Is the OCZ ZX series okay then?

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!!

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

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?

Sorry my bad.

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"

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.

hmm, i have to physically start cgminer thru ssl because the workername was input incorrectly from the factory, which may be the cause then?...  it's catch22, because i cant change it on the gui...lol

Yea it is a catch22 situation but at least I have backup pools setup now.

That part of the web interface didn't really give much info anyway.

According to KNC only Corsair makes booby trapped power supplies.


Then again Corsair doesn't actually make power supplies Channel Well and SeaSonic do and between the two of them they make a good portion of the power supplies on the market from just about every brand.

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.

+100000
Totally.

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 you go rattling on about how remarkable production is. Your answers are stupid and avoid anything pertinent.

Seeya, I answered all your questions politely yesterday despite your name calling, and abuse. You're a blatant troll now, you twist absolutely everything negatively. 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?

Two of the boards that burned were NOT running on a HX850. Explain that with your theory?

That other PSUs also overload current upon reset, instead of a gradual ramping up. With the HX850 upon reset it only lasts around 30 seconds after the safety is triggered and reset of the ATX cable is required to restart the PSU. After which if turned off and on again it behaves as normal with a gradual supply of current instead of overloading the cap.  I think Erschiessen has a generic brand psu. That may have been based on the HX850. I do not know. I'll get a better explanation from the GE guy tomo, but it's 10.30pm here, and I've agreed to let him in at 9am. So I really do not need to be on the receiving end of abuse for keeping you updated, and I am not an elec engineer myself, but yes it is particular PSUs. Now I have a bullshit journey to where i'm staying to get minimal sleep and turn around to let this guy in so this issue can come hopefully to a conclusion asap.

FYI, my Jupiter day 1 customer 1-500 is running hosted since 2 days now at an underwhelming 100 GH/s average and my order still says PAID, never went to "processing" or anything else.

Maybe you will get lucky and get a second Jupiter. But anyways, contact the hosting facility and ask them to turn of its power, open up the casing, and check its cables. You pay them for doing stuff like that.

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?

Previous hashrate was about 20 gh/s less.  The pool stats seem to be around 540 gh/s

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.

Is there a "safe" list?  This is like shooting in the dark.

Kinda, the safe list is any PSU that doesn't surge upon restart once a safety reset has taken place. The units have not been in the wild or been tested with as many PSUs This will now have to commence. It wasn't anything that could have been foreseen unfortunately. For sure the Cooler Master V850 is reliable and the most tested PSU. FWIW the entire hosting facility was almost kitted out with HX850's had it not been for the inability to acquire them in volume at the time.

[rrrix]

How about a Corsair AX860? Been calling around, local store has this a few miles away. Otherwise I think I have a loooong drive after work. I live way out in the mountains

I would kill for that.  After today's upgrade to .95 my hosted Jupiter still isn't able to maintain 400GH/s (I just saved the config in the UI to force it to 'restart' when it was running @ 308GH/s)

I would guess that the configuration is still saved in a text file you can hand-edit.

is it possible to putty in twice simultaneously?

Those kinda suck...not bad but not brilliant.
XFX psus are all Seasonic inside and cheap, NZXT Hale series, Fortron FSP Aurum, Corsair AX series (not i)...Seasonic psus obviously.

just fire two putty instances and login in. you'll get to "parallel" session in two different windows. remember linux ha has anchestor unix.

What denial? What head in the sands?? They worked their asses off to improve the issue, and ignored the FUD. The extra fans just waste electricity. The temps quoted from Bertmod were from the VRMs not the ASIC. Please explain what trainwreck exactly? They, in a week have delivered more hashrate than BFL have to date, and more boxes than Avalon ever achieved. They have just released an update that massively improves hashrate. It was a firmware, not a cooling issue. One week. Fair enough if you don't want to deal with them again, their engineering partners on this project think they are incredible, really. That's not hype.

Think about what you are saying man!!!

It is great that the model in question is under rated.

A PSU's ability to deliver 'current' has absolutely no bearing on a device drawing too much.
Get some guidance please when discussing this current issue.

Did you mean 'voltage'?
that might make sense.

We are discussing a technical issue the details matter.

OBTW I do happen to agree that shipping 4 unused (unusable?) VRM's per module was wasteful.

I'm really not hating on you here bitcoinorama.
I'm trying to steer the technical discusion to the correct details.
