Bitcoin Difficulty shows it going down a little:
Bitcoin Difficulty: 54,256,630,328
Estimated Next Difficulty: 56,836,275,848 (+4.75%)
Adjust time: After 680 Blocks, About 4.5 days
Hashrate(?): 415,963,691 GH/s
Still a pretty big jump though compared to our normal 2.

it has 6 jacks 4 cables have a single plug and 2 cables have 2x plugs so you get 8 to plug into the s-7 it can just do the job. but it has less cables then bitmaintech wants you to use. They are afraid of people using cheap PSU's/cords and make sure to warn 3 all over. I suspect they pack a paper with each S7 warning of all the different things and an email. If you know what your doing and quality PSU 2 should be able to do it.... but if any issues if you tell bitmain you used 2 chances are they pull warranty. I'm not saying to do it but I have a feeling some will use two and just not mention that to bitmain if they need RMA. Sidehack also had a good idea. If you use a proper splitter (not a cheap to small of wire one) bitmain did not say no on that... but they could consider it improper powering as it's vague. So someone might ask on proper guage splitters what bitmains official stance is. |

2x 51.3dB for fans 2x 30dB for PSU so ~55dB.
I think you may be in error with this, as it appears the S7's are using the S5 fans, and the S5 fans are quite loud in the ~70dB range. If I had any reason to think the S7's were capable of running at ~55dB, I probably would have purchased one to replace a bank of older miners, as that would be quieter than the S5's. I believe they are using S5+ fans not regular S5 fan's. And I could be wrong on that. But I think they kept S5+ fans. |

Can you take a picture of status page after it starts in a few minutes of running? Is it getting full speed?
Make sure to power up all hashing units before controller aswell. Let us know what happens!

Taped out, probably sometime early July. Still takes a few months to get working PRODUCTION silicon after that point, especially on a new process node might take longer to get yields enough to start selling chips and building machines.
Patience. All appearences are that Sfards will have competition from Bitmain soon, and both SHA256 AND Scrypt competition by the end of the year or very very early next year.
This is all speculation. We have no idea what they have. I think going after 2 chips at once is pretty ambitious. I would guess it would slow down process going for A3 and A4 at same time. Most seem to pick one chip and focus on it ... then release. I think it would have made more sense to focus resources get one out then change into other. But they are not doing that. Sfards/Gridseed and KnC were the only folks BESIDES Innosilicon to do both Scrypt and SHA256 chips. Innosilicon however had an already existing chip design business, which was unique IIRC among all ASIC designer/maker companies for cryptocoins. I suspect they have a LOT more resources than most - might want to keep in mind they managed to develop the A1 AND the A2 from internal resources, never did a "preorder" on them at all. I'm just looking at releases. To take on two new chips is ambitious. And they have not pushed one out yet. I still think doing one then the other would have been a better idea. SFards/Gridseed has a chip, KnC is really not personal use anymore, Bitmain has chip. They need to deliver something. Sad to see things get so centralized and based on the output of a few companies not honoring the spirit of decentralization. There is such a entry barrier it will only get fewer most likely. It will become relying on chip manufactures. Some have made announcements but no real releases. I hope SFards will still release this at a lower price, but they have been quiet for a LONG time. I honestly wonder what their idea is. |

Ouch bitwisdom looking like this difficulty could sting we can hope it is better next one, but I think the next gen is here.

S5+ coupon's are 100 it appears.  |

What PSU are you using? That is if you are really asking an question. Not sure with all ? looks like possible troll. |

Guys, can you use two 750W PSU to power this miner ?
not at all You need 410w at the wall for each hashboard, from ONLY one PSU... Well you could use different PSU's for different hashing boards. I would prefer one though. Biggest thing is not to mix psu's on hashing board. IE one hashing board and two PSU's going to it. |

No forum moderators can't see your IP but admin can who are, Badbear and theymos. IMO admin dont mostly see your IP, I've only heard of them doing so in account hacking cases.
Also the hack a while back at least had some IP's. I made a joke about who ever was getting on old accounts to impress me and they were able to give my IP.... Here it is - https://bitcointalk.org/index.php?topic=1068623.msg11449839#msg11449839 . I was on that IP a little bit as it was kinda static but has luckily changed(I got fiber and now my IP is luckily easier to flush). I only reported to admin's/mod's when that was considered "new" |

this mess tourned out even more complicated now with all those fork, they should just stick to core and implement the change to the tx block size
we don't need to turn the table in favor on miners, when there are already dangerous thing like chinese controlling 60+%
I predict this amount only goes up. After having I really want to see numbers. It also depends on BTC price but it's been to low for to long. I still am holding as I believe. Hopefully one day it pay's off. |

Thank you, but these have all been tried.
No change!
What PSU are you using you never told that? This could cause only one depending on which one. What brand and how many watts? |

I've been turning away DPS2K sales all week on account of we're out of stock. I had a choice to put money down on a new batch of boards or buy some new machinery, and since it took most of a year to sell the last batch of boards it didn't seem a good investment.
A pair of my 750W Dells load-balanced should run an S7 quite nicely. A single 1300W server supply should also do pretty well. You're right; a lot of supply kits are gonna get sold in the next month.
Dang I was honestly hoping some of those would go your way. I love that you have a good ethic twords how you treat people, and think highly so far of your products after testing the usb drive. I can understand the decision. I think few were expecting them to keep S5+ design. I would have bet for sure it was going to keep 2 blade design. I do give bitmain credit on finding a way to make more choose their psu though. They are the other one to pick up sales from having 10 PCIe on S7. I do fear how you mention junk wal-mart pci-e splitter. I fear some will try to save a few bucks and cheap cords will get hot and melt. I see that being a real issue if someone tries to go out to a store and get some of the off the shelf splitters. |

I wonder if they'd complain if he used a splitter from one of his nice sturdy 16AWG cables to a pair of jacks. It'd be pretty much just as safe.
Good question I would get a official anwser on it. I'm not sure they were very very vague on what improper powering could be. It for sure is using only 2 from their eyes. They emailed me a paper and sent one with S5+ to make sure I did not even think about 2 only. But not sure if you have them on a proper splitter as they don't say you cannot do it.... so more possible on that way for sure. two out of six evga 1300 cables are already split. i see no difference in splitting the other four as long as a single red cable can handle 266w (it will be 133w per connector, though). i don't have 240w in my house (apart from dryer and stove), so ordering their PSU is out of the question. Depending on your options I would look into 240. It really is nice to have using a PDU and being able to get a lot of juice is very nice. I do see that it's not the option for everyone. What I think is one of the server kit people are going to have a higher then normal sales rate with S7 release. I see them putting out a kit with enough PCIe cables on it. They have a few weeks from release date of S7 to get these kits in stock and sell them. And I predict they will do just that. |

Pricey. Good form factor though. Can reuse the same PSUs that I had for S5, fairly straightforward 2x upgrade.
not 100% as there are 3 connectors per board plus you might need a separate PSU for controller (at least this is what I read) I imagine that you would probably be able to get away with just having 2 of them plugged in. At least that's what I heard of the S5+ I would not spread this. Yes likely 2 can do it if proper gauge. But on S5+ they say and ship a paper with " There are 3 PCI-e connectors for +12V DC input on each hash board and ALL of the 3 are required". They also emailed paper to make sure you know about it on S5+. If you don't use 3 they consider it improper powering and it voids warranty on S5+ "b. Damage caused by electrical surges, lightning, or inadequate power supply;" I do not need 9x 16 gauge cables for 1200 watts, I wonder how much this will over clock to? If you get the same paperwork they sent with S5+ you might not "need" it as spec. But they make sure you use it to keep warranty. We have not seen for sure but I bet they ship same paperwork and email it just like S5+'s on using 3. |

I honestly think we have some machines being made and powered on. I just hope it does not turn into 5 percent as general difficulty change now. |

The question is about your PSU cables. The answer, then, is also about your PSU cables. If your PSU has PCIe cables made from 16AWG wire, it should be okay. If your PSU has PCIe cables made from 18AWG wire, I'd say it's a poorly-thought-out design.
I am pretty certain they are going to send same kinda paperwork S5+ came with. Even if 2 would do it if they catch you doing it voids warranty. So if they catch someone using 2 and in warranty I think they will void it from their paper at least if they keep it same as S5+. They considered it something thing like improper powering or something like that. |

Any news on the newest and latests SPXXX?  Please! otherwise i have to buy some s7  I don't think we will be hearing from SP in same timeline. Bitmain kept same NM chip... so they kinda had an advantage and it appears its gotten them a jump to the market of next gen. |
