And now, "Gay Life On Bitcoin", a venture by 2 loveable users, Cypherdoc and Avenger.
Let's all donate BTC and send these two on a honeymoon. Anything to get them out of here.

And how much skin do you have in the KNC game MrHempstock? Oh yeah, 25GH. That's kinda sad and pathetic. And actually, just a little gay.

LMAO not near as gay as the guy who gets a hard on every time there's even the perceived observation of KNC falling short in ANY way.
Correct me if I'm wrong, guy.
Yawn, I ain't bothered what you say MrDampCock.

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

I'd personally change bro. After their reset they supply peak current without ramping for approx 30 seconds is what I understood. That pops the cap, and so far it's the PSU that is most likely to cause this issue. Most other PSU's once reset gradually ramp current.

This is an alarming issue and needs to be addressed by KNC with an official announcement.

Seasonic manufactures the higher quality PSUs for Corsair and MANY other vendors.  The HX series is one of them. Seasonic is considered the premier maker of PSUs by many PC enthusiasts. So it's very surprising that their PSUs are possibly causing such a horrible problem.

Here's a comprehensive and current list of who makes what in the PSU market.
http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913-4.html
Yep.

I like how KNC have a situation with Corsair PSU's and they ask a guy from GE!

Does anyone know any Corsair engineers? BTC whip-round and we fly him to Sweden tomorrow to join the "discussion"  Grin


The "guy from GE" is the VRM expert/engineer....I think he would know how to use an oscilloscope.

So, the GE engineer, I think, has shown conditions that can cause the blown capacitor.  If it is repeatable, then just changing that capacitor or one of the others in that row if blown, can allow the board to be used again for testing.  If the conditions genuinely can produce a repeatable fault, I would like the same test done but with a motherboard plugged into the motherboard connector.  This would show that the jumper isn't bypassing some voltage drain necessary for the supply to wake up properly.

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.

I haven't read any Billy Goat's Gruff arguments for HF in the last few pages. What gives?
Other than, obviously, that this is a completely inappropriate thread for it (but since that has mattered about 0 I figured I'd ask)

I totally second ElGabo and am very glad that you have a thick enough skin not to get pissed by so many fools bashing you here when all you do is provide us with excellent updates, tips, info, and your priceless perspective right from the beginning when you visited their facilities before they even started designing the mars prototype eons ago!

Thanks you from the heart! May you live long and prosper my friend Smiley

Order #40x, ordered and paid June 3rd... "Day 2"  Roll Eyes, 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. http://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 http://i.imgur.com/F386xnl.png

530gh/s+.. seems to be rising slowly! http://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 Smiley

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

did you make any changes to the cgminer.conf file?

Perhaps the api allow w:0/0 line?

or Perhaps the api port default 4028?

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.

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

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.
