So is there a confirmed "safe" brand of PSU to go with, or just anything but Corsair?

what about seasonic which is the version I have are they related in anyway? (they are still in the box I can send them back to amazon at the rate stuff is gonna show up here if I need to)

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?

No official announcement yet but firmware is already there

I wonder how long a Mercury would take to generate a share on Slush's pool.  If the new assembly testing isn't long enough or lucky enough to generate a share it won't register as having been fired up.

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

And here he's correct.  If the VRM is designed to withstand 100 C, cooling it from 80 to 40 makes no difference.  

Well it depends.  No device is fine at 99.99999C and then explodes at 100C.  The hotter a component gets the less efficient it becomes that means more current is needed and more current means more heat which means higher temps, which means lower efficiency .... and the cycle goes on. 

All the problems seem to be limited to the rushed "lets cut the number of VRMs in half" mid production modification version.  If the 4 VRM version (doing the job of 8 VRM as designed) is running at high load then even a modest amount of cooling could improve performance.  Not saying that IS the case just pointing out it could be.

can't find the quote either form knc or bitcoinrama

but was there not a quote a few pages back that .who is it Orsc  THE CHIP designer half of kNC  not sure of name spelling? .....there people have come in and are now running the PLANT etc

so maybe these issues will go away now? knock wood....bring in the big guns

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.

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

the support page has something like called a reboot patch

not sure if it applies

hard reset I guess is your other option


looking good guys...I want you early order folks to have this all fixed and at 500w and 600gh by the time I get my Jupiter 304x....its all about me don't ya know...

then plug it in and martini time.......lab rats I salute you! 

(ducks hey don't throw stuff in chat)

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

[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.

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

http://www.corsair.com/professional-series-gold-ax850-80-plus-gold-certified-fully-modular-power-supply.html

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)

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)

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.

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.
