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

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.

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.  Cool


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

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.

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

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.

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.

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  Angry  Sorry, I could not resist!

Ralf / trepex


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.  Cry

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.  Wink

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.

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)"

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


To see a company deliver on time (a couple of days late  anyways Cheesy ) 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

I can confirm that, I've just received an email from Anna saying "Our engineers are making some improvements and new update should be posted later on today."

When you consider the teething troubles now are a learning experience and this was 1st shot at this for them, so next time they'll be wiser and better....other companies have a mountain to climb to match KnC from now on...why would anyone take the risk with someone like BFL when you compare histories with KnC? There's no comparison at all.

It's not just the rigs that KnC have done miners a favour with, the whole industry now needs to change to stay in business which benefits us massively. No room for cowboys anymore is there? Smiley

Problem report sent to KnC support:

Hello,

my Saturn miner is running with about 7.5% HW errors (0.93). It looks like this is normal / known by KnC.

But my cgminer process also terminates itself from 2x per hour up every 3h. I did not observe any uptime
of cgminer much greater than 3h.

I observed (by pure chance) such a restart life:
Everything did look normal. A new status update in the bottom of cgminer every few seconds.
Suddenly there did show up error messages like

KnC: accepted by FPGA X works, but only Y submitted (where Y=0 or 1 only I think). X was always < 10.

I did not manage to make a screendump fast enough.
Those messages did show up at a rate of 10-20 (?) per second. SO really fast. After a few seconds the
screen session did terminate and the cgminer process was restarted.

Ralf / trepex

KnC answer (vie e-mail) with small comment from me:

Hello Ralph Ralf,

We are aware there have been problems with CGMiner in the latest firmware 0.93. These have been fixed and new firmware 0.94 will be released on our website later this afternoon. Please apply this as soon as it becomes available.

Regards,

Liam

At least they are pumping out the updates. It's the kind of thing that happens when you rush stuff our the door to appease the angry horde without a proper beta cycle.
