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.

you can avoid that if you use the P within cgminer.

Thats what I did and never had the issue.

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

In my testing, lower temperature doesn't seem to increase the performance of my Jupiter. I've been trying to figure out why my hashrate dropped overnight and decided to remove the case and point a big fan at it which dropped my temps from:

ASIC slot #1: 51.5 ℃
ASIC slot #3: 57.5 ℃
ASIC slot #4: 63.0 ℃
ASIC slot #5: 54.0 ℃

to:

ASIC slot #1: 42.5 ℃
ASIC slot #3: 47.0 ℃
ASIC slot #4: 42.0 ℃
ASIC slot #5: 35.0 ℃

but this did not improve my hashrate at all. Right now I'm not sure what to think about my unit's behavior:



As you can see yesterday it held at around 530GH for around 12 hours before dropping to 450GH over night. After applying .95 it increased back to 500GH but I can not get it back to the 530GH levels I was seeing yesterday even with extra cooling and reverting back to .94. It did this the day before where it was running fine before dropping to 450GH but a simple reboot returned it back to 500+GH. I guess I will just be happy with 500GH and wait for a new firmware but thought I would share the results of my testing.

keep the cooling and got back to .93

do your boards have 8 or 4 VRMs?  with 4 VRMs it will run hot but recover much better running .93

looks like I will be going back to .93.   when I went to .95 on one miner, it dropped the watts from 770 to 470 with just a 30 Gh drop at first..  but now it dropped 20 more to 470Gh.  I rather run it hot and back to 520Gh


also, when running .95 I added bertmod's firmware and found out that one of my dies is terrible.  shows 24 cores off.  cant tell when on .93 since that version of bertmod doesn't show cores

Now on my balcony the temp is 3℃, and I have this:  

ASIC slot #1: 38.0 ℃
ASIC slot #2: -
ASIC slot #3: -
ASIC slot #4: 27.0 ℃
ASIC slot #5: -
ASIC slot #6: -

How come there is more than 10 degree difference between chips

Switched my hosted Jupiter to eligius and I'm now getting close to 500 (around 480 450 420).

Thank you for .95!!! Can't wait for .96!!!

My slower machine running at 375, tried Eligius says 400...  I don't think it has anything to do with the pool.  Bet one of the 4 boards is bad.  I bet I would get around 375 if I unplugged one of the boards on the jupiter..

At the moment I can get 450-460 if I click the save button in the portal and have it soft reset.  That lasts for about 20 min, then it drops down to around 400.

I really wish there was a phone we could call to get a hold of whomever is working in the data center.  Staying up and calling customer service @ 4am only to talk to someone that can't do anything is fairly frustrating.

However, today was a good day.  From 140/150GH/s to 400GH/s is definately an improvement.

Welp! I just posted my Unboxing and First Look video. I also made a post, but I thought it would be good to post it here too! Review coming soon!

P.S. It cam with a fan knocked off, but other than that, it's fine. Hashing at a stable 530 Gh/s on firmware 0.95. Enjoy the video!

I agree, great day!  I feel KNC will fix and deliver now that we have had a great day.  =)

The firmware 0.95 is not good for Saturn (with 8 VRM per board).
The average speed reported by cgminer is greater than before, bu work utility (WU) is 3700+ instead of 3900+ and the pool reports lower hashing (220-240 instead of  260+).

[plasmoske]

0.95 is definitely good for me. Got my host details last night. Logged in and connected it to Eligius pool.

For my Jupiter, it was only running at 16GH/s and then jumps to 150GH/s and then maxing out at around 270GH/s.

I already knew of the performance issues they're having in the datacenter but sent them an email anyway to notify them of my miner issue.

Anyhow that was like 3am. Woke up this morning and checked Eligius. During the night, the graph explodes from around 250GH/s~ to about 480-610GH/s. Oh yes!

Then opened the knc website for any news, and yeah seems like 0.95 was released and applied to all hosted customers. Awesome.

Happy for now.

In simple terms a supply can be a current source or a voltage source.  The power supply might show characteristics of either/or given that those are not simple devices.  If its design says that at a given moment it needs to provide X amps of current to maintain or reach Y voltage, it will provide that current.  If for some reason it does not know the voltage has been approached or reached, it will continue to provide that current unabated until it voltage limits.  Until it knows that the required voltage has been reached it could source current that could drive the voltage above the specified max voltage of the circuit capacitors and BANG goes the capacitor exploding and outsourcing a gas that smells just like electronics burning. ...

With you right up to the point where your voltage-regulated PS starts putting out too much voltage.  That's not voltage regulation, that's crap regulation, AKA broken/badly designed PS.  Not that you can't come up with an inductive/weirdass load that can spike the output of a power supply -- you can, but that's not the PS causing the spike -- it's the load.  A voltage-regulated PS has a bunch of voltage deviations -- noise, drift, min/max -- a properly designed PS won't source outside of the values in its data sheet, or it's called "broken."
No black magic here.

Same here on a Jupiter. Higher hash rate (20gh/s), lower WU (400). 20% lower payouts on .95 in all 5 blocks since upgrade. I'm going back to .93

[loktang1125]

the 0.95 are working fine on my jupiters

Thanks for the update. Please keep doing this daily!

Now about the sequence of orders, it seems that hosting orders are on halt, for example I have 280x and 281x and both are still on paid while higher numbers are already being processed. Both were paid within minutes after ordering. Hosting was ordered and paid later, but that shouldn't matter IMHO.

could it be you hosting guys are in the "paid" status only because the hosting is working so badly.. and up to their statisfaction.....at the point stuff works they will then start hosting..and any of this 100gh hashing you getting now just plain don't count because the hosting facility is not up to snuff

hmmm...are you guys still getting BTC or has that stopped?

anyway hopefully this is correct and you guys will get reimbursed and your status changed at that time

just trying to give you a bit of hope but would be my 'guess"

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

HAHA, who will be the first!?!?!

There can ONLY  BE ONE who is first (dramatic clip inserted here)

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.

[Searing]

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]

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

[Paladin69]

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.

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)
