okay I did a second order paid it and it is marked not paid expired.

so this does happen and it is late in China but I hope they fix this sooner rather then later.

Since Summer is upon us, as soon as I get notice that my last 2x s7b18's I ordered last night are shipped (great timing there ay what?) I will be ordering an s9.
Right now I have 4x s7's running at home being 5.2kw worth of heat load being added to what my AC has to handle so is a no brainer there: take 3 of the s7's off line and replace with the 1 s9. Introductory pricing be damned the combined miner and AC power savings make it a winner for me. Best part is that the ~1,350w load fits perfectly with the 1,800w (2.2kVA) Cyberpower always on-line UPS at home so no worries about dropping >14THs from low power line or blackouts (also have a permanent home generator to handle extended outages)
. For those wondering, got the GE 11kw whole-house genset ~ 3 years ago after my area of Detroit had a 2-week long blackout -- during a big summertime storm the local substation literally blew which in-turn damaged the feeders to it ... Of course since then the longest outage has been maybe 1/2hr at worst 
At least for now I can replace the last s5's I have at work with a couple of the displaced s7's and will have spares...

I wonder what the sound levels are like for the S9
I'm guessing same as s7.

Looks like the same fans so I'm going to guess that they're just as noisy as the S7. Can't wait to read a review on these but they are just too much for me to risk right now.

Quoting from the first page... sorry
Now you know what kind of beast they have in their farms 93.3 TH/s with 10 Delta fans on push pull.... tasty
Not sure what they have in mind for the controller board? It's populated for 4 Hash Boards and 2 Fans but has provision for 20 Hash Boards and 10 Fans...

based on my assumptions of difficulty movement (primarly a ~30% drop within a few weeks of halving), seems like with free power ROI takes 5-6months. With 0.07/kwh its closer to 10-12 months.
I can have one hosted at $0.06/kwh (+15% tax), and am likely to pull the trigger if it falls to 3.5BTC via BTCUSD price swings. At 3.9BTC, its a gamble - it would probably break even but after a full ~16month lifespan ROI would probably be 10-20% at most

So how long does it take to "Break Even" (aka ROI) if your expected -30% difficulty change doesn't actually materialize?
A 30% difficulty drop is roughly equivalent to a 420PH decrease if I am looking at things correctly.
i dont see that happening at all. It will go up and up.. We just saw a huge show of force on the network. If i was doing calcs id be factoring in another 600 ph increase over the next 3 - 4 months This is def a waiting game> Huge gamble to buy now before halving..

Probably the best bet right now. Wait and see what happens with the halving before putting any serious money in. Too many unknowns at the moment.

We will need to see a btc price above $800 to really have this make any kind of sense. Here is hoping the happens.
I see no reason it shouldn't. It's already begun rising from a very steady price, the halving is only a month away! We'll have to wait for the halving to see though. I've got good feeling
BTC price is not gonna go anywhere because of the halving. BTC halving price adjustment already took place last year when the price doubled from 225ish to the 400+ we've been healthily sitting at since this year.
You don't think it will skyrocket like it did after the last halving? I see no reason it shouldn't Like you said we've been healthily sitting at the same price for a long time, I feel this current rise in price is only a signal of the halving that's coming.

When will Bitfury announce their bankruptcy?

And of course I just ordered 2x of the batch18 s7's last night....

Each of the 3 Hash boards has 63 chips arranged as 21 nodes of 3 chips, and looks to be the same design as the 135 chip S7 with a Buck Converter feeding the string. If the voltage fed to the string was the same as the S7 at 10.5V this would give a core voltage of 0.5V / Chip.

It doesnt real create any extra time or cost to simply make the markings and a few vias in case of future designs. Even the S7 ad enough spots for 6 boards but noting became of it.
But I'd love to see at least 10 of these boards in a single ~50TH unit. Might not happen for a few months until the S9 price falls under ~$1500

I know that Bitmain's pricing history would make you think a price drop is right around the corner, but why would they do something like that when there is no REAL competitors at the moment?
Their pricing model has been to lower prices to keep competitive with other manufacturers.
They dropped the price of the S7 when Bitfurry looked like something that would encroach on their market share.
As it stands there is no one close to having a market ready product. On top of that, what real gains do you expect from the next line of miners? 14nm?? 10nm?? In my option that is still way off.
Bottom line is, I wouldn't expect a price drop this time around until something forces Bitmain's hand.
It's just business.

BW has announced a June release for a 14NM miner. So competition is coming.
May 31, 2016, 12:26:55 PM
So, really the S9 is a 7TH miner.... considering the halving =)
Well, at least diff will stay the same or continue to go higher now, due to this shitty release.
