From initial testings with the slow ASICs we currently have, we see great over clocking potential in the SP20.
The limiting factor is cooling, and we're working to improve it. Experimenting with various enhancements to the heatsinks.
Convinced me to use my coupons and giftcard to pull the trigger on an sp20, finall cost was $364.94 not too shabby for 1.6TH i guess. Hope it delivers quicker than the sp30 did. |

Difficulty is up another ~15% in eight days , Not sure if it is worth it to invest in ANY new hardware at the current hardware prices . Even with a coupon and discounts a SP35 or 31 costs over 3k with shipping
ROI is looking somewhat impossible because by October when units ship difficulty could be up 30% from now ugh.
Don't worry. It will drop down to about 5-7% just few days before next difficulty change ;-) As always fine work with your charts and hardware predictions. You've saved a lot of investors more money and grief than you'll ever know. As you say "Pay it forward" I just want to say thank you again for paying it forward. Sarcasm I hope? The best investment I made this year is in gaw prime hashlets at $16/mhz Now I can sell them for $39.99 or possibly. My sp30 orders are a wash at best at worst no ROI |

If your going to do hosting with the SP20, why would you buy a 1.7Th/s when the SP10s 1.4Th/s are selling for $1,000 and below with power supply included on ebay?
How much power use on the s20 isn't it like 1200w? Its a tad more efficient I guess than the sp10 but you're right its not a great dea Should be priced closer to $900 P.s I guess the assumption is that the buyer already has a psu , |

Hmm how are you getting such low wattage ? your temps are higer than mine as well. my voltage hovers around 236/239 watts are 1350/1340 my Max voltage is .76 and start is at .66/.66 It seems different ASIC require diffrent amounts of power ? Other than that hash rate hovers around 4510 similar to yours but with a big higher power consumtion it seems. |

If I was a rich man and could put a decent wager behind a bet I have, I probably would rake in a nice profit..
I've started to believe the whole BitCoin world was taken over by Central Bankers long ago when they thought it might disrupt their banking cartel.
I seriously doubt that there's that much mining hardware coming online every 12 days that the difficulty jumps up anywhere from 7% to 20%.
That's bullshit!!
How's that happening?? NSA super computers being used to pump up the mining threshold??
I'm mining at 1.5THS and barely making $13 a day... 8 months ago I would have been making over $100 at that hashing power.. Talk about diminishing returns..
If I wanted to make $100 a day today, I'd have to be over 10THS, which I'd have to throw in another $20K in mining contracts. And that would only get up to $100 a day
for about 2 weeks before the fucking difficulty jumped up again..
And since BitCoin is tied to fiat currency, I'm guessing the reason it's down to $480 is because the fucking US dollar has somehow gained in value?!?!? Not in my opinion.. Try going to the grocery store and getting out of the store with 1/5th filled basket without blowing $100.
What happened to the idea that the more BitCoin was accepted by retailers that it would gain in value?? Not from what I'm seeing.. It should be up over $2000 a BTC..
And those of us who have invested tens of thousands in mining would actually be making some good money in return...
Lol you have just answered your question, those who raked in larg profits from mining ealy in the game i.e the BTC millionares , the KNC,s BITMAINs basically the whales instead of investing in the BTC ecosystem I.e creating stores and retail opportuninites centered around bitcoins choose to just dump more and more fiat into hardware for mining. then they turn around and dump those BTC they mine on the fiat market by the 100s a day why the hell would BTC rise ? Eventually if things don't change BTC could go to a point where no one can afford to mine anymore and either these whales will do the right thing and invest in the eco system or BTC will die. It could be that there are whales in the background working on some services and things like I have discussed in the background and release them in the next few months similar to what GAW did with hashlet. |

SP Tech has come through for me again :
I got my coupon and discount and they are now allowing us to use those coupons towards the SP20.
I might go that route instead of finalizing my order for an SP31 since it is basically a free miner and combined
with my SP30 that would give me a total hash rate of 6.3 TH which is above the promised spec of 6TH from our original orders.
**Note**
I really would prefer the SP31 but the sound and the heat might be a bit much for my basement with two of these monsters.
Thanks Guy and also Ms Greenberg for getting back to me.
now only thing left for me to decide is weather to complete the order for the sp31 now or get the pretty much free sp20 decisions decisions

So it's speculative BS just like before. Let us know when you have some real world numbers.
Not speculative at all. It's working piece of silicon with known and understood production tweak. Yeah at that price point even with my PSU's I have in hand the SP20 wont work for me especially since I can't use any previous discounts... So anyways about a week ago I placed an order for a sp31 and I was unable to apply any coupon code since I still have not recived one on the 5th I got this email from sales Barbara Greenberg (Spondoolies Tech)
Sep 05 16:35
Dear Ola,
We will issue your coupon Sunday. You will receive an e-mail with the coupon number to apply to your October SP31 purchase.
Regards,
Barbara
-------------------
Kind regards,
Spondoolies Tech Support
so its the 10th still no coupon and I cant complete my order still what gives ? |

any way to get refunds from Titans or not really? ;x
you find a way let me know will also consider an "ocean's 11" plan ....it may be the only way to get any btc back from knc now Searing lol in this case 'oceans' 14 we need brad pitt to get in on this |

Probably a world record for hashing density.  Looks like about 2 Petahash / second or about $500,000 / month at today's difficulty Really? Top shelves: 9 x 3 x 2 x 4.5TH = 243TH Middle shelves: 8 x 3 x 2 x 4.5TH = 216TH Bottom shelves: 8 x 3 x 2 x 4.5TH = 216TH Total = 675TH Its whales like this that ruin the echo system for everyone , I'm hoping they at least bought thier hardware with BTC however i sincerly doubt it |

Hmm so i,m sitting on 4 1300 watt gold rated power supplies from my previous scrypt mining operation which i parted out last month.
was tying to sell them on eBay but got tired of the stupid low ball offers. They all cost over $200 and no one seems to want to want to pay more than $100
so decided to hang on to them.
Now since I am waiting for a sp30 august batch coupon and with the release of the sp20 looming it , depending on the price with my PSU's sitting here it might be more cost effective for me to grab a bunch of sp20's since I already paid for all these PSU's.
any thoughts ?

Edit I'm pretty sure this post gets deleted in about 10 mins btw lol Reading this thread and all the whining here cracks me up. We as private miners are the cause of this rise of this monster called KNC. They used our greed against us and used Our freaking money to not only make it harder for us to mine but also now probably using all the infrastructure they build using YOUR money as collateral in order to secure MORE cash to even expand thier mining operations further ?!!! This is the true definition of the gift that keeps on giving. What fascinates me about this is that people actually gave them another $15million or so on Titan Preorders when we already know what they were about. At least Bitmain doesn't even pretend to care about selling hardware to private miners. I have the say KNC has pretty much won this fight after reading this last announcement , I think the only thing to do know is do all you can to boycott all their services , blogs and ignore them like people do Bitmain. I'ts hard to believe they could say this with a straight face. I can just imagine the raucous laughter that occurs in their meetings and strategy sessions when they discss this shit Mr. Cole declined to say whether this activity is profitable for customers. “We don’t give indications of returns. That would be bad for business. We are not a financial adviser. We cannot guarantee the performance they will get. The customer will have to do this,” Mr. Cole said.
The difference now, he said, is that given that customers get access to the mining equipment immediately, it “makes the math easier to do.”

I'd love to see some pictures of all your gear running. How many cages did you use for all 37 of them? How many can you shove in one rack? How's the temperature been stable since you have been adding lots of sultry hardware? Don't forget the ear protection. One of my co-workers worked in the head-end (that's what some cable companies call their computer rooms full of switches and gear) and never used ear protection. He lost about %40 of his hearing over time and didn't even notice until it was too late since it happened slowly. And there are signs all over the place warning to use ear protection. Derrrrr.
ok you are scaring me with this now, is the noise of one or two SP30's loud enough to cause hearing loss ? |

Ahummmm is this bad news ??

0: disabled (i2c BAD, btw!)
1: disabled (i2c BAD, btw!)...
A breaker might have tripped. It's also possible that one of your PSUs overheated and got stuck in the overheated state -- that happens on occasion too. If the PSU has a flashing orange LED going, then a full power cycle (unplug both PSUs, wait 30 seconds (this actually matters! Don't wait only 10 seconds, as that isn't enough), plug them back in) should fix it. If the LED is dark, then your PSU isn't getting powered, and you should check the cables and the circuit breakers.
Please everybody read the red part - important! Edit: I will change the configuration that we ship the miners to be 1300W by default. This way the clients will get the units running at safe rate, without failures, but it will take about 1%-2% of their maximum hash rate. After the client made sure the miner is working, and he has access to the miner for a few hours, he can increase it up to 1350W in settings page and let the system learn. seems alot more stable with the newest firmware |

My box keep rebooting as well its been up and down since the latest firmware
I see some people having this issue. It is related to systems that boot slowly, for example blocked NTP, and watchdog restarts them. I released version 2.3.40 that solved the issue to a client. Please try and see if it helps. I will get more into this issue tomorrow, write if it helped.Edit** spoke too soon, same issue still with the different PDU It wasn't the NTP issue on my end I have a CISCO PDU that seemed to be the issue my WU rate was also low in the 20s on my pool. Put the both PSU's on a different strip and it seems to be more stable. I did check the SSH with t hat command to test for NTP issues and that seems not to be it since I did not get the alarm. One thing I noticed on the previous PDU was wild voltage swings from 230-245 on the PSU's on the CISCO whereas the ADP holds both at 233-232 |

What are you guys's hashrate? My sp30 runs at around 4600 Ghps 24h average, is that below, above or precisely average?
That is wonderful, seems you have +5%  mine runs at the spec 4500 + or - 50GHZ i cant get it to use over 1355 watts though otherwise I could get it to run much higher, not sure why |

What is the big delay with the GB coupons?
Is this answered yet? Have anybody recieved a coupon? because i wait more than a week for the coupon it means we who choose compensation in form of coupon are at the end of the order que... All of the August customers who requested a coupon were sent one. We are now going over the September list. Gadi I did not get a coupon |

Yes, space in your panel (and therefore moving breakers around) can be an issue, but if you have space for sp30s available and decent power rates, getting some 220-240V circuits installed should be pretty straight-forward.
Hosting at home does help the most with decentralizing the network, but it might prove a little difficult to run more than one sp30 at home (although noise levels are much better than the sp10).
With the colder months approaching (atleast on the northern hemisphere), heat shouldn´t be as much an issue and some fans and an open window can work wonders.
I dont know about the noise being lower it sounds like a leafblower , I'm going to need to do some sort of sound proofing or silent cabinet. Running two would be an insane amount of noise. |
