Have you installed the Bertmod firmware overlay yet? It shows more detailed information to let you better see what issues are afflicting your miner. It may be that some of your dies are off due to temp issues.
http://tadn.eu/bertmod/bertmod_0_3_for_knc_0_98.bin

Install it like a firmware upgrade via the gui, but don't restart the miner. Just go back to the stats page and refresh it. It'll then show you detailed information on each die. You could also try updating to the 0.98.1 firmware if you find that the DC/DC 0 is off on your boards.

Has anyone encountered the following problem:

Jupiter hashing away happily on 0.98 getting a very stable 560GH/s at the pool with case on and all fans on (i.e. as it was designed - temps stable between 60-70)

Then suddenly, after 6 days i found it had stopped hashing (luckily i caught it after two hours only).

I rebooted via the web portal

No other changes at all.

Now hashing at ~515GH/s after 24 hours, everything else exactly unchanged.

Very strange. Any ideas guys? how can i get back to where i was in terms of hashrate?

Tip on offer for a fix

EDIT: I forgot to add that after 24 hours I did a full power cycle i.e. switched off at the PSU for 5 mins then switched back on, then in the web portal i rebooted it just for good measure. Still at 515GH/s at the pool after another 10 hours....

Just run enablecores, and reboot
I suggest using 0.98.1, or 09.98.1 beta

[wasubii]

enablecores before bertmod or bertmod before enablecores? or does it not matter?

thanks for reply

EDIT, I read it again, if i have to reboot after enablecores then i should do that first and bertmod after. Il let you know if there is any improvement. I'm reluctant to try 0.98.1 because 0.98 WAS working so well for me.... I just don't know what changed....

I was even told directly over the phone that my status as a customer was less important compared to those who ordered in June/July, because I didn't help them fund the initial costs. What kind of a company says that to a customer 

Wow! What a despicable attitude to customers! That really is disgraceful.

But guys (i don't know how to say in english but I try, maybe someone can undestand it) look into yourself and a bit use your brain. What he got on the phone is the raw truth.

This is true, we took a lot of risk on these guys and those of us who got in early + got our units delivered are doing OK with the recent upswing on the exchange rate.

I respectfully disagree. I got in early (day2). I paid in June. I got my order more than 14 days late.
I have, even with the recent upswing in price, only made half of the money invested into it back.
I was lied to on the phone, per email. I requested a reasonable compensation for the delay, which every company should do if they want to hold their customers. The response was more than insulting in my eyes, going for the b2b TOS which are clearly not legal in any state of the eu and trying to shift the blame to me. Even if they had only compensated me with 8 btc per Jupiter ordered (which at that time woulld have been under 1k$) I would have been a happy customer again.
But they chose to stay silent after that. I personally won't buy anything from them anymore as long as the only payment method is preorder and their next gen is out and will continue to buy used miners instead. Also I have to agree that the units are overpriced. We knew that when we bought them, but I expected them to deliver on time. If they had, I certainly would not complain that hard. But seeing how people got 10+ units in one order on time really pisses me off - a serious company would have stated production problems and would have sent a reduced amount to highten equity for the community. I doubt someone with 12 units would have complained if only 8 came on the first day and the rest a little later. But the others who got their 1 or 2 or maybe even 3 units 14 days late are the ones now trying to break at least even while those others are happily hashing away with 30+ btc per Jupiter.

I can say for certain that CS has lied to customers regarding compensation for late hosting setup.  Customers were to receive compensation for the late setup (not the 5btc crowd), then suddenly nothing.

Hosting has a heap of problems, they will be discontinuing soon because of heating issues etc. (cases are not rack mountable). Also people been shifted to eligius without any notification

bertmod last, and dont reboot after bertmod, just restart cgminer

I've seen this with 3 Jupiters on 0.98 after 3-7 days
in 2 cases restarting cgminer from within cgminer worked (you can't do that with knc hosting)
and in 1 cases i needed run enablecore, and reboot (you can't do that with knc hosting)

now all are back to their usual hash rate

GOX just hit $305.00!

hmmm...its a "trap" has to be..I'm neither lucky enough nor "evil genius" enough to pull this off (this is MY correct choice of getting a Jupiter by the by)..

so....some kinda fiendish universal plot you are all in on..to coax me to that so called "happiness" place people talk about ..yeah that's it BFL is behind the curtains on all this...

must be it....wait..who are you guys in the black suits....and what is with the helicopter..no wait.....argh.........klunk....

Are some people getting paid to talk positive about KNC?

I think some people ARE KNC.

Avenger has made several posts which are negative, yet 100% accurate. If that's poisonous he didn't make the poison, he's just reporting it.

On a brighter note.. I just woke up to see us hovering around the 300 exchange rate.  That I would never have guessed even a week back.

Someone will be along to explain the other side of that soon no doubt lol

It's been explained so many times already, I'm not sure it's even worth trying anymore. Either you get it or you don't. Still, I am happy about the price increase though.

Actually its the opposite. Increase of bitcoin exchange rate means that more even hashing power will be sold and you will mine less BTC, and mining BTC is all the machine does and what you bought the machine for. If you wanted a dollar profit speculating on a BTC price increase, you should have bought (or held)  BTC.

[demonmaestro]

I have bought btc and i have mined btc. either way I could care less how i get btc. Its a hobby for me..

I think some people ARE paranoid.

When you have a large production run of any product, there will be some units that have problems.

The people who have problems are many orders of magnitude louder than the people who don't.

In the end I think the vast majority of people, positive or negative are just providing feedback on their experience and trying to help each other out.

[FoolPartedWithMoney]

Are you guys kidding?
I was contemplating a November Jupiter...
and went thru the numbers, and made all the predictions in my usual way, and I came to the conclusion, that a November Jupiter is definitely worth it, and spent the 17.6 BTC, of my 27BTC I made in the first 20 days, to order it moments ago....
And I'm stoked about it...
Think about it...
The November units may even deliver before HF & CT get their act together!

In a hindsight, it must suck to lose about a thousand bucks in less than day.

I am using the executable ckolivas most recently posted about, supposedly 3.7.1

I don't have an ARM development machine nor know a thing about cross-compiling on Fedora 17 or 19 for ARM machines.

I have run over 48 hours before dying  sometimes, even over 72 maybe. Actually maybe it didn't die like this until they released a release that had a ckolivas version in it, hmm I wonder if that one is/was stripped? Hmm... I am not sure when I first encountered this "mystery dying" problem, seems liek it ran quite a few days originally.

I killed it to try running strip on it on the beaglebone, that is how I discovered they dont' seem to have strip on that. But now it shows in web page as 282 so maybe its not goign to lose much by using --lowmem option afterall. I do wonder how much RAM the debugging symbols are consuming though...

Hi Mark, just a FYI

Another 24 hours running the same setup (0.96 with 3.7.2 cgminer) and my memory footprint hasn't changed cgminer is still fluctuating between 23% and 25% memory.

However, overall system memory has dropped to only 127MB free. So something is using up memory on the system over time, but its not cgminer.

If I had only bought bitcoins when I couilda woulda shoulda instead of buying my miner .... I would have sold back for fiat the moment it went up 5%!
