To the SP20 owners. Question - Are you happy with it? Any objections? Given current difficulty? BTC yield? Are you in it mainly for the hobbyist factor VS going a mini farm?
Its great. If you want to replace 3x Antminer S3 with one of the SP20 . Less space, more noise. less power supplies. However , You probably newer can not be achieved speed 1700GH/s at a normal temperature. I succeeded this only with software 2.4.22 TEST VERSIOON (i it is no longer to manual download.) Current firmware version: 2.5.27 give me a stable Mining Rate: at 1650 Gh/s and up SP20 Temp Front / Back T,B 15 °C / 66,68 °C SP20E Temp Front / Back T,B 16 °C / 74,69 °C SP20E Temp Front / Back T,B 15 °C / 65,66 °C |

Remember that if you're overclocking you [officially] lose your warranty, and I personally wouldn't go up more than 1 voltage step on the stock PSU.
R ecentlyYou Dogie wrote a different story. November 25, 2014, 05:56:52 AM You wrote RMA time. , if antminer S4 has not worked as a frequency 218,75 and bitmain only wrote S4 sales page * Hash Rate: 2,000GH/s guaranteed * Power Efficiency: 0.69Watt/GH/s at the wall * Over clocking: About 10%, but not guaranteed Not one word of lose your warranty, with overclocking . Can you explain this?For Dogie, regarding my issue, I have power cycled, rebooted, checked connections, reset to defaults, reloaded firmware,, and still cant seem to get these chips to pop up,,  out of the 11 that we have this is the only issue. we have 9 more on the way, should get them today! |

SP-T, can you tell me the measurement of the heat sinks on your SP-20? as well as the distance between 2 mounting holes of the heat sink?
I'm working to make waterblocks for SP20
Why reinvent the bicycle ? Spondoolies-Tech have already made watercooled SP2x miner. I've seen the software for it. |

Has anyone tried the 100 or 125 MHz clock settings provided by Bitmain? I'm just looking for feedback if everything is working properly, and if the power from the wall is as advertised? Is there any risk from underclocking?
...
Yes. 0650 125M 700W 1160GH/s There is still too expensive and too big from underclocking. I prefer underclocked SP20 |

why did you open a dispute? Did they replace the "first" one? if so why would you open dispute on the second one? Not sure of your situation just trying to figure out why would possibly damage syscoolings paypal status doing a chargeback.
My first pump was D.O.A. and they did not send me a new pump, although promised. And I'm ready to destroy them, any status as PayPal, as well as here. I paid them a total of 3x -$172.40 USD |

Please follow the following instructions in the same way you followed them last time:
1) ssh into the unit
2) echo SP2x > /model_id; echo SP20 > /model_name;
3) Do FW upgrade using Web
It worked. Now I have 2x SP20E Jackson Thanks |

I was not talking about any adapters. I was talking about replacing the fans with more efficient units. Anyone who would put something between the fan and unit is a dumbass.
works for me S3 without adapters Temp 41 , 37 Fan1 2,100 Fan2 1,920 S3 with adapters Temp 41, 46 Fan1 1,320 Fan2 1,080 |

Don't type the word "type" and don't put quotes around it either. At the command prompt just put: echo SP2x > /model_id; echo SP20 > /model_name; Too complicated for me. Does the model name must be model_name Does the model id must be miner-FL1448081742 or model_id I'm better waiting for the software to correct this mistake. One SP20 does not work at all, and the second miner Mining Rate: 1727.35Ghs which is great result. |

I have a feeling i'm the other guy. It is syscooling I'm waiting for. Over 3 weeks and no RMA parts. They are flat out horrible.
Bitmain is a different company. Email them they have good support and have always treated me fair.
Yesterday stopped working on my second syscooling pump. Fortunately, I paid via PayPal. I opened dispute today. |

Shipping 70kg Antminers to Poland is too expensive for me.
For 0.45 BTC I get they simply sold at the local market.
None of us not buy anymore S3 from bitmaintech. 2x antminer S3+ with shipping to my country costs today 1.495 BTC ( 563.37 USD ) +20%VAT

Hi guys, I used to mine btc a couple years back with my radeon cards, but that got old quick, so I decided to take a plunge for the back Friday sales. I decided to pick this baby up "BitCrane T-110S 1 Th/s Ultra-Silent BitCoin Mining System" So it does 1Th/s. How long would it take to mine 1 single BTC (in a decent pool, I need some help with this though, can somoene point me in the right direction with a good pool? Thanks!)? Im basically just looking for some basic info about it, as I've been out of the business for a while... Thanks fellas! And also, did I make a good purchase or was this a stupid waste? haha  This train is long gone. Do not buy it. Buy Better http://www.spondoolies-tech.com/products/sp20-jackson-november-batch-2Warning. It's not quiet. |

The 'sale' is actually a very fair price to medium-level and larger buyers.
You can use 1 coupon ($400) per 16-pack. That makes the final price (shipping included) $12,688 - or $397/TH. Thats cheaper than 16 units purchased individually with coupons, particularly considering that the price includes about $2000 discount on shipping costs you would otherwise pay. Thats about 1BTC/TH WITH PSUs DELIVERED.
in contrast, the SP20 deal works out to around $415/TH and does not include power supplies (another $40-70/TH) and do not rack-mount.
noone includes the custom fees in their price - every customer pays different fees depending on country and personal/business use.
IMO, would love to see a 4-pack/$3400 (shipping included) option for the smaller miners.
A much better deal is 15x SP20 Cyber Monday Special Price: SP20 Mini Farm Batch 1 $10,425.00 +free shipping. $695 per miner. You can easily underclock/undervolt SP20 to 0.55w/GH to extend the lifespan and you are still 1200GH/s miner. You will not be able to do this with Antminer S4, S3 or even C1 SP20 be more expensive, but much longer lifetime for mining. The most important. If you buy the SP20, then get a new miner, not "2 months tested" miner. |
