I finally got my 2 miners online via hosting.

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

(past hour)

kill me

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:

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

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.

--response

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

Sam

Thanks,
Sam

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: -

Sounds plausible. Even more when I read that the non hosted machines seem to run with very high cpu loads and they sometimes work faster with 3 instead of 4 asics. Problem might be in the beagleboard..

i guess it is about the cooling
i have my miner improved from 80ghs to about 500ghs as i put a fan on the top
it run faster if i use better and bigger fan

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.  

If you look into the strings in the firmware, there's the name for the unit depending on the number of ASICs :
0 ASICs: 0_The_Headless_Horseman
1 ASICs: Mercury
2 ASICs: Saturn
3 ASICs: 3_Cerberus
4 ASICs: Jupiter
5 ASICs: 5_Five_Headed_Monkey
6 ASICs: 6_Hosted_Max_Speed

The name of the 6 ASICs miner makes me think (pure speculation) that they actually host miners with 6 ASICs and, using a modified cgminer, they distribute the hashing power depending on what "miner" the customer bought initially. When you ask to get "your" miner out of the hosting, they just send you a miner with the correct number of ASICs (pure speculation again).

That would make sense : more uptime for the customers (no problem if just one miner goes down), less costs for KnC (less controller boards), easier to manage for KnC (just run a huge "cloud" mining farm and distribute the hashing power through software only, it's much more flexible).

It would also explain why they have a "private pool" which is actually their way to redistribute the earnings.

I could be all wrong... or totally right Smiley

Have i just killed the Jupiter!?!

Just setup a new miner. Fired it up and recognized that one front-fan didnt work.

I didnt care cause without the case airflow should be OK. I started to change the setting via the webinterface and then the miner suddenly shut down.

I checked everything and found that the front-fan wasnt working cause a blade was STUCK!

So i "unstuck" it and fired the miner up again but NOTHING happens...........  Undecided

Whats going on???
