just stopped in to say...    'if you would of just bought BTC instead of ...  blah blah'  

anyone want mark down all the coins they could of sold at 1100+ ??  


.. as you were

You mean the ones I sold at 1200? Buying time is coming up soon

I'm mourning a dead Blade today, my one and only.  It's come up with all xxxxxxxxxxxxxxxx for the ASICs.  We had a warm December day in Georgia, 71.6°F out and 76.0°F in the room.

I couldn't bring myself to buy a Neptune.  Just too much for me.  That the Neptunes aren't sold out yet tempts me right now.  But no.  Ah, the falling BTC harvest, now accelerated losing 10GH/s.  It's like aging.

That sucks... 76* killing it ? Is it a really oooold blade?

Anyone else have a die that shows up as "off" in BertMod?



With SPI voltage at 3.3v, I've tried adjusting the individual die voltage from the lowest to the highest without effect.

Is there any benefit to bertmod if your KNC equipment is hashing well above spec'd rate?

Lots of snow falling here, still no problems with the Jupiter. Eligius 12hr hashrate avg is steadily climbing, currently at 650gh.  Someone asked if there was a difference case on or off. I saw no hash rate difference with either, so right now the case is on to keep it looking good.

Guys replacing heatsinks, is there a better than stock replacement out there if we run into issues in the future overclocking them? I think the current heatsinks are pretty good.

HAHAHA!

Sure glad I invested in hardware instead.  Right?

So received my Nov Jupiter.

Can't connect to machine by either SSH or webpage.  It is assigned an IP address just can't connect. Even ping gets no response but not sure if the BBB is setup to respond to ping.

If I disconnect all 4 ASIC boards I can connect to the host and access web gui with no issues.  
Reconnect the ASIC boards, can't connect.  
Tried connecting just one ASIC board with same results.
Tried two different power supplies with the same results.

Anyone had anything like this or am I just SOL?

That is an odd one.

You might try reflashing the November firmware onto it.  Maybe you got one with October firmware on it by accident and that's causing it to hang during boot?

[DPoS]

Anyone else seeing 630gh on the new Jupiters? Some readings on the first module seem off.

they went back to an 8 VRM design...  epic lulz...  (we don't need no sticking 8 since we aint got enough of the early ones and rigged it with 4)

hno on IRC said that bertmod is not expected to work correctly with the November batch, in particular reading the DCDC data.

Maybe silly question but you didn't flash 0.99-tune onto it did you?

If not...

I'd get the RMA email done right away, you can always cancel it if you fix it, but at least get the ball rolling as it can take a day or two, then I'd go on the IRC channel and ask hno what he thinks

It's probably reading it correctly. KNC said I may be able to correct it when the tuning firmware is released.

Got a November Jupiter yesterday with absolutely no thermal compound on any of the chips.  Just shiny metal on shiny metal. Be sure to check before powering up.

Well at least they removed the plastic cover from the heatsink this time.  Progress!

Now I understand your agressive inverse trolling recently.
(engage a troll and 'you are what you resent')

I wonder if you got the unit pheonix 'twisted' the cooler on.
Remember that amazing 'fix' ?

yeah, with like half a gram of twist... and yes, it is the "finicky" board I had... (never noticed anything strange with heatsinks)  "Amazing" is totally not anywhere close to what was said....and by the way... He knows that, and it was priced accordingly, and sold separate if you must know..... He asked to purchase it knowing so, and was priced accordingly....   with the addition of a free six-port controller, and beaglebone... (which is an entire Mercury) but not like we asked you to be judge, jury and executioner .. especially without knowing the facts. I could have easily RMA'd the board, and had a mercury to sell for xx$?(Not like you could know we actually communicate, and Cypher is a really cool guy) But, trolls will be trolls, however "inverse" they deem others. It looks like every time I comment in here, I'm sticking my head out on the chopping block for idiots to attempt at swinging an axe. I've literally helped dozens of people in here in one way or another,(not talking about sales either) and have always been a straight shooter...  endless teamviewer sessions, skype calls, and up all hours of the day and night for the past two months, on top of my regular jobs.  I'd even like to think this may have even contributed to the boards coming my way. Why? I enjoy helping people. When it becomes not enjoyable anymore, I will cease to help in here. It is coming ridiculously close to that. I'm really glad the units are getting larger & more expensive for that reason alone. Everyone who has dealt with me has been really cool. I consider each and every one of them friends in one way or another. Dealing with this trolling rhetoric of accusations and innuendo's is non-productive, however it may make you feel better, there's actually a person on the other end here, getting alot of hassle for what? Of course, I'm not always right.. I'm human. So are you.... which is why I even bothered interjecting to set the record straight . I hope that clears things up a bit. ...Clear as mud...I know... lol

Does anyone know what the typical support e-mail reply time is nowadays?  I had a nice fireworks display on one of my Oct. Jupiter's when upgrading PSUs and haven't heard anything from them for a couple of days now aside from the auto reply. Just curious how long it will take to issue RMA.

What the bloody did you do? All you have to do is swap cables.

And that is precisely what i did.  I was going from a Coolermaster v1000 to a nice Corsair AX1200 gold.  Brand new out of the box never used, plug it all in, hit the switch and poof.......Fire!  That was my good Jupiter too.

Here is the aftermath.
https://i.imgur.com/pcK68po.jpg[/img]

For this reason I think the plugs having both a jumper and a power resistor to the 3v line are a very good bet.  I know you followed instructions, but did you put in the jumper then fire up the supply and check that the voltage was there on the 12V, then shut down the supply, plug the power supply into the Jupiter, then switch on the supply?

If my theory that the current ramp, preventing current surge producing a voltage spike sufficient to blow the caps, the current ramp to ramp up current on the 12V line is actually controlled by a voltage ramp of 0 to 1V produced on the 3.3V line (because the 3.3V will be up to regulated voltage before the 5V or 12V) then putting in the jumper, turning on the supply to check if the jumper is correct and voltage being supplied, then shut down before plugging into Jupiter, since the supply expects that it is plugged into a motherboard having a load on the 3.3V line, it expects that when the supply is turned off the 3.3V line filter capacitors will drain out thru the motherboard.  That can't happen without a motherboard or a resistor to ground from the 3.3V line as well as the jumper.  

So, if  you check the jumper was correctly placed by looking for 12V on the 12V line, then shut down, plugged the supply into the Jupiter, and turned it on, the supply 3.3V line never drained and still had full voltage on its filter caps and the timed ramp voltage that controlled the ramp for the 12v current had remained at max, as if already having timed out its ramp, and BANG, instant max current.

Actually I did not turn the unit on prior to hooking it up to the Jupiter.  I did check that the pinout was correct before starting though.  There should have been not been any voltage on any lines prior to this fault, so I am truly baffled how it could get so much current.

Going forward though I would consider a resistor on the 3.3V line, just to be paranoid.  What resistance would be sufficient do you think?

Mate you seem like a chilled out guy, maintain the composure, the negatives are just after attention nothing more, either ignore them manually or use the tools at your disposal. Or if you want to keep an eye on them and just give an opposing opinion then do so in the spirit of the debate, don't stoop to their level and make it or take it personal.

The people who you helped know what you are about, and the people who take what you do and say in the right spirit also get you.

This is an internet forum full of keyboard warriors just like any other internet forum, and they have formed factions just like Ati/Nvidia or Mac/Win or AMD/Intel or Amiga/Atari or SB/GUS or whatever other MCIBTYC ego boosting attention grabbing crap they want to come up with.

Maybe take a rest, for the weekend. Its also probably harder for you to maintain interest now that you don't have any miners to play with. Stay away for a couple of days, of course they will say that you are doing it because you are ashamed or afraid or some such balls, but who cares.

Honestly, I'm not sure...  They released the Neptune for general public much sooner than I guessed they would, which is why I panicked thinking they would sell out faster than the others...... I tried to notify everyone, but my posts in here were being deleted by a mod within like 30 seconds! (off-topic)so I attempted PMing everyone that was interested....   He was just fast & ready before I had a chance to complete PMing everyone ...I was eager and in a weak moment wanting "Neptune Bliss".....  I apologize for any inconvenience.

Do November Jupiters have a user configurable turbo mode, and if so what sped does it reach ?

No inconvenience, I just know you and I had talked in PM, but it wasn't about a Jupiter which was slightly flawed. I would've taken a deal on a slightly flawed one haha. Just curious.

Cheers to all.

No, I received this response when asking about the tuning suite and turbo mode for November units:

Hi,

Apologies for the delay in reply. There will be an update to the November firmware to include the tuning suite. Regarding the turbo mode, it is enabled as default with the November miners. The option to enable to disable it was removed.

It would be great if KNC enabled php on the BB, that way they could add the miner.php file and add an additional tab to get lots of cool info!

So how can one prevent this from happening?
Shut down the PSU from the switch at the back, unplug from the socket and then remove and insert the jumper a couple of times to discharge everything?
