My guess is 30 day wait for batch 2.
So say late OCT 21-25.
I think that, no later than after one week, the S7 is again on sale.

I bought on the first day, but probably later that day-no shipment info yet (unshipped in the account).
My order date: 2015-08-30 14:08:29 (From Bitmain order details) Not shipped yet. Wanna compare? ^^ Edit: I ordered 4x PSU's in the same order as my S7, so the order is marked as "shipped" on the website (cause they sent the PSU's). I'm worried they are gonna forget to ship my S7's! Have you gotten shipment info yet? I ordered 6 on the first day, but I paid with bankwire, hopefully they wont punish me for that! lol! Not sent here yet! They punish you for the use of real money for the payment. I ordered 4 x S7 on the first day. 2 x S7 paid with BTC are shipped. Two miners, which had been paid for USD , are not shipped.

I swapped blade 1 and 2 so that blade 1 would be the one showing the temperature reading. Still not working
I disconnected the "now" blade 2 and will not hash with only blade 1 but everything else looks ok.
I tried disconnecting blade 1 but learned it will not even start up without blade 1.... Not surprised.
I switched controller boards again but same result.
I will try to flash with latest firmware and see if that makes a difference.
If not, I guess I will try swapping out piece by piece until the entire unit is different. Fun project to take up a Sunday.
Update: Flashing firmware did not make any difference.
I offer you for 2 blades together 100USD + shipping costs US or EU. (depending on your location) No need for radiators and cables, only the screws with springs and 2 x blades.

Demand and supply are not always balanced.
A small example for Hashnest S5 market.
Shop Price: 367.0 USD(1.58579611฿) Stock: 627
Market Price : 1xS5=1 BTC
After the big panic selling S5 price with every day only go down. The reason is not only panic. S5 is still very profitable in Hashnest. Depending on the day Maintenance from total payout is 52-55%
But the S5 price only drops. Because supply is greater than demand. The same can also happen very easily with BTC.

Looking to invest in BTC mining,
got 5MWh coming from solar energy what is the maximum electricity price that could be used from such a plant for generating bit coins in profitable way. my cost for electricity cost is at 100euro/MWh. Is that price acceptable?
Looking forward for feedback.
Many thanks!
No, It is not acceptable for profit. Do not forget , you pay the tax from miners 19-24% even before you begin mining. And your cost of electricity is more expensive than hashnest. www.hashnest.comAntminer S7 4860 GHs Price: 1923.0 USD(8.30659141฿) Stock: 880 Power: 0.249w/GHS Maintenance Fee:$0.0005796/GHS/Day It all depends on how much you have own money to invest. Do not forget that you can also lose the investment. Overpriced solar electricity is not mining Resource... It is too late. Bitcoin train has already traveled a long time ago from your station and have left the European Union.

That sure is a lot of S5's. I'm curious if you are close to ROI on the hashnest S5's. I'm too lazy to do the maths on how long it would take to ROI on the S7's at hashnest.
Not even close to ROI My average S5 purchase price is 0.001217 BTC GHs 1,405657 BTC for S5 However, S5 possibility to ROI is much greater than the S7 ROI It all depends on Bitmain behaving, if the BTC price rises. If Bitmain raise the S7 price, has won all previous S7 buyers. If not , they are all lost. Hashnest S7 price goes down and S7 "never" ROI . Hashnest S5 market opened in early February. S5 price In February was close to the 1.8 BTC for S5 2015-02-12 1.7409 ฿ 2015-02-22 1.80835 ฿ 2015-02-25 1.7906 ฿ Today the market price is 1 BTC for S5 The same can also happen with S7 price.

what is your lowest s5 temperature on water? can't get water cooled s5 under 50C! is this normal? in the same condition, i have under 30C temperature on c1!
I have not measured the temperature of the water. It may be 35-40 degrees Celsius. Antminer shows 57-63 for six blades at frequency 350 .I am using SC-BC2 cooling kit http://shop.syscooling.com/goods.php?id=46

testing atm with File System Version Wed Jul 15 15:36:15 CST 2015
after 16m6s i have ~2,286.79gh
temp on the 3*12cm original C1 radiator is hooooooooooooooot! ~70c!!!
This radiator is not for S5 If you put other and faster fans, You can use it with 2x S5 blade. With original fans You can use it with formula 1 radiator=1x S5 blade.
|
|
|
So is it safe to run 4 blades on 1 controller?? thx!
Yes. 4 blades and 2 x S5 original FAN. My water-cooled S5 miners works for more than half a year with 3 or 4 blades.

Do you think the current migrant crisis in Europe has anything to do with bitcoin? Do you think the migrants are thinking that they can earn more btc in Germany vs. Greece vs. Turkey? Is there a way to donate btc to the migrants?
I speculate that a lot of these migrants are for bitcoins (economics), not refugees from war.
I think, that 99,999% of them are never in his life heard from BTC.

I think that after BTC halving we can see the dramatic BTC price drops .
It is very possible, that after halving Antminer S5 does not make a profit with Hashnest electricity price $0.001175/GHS/Day.

I'm disappointed with the heatsink falling off. I was hoping they would treat them like gold with RMA and get you perfect boards.
Was one heatsink all that fell off? Or did others seem loose?
I put with a akasa thermal adhesive tape a second radiator from BFL Single 25GH/s , and it seems that everything is working. But I'm also disappointed. I noticed the missing radiator only when I started to put blades in the place . I found the missing radiator in bubble wrap. It seems that this time it is used thermal adhesive tape, not glue. But I'm sure it's not a good design. Poor material for bonding the radiators, and more are not needed. Radiators fall like apples from the apple tree. Chinese autumn. Radiators were ready for picking.

I received today a parcel from China . Inside were two blades from S5 + Click to enlarge View the last image. One of the radiator is already off.
Of course, they did not send me a new FAN to replace the damaged fan... Shitmain Chinese warranty in all its glory.I decided not to buy any more S7. I have already sent back to China 3 x S5+ hashing boards. Shipping costs total over 120 euro. S7 has the same miserable Design as S5+. And it is really a poor thermo adhesive clue , which they used for S5+. You also can not put a new and better clue themselves. You can not just remove the old glue. If something happens to one of the S7 blades, you have to send back to China at the own expense over half a kilo radiators.
