I finally got my 2 miners online via hosting.

Jupiter 1 = 172 Gh/s
Jupiter 2 = 12 Gh/s

(past hour)

kill me

hey we have 6 jupiters in the hosting at KNC and it looks very bad! but where could you get information how fast they´re running.... no Coins mined at all.... had smo on the phone, they couldn´t get us further information?!

pls share some informations

People on bitcointalk.org said they are using BeQuiet Silent Wings 140mm and Arctic Cooling Freezer i30/A30.

ARCTIC Freezer A30 already comes with MX-4 thermal compound, which is generally the best carbon compound you can get. The CFM of those 120mm heatsink fans are 74. They could be replaced, but that is generally a high CFM. The 140mm fans are 60 CFM, and likewise that is high CFM, especially at 15 dB level.

I think I might not replace the fans, but I am going to add a bunch of ram heatsinks on the components, including around the heatsink to cover the chip completely. I dont have my miner(s) yet, but i see people reporting that cores shutdown while others stay on. i am not sure what that is about. but i want to keep all the cores on and cool

I logged into the portal (portal.kncminer.com) with the info they emailed me this morning.   I had to call since I didn't get the info prior to calling.  The pool they configured the boxes to was incorrect or it appeared to be mining to KNC's address (1D5FhoiuLMJJ43BCMGidwvbKWfr71g1vH9)

I changed the info to my worker on BTCGuild.  After you hit save, the settings won't show up immediately.  The miner then goes into a "pending" state and comes back in a few minutes.  then refreshed and saw my new settings.   It appears they are not running the same method as the boxes they sent out.  When I change my pool settings things happen immediately on the jupiter I have at home.   Looks like KNC build some management portal which is really messing things up for everyone.

12 GH/s!  Seriously..  WTF.

Now friends, there was only one or two things that this gamble coulda done at
the end of September, and the first was the hash rate was ok, the chips were
on time and ok, the company was honest, and the mining machine just makes money
hand over fist while everyone else tries to play 'catch up', which wasn't very likely, and
we didn't expect it, and the other thing was the hash rate rose exponentially,
the chips were late or faulty, the company was crooks, customs delayed everything
and we all felt like we hadn't learned from BFL or Avalon, which is what we expected,
but when we got to the end of September there was a third possibility that we hadn't
even counted upon, and we was all sent canned messages saying that we are working
through the order queue based on payment date and not order number. As soon as
your order is produced and shipped you will receive a UPS tracking number via email.

The queue was the only thing that didn't change.   It was always payment date with the exception of the preorder queue (first 7 days after payments opened up).   The last category was 1-500 units which the queue started with (but u still had to pay within the first 7 days)

KnC should hire that guy with the husky voice that does movie trailers and make a video ad.

They have all the elements going for him to whisper, " An epic journey into the unknown, share the joy, weep at the deception, see the race against time, feel the suspense, marvel at their speed,  live the fear, see the dynamic explosions, heaven or hell...how will it all end?"

I'm dreading my box turning up now after reading all these last few pages today. Anything could happen.

They should open the miner up and connect the wires properly. they must have came loose.

Someone in the kncminer forum had a similar problem:

The unit at my home is hashing perfectly.   around 550 for a full 24 hours.

[minerpumpkin]

KnC is promising 550 GH/s, but we have to consider that Jupiter has an equatorial surface gravity of 2.528g (approx. 2.528 times the gravity we encounter on earth). Which means that we are bound to achieve approx. 217.563 GH/s. Stockholm, where the devices are supposedly being hosted, is located at a longitude of 59.35(N). That is 0.6594 the distance from the equator to the north pole. In order not to get into too much of a hassle with radians, etc. we may safely assume, that the average ground speed in Stockholm is about half of that at the equator (465.1 m/s), which gives us half the centrifugal force, halving our 217.563 effectively, resulting in 108.7815.

Bottom line: If your hosted Jupiter performs at about 108 GH/s, give or take, you are on the safe side!

Good to hear. Hope it stays that way, that's what we all expected after all ...the hashing perfectly part.

[regular]

We definitely need to keep track of performance as more chips go.  Perhaps the foundry process improves and there will be minor revisions to the chips as time goes on to reduce the HW errors and inconsistencies.

at the pool or just cgminer boasting?  (I don't really pay attention to what cgminer says)

tough to get 540 at the pool for any length of time

that rate is from BTCGuild,  it goes from 540 to 570 but looks to average around 550.

emailed Sam about the low hashing rate on hosted units asking him for a bit more detail and to be sure the issue is known. 

Hope this helps, some detail, they know about the issue, and they are working on it.

We have been aware of reports with underperforming Jupiter’s and we are working to fix it

Right now the engineers have a solution that is going through coding and then through testing.
It will then be sent out to all customers and applied automatically to all hosting customers,

This fix will improve the hashing speed, by placing more intelligence inside the FPGA and not using the mining software to spot bad routes through the chip, so any issues won’t have an effect on the mining performance the software will then be able to concentrate on mining and thus increase the performance

Im at a loss what could cause apparently all hosted units to exhibit this problem, whereas nearly none of the shipped units have this.
Datacenter only has to provide:
-  electricity (which could cause all kinds of trouble, but is unlikely to cause extreme low hashrates),
-  internet,  with nearly zero bandwidth, not something that should be difficult to achieve in Sweden, and the webinterfaces seem to work, so thats not likely it either
-  Cooling. That could be a real issue, but these reported hashrates are soo low, I could only believe that to be the cause if its like 40-50C in that datacenter. Im sure they would notice...?

Anyone else have theories? Do these hosted machines run any software that the non hosted machines do not run?

(posted before I read the post above me, but that doesnt shed much light on it either, or does it?)

Support started mentioning that the configuration of the hosted units were different than the shipped units and when I asked more questions they quickly stopped and said they don't want to give bad info.

I have a feeling the setup is different so they can manage all the units and through that routing something is messed up.   All we can do is wait.

Another data point:

I received my "day 1" Jupiter on Monday which had a heavily damaged box, slight dent in the case, three fans knocked loose but has been mining at around 500GHASH. However, not long after upgrading to 0.94 the hashrate dipped to around 400-450MHASH which might have been related to a DDOS against BTCguild since my Avalons also experienced a slight dip around the same time. I simply rebooted it via the web console and it has been running at 485-535GHASH for the last 12 hours in a 72F ambient room with the following internal temps:

ASIC slot #1: 51.5 ℃
ASIC slot #2: -
ASIC slot #3: 57.5 ℃
ASIC slot #4: 63.0 ℃
ASIC slot #5: 54.0 ℃
ASIC slot #6: -
