Anyone have any problems running the Nov. jupiters from EVGA G2 1300w? I had 2 shut off last night for no discernible reason, except that they both use the same EVGA psu. I have 4 other jupiters using the same PSU... so don't understand.

How good do you need to be with tech stuff to get the Neptune up and running? Also, I saw an article about the neptune bringing in up to 2,1 coins a day, can that really be anywhere close to what it'll get?

http://www.ibtimes.co.uk/articles/529324/20131211/bitcoin-mining-rig-neptune-kncminer-daily-earnings.htm

Wow. What a devious dishonest statement to make.
No, you wont get anywhere close to that number. What that "spokesperson" forgot to tell you is that the amount of coins you mine is utterly dependant on how fast the rest of the network is. See if you can spot a trend:

http://bitcoin.sipa.be/

If the network doubles in speed (which currently happens every month), your mining revenue for a given machine is cut in half. Neptune most likely wont ship before June 2014 (thats my guess anyway), so it wont mine a dime this Christmas and it will not mine a fraction of the numbers quoted next Christmas.

Shame on you KnC (or IB times if he was misquoted).

That was a complete misquote. I was fired a load of questions via Skype. The guy wanted to know what Jupiter will make currently, and what Neptune will make when it is released. The guy appeared keen to learn, but knew nothing. So I explained the entire concept of mining and respective difficulty rating and how future coin price and competition was impossible to predict. I said the only thing we have to go upon is today's current difficulty. I said that a Jupiter from October makes between 0.3, and 0.4 coins (remaining in the shy side, and that the November one is a little more powerful. Then said the Neptune will be around 5-6 times faster, but due to the fact difficulty will rise, it would take a diff of 3 billion + for Neptune to make what Jupiter currently does.

I gave him links to calculators, and explained he marketing scam behind the Genesis Block to propagate fear, uncertainty and doubt by continuously compound the difficult to freak people out and ensure a large volume of backlinks to their site. I showed the static diff calls that break the daily rewards down at today's difficulty and again arp firmed that difficulty rises each time a quantity if blocks are sold and as more hardware is added to the network, so he machine has to be more powerful to compete.

The above is literally a synopsis. I taught him the entire schebang about mining, and he basically took Jupiter today and multiplied by six, and then said something along the lines about 'ideal conditions'.

This was naughty, he was even attributing all these stats to me, so I contacted Business insider about this (where the chap was from), and the original article was amended straight away last week (go have a look). IB times have just taken the article and respun it as theirs.

Also i blatantly did not say 50 coins perblock currently. I said 25 and explained the process of the reward halving starting from 50.

I'm the one who posted that link and I appreciate you explaining it.

Do you have a real estimation how many coins it will mine?
[\quote]


Between nothing, and something. Wink

Honestly no idea what the difficulty will be like, no crystal ball, and will not be held down to any such figure.

That is precisely what I said I have that in writing on the thread in Skype.

I also said we are engineers, not marketers just prior, so I was very annoyed to see any such in print attributed to me!

PSU Quality might be variable, I had a brand new G2 1300 and it popped the moment I turned on the Nov Jupiter, getting it RMA'd now, replaced it with my Silverstone 1500W backup and it didn't skip a beat. Nearly shat myself though, it really popped loud, thought I'd blown a capacitor in the Jupiter, but its been fine.

Hi Orama,

there are post here stating the number of Neptune's left till sold out. eg. 178 and 108 left

is this accurate or would these figures be including orders that have been place but not/never paid?

As a heads up BitMinter is smaller but still large enough to solve a block every couple hours.  It has no required fee only a donation, and it offers perks for those who donate.  The pool also includes all tx fees, and merge mines NMC.  I have been mining it for two days and it has been solid.  One thing I never really thought about is BitMinter announced that to date they have paid out 1,000 BTC in transaction fees alone.  That almost a cool million USD in current exchange rate.  Many pools just keep the tx fees so it would be easy for BitMinter to make a million bucks more by keeping the fees but they don't (and never have).
Not quite correct. Prior to April 20th that would have been right, but from April 20/2013 onwards there is a 1% fee on mining income. Any donations are on top of that.

Is it one of the recalled EVGA PSUs or is it a newer one?  I think the cutoff was October.

What's with this another pre-order crap?!
We have all (first batch buyers) helped KnC startup with their business and it is now up and running like a train.
Now they treat their customers like shit and put up another pre-order BS!

And the big question is when are they going to deliver the Neptune?
They say Q1/Q2. Looking back to their original promise "before September" and then "all payed order before 15th of October", which obviously they have never made it.
Maybe when lucky the first unit will be shipped at end of June 2014?

I just hate people who can't keep their words! Angry
Anyway, couldn't be worse than BFL....  Roll Eyes

And as a reward, we all got a 3000 dollar discount on Neptunes...!  (the first 1200 were for us!)
I saved 9 grand on that deal.
I consider that alone a hefty reward!
Yes, each delivery batch was a few days late, but like close to 50% over spec on performance from our purchase date.
Not a bad trade-off, eh?
Imagine the ASIC race like the Kentucky Derby...
Your horse may have been slower out the starting gate than predicted... but...
He was faster than the rest, and won the race running twice as fast as predicted...... by a mile...
Do we shoot him anyway?    Would you bet on him again?
I'm betting the trainer of that particular horse works on the gate launching, and improves.  Cool


A wild fanboy appears. Can I get a copy of the script you're reading from.

Want to know why previous customers got a discount? Because KNC knew there was a good chance these people had the coin to pay ASAP, and around and around we go.

No, I'm using those as well and not really having issues. Can you check the voltage on your molex connectors? All of mine are showing 7v where it should be 5v.  That shouldn't cause a problem, but I'm wondering if I got a bad batch or something. The atx plug has 5v in the correct pins, and I'm not sure why I'm seeing 7v from all of the sata modular plugs. I had one Jupiter that wouldn't restart cg miner from the web interface or ssh and was acting a little strange. Still hashing fine, I just couldn't switch pools! I did a reflash by micro sd card and that's when I noticed the voltage. I only checked the output on the atx connector when testing the psus, because they SHOULD be on the same rails.

Errr, 7V is the difference between 5V and 12V, so if you miscount the pins and measure between the wrong ones.......

Just a guess  Grin

I have one EVGA 1300W too and no problems, but you might want to RMA your PSU. Check http://eu.evga.com/articles/00803/

iCEBREAKER is a troll! He and cypherdoc helped HashFast scam 50 Million $ from its customers !

merv77

I was under the impression they all sold out yesterday. I'm still in Vegas, and burying my head right now. I have had hardly any sleep these days, been on the go 24/7, and had to do a lot of talking. Looks like I've picked up a nasty chest infection, so I'm heading back to Europe tomo, but I won't be useful to anyone until I feel a lot better than this. Undecided

:boom:

Seems to be a common failure.  Anyone know the specs on those caps?  Should be pretty easy to change if one knew what to order as a replacement.

It looks like ordinary bulk capacitors (KNC's derating policy is very optimistic - if you could blow them up with a bit over-voltage).
I do not believe the capacity is critical (if they are bulks), just be sure to use 25V volt rating (or higher) so they don't blow up again.

I have two Nov. Jupiters both using the EVGA G2 1300w power supply, and have had one random shutdown thus far. I have no idea why it occurred, but moved some power supply cables around just in case that had something to do with it.

Another thing - Wish KNC had Saturday delivery available/readily offered. I know it's an extra 15$ for UPS Saturday Delivery, but 2 days of extra hashing is definitely worth it.
