Batch 8 ist mir nicht sympathisch... also halt bis nächstes Jahr warten, was scheisse ist..
why not, looks okay to me. sorry, don't know why I wrote German^^ Because it's less hashpower and more power consumption previous batches. I would like something like batch 5, kinda like that one. hahahha i had to google translate that. i understand people say its an overpriced already overclocked model, but people with batch 1-5, how high can you overclock it without too much hw ? im only going to try that after 90 days though for warranty purposes not only HW errors, but about an extra 100w for a few hundred GH.... in my experience it is almost ALWAYS better to underclock then overclockit was the case with SP20/SP30/S1, but not really the case of S7. It stays pretty much close to 0.25J/Gh, in overclock and underclock. The little difference is probably all due to fans. As far as HW errors are concerned, B5 went from 0.0000 (13 errors in two days) at 600 to 0.0030% at 625, which is fine. |

My B4 at 575-1156W at the wall with EVGA1300 G2 gold (0.2513 J/Gh), 4600Gh 3960/3840rpm, 77F (25C) ambient
MY B5 at 625-1289W (0.2577 J/Gh) at the wall with EVGA1300 G2 Gold, 5001Gh, 4200/3960rpm, 77F
B5 was 1250, not 1210W at 600 with fan at 4400/4080
I mention fan speed because it affects W at the wall, naturally.
Was not with 220V and 40% Fan no, 110/120V and auto fan for both. Did they specify 40% fan for 0.25? I tried lowering fan on B1 and B2, but results were that they somehow overheated even when sensor was reading OK temp, and as a result had some software glitches, so I stopped lowering fan below 65. In any case, I do auto for a few days to let them "settle in". the difference from expected J/Gh is quite small and so far, I am quite happy. |

Batch 5. Not too shabby.  did anyone do a wattage at the wall at 625? I was pulling 1170 at 593 if memory serves. My B4 at 575-1156W at the wall with EVGA1300 G2 gold (0.2513 J/Gh), 4600Gh 3960/3840rpm, 77F (25C) ambient MY B5 at 625-1289W (0.2577 J/Gh) at the wall with EVGA1300 G2 Gold, 5001Gh, 4200/3960rpm, 77F B5 was 1250, not 1210W at 600 with fan at 4400/4080 I mention fan speed because it affects W at the wall, naturally. |

Yes I had seen that. I wonder if they are essentially the same with the exception of which freq is default. My batch 5 came with the latest firmware on it. interesting...my batch 5 still has the Sept 15 software. It gets to 5001Gh at 625 "Like a BOSS" with 0.0029% error so far. We shall see. |

<clipped image> showing ~5th at 625mhz
do you need new firmware for the 625mhz? no, but doing this is negating the warranty, strictly speaking. |

Thanks, very interesting... You probably meant 135/3=45 chip blade. I would love to have 135 chip blade instead  |

Overclock contest? I should have put in Max, the 488MHz Compac that I couldn't get more out of because it was killing my hub. Course that stick isn't exactly stock.
Will any of the last 200 be like Max? End of the Season special, perhaps  |

That's the hub (Superbpag) I used for the 24hr over-clock contest run in the compac solo club. Ran one stick with Y set-up at 435MHz got/getting 23.87GH (I haven't shut it down yet and in about 10min it'll be 36hrs run). can usb connector even handle the Y setup on this hub (rhetorical question, of course)? doubling from 2A to 4A per slot? It looks like a nice hub. Only problem is a lot of us RPI users are using 2.0 , USB 3.0 Hub's don't seem to like RPI. Hopefully they come out with a RPI that can handle most usb 3.0 hubs someday. Until then I will be gettin 2.0 for the most part. Just hard to beat RPI as a controller. actually, someone (Jake36, probably) specifically mentioned that this particular usb 3.0 hub (Superbpag) handles raspberry pi well, if I am not mistaken. |

1 Milion Club = Who own more than 21BTC
100 Thousand Club = Who own more than 210BTC
10 Thousand Club = Who own more than 2100 BTC
1 Thousand Club = Who own more than 21000 BTC
1 Hundred Club = Who own more than 210000 BTC
50 Club = Who own more than 420000BTC
21 Club = Who own more than 1000000BTC (Only Nakamoto i think)
This doesn't really matter when Bitcoin is worth only $300. Maybe when the price increases ten fold or even hundred fold (  ), membership of these clubs will be something to write about. Now, anyone can be part of the million club by purchasing a few coins. Not everybody has 6k usd laying around to risk at bitcoin. 6k may not be much for you, but for someone else it can be a whole lot. Though, I guess anybody who is a member of the 1 million club will have a good life ahead I can't but agree with you! $6,5k is quite a lot of money, even for the Western countries people! I won't even mention poorer countries people! Of course I am talking about the normal, not too rich people. Rich people don't care will Bitcoin be successful or not! Actually, making rich people caring about bitcoin is the fastest path to bitcoin appreciation, no doubt. I know the lore here, but somehow a thought of 100K bitcoin does not ring a bell for me anymore, maybe because rich are not participating much, there is way too much resistance to bitcoin in the populace, governments are making a fuss, etc., etc. |

Again, apologies for taking some offense. I get so many people who have been so misinformed about mining that look to blame the pool or me for their ignorance, directly or indirectly. Your post read a lot like, "my balance changed for no reason, the pool must be cheating me."
I agree that the stats and website need a full overhaul to make some things more clear and better looking overall. But they are correct as they are. The balance numbers come directly from the reward system and are just parsed and displayed.
My post actually said that I was puzzled, and then you explained (in more pertinent part of your post) how estimated change is handled. I stayed, but now actively considering leaving for the following reasons: That long term account which you referred to has luck of 91.4-91.5% right now, which should have almost never happened according to this: http://organofcorti.blogspot.com/2015/07/faq-bitcoin-mining-and-luck-statistic.htmlthere is only 1/1000 chance of luck being 91% in 1000 blocks solved by a particular pool. The account that you referred to, again, has 91.4-91.6% long term luck (more than a year). In the last 12 mo your pool solved 1644 blocks or close, if I am not mistaken, so probability is even smaller than 1/1000 (organofcorti has no numbers for >1000 blocks). basically, it can only happen less than one time (one year period) in 1000 years. I know that you have some ad hoc timing explanation, but ad hoc does not explain statistics. While NOT suggesting or implying (directly or indirectly) that something is intentional, it looks likely to me that some calculations are not done right at the back end. I don't know what it is-stale shares handling, manual payout cutoffs, higher than 100% luck calculation, etc, but in the end it is just not right, and by not right I mean that these numbers are very unlikely to happen. |

thats weird. but just looking at the price, wouldnt a batch 8 be better ? Maybe Batch 3 is on hand and ready to ship because they were available for the orders that weren't shipped? Batch 7 and 8 won't arrive for about 1 month or more. So a Batch 3 arriving by the end of next week should be a better. Guys you won't get a batch 3 order if you place your order now through that link.. Bitmain told me about this glitch and said look at the web URL and its date, and the shipping dates. It's an error on their part as they forgot to take down the page. i was wondering the same about batch 7 because when ordering it was named: "Batch 7-sold out" |

I saw that some are using this PSU EVGA SuperNOVA 1300 G2 1300W for their S7. How's it working out?
fantastic-no probs so far, but you need two PCIe extenders that you connect to singles and then balance the load. I do it it the following way: first row: Position 1 and 2-two connectors from double headed red cable, Position 3-one connector from a "single" that was split with an extender cable second row: Position 1 and 2-two connectors from double headed red cable and Position 3-second connector from an extender third row: Pos1-single red cable, Pos2-single red cable, Pos3-first connector of the second extender connected to a single red cable Controller-second connector of the second extender I bought extenders from either Startech (they are 50% more expensive, but connect very snugly) or Jacobs parts-those do the job, but sometimes take a few seconds to fit them. Both are 18 awg, which is enough for the task. Startech-$6/cable Jacobs parts-$3.95/cable on amazon -search for "PCIE split cables" |

What is the safest standard markings good to use for S7s?
Can I use this: 10Amp 18AWG ?
markings? you mean PCIe cables or power cable? if you talking about PCIE (12v) or power cables (110/120V), here is the relevant reference: http://www.rowand.net/Shop/Tech/WireCapacityChart.htmget to the bottom of that page it says: at 12V 20awg 8amp max per wire, but PCIe has two, so 8X2X12=192W as far as wire carrying capacity is concerned. 192X9=1728W, much more than 1210W S7, so according to this, even 20awg wire is OK, but most good ATX PSU have at least 18 gauge wire (can carry 10A ea at 12V) at 110V 20awg-only 7.5A, so you need 14-16awg power cable, 18awg is too low as 1250w/110v=11.36A, which exceeds 10A limit for 18awg cord. You get half a current at 220V though. |

just shows that there are no "real" batches between 1-5. They all have 9/15 software, BTW, and that includes "Batch 5". One would think that if a miner was produced in the last two weeks, 10/23 software would be loaded, right? |

Yeah, it looks like greed got the better of a few people at the top. That and the fact that the price of coins tanked right after the release of the SP20. I got the 15 unit special for $5000 w/ free shipping in January and I can still sell the units used for more than I bought them for. I heard they lost money on that deal and it was the last time they have built a miner as far as I know.
To be totally honest I'm almost positive that the SP50 is never going to be finished. I'll believe it when I see a picture of a real one working, not the 3d mock-up and untested theoretical numbers. Its going to be a lot harder to make a perfect working model than most think. Not that they can't, I just don't think that given what I know so far that they ever will.
If nothing else I give SP lots of love for things like that SP20 special. It is rather rare you can mine with a machine for basically a year and still sell it for what you paid for it. That sure addresses everyone's #1 (and pretty much only) concern of making money... BTCS right now has a market cap of $18,469,000. How is that even possible? Not a bad setup, loose millions and still be worth tons... Well, for now at least... market is discounting the probability of them getting 5-10 mil, finishing SP50 and getting 5-10% hashing share for 12 mo afterwards. If it happens, i can see them easily getting 30-40 mil EBITDA. |

First of all, I have absolutely NO accusations, just trying to understand how the calculations work, seriously, so please don't take offense.
That said, I don't think that you explained this, at least not at the level I assume most will understand.
What exactly is an estimated change? Estimated change, i suppose, by common definition of the word is something that happened ALREADY, right?
So, how estimated change can go down EVEN if one miner is disconnected? How did future affected the past, unless this word means something else in this context.
Still, manual payout at point B (today) was exactly the same amount that miner earned at point A ( EDIT: actually at 12:43 this morning, sorry), which is OK If no blocks were solved between 12:43am and 3:27 pm. I don't know this for a fact, but assume that it is correct-you can confirm it if you want.
Then the question is: if remaining miner was hashing during this 14 hour period AND estimated change went backwards (less at point B then at point A), then WHERE did its hashing go?
Bottom line- I have the same miner pointed to your pool; I would have left if i thought that something is purposefully wrong.
I just looked for some clarification, no need to be upset, really.

i still think that this is just a software glitch especially with forwarding, because someone had to either hack into your computer or router and if so, you have bigger problems than just a miner.
also, when you say...stole a miner...do you mean that your miner seized to hash to your pool and was hashing to another address?
if yes, then it was hacked (unless it defaulted to factory settings), if no, then just a software glitch.
I don't think it was a software glitch because at the same time it stopped hasing on the pool I chose, I belive it was set to mine somewhere else  OK, but then look at that reddit that the OP just posted-you might have bigger problems than just a miner. It is possible that your computer and router are compromised as well. |

You're not the only one , who is happy. I am also happy when they do not produce this super monsters or they come too late. I am also happy, that I sold all of 17 x SP20 and when Spondoolies are sold spare parts at normal prices , then I'd bought a controller for SP20 and get one more sales. Now I have a beautiful SP20 empty shell and rare fan, for some miner projects. I actually feel saddened by this putative demise which, hopefully, will not happen. I enjoyed my SP20s very much with all tuning that was possible. |
