I think they say it is a firmware issue mostly because the hardware is basically the same in all the units.

Yeah where is that idiot Bitcoinorama when you need him?

Imo, this is a multi - pronged problem. Not only was the packaging inadequate but more importantly we have a design problem. going from 8 to 4 VRM was a mistake.  Double the phases means half the current, means smoother power, means more stability for over clocking, means less heat, means less blowing up.  I doubt it's just firmware.

@Cypherdoc

Why are you, a HashFast representative, in a competitors thread criticizing?   I'm not saying there isn't criticism due, but this kind of stuff really makes HashFast look bad.  You might want to think about that some...

I'm not a HF rep.

What I'm doing is no different than what you were doing criticizing in my thread.

But, hey, Bitcoinorama claims he's all about ethics. I'm sure he'd understand your dilemma and get you a refund, right?


What about your ethics of trying to make KNCMiner investors feel bad about their investment?

After a night of hashing I must report disappointing performances...

Given that the speed is between 450 and 500 GH/s, my Juliter draws more than 900w at the wall, with high temps and frequent Cgminer reboots.

It seems clear to me that where the first "batch" performed well, this second release (with half of the components on the board) has a lot of issues as many are reporting here and on KnC forums.

And YES I've upgraded the firmware, and YES it's getting proper cooling. And YES I had to remove the top.
And YES I tested the whole set of firmware sets, with 0.94 being the only that's working almost stable.

As a last note, I'm using a Seasonic Platinum PSU, not the Corsair that, assuming the rumors from KnC forums again, is giving some power issues (guess why, it's 860w certified and the Jupiter wants 900 watt!)

Should we do a meanwhile a PSU survey?

P.s.
I forgot to mention the 20% of hardware errors

 Shocked   I hope mine is better...

This is really a bad error! only half VRM?HuhAngry

Oh,  so I'm the first one around here to be doing that? These are rough parts around here in case you hadn't noticed. I sure did back when I endorsed HF.

Seems people can dish it out but can't take it back.

meeh, I'm scared to open this thread and read couple of pages back - it is getting worse day by day and it seems that nobody except KNC (maybe some hardcore fanboy) is happy with his miner.

almost everybody reporting packaging issue, huge amount of HW errors, unstable FW, overheating and there are also some photos of burned boards. guys with hosting still waiting and the luckier ones mining with 20% of promised performace.

lack of communication from KNC side still continue, lot of guys here waiting days and days for non-specific common mail, without any new information or added value.

I paid 86BTC and today it is 7 days, when I have my Jupiter at home. I should be lucky one..but honestly, If KNC offer me buy back of my jupiter for 70BTC, I will do it right now. sad. Situation of majority here really sucks. Strong nerver guys..

I hope that's right because it looks to me like they have a shitload of bad chips and only found out when they arrived and didn't perform, and are now having to test them as they go which is slowing them right down. They definitely didn't have time to test them before they announced that happy hashrate in the video and sent a bunch out. I remember people saying that rigs arrived with no activity on their pool accounts too, so maybe the first time they ran in anger was when they arrived at the customers?

If KNCMiner doesn't ship both of my Jupiter units by the end of next week or refund any money, then I might kill myself for financial reasons.

People overvalue one or two weeks. In fact, your miner will make only slight return in two weeks.

Cant speak for others, but Im mainly curious how you will react when HF runs in to similar problems and delays. Their schedule is every bit as unbelievable as KnC's was. HF chips havent even made it through the fab yet and already they are running a week behind schedule making their october promise all but impossible.  The most tangible thing we've seen from HF so far is renderings and a FPGA simulation, not even running on their own PCB. Ie, about what we've seen from Cointerra which isnt due for another 2-3 months.

Time will tell if you turn out to be a hypocrite or not.

With the current difficulty increase rate, you can only mine 70% BTC if late for 10 days and 49% BTC if late for 20 days.

I've already said I'll eat my words if the f*ck up is a bad as this. I don't think being late is the issue here. It's mostly product design.

But I really don't think it will be this bad. We'll see though.

Maybe they can make a firmware where cores become disabled, but then they are re-enabled quicker or something, or maybe a firmware where disabled cores are enabled, but at 80% of what they were trying to do , or something.

Luke-Jr will have a look at it next week. The source code will be released. He is the author of bfgminer. But yeah, they should have given him a free machine and let him do testing. He could probably do better firmware work than they are doing too.

Arguably, HF already fucked up about as bad as KnC.
KnC promised end of September and only a few days later at least a fair number of users received their hardware working better than originally promised.

HF's current one week delay (assuming it ends there, which I highly doubt) would make achieving what KnC did, shipping less than a week late, over spec to at least a tangible fraction of their customers, very unlikely. And the real pitfalls for HF are yet to come.

Remains to be seen if the problems for the rest of KnC can be solved, we dont know that yet. Its at least feasible a firmware update will fix it for most other customers.  Personally, I doubt it, but I doubt just as much that HF's execution will be better.

Cypherdoc - FUDcaster General, coming to an unrelated thread near you very soon.

Actually if you look carefully, I never came into this thread to criticize or spread fud prior to now. That really doesn't make sense if I was trying to disrupt their business. In fact I was one of the first to congratulate them a couple of weeks ago after the demo video.

Buy yeah, you know what? I am a big protector of bitcoin in general and when I see any company screw up the economy after having collected so much money and behaved so arrogantly Imo,  I'll let them have it.

Did you let BFL, "have it" then?
