This pool had amazing luck. Since understanding how luck works much better after this thread, I'll say the luck was great and I look forward to saying such again in the future, but no matter how hard I wish upon a star I cannot predict it  Simple n00b question for you guys. What is the best way to determine a price for your miner when renting? I read many threads discussing setting the price, and I have not seen a post by someone who said 'use this formula' or 'this website does it like this'. I understand the power usage amount, the estimated amount say 1 TH mines per day, and how it correlates to difficulty. Is there a more dynamic method with other variables? I don't mean a calculator to know how much 1 TH will mine, but a calculator which uses that as a variable, the power as a variable, even maintenance, downtime, Bitcoin difficulty, even pool difficulty. Maybe I am going to far for my initial question, but any input is appreciated. TY!! I am going to link you to another pool https://www.f2pool.com/help it shows its payout rate per th right now it is 0.0116977 btc a th daily this is the current rate - 4% ……. if you are renting your gear you want 25% more for your gear. If you want to rent gear you want to pay exactly number give or take 5%. quick easy to know. |

willing to share my winnings if someone willing to unplug 40 ph/s for a couple days. kthxbai
We had a decreasing difficulty last time and now we will just return to the last difficulty. close enough to true. btw if we see-saw for a few months time up and down 5% with stable btc at 225 or so it does not kill my setup price wise. |

found a nice chart 144 = 0% http://btc.blockr.io/chartsJan 28 --------163 Jan 13 ------- 124 Jan 29 --------165 Jan 14 ------- 152 Jan 30 --------142 Jan 15 ------- 141 Jan 31 --------162 Jan 16 ------- 145 Feb 1 ------- 156 Jan 17 ------- 136 Feb 2 -------- 154 Jan 18 ------- 157 Feb 3 -------- 133 Jan 19 ------- 141 Feb 4 -------- 158 Jan 20 ------- 122 Feb 5 -------- 159 Jan 21 ------- 146 Feb 6 -------- 171 Jan 22 ------- 138 Feb 7 -------- 162 Jan 23 ------- 121 Feb 8 -------- Jan 24 ------- 129 Feb 9 -------- Jan 25 ------- 124 Feb 10 ------- Jan 26 ------- 129 As you can see every day has been over 144 but Jan31st Last adjustment 4 days over 144 10 under note blocks made on feb 3 nice drop. http://btc.blockr.io/chartsback up on the 4th You can't quite chart perfectly with the above since the 27th is straddling both diff numbers but 1233 blocks were done in 8 days 'normal' is 8 x 144 = 1152 so we are up 7.03% like I said we are missing part of Jan 27th and today feb 5 on Jan 27th we made 145 blocks I do not remember the exact time we switched difficulty but if you include all of Jan 27 we go to 1378 blocks in 9 days normal is 9 x 144 = 1296 so we are up 6.32% And 1 more big one 159 means 1537 in 10 days this is around 6.73% if you count Jan 27th and the biggest number in a few weeks 171 this is 1708 block in 11 days = 155.27 blocks a day or (+7.82%). What does it mean? I would think a big boy like KNC or Bitfury is bringing a plant on line. Others may want to say variance but not this time.

yes, painters tape is good too
why i said to raise it, is because the fan is really obstructed the way you have it now.
the difference in temp from floor to 10inches above floor is almost none, but a good airflow is best!
I will attempt to raise it later you may be correct about the fan blockage. The tape seems to be helping. this is a new number with window closed. very good hashrate but early.  Philip, Have you found that on your test miners that there are Frequencies that work at higher points rather than lower? Example - I have most of my miners at 392.75 - some at 400. Some got x's at 400. Is there reason to think maybe that a miner that x's out at 400 - might actually work at 412? Cheers, Strato The two I had both can do freq 412. but cold rooms and lots of fans are important. As for good freq vs shit freq. I have found that 275 was not good and 318.75 was bad. The key for overclock is look at the HW as long as they are under 0.05 good rates show up. for me 412 is very good 425 errors got high 0.088 and has was lower at 425 then 412. You need to wait at least two hours to see: the rates settle the errors settle the temps settle when you get over 375 freq . Also the pool you are using can affect hw's. I built a 1 dollar 4 sided should using a cardboard box and duct tape . not sureif it helps will continue to test. |

Hi. Thanks for the flowers I didn't want to injure the outside skin. Also water-proof silencers are much more expensive. It would be nice to suck in the air from the top, but also rain comes that way so I abandoned that idea  yeah you built a really nice piece of gear. It is too costly because buying 114 s-5's or 114 sp20's don't put you ahead of the curve due to the terrible price of BTC. If I could get this miner https://bitcointalk.org/index.php?topic=944406.0It would work. this miner does not exist . putting 114 s-5's or sp20 in that crate won't pay off. Now if I had cheap power yeah maybe. I do like the build. |

Difficulty is a joke right now with the recent price slump, where's all the hash power coming from and how are they affording to operate?
well if it is not variance and it is hash, then it is a major company using 'special' gear Say bitfury adding 30-50 ph. In theory they should be building a major plant in the north of Finland or maybe Iceland. |

It's gonna be tough all round with BTC holding in the low $200's and diff looking like it's going up again  Its even tougher for ppl holding their miners hoping to get ROI. Phillipma's opinion does not count because he got "free" electricity with his rent. I feel bad for ppl who just bought some miners tho.... however, it is a good time to get *some* used gear at good prices. I pay $0.09 USD for nighttime and $0.13 in the daytime/peak, so am still somewhat competitive. and im hoping to move into ~$70/kw/month colocation very soon Yeah I am hoping to share part of a location in Wash DC. I would drive 8sp20's to it. Pay a piece of the power and mine. Keep 1 s-5 1 avalon4 1 sp20 in house |

yeah The ddos attacks come when we get over 60% cdf more often then when we are low cdf like 20%. I guess they figure the miners are more invested now after buying hash or hashing for a week and no payout.

scotch tape all the bottom from side to side. scotch tape as much as possible the top of the unit!
Philip, u need to raise the unit a little bit more. ~4 inches might be the best....
I will use some painters tape as it removes well. The closer to the floor the colder the intake air is. I may raise it : 1 more inch then 2 more inch then 3 more inch then 4 more inch to find the sweet spot. I am doing a solid 1320-1335 gh and not that hot. |

Dogie is correct that the air escapes from the bottom and top of the unit. see this photo. Dogie is wrong that it is not cooler at least in my case. It is cooler this way with 1 unit in a 12 by 12 by 7.5 very well insulated room. It is 1 or 2 f cooler with the window shut. It is 4 or 5 f cooler with the window open and outside air was 15 or 16 f this morning a lot of air comes out of the bottom of the unit. IN this photo now the bottom Is a wall of aluminum heat sink facing us I am going to make a solid bottom over the weekend will post on Monday. look close I have a few heatsinks on the unit.  |

no it is on the floor next to the spare bed. I just checked it and the room is too cold with the window open. Here are the numbers on the 1 piece. I will post some photos later.  that is a stainless steel grill it allows cold air to be sucked up from the floor. it was 73f on the floor with the window closed  window was open last night that 9 volt battery is for scale  the grill is spaced to let air in close look at the ss grill  the actual fan grill is spaced about ½ inch  |

This would have been nice to have last year, but this year prices make it too costly. 100 kwatts are about 140 s-5s since you have 114 plugs lets say it will do 114 s-5s' 114 x 1.15 th = 131 th
At 8 cents a kwatt . that 18000 usd unit take 81 days to pay off.
I have left the shipping price out.
I have left the psu price out.
I have left the s-5 price out.
I have frozen the diff at 42 and in 3 days it is going to 45
I have to say it is a nice piece of gear .
I would love to have filled with s-5's mining in a warehouse using some low cost power.
Good luck selling it.

Well I've got my 2 S5's running together. Literally. Looks like 1 of my controller boards is not working properly, so I decided that I would make both of my S5's run off of the same controller card. Here is my Status page showing both S5's running off the same controller board. The temps are little warm but I'm adjusting some fans and I'm powering my fan's externally. http://www.411px.com/2xS5.jpgAnd here is some true to it's name S5 miner porn. http://www.411px.com/S5porn.jpgwith a good old evga 1300 g2 acting as the lube . (well the power source) |
