manufacturing time... takes less time to mount 4 converters than 8....times that by a few thousand units.....

You have to be fucking with me right.  They are automated assembly machines.  We are talking a half a second (conservatively).  It isn't like these are hand soldered.  The assembly house is going to crank out thousands of boards a day.  If KNC had a big enough run a good assembly house could do tens of thousands of units per day.  The automated board construction isn't the bottleneck, it is the rest of the mundane manual stuff like bolting down boards, connecting wires, and mounting heatsinks which takes a "long" time.

I'm running 0.93. Just tried to upgrade to 0.95, and it seems to work, but after restart the web interface still says that the current firmware revision is 0.93. I tried to upgrade (downgrade) to other versions but it's the same.

It is possible that the upgrade was successful and the web interface displays the wrong version number? Is there a way to check firmware version through ssh?

at least you can access the miner page/tab....I cant... i get "ERROR 500 Internal server error"
update page works, status page works, networking does not, and miner page error

My Jupiter is scheduled for delivery today. Of course I bought a Corsair HX850 - is there any *safe* way to use it, or should I not even plug the thing in?

What if I power on the HX850 and plug in the PCI-E connectors one at a time?

NO! Never plug one at a time whilst on. and please step away from that PSU if you are even contemplating that!!

[FractionalReserve]

Then why not leave the 8 VRMs on for that point??

why are you dodging that?  what was the main gain for everyone on taking off the 4 VRMs??   You could keep shipping with 8 until you tested taking off 4.. .how can you try to keep avoiding this logic?

Simple.  KNC chose to use an off the shelf power module.  This means rapid prototyping but it also means higher cost.  Those modules run $25 each.  8 per board means $200 per board in cost just for the power supply.  That is $800 per Jupiter.  If they leave 4 of them off that is an extra $400 in profit per unit.  1500 units @ $400 ea = $600,000.

There is absolutely no other reason to change the extensively designed, tested and fully operational boards right in the middle of peak production.

Of course thats the reason.

As I understood it they ran the 8 VRM boards with only 4 VRMs activated and without any problems.

When they skipped mounting 4 of the VRMs in production, suddenly the Voltage levels differed.

That has now been fixed with Firmware 0.95 where Voltage offset function in the VRMs has been used to give correct output.

They had an issue, fixed it. No need to discuss this further?

If you have 4 VRM boards DO UPPGRADE TO 0.95 !!!

So even with the much better FW .95 you still wouldn't chance it?  How about the 1250 series?

When I added my backup pools in CGMiner itself, I broke the web interface. I'm assuming that's the common cause for most people.

Did I miss something?  What is wrong with his PSU?  This thread is moving too fast.

KNC is claiming that Corsair (one of the most trusted enthusiast brands) "ramps up current too quickly" and that is why a mining board (powered by Corsair PSU) blew a capacitor.  Of course the fact that a high current switching supply SHOULD operate that way should be ignored.  The obvious explanation is that Corsair doesn't know how to build power supplies.  

No KnC, ORSoC and General Electric's Critical Power Specialist are saying this particular model has an issue on reset that it surges current for 30 seconds.

[The Avenger]

We all bought an unrefined product did we? Odd, I didn't see those words or anything like that when I paid for mine.
Not in any of the back patting videos or interviews either.

We bought a miner that we were told confidently would have margins upon margins capable of 400Gh and even today no-one has said that this (and the oct 15th date) has changed. Except of course to up it to 550 on the site and most promos ...which currently is false advertising ..as the past 20 pages here bear witness to.

As for all this shite about power consumption...right now is that a big priority to get down? I'd rather have a hashing rig while it's making enough BTC to make a few quid power bill extra irrelevent..later on the power consumption will matter more but not initially compared to a working rig. As long as the PSU handles it, we can wait for a firmware fix to get it down. Hashing reliably without smoke is the priority for users.

The sarcastic tone of Oramas post amazed me, people using fans to reduce temps ..planking? It worked. How bizarre is that? More to the fucking point no-one was talking from KNC end despite much asking...so what else were people to do? "We have a specialist flying in and we'll get back to you as soon as we know something."  < see, took me 3 seconds to type that, and even some poor sweaty overworked KnC human could manage that surely?

The way to deal with trainwrecks like this isn't arrogance, sarcasm and silence ..it's communication and apologies and in many cases here where buyers have been so badly let down with multi hosted jupiters...fair compensation.

I wont deal with KnC again, nothing to do with the rigs, it's the denial and head in the sand stuff I can't be living with.

Timmers you are being sensitive. Avenger I'm starting to believe you are a troll. Of course it's unrefined as you well knew. You knew perfectly well they were delivering a product to be placed in your hands in an expedited fashion upon receiving the chips. As such margin upon margins were in place to ensure no post chip receipt refinement was required prior to you being able to hash. Obviously this would mean improvements would then succeed the initiation of delivery, and will continue to do so. There is yet more to come. This is not a first for just Bitcoin mining, this is pretty much a first for the entire IC industry. It's insane. To get this, this right, first time, on 28nm tech is unheard of. Those involved; fab, suppliers, backend, etc. think this is remarkable, and it is.

I ask direct question and you avoid them. It's you're favourite thing to do.

We are talking about shitty communication, lack of updates. Your "sarkiness" and trying to tell a bunch of smart people a PSU is the problem.

And in response, you go rattling on about how remarkable production is! Your answers are stupid and avoid anything pertinent. You are more or less the definition of a troll.

Would you pull out a ram stick or graphics card while you're computer was still on?

I meant using a common PSU like the HX850 in general.  I'm not refering to whatever the hell people are talking about with connecting one pci-e at a time.

Excluding this PSU sounds silly.  It still isn't safe with FW .95?

[DeathAndTaxes]

Yes.  Even a CPU.  In a hotswap capable high availability server

I think he was more asking is the PSU ok.  The fact that someone wanted to energize a power supply and THEN connect wires well I mean that is just asinine.  Some people should just buy Apple products and treat them like magical toasters.  Plug it in, use it, throw it away.

Sure there can be a further fix, but that PSU does something other PSUs do not do upon restart after having to remove the ATX coard to reset. Fact, and now a proven one, by GE themselves.

[DPoS]

If you have 4 VRM boards DO UPPGRADE TO 0.95 !!!

one of my miners has 3 boards with 4VRMs and 1 board with 8 VRMs

I guess I should just roll the dice that it will be happy or would this make that 8 VRM board act odd?   Did anyone with jupiters with 8 VRM boards upgrade yet?

Again with the unheard of stuff..... No one here who did not get his day 1/2 unit is sensitive. It's called business because we want to make a profit out of it. This is not some apple fanboy stuff where you waste 1k for the looks. It's a decision to make money with a high end product for both ends. That said, they should not have told people shipping at day 1/2 of production if there was even the SLIGHTEST chance of them being unable to deliver on time. 1 Jupiter unit - in hand on time - could have made me 2,5k$ by now.
And all that without getting some sort of statement from them and an offer for honest compensation?
And you call people sensitive? Please, I call not calling them and screaming my lungs out through the phone having balls. I will do that btw. on Monday 2.30 p.m if there will be no shipping notice.

Don't plug it in.  Go buy something else at your local electronics store.  It will pay for itself in 24 hours.  You do NOT want a downed machine currently.

Also - .95 seems to be working very well for me:

 (5s):585.5G (avg):556.7Gh/s | A:65024  R:512  HW:3533  WU:7784.1/m

what was your previous hash rate?

[DeathAndTaxes]

Yes the PSU is a problem, are you saying you are smarter than these guys and the guy that designed the VRM itself, and has just confirmed the HX850 surges upon reset after triggering it's safety?

Good thing no Corsair PSU has ever reset on any computer system anywhere in the world prior to today.  If it had it would have blown the caps in motherboards, GPUs and other components. Very lucky for Corsair not a single power supply in the field (out of millions) has tripped before yesterday.
