's case!!!)

btw:
had trouble with the config - wanted to add to /config/cgminer.conf another pool, but after restart cgminer complaint about no pool;
double-checked the JSON everything was fine.
So I removed the config completely and restarted cgminer. Then connected to it via ssh/screen and put in another pool through cgminer directly and wrote it to file on disk.
I hope it's still present after a reboot, not tested yet.

It`s a shame for KNC.... people get their unit a week earlier than others will receive for same confirmed production day (day 2 should be shipping). It seems "one KNC-day" is nearly a week in rest of the world.

[Nemo1024]

Well, at least it's not "two weeks"(tm) equalling 2 years.

well why wont you go over there and make miners for them and see how long it takes you. Thies things are not all automated on the putting together process. It takes time to make/pack them. Damn hold your horses.

Indeed!

Does someone have an IR camera to see the Picture of Jupiter hashing with temperature scale on different Components. I'm just curious if attaching small ramsinks on different Components would avoid an eventual burnout?
If all Components is down below 70 degrees C then i don't see a reason but above that lowering the temps would be useful.

My "rule" is simple. Touching a Component for about 2-3 seconds and you have to remove your finger unless you get burnt! Then i consider the passive Components to be a tad to warm to work 24/7/365.

someone on #kncminer irc channel said that the DC/DC converter reach a temp between 70-75° Celsius, and in fact he puts heat-sinks on all converters

Looks like the knc guy is packaging the first time in his life. No wonder now

Yeah putting the heatsinks on and maybe 4 screws for each board is too really time consuming.

For those with miners running i've started a thread to get some consolidate #'s on hash rate / error % on KnC forums.

http://forum.kncminer.com/forum/main-category/hardware/5563-hw-error

It would be better to make a topic here, KnCMiner forum is unstable. I can't even register. Here are mine:

    Miner Type: Jupiter
    CGMiner Hash Rate (average): 495 Gh/s
    CGMiner HW Error %: 17.2%
    Firmware Version: 0.93
    Uptime: 16 Hours
    Case: On


CGMiner crashes once in an hour or two. At the pool the speed is only 450.80 GH/s, with 95.37% accepted shares.
I played with some extra ventilation not really helped the performance.

[Vyper]

Ok thanks for Picture.. Then they are safe actually. I'm more curious about the capacitors around it.

where can you buy those small heatsinks?

[Puppet]

You should be able to buy them anywhere, local electronics shop or ebay. Something like this:
http://www.ebay.com/itm/IC-Alu-Kuhlkorper-Kuhl-Rippen-SMD-Heatsink-kuhler-Aluminium-Cooling-Aluminum-/320966208212?pt=Bauteile&var=510076969589&hash=item4abb13aad4

That said, unless someone provides a spec sheet stating otherwise, 75C is probably completely safe. VRM are typically specced to run at 120C or so.

refer you to here

http://forum.kncminer.com/forum/off-topic/miners-cafe/5386-shipping-log

Thread titled "Shipping Log". First post asks "If you would please post your order number and status (if shipped/hosted)."

And then people go on to post a bunch of "Paid" status orders... Come the fuck on.

People don't read. I expected that, so I am only going to post the last non-Paid status I see. As far as I know sbfree has the latest at June 18th paid. It's completely non-official, so it's whatever info I can grab will get put up there. Btw, did you all notice that their front page has changed (kncminer.com) and it says if you order today you're miner will ship in Nov (no date specified)? Not sure if that means Nov 15th batch is filled and they are going to keep building miners or that Nov will be late. Let's hope the former.

Hello,

I'd expect they have better things to do than adding for certain customers additional pools, etc now.
They said, in the beginning there will be the KnC-pool available, only as far as I can remember.
As soon as the management interface is up&running you can do what ever you want.
I'd hope they will not modify the config file via ssh for each and every hosting customer asking for it as it would delay startup even further.

I can fully understand if KnC can't configure backup pools before they have solved all the other problems with
the hosting, BUT:

- I have not heard anything about the KnC pool yet. After all the current problems (like webinterface having no option
  for a backup pool) I do not have trust in a KnC pool at the moment.
- From another call with KnC I still assume that no one will get ssh access to the hosted miner. In combination with the
  webinterface not offering the config of a backup pool, this is something that KnC must do manually. Sorry!
  The hosting is overpriced for a normal hosting and I assume one reason is that KnC must do additional tasks normally
  not covered in a normal hosting:
  Doing software / firmware updates.
  Configuration of "normal" mining features via SSH as long as the customer available web interface does not allow this.
  Replacing units that caught fire / did explode    Sorry, I could not resist!

what a bummer. we´ve choosen knc hosting since it was promised hashing "within hours" after production. we end up being behind even the remotest places, while our brandnew gear is resting....  in stockholm.  

4 btc compensation is a nice gesture, but...

"within hours" would be at least tuesday, october 2nd which is a week ago. so the loss is more like 10 btc per jupiter.

on the other hand, what is more important, that knc did actually deliver. no scam, no bfl style drama, but genuine professionals. all the nay sayers, all the haters were wrong. they achieved something big.

the machine looks good. hosting had a bad start. maybe they will come up with another little gift to calm hosting customers.  

[timmmers]

I'd guess that they found that they can't build them as fast as they thought so they amended the Nov date on the site. Fair enough, best to be honest. Doesn't bode too well for Oct 15th if that's the case though.

FYI: According to Emilia from Knc customer support "Day 1 hosting should be going online today. Login details will be provide later this afternoon."

[-Redacted-]

I can't seem to get the customer support people to understand that the worker name for my multiple orders isn't supposed to be entered verbatim.  Explains why there was no hit on my account during testing....

My machine arrived with the worker name set to    "rsbriggs_XX      (replace XX - I have multiple orders)"

[Menig]

FYI: According to Emilia from Knc customer support "Day 1 hosting should be going online today. Login details will be provide later this afternoon."

also there comes a new firmware this afternoon (information from calling with knc-support)

[YipYip]

KnC ....u guys are amaze me !!!


To see a company deliver on time (a couple of days late  anyways ) compared to the total scam/cluster fuck that is CONMASTERS INC @ BFL & then their prodigy love child AVA ( I FUCK U WHITE DOGS) LON

Even offereing compensation for the slight delay on the hosted units like W...T...F..

Josh read this monkey boy .....

KnC thanks you for deliverying us from the evil that if BFl & thier biatch AVALON

You guys are going to totally own crypto if u keep this up like white on rice

AWESOME
