Just got mine today, thanks for the warning. It took over five minutes to start hashing after a reboot with my pool settings.
Yep the panel settings have been changed as noted above. But hashing at 11.6 ish.

Hi miners & community,
We are ready to launch our second data center project facility in 3-4 months period from today... we already have our second property in South America. Our current data center facility setup is 15 megawatts of free energy partnership program. Our new setup will be 10 megawatts in the first stage and by the end of 2018 additional 15 megawatt project to be finish.
Program details: Miner 2.0
1. 50% partnership
2. Zero electricity cost
3. Miners must send a minimum of 26,000kw of equipment with power supply. Equipment: S7 or S9
4. Equipment will be divided 50% to customer's account and 50% to NAMSTEC account.
5. Contract agreement
We can have live chats on our current facility with miners, investors, equipment manufacturers and community.
If you have any questions feel free to contact me.
Thank you,
Andres
NAMSTEC
Skype: namstec

Can you post some pictures of your first data center? Also some photos of the new one (second one under construction) would be great too. Thanks! |

This is what I sent to Bitmain just know but hoping someone can help me before them. I just recieved my S9 about 36 hours ago. I connect and hook it up like all my other miners before. I have had about 25 different Antminers. It took a bit to coneect to the network, I had to use different wires but it eventually connect, it ran for about 6 hours and stopped hashing, but stayed powered on. Now I cant get it back on my network with my other machines. I have reset my router and switches. I have tried to reset the miner by the button on the front and nothing works. The mach powers up and seemed to be working fine but it wont connect to the network nor will cgminer start. I have attached a YouTube video, I removed the front plate but have not disassembled the miner at all. I need to know what needs to be done. Do I need a new controller? https://www.youtube.com/watch?v=mPBOCCsmc2kI will tip anyone that can help me. Thanks One of my S9's had the same issue. It was the BB board (black board on top of the controller with the network connector) that had to be replaced. Bitmain warranty asked me to swap it out with one from a working miner to trouble shoot (verify) the problem. Once I verified the problem I filled out a warrenty repair ticket and sent it back to Bitmain and they sent me a new one. Took about two weeks total to get it up and running again. You will have to pay shipping one way and they will pay return shipping. FedEx was cheaper than UPS to China ($80.00). Let me know if you need anymore info. Good luck! |

Let's look at some numbers here. Please let me know if you calculate them with different results.
1.) Electrical cost going forward: $80 per miner * 30 miners = $2400 per month
2.) Rental cost of power supplies: $5 per miner * 16 miners = $80 per month
Total monthly cost: $2480
Total monthly Btc: $4160 (from your previous post)
--------------------------------
Total monthly income: $1680 (difference from above)
Six months income: $1680 * 6 = $10,080
Six months (July 10th to January 10th), I'm assuming the difficulty would have increased significantly by then.
1.) That's also assuming all miners are up and running at 100% all the time. With the heat coming this summer in eastern Washington I would expect some downtime and possibly lose some miners to overheating.
2.) Again you would need to calculate the difficulty increase. 5%...10%....20% over six month? 10% would knock approximately $1000 off the six months total income.
3.) What will be the resale value of the S7's and power supplies when the contract is over (~2017)?
Let me know what ya think?
Are you open to offers?
Thanks much

Very good Analysis. 1) I have already been with this collocation company and have avoided loss of equipment due to running (1 was a DOA). I did have some under clocking from the temps over 100 degrees, but have been compensated for that time. 2) Yes there will be difficulty increases, but to compensate and possibly full negate this would be the increase in bitcoin over the next six months and longer. Last year August bitcoin was setting at $228... 3) PSUs don't really loose their value. They can be used again and again. If you take a look at the S5s on eBay they are still selling for 1/4 of their original cost. People still buy S4s, S5s, S7s...Resale will still be there, especially under $500. I believe that if I hold these miners for the next six months or a year, They can still turn a profit either with their Hashing or their asset value. I am always open to business opportunities. Thanks! I agree that the btc price 'could' (and probably will) increase in the coming months. Depends mostly on the Chinese currency controls and Yuan devaluation, but everything points in that direction. But: 1.) I just looked up the difficulty increases on https://bitcoinwisdom.com/bitcoin/difficulty for the last nine months and it has more than doubled (over 100% increase) from 1.0e+11 to 2.0e+11. That was a huge under estimate on my part. So first approximation (50% increase in difficulty) of the six month return should be: $10,080 / 2 = $5,040 (just a guesstimate). 2.) Resale value of the miners will drop quickly. I've been selling my S5's and SP20's for $50 each on eBay and lucky to get it. I did get $144 for an S4 though. I'm assuming I'll be selling S7's for the same $50 in six months. Once the S11's come out, both the S9's and S7's will drop quickly in resale value. Thirty S7's * $50 = $1,500 With no increase in difficulty $10,080 + $1,500 = $11,580 With 50% increase in difficulty $5,040 + $1,500 = $6,540 Not sure what a reasonable offer is at this point? Thanks much --TW |

Where can I buy silver/gold with BTC? I'm to lazy to search for sites and most sites seem to have a 1-2 week delivery delay? Is there any site that doesn't have such a great delay. The site must also be trustworthy of course  maybe you should try bitgold, I never bitcoin deposits there, and pretty quickly, but I've never bought a silver or gold, and I do not know whether the shipment is late or not  FYI bitgold.com is gold only (not silver). Silver takes up too much storage space and thus not cost effective for them. I highly recommend them though, it's run by a huge online storage site called goldmoney.com (both gold and silver storage). Look up "James Turk" and listen to some of his interviews fist, then make your own decision. Online website and iPhone app make it super easy. |

are there other miners who got scammed or have burned miners at asicspace, i am be trying to get (as they say) my broken miner.
I am asking them sent it back for 5 months now.
Every time a diffrent story why they don't sent.
Trying to set up a lawsuit, looking for more people that have experience with this.
I've got some Sp20's, S5's and a S4 running there and I'm happy so far. They are very responsive to questions and will do a hard restart of a miner if needed. The dashboard feature is good and has only had one small/short outage that did not affect the hashing (just remote access). Once I notified them it was quickly fixed. FYI I live in Washington and drive there to deliver and pick up miners so they don't have to waste time and cost with shipping. That works out well for me. But I'll make sure during summer to have tempature settings on and may under clock them if needed to keep them from overheating. That's not a problem now with external (outside) temps in the teens (16F). I'll keep posting as I slowly build out my mining empire there. 😀 Thanks much |

Back to the miner itself, can anyone tell me if they see a pcie plug-in anywere on those three boards (pictured on the Sfards site)? None on those 3 boards, but probably on the backplane (not particularly pictured)? Look at the bottom two 'connectors' - they're just solid, wide traces to the power management board. here we go: http://www.bitstellar.com/steps( some broken images at this time - probably fixed soon - top one shows power connection end anyway ) Thanks! :-) |

Site says ：12V DC，6 PCIE Cables of 6 Pin are needed. http://www.sfards.com/pro/minerIt shows the boards pulled out (scroll down), but I don't see the usual white pcie plugs. I'm expecting to see two on each board. Am I missing something? |

Let me get this straight.....you live in Seattle (or at least had it delivered to Seattle usa), but paid for it in Euros? (600 Euro) When I go to the site it was $649 usd for the S4+ and I'm looking at the site from Seattle.
Otherwise maybe it's some kind of promo for the site? Not sure,if so you got great deal! :-)

Hey, isn't this about the same as an SP20? (the BTC only side). Should I be disappointed now with the 1.7TH/s performance like I am with my SP20? Or pay a whole bunch of money and then be disappointed? Just asking.
SFARDS
Bitcoin single mining mode:
Hashing power 1700 GHS, power consumption 770W
Spondoolies SP20
1.7 TH/s ± 10%
The SP20, if it could do 1.7 TH/s [Not all can] would use almost twice the wattage as the SF100. That's if you are just looking at the wattage on the BTC side of the SF100. Thanks! And this part: Litecoin hashing power 47 MHS...power consumption at wall of whole miner is 960W. FYI... Nicehash pays this for Scrypt. Can someone help me with the math for Scrypt (GH to MH)? Is it even worth it? Scrypt 0.3073 * * - BTC/GH/Day |

I would join a group by depending on price per unit.
Same here! I agree with the Dr. Probably one or two units for me depending on the price. |

Can someone who knows their electricity tell me what type of panel this is?  "tell me what type of panel this is?".... A damn nice one! :-) |

xfxforce.com site says: "Fixed Peripheral : up to 7" then "Fixed 6-pin PCI-E : 2" Anyway, this should be fine for powering a single S5. |

Probably best to lower the wattage setting to 180-ish Max Watts (at least for that loop). 120-125 is the overheating area.
As per philipma1957 page:
Temp Front / Back T,B
33 °C / 72,67 °C
Fan Speed
40
Start Voltage
0.62 / 0.62 / 0.62 / 0.62
Max Voltage
0.67
Max Watts
180 / 180 / 180 / 180

I’ve had one S3+ where a PCI-e connector started to turn brown with very mild over-clocking. So I changed the clocking and switched to the other PCI-e connector that was still good (on that side). Once I saw that I decided to under-clock all of my S3+’s from there on out to maintain resale value.
Thanks goodness by then the S5 had come out and I started switching over and selling all my S3’s on eBay. I’m running all of my S5’s at the stock clock rates and have not had any problems.
You should be able to get a used S3 on eBay for the $75 to $100 range?

If you really want a Spondoolies SP20 I will sell one of mine for $500 USD or 2.25 BTC (plus shipping). Just putting that out there :-)
Thanks much! have a great day.
