I use 12.75 for block reward and 650 for coin price
Do you use 12.75 instead of 12.5 because you're counting on fees? yes we seem to do that on kano on average |

Really new to the whole concept of Bitcoin Mining, but we have very cheap electricity where I am (Approx 4cents/kwh). Can people take advantage of this if we setup a Mining Pool or something like that?  A lot depends on how much power you can provide. Also how good is your internet connection? Also where are you? USA a state is enough info. Not USA what is your country? 4 cent power is good. So pretend you have 3x 30 amp circuits of 240 volts. that is 90 amps . an s-9 is a modern miner it uses about 5.5 amps at 240 volts. so 4 miners is 22 amps a 30 amp circuit that is good since 24 amps is max to be used on a 30 amp circuit. you could do 12 miners safely 15 miners not so safe. so the 1 miner cost for a month at 4 cent is 40 usd for you you want some profit so 60 usd would mean you make 20 bucks a month on each one. that rate of 60 for an s-9 is very competitive with other hosters. Not sure you want to charge that low so 65 is 25 a month for each miner in your pocket. I do not count anything but power. no net costs no other costs. Plus people do not know who you are and will not want to send gear to you. Lastly these miners are really loud and really hot. So dealing with heat and noise will matter if you run 15 or more. |

Is it ever worth buying overpriced ones from eBay? The price direct from Bitmain is already overpriced; adding more on top of that is shooting yourself in the foot.
Sometimes, but certainly not now. Some ebayers get very good coupons I just got one for 8% it expired yesterday. this is 2200 - 8% coupon = 2024 and I can get 1% off via ebates so -22 = 2002 and I can get 6 months to pay it at 0 % so 2002 net cost and 6 months to pay with ebay protection and this was close to worth it yesterday. Coupon is gone so it is not worth it. But yesterday it was close to worth it for me. http://www.ebay.com/itm/AntMiner-S9-B2-12-93TH-s-Running-11-1-11-6-Underclocked-Stable-/172280227864? |

So Eth coin is on a solid rally. Market cap is big so big it is huge. Still BTC has a 79.38% share and ETH coin has about 9.06% So to put a true Hurt on BTC I would say ETH coin needs to get to 20-25% Opinions guess and thoughts are welcome. Lovers of ETH are welcome as are haters. Lovers of BTC are welcome as are haters. Fusionists (Loving both coins) are welcome Lastly Divisionists (Hating both coins are welcome) I self mod only to delete upon very rare occasions >>>>>>>>>>>>>>>Market Cap>>>>>Coin Price>>Actual coins 1 Bitcoin ------------$10,369,093,820---$ 657.42---15,772,332 2 Ethereum -------- $ 1,184,673,989---$ 14.40--- 82,240,471 Entire market cap = $13062570120  |

Can't wait to see it with cleaner cabling.
Yeah he needs these cables.  They are 3 foot long look like 16 gauge and have a nice wrap. All kidding aside a very nice build  |

Okay you got a r9 390 and low and behold you scored a hard to get rx 480. You want to run the cards on your rig. I am getting really good results. With amd 16.7.2 and with Claymore dual miner only eth coins. BTW eth is over 13 usd a coin up up and awayyyy!!! Give me time to set this up. I self mod but I almost never delete. so here is my mixed rig. 1 r9 390 with 1 rx 480 a gigabyte b75m mother board
2 4gb sticks of ram
a silverstone 700 watt titanium psu
a corsair case? Don't remember
case fans are silverstone 141's
cpu is intel i5 2500t got to check this as I can not remember since i have a few pc's this shows I am running around 56-58 mh with the two cards  power is from my 240 volt pdu reads 2.1 amps so 504 watts. I have overclock the r9 390 hard.  the rig is in the closer case  overclocked r9 390 and stock clock rx 480 (power limits at -28%)  So use amd 16.7.2 go to amd settings and click gaming  next click Global Settings  this brings up the r9 390 and the rx 480  |

Why the blocks are taking so long? (In the network I mean)
There are a lot,of s-5s and older gear being turned off. Before the 1/2 ing an s-5 at 6 cents power made money. Now after 1/2 ing all gear older then the s-7 or Avalon 6. Is losing money. So we have downward pressure on hash rate. There is close to 300-400 ph in old gear even if s-9 are coming on line a lot of old gear is shut down. Thus slower hash rate so with 3 cents power s5's are still viable? well here you go 1 s-5 at 3 cent power mining at kano pool. I assume 0 cost in that you paid it off already. I use 12.75 for block reward and 650 for coin price 1% for pool fees 2% for diff growth So it would be good for a while still.  |

It's advertising a server PSU and breakout board which is, overall, better than Bitmain's PSU. The conversion efficiency is a few percent lower but the total power, reliability, flexibility and price beat it.
If you're in the US and wanting to buy S7 from Bitmain, I can probably hook you up with undervolted units that run 85% hashrate at under 70% power versus stock units, with a power supply, for about the same price you can get just a new S7 shipped from Bitmain. This makes 'em more efficient than an S7-LN and can also be run on 120V.
I've read the post again.. Is the PSUs mentions DPS2000BB ? Also, why would we need the breakout board in addition to the PSU? I'm actually located in Southeast Asia, Thank you for the offer though  Based on your location and parts availability you are best off with bitmaintech. If you were USA based I would say go with the dps-2000 and set up that way. But your location means the bitmaintech psu is easier. Sidehack's modded s-7's and his power supply is also really good, but once again cross shipping China to usa to asia is an issue. Why do want s-7's do you have cheap power? |

After halving day, is mining with this machine is still profit?
I have 5 units S7, and my earning drop up to 75%, and a week ago I shut off 3 units
the s9 may work for you if you power cost is 5 to 8 cents per kwatt USD based money. If you are over 8 cents USD per kwatt maybe not. If you are at 12 cents USD per kwatt most likely a loser. See chart: S-9 a money maker or not. under 5 cents strong yes 5 to 8 cents maybe yes. 8 to 12 cents maybe no. over 12 cents strong no. Just an estimate nothing certain about my estimate. |

We are new to mining, but have been monitoring since Dec'15. We're prepared to purchase S7-LN as it came with power supply so it seems like a good purchase. However, S7-LN recently went out of stock.
We're looking to purchase S7s now and considering PSUs for our S7s. Should i get PSU from bitmain, or should i go with other PSUs like EVGA Supernova 1600?
first question do you have 220/240 volt power? you should not get bitmaintech or evga 1600 if you have 220/240 volt power read this thread far better to use this system to power s-7's and or s-9's https://bitcointalk.org/index.php?topic=1373092.0;allhttps://bitcointalk.org/index.php?topic=1373092.msg15403344#msg15403344 |

New gear is welcome. I would pick up a piece or two. I would also run a group buy like I did with the Avalon6

I just bought a desktop system with Radeon HD 5450 GPU Card
after installation of minergate software, it says no GPU available. so only CPU mining available.
i want to mine eth. or other cryptonotes with GPU Card.
i don't if the new Radeon HD 5450 i bought is not GPU or cannot mine with minergate or minergate disable GPU mining?
Help me figure it out.
What did you pay for this system? What is the CPU? What windows do you use? I will not tell you get a good gpu and mine eth coin with Claymore miner. Since I have not a clue how old and out of date the rest of the pc is. Right now just list the cpu The ram The windows the power supply The motherboard. We know the gpu is too weak to do this work. We do not know any other info. |

I am pushing 99 ? Is this normal? Worried. Its fairly well vented but could be better
I'd say its normal. Here's a screen from my S9:  During day time it pushes 107C. PS: I do have a dust-filter in the front, that restricts the airflow some. Edit: You can see that the hottest board is the one producing the most HW errors.. I would change freq to 593 . What is your fan setting? 85% manual? |

Another 999 S9's will soon join the network. I am so disappointed that they will be sold for cheaper, with a bonus AWS-1600 psu, and a 300 yuan coupon for future purchase. Anyone know if international buyers may receive similar benefit in the near future?
Links please Sales start at July 21 14:00 Beijing Time, which is in 2.5 hours from now. Shipping on their Friday this week. Did anyone outside China actually try to order one? If I had seen this sooner, I would have tried. it sold out so fast .... lame They are selling the gear far too cheap . I simply do not understand them they are giving the gear away. 999 units sold in under 12 hours . Phil... In many different contexts you referred to them as cheap. Just for clarification, I assume you are referring to cheap in terms of potential market demand but not ROI, correct? Roi is next to impossible if they sell tons of s-9s fast. There is zero need for an ASIC war as they are the only ones with guns so to speak. They are the only company with .1 watt miner. So they can sell slower . Selling 1000 units in 12 hours for 2.7 btc means they underpriced it in terms of demand. 1000 units in 36 hours at 3 btc is better for them. I'm convinced they will do what they think is best. For bitmaintech my plans as to what is best for bitmaintech mean nothing. I see a lot of moves they can make. They purchased block trail. A few other things were done. But 1000 s-9s are 13ph less then 1 % . Still they set a lower price floor on the s-9 for no reason that I can see. Here is the main address they use https://blockchain.info/address/1KwA4fS4uVuCNjCtMivE7m5ATbv93UZg8Vbut one interesting thing no large coins went here in the last 25 -30 hours looks like if there really were 1000 units sold they were sold via bank transfers. I wonder if it was posted up for 10-12 hours then listed sold out. When in fact nothing happened at all> chrome translation of the sale in china   |

While I can't decipher the Chineese web page, my simple view of it is that it is priced in CNY. In other words, the price is a fixed fiat price, and the BTC amount can "float". My recollection is that the English pages that used to be up for the S9 had a fixed BTC price. Unfortunately I can't confirm my memory since the English pages appear to be gone.
some were fiat some were btc chrome translation |

He probably meant 29 June
yeah he uses translations IIRC so maybe the translation ffff'd up |

As a Mets fan I should say no ,but your Yankees are not winning much so here goes.
........
hehe. finally got a series win on ya from the cubs:) tough team on us last few series. got a quick question. s7 what is good freq to go with .. its nasty today and next couple days here.. heat index of 110f. humidity if off the charts. im already pushing 70 c only on the center board and outer boards are a couple c less. running at 700mhz but from my tests at home it seems 600 would quit hashing after a while. Also same with 625. what is min i should go with and not have issues? Thanks on the diff.. looks like we seeing a drop.. hope thats not a precursor to the price;/. i was hoping to see a nice upswing but seems to be struggling.. eth is just blowing my mind how well its holding and rising.. coinbase just added it to the coinbase.com side. https://blog.coinbase.com/2016/07/21/coinbase-adds-support-for-ethereum/. Makes it easier on me.. although ive had a very pleasant experience with kraken. Nice to be verified at both anyway. edit> on the drop i see it aswell on the zeroblock app for iphone.. they used to have a website but its no longer.. only for android iphone now.> good feed for news too yesterday it was showing about 12 min avg block times.. today its showing 10 min.. i do believe its based of last 24 hours but im not 100% on that Best Regards d57heinz IF YOU have batch 9 or newer 650.0, 656.25 , 662.50, 668.75, 675.0 As for diff calcs yeah I have found a few inconsistencies here and there before the ½ ing but nothing major. @ Mikestang you have a good question as when I do real world real time numbers they are always close but don't quite match the sites. And I know I am consistent and my real time method is accurate. pretty simple 144 blocks per day is 0% so take the time expired from the diff to the current time. Example say 3 days so 3 x 144 = 432 so 420 made 432 = 0% 420/432-1 = 0.972222 -1 = -0.0277777 x 100 to convert to percent = -2.77777 % so if last diff was Jul 18 2016 213,492,501,108 0.04% 1,528,238,850 GH/s just x the numbers above to get an answer . so current diff would drop to 207,562,153,854 current hash would drop to 1,485,787,431 but those real time numbers I just gave are true from the start to the 3rd day I know bitcoinwisdom shows 3 hashrates : 504 blocks gray line which was wrong 1008 blocks blue line which looked okay 2016 blocks red line which is accurate since the blue and gray change a lot they are at multiple points in time and the chart does not show those times. |
