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?

er no I would not if what bitcoinrama said is true that they have a guy from corsair tech guy to check it out ... looks serious enough they
have corsair up in the air

anyway my 2c worth just grab another diff brand imho

[Searing]

Is the OCZ ZX series okay then?

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.

ah crap I have a seasonic

Just repeating my post on the other thread.

0.93


0.95


231w vs 231w. Looks like I'm staying with 0.93 with its higher WU/m.

[Searing]

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

that's what I have......so please answer our question here (still have time to send it back to newegg ...should prob do this anyway for something larger even if the model I have is OK in hindsight)

[Searing]

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.

I went from ~410 to ~510 BY COOLING

yes, you are in denial

they should of tested and created .95 before saving money taking off the 4 VRMs

FACT

just asking so don't take my head off ..I know zip

but have you upgraded to .95 and if so does your cooling seem to improve on that as well (can't hurt imho)

anyway curious

and on a side note I gather if you do manage or need to send your psu back (again I have seasonic so prob safe) prob a person should jump it up from 860w seasonic or whatever to say a 1000 or more to be safe at this point in time (if you have to send you stuff back) would that be prudent?


Searing

Are you talking about the platinum seasonic? I have a corsair ax860 which is the same thing, but I did not get my miner yet. I am not really worried about this PSU, though. I would be concerned with the seasonic x-850 gold, but not the seasonic platinum ss-860. Our PSUs are made better with protection features or something.

Got my stuff in today.  One of my Jupiters was working for about an hour then shut itself down.  It refuses to power itself back on.  It will briefly attempt to turn on for about 3 seconds and then it shuts down again.  I thought maybe it was the PSU so I swapped it with another but that isn't the issue.

PSU's = OCZ ZX 1250

The other two run fine.

what does it look on the inside?

[r3animation]

Btw, just figured my Saturn is hitting 0.85w per GH.

[xstr8guy]

Order #40x, ordered and paid June 3rd... "Day 2"  , shipped Oct 9th, delivered Oct 11th to US West Coast.

Front 2 fans arrived knocked off, a mess just like the other pictures you've seen. Box wasn't badly damaged though.

Heatsink bent slightly. Nothing a few hand tools couldn't fix. https://i.imgur.com/QPYnXmv.jpg

Using Corsair AX860... no fires or pops or anything nasty.

Started up, applied 0.95 firmware, pretty easy.

Temps are a little hot for my tastes... we'll work on some airflow https://i.imgur.com/F386xnl.png

530gh/s+.. seems to be rising slowly! https://i.imgur.com/ul7bhuI.png

Measuring 576W @ the wall using Kill-A-Watt

Probably my last post in this thread, back to professional lurker status. Bye

That's the AX860, not the AX860i, correct?

Thanks for sharing!

the one miner that was roasting and I cooled it and ran .93 to get it stable at 520Gh was running 770watts on a 850psu

so.... I put .95 on it and it lowered everything.  300 less watts, 490Gh and 10 less degrees C on all boards...

but, soon it dropped to 470Gh so I switched back to .93 and had crap luck since.

I've done a lot of experimenting on this miner the past few hours and it is very odd to see that sometimes one module will be stuck turning off and turning on 12-24 cores and then sometimes another module will do it and the other wont... but atleast one does.  It is only the back right and front right that take turns doing this.  I put more cooling on those both (propped it right against an window a/c unit) and no luck with .95 or .94

worse is that going back to .93 will get the dreaded FPGA lock up loops now... so it seems I can't run the one firmware that was able to deal with whatever wack-a-core issue that is with this miner.

so I am back to .95 and it has dropped down to ~400Gh stable which is a joke.   KNC lives in a fantasy world where they just attack one issue and think they cured cancer each time.

I'll probably try to get .93 running again, it might just be luck of the roll with restarts

Some troubleshooting steps I've taken.  Nothing is consistent but I might be on the right track.  All the cases are off.

Attempt #1
~ Unplugging the ethernet cable allows it to boot up from a hard shut down, oddly enough.  After a few minutes then I plug it back in.  It mined for about 15 minutes and then shut itself down again.

Attempt #2
~ To answer your question about looks, the heat sinks inside lean back and are not level like the others.  Noticed one is sorta loose.  The other 3, while leaning back, are tight to their boards.  Unplugged the PCI-E from the loose one.  Turned it back on.  A red light is on the front instead of green but the other three boards are mining and have been for about 30 minutes.  Will update...

---------------------------------

Side note...the PSU connected to this particular machine that is having problems is very warm.  The other two machines aren't warm like this one.  Will test how warm it is in a while if things are still mining with only 3 of the 4 cards without shutting down.

Side note #2...One of other machines that have been running all night just fine, one of its case fans are running at a very low RPM and not emitting any cool air.  Maybe KnC can send me a replacement?

---------------------------------

UPS is throwing these things around rough.  Boxes were damaged.  No packing peanuts/balls of any kind still.  Just the piece of packing foam on each end.

Same here, I'd been having SERIOUS problems but .95 has finally given me the product I ordered.

[ecliptic]

Why the fucking shit did they cut the number of VRMs in half?  Why is half of my PCB assembly unpopulated?

Graned this thing runs cool as shit, like, not above 50C anywhere cool, but that only tells me the clock limit is due to the (lack) of VRMs and/or lack of decoupling capacitance.

What the fuck is going on here?

[DPoS]

i think i am a lucky one , i put .95 on and i got 550ghs

glad for you, seems some miners come out ok.   My other one is still running .93 and avg 520Gh

Looks like I will now be a thorn in KNC's customer service over this.  I was content on tweaking my problem miner and getting it to run on .93 while cooling and 770 watts but with Bitcoinarama's incessent promotion of .95 for miners stuck with 4 VRM boards I made the switch to give relief to my psu...

He boasted and boasted that everyone is a fool to run pre .95 and cool their miner.   No matter that I was stable at 520 Gh for well over 24 hours.. nah.. fool he says.

sorry I will push this against KNC until they send me another miner over this.  I really have nothing better to do but bother them now

[loktang1125]

that's how i place them
it's decrease about 3-4 degrees after i lean them

[mininganon]

If I have corsair HX850 PSUs for my miners should I immidietly change them or should I wait for official info?

   



in a post a bit back from this thread (look for it sorry can't seem to find it)

there was a method to wait for a bit then unplug psu from miner ..then run psu alone w/o miner then shut it down and re plug in after

don't quote me but a few pages back in this thread



myself i'd send it back if you could

hope my seasonic 860 is ok and not the same mnfg or some such

Searing

What? I ran an HX850 for days on my Jupiter and nothing exploded although out of habit I wait till fans stop which is 10sec to turn back on. Have since swapped the HX for a TX I had already.

Edit: Guess I should add that my miner on HX drew 555wats on peak start, I have 8 vrm per module. Don't know if it was just the people who run 900watt that are vulnerable or what with the HX850.

Now imagine having no access to your miner, no return emails and having to wait until 4:30am to call their customer service to talk to someone that can't help you.  All the while mining ~400Gh (an admitted improvement over 150 from the last 2 days)...

I'm sure they will eventually make things right with me, but it will be too late.  After all, I've now been mining for 3 days for grand total of .8 BTC (yes that was a period before the .

I really just want to talk to someone that has physical access to my miner and can troubleshoot it. In my opinion, people that paid an extra $2200 for hosting shouldn't be worse off than those that had them shipped. 

[Searing]

and on a side note I gather if you do manage or need to send your psu back (again I have seasonic so prob safe) prob a person should jump it up from 860w seasonic or whatever to say a 1000 or more to be safe at this point in time (if you have to send you stuff back) would that be prudent?

thanks ok i'll just keep the seasonic 860 80plus platinum for the Jupiter and I have a 660w seasonic 80plus platinum for the Saturn

whew..i was like 1 click away from getting the corsairs....(better to be dumb and lucky I guess)

[ecliptic]

There's a very good chance the 8 VRM boards will be able to overclock / boost performance FAR beyond the 4 VRM boards.

These are not thermally limited as-is on 0.95.  If they are limited, they're limited by VRM current or perhaps decoupling capacitance or other

Prepare for further shitstorms, anyone with a 4 VRM board will be like a cripple trying to keep up against Usain bolt

Oh and those VRM modules have the board level connections as BGA-style underneath the PCB.  So you're not adding any components yourself!  So go fuck yourself, everyone who doesn't have a reflow oven
