The batch 4 will not start for a while. My guess is Next Friday.
As for me I ordered batch 2 on the 29th paid for it on the 6th due to the underhashing issues on my batch 1 which took me 2 days to trouble shoot and post a fix.
So no shipping info on my purchase. Just waiting for info I hope to hear from them.

just a weekend there, we will probably see new batches on Monday or even sunday pm.
It's possible we could see Batch 4 and possibly Batch 5 with it as well on Monday. However, new batches may not be available until Friday of next week. I think they would rather be more prepared to ship orders out within the time frame they specify to improve customer satisfaction and to relieve pressure of meeting deadlines. However, I'm not there and I cannot see what they have or have not done.
If bw will really produce something in winter time, BMT will be pressed to accelerate the 14/16nm rollout.
I don't believe they would feel hard pressed. I think the mark up with the price of the S7 may be quite considerable in relation to actual costs. Which means, they would still have room for price adjustment if they desire. It all depends on the price of BW's gear IF they actually sell it. Miners will be calculating ROI on rigs made available by multiple suppliers and will purchase which ever rig they deem as more viable for their situation.
Again, this was only speculation on my part.

Bitmain is all sold out of all S7s Batch 1, 2, and 3.
SPECULATION (without any facts)
Is there an introduction of a new product? Maybe with the new chip.
Are they releasing the new S7+
Are they now trying to catch up?
Are they freezing sales to avoid loss with the increased BTC value?
Just Saying

Getting caught up, IMHO.
IF an S7+ were to come out, that would not stop them from making the S7, IMHO.
I do not see a new chip (14nm or 16nm) coming out until possibly this time next year, IMHO.
I personally do not feel they are freezing sales. If the price of bitcoin continues to rise, they could simply continue sales while increasing the price of the S7's in proportion to the rise in bitcoin price and difficulty to continue making profits.

If I was to give a suggestion to bitmain engineers it would be to force a higher initial fan speed on reboot, like SP20 was doing.
The way it is currently setup, upon reboot there is an abrupt change from high speed fan to initially low speed, which I think is causing temporary chip overheating. Board sensors are not highly relevant here because sensors are probably removed from chips. I think that this putative chip overheating might be causing the initial higher error rate upon reboot. Once fan reaches high speeds, the system equilibrates and errors decrease.
Yes, whatever the reason it is something that Bitmain ought to deal with. It may be thermal related as you suggest, but it may also involve details of how a chip disables cores that are creating too many hardware errors. The restart problem doesn't seem to me to be thermally related, because I've seen roughly the same situation with room temperatures more that 30 degrees C different. (If the problem is an algorithm hardwired into their chips, I doubt we'll see any improvements.)
yeah, most likely the actual chip function as it is unlikely to be temperature driven if 30C ambient difference shows the same effect. maybe abrupt shutdown also messes up with chips as well.
i had killawatt that died and S7 was connected through it. Once I restarted the miner , it was showing lots of errors for the first couple of minutes, which mostly disappeared upon soft reboot, but it too good 1-2 hr until error rate came back to usual 0.0064% and stayed there.

Finksy, I've got 2 2880 PSUs powering 3 S7s. Originally I thought I would put one complete S7 on each PSU, then split the third one across the PSUs.
In the end I put one S7 one one PSU and 2 S7s on the other. I figured that two S7s on a single 2880 PSU only take up 80%, so that seemed reasonable. Also this configuration is simpler to keep track of in case I ever need to power cycle the PSUs from the PDUs (this is all deployed at a data center).
Of course one PSU is underburdened, but them's the breaks. I don't have enough physical space to add another S7.
Another potential drawback is that the 2 new S7s that are on a single PSU are both very strong performers. They are candidates for overclocking, but then they're eating into that 20% headroom.
Does the above configuration make sense to you, or are there tangible benefits to splitting the third S7 across the two PSUs?

2.5 S7's on each 2880W PSU would be pulling 2,825W, or 11.77 amps. The problem is you can't divide 5 S7's (15 hashboards) evenly, so one PSU would have to take on ~3,013W (12.55A @ 240V), and the other ~2,636W (10.98A @ 240V). If you want to power 5 S7's I would suggest running a single hashboard from one of the S7's on a separate PSU (should draw ~377W DC), leaving you with 7 hashboards + controller for each 2880W PSU's loaded @ 91-92%. Better for longevity and efficiency, and almost all of us have small PSU's kicking around somewhere.
Plus, since the 2880W boards have 22 PCIe connectors, it's enough to power all 3 PCIe ports on all 7 hashboards + the controller.

Thanks for the additional brain storming for me, Finksy. I do have 9 x Corsair AX860 PSU's along with the 20 x IBM 2880W PSU's. I don't need all 20 x 2880's yet. That will not begin until December. So, I believe I will plug in 1 x 2880W and 1 x AX860W PSU in each of the 15 amp legs of my 30 amp PDU's to be able to power 5 or 6 x S7's.
EDIT: So, I believe I will keep it to 5 x S7's at 600 MHz stock frequency per PDU instead of 6 x S7's under clocked at 575 MHz. That would be configured the following way for each 15 amp leg of the 30 amp PDU: 1 x 2880W PSU powering 2 controllers (20 watts) and 7 blades (2800 watts) and an AX860 watt PSU powering 1 controller (10 watts) and 1 blade (400 watts) on one of the 15 amp legs of the 30 amp PDU for a total of 3230 watts (13.46 amps). Then have 1 x 2880W PSU powering 2 controllers (20 watts) and 7 blades (2800 watts) for a total of 2820 watts (11.75 amps) on the other 15 amp leg of the 30 amp PDU.
Thanks again for the brain storming.
EDIT: I know the blades are actually 377 watts each instead of the 400 watts I stated when rounding off and the controller is probably a bit more than the 10 watts I stated. Anyone have any idea about how many watts the controller is?

he said 2 of them can do 5 s-7's
so if each s-7 pulls 1200 watts 5 x 1200 = 6000 so the psu needs to do 3000 watts.
I would be willing to guess based on my testing 5 s-7's set at freq 587 would do under 5760 watts psu needs to do 2800 watts
so yeah I think you could do 5 at freq 587 or less.
the savings in psu's on 50 s-7's would be 50 x amtminer psu vs 20 x 2880 psu
even if you got say 4840 on all the antminer psu driven s-7s'
and only 4740 on all the 2880 watts psus.
the savings in psu cost would make up for it.

Thanks for clarifying that he said 2 x IBM 2880's and not just one (1).
Here was my dilemma: My 240V/30A PDU's have two (2) 15 amp breakers built into it. The maximum amount of amps I've been able to go on one of the 15 amp legs of the PDU is 17 amps without the 15 amp breaker on the PDU tripping.
After thinking about it... I still cannot do 3 x 2880W PSU's on the 30 amp PDU's. 2 x 2880W PSU's would have to be plugged into one of the 15 amp legs of the PDU. Which means one of the 15 amp breakers built into the PDU would trip all the time and would not be able to power the 3rd 2880W PSU. See my dilemma?
This is why I was mentioning buying the BM1600W PSU's to go along with IBM 2880W PSU's while being connected to 2 x 15 amp legs with breakers built into the PDU. Now I'm wishing I had 40 amp or 50 amp PDU's.
Here are the PDU's I have: http://www.tripplite.com/metered-pdu-30a-208v-240v-0u-vertical-c19-c13-outlets-nema-l6-30p-single-phase~PDUMV30HV/

I do not think reward halving will have impact on S7 price. Tooo much time until that...
I would have to agree with you on that one to an extent. That's the only thing I could come up with for the price reduction between batch 1 and batch 3.
I think the key is it will not yet. But once we hit say 6 month's, then 3 months etc no doubt it will effect it. With less reward people would not spend as much.
But we really don't know a lot of what will happen at halving we need to know to determine miners price. BTC price at halving will affect miners price greatly, and no one can tell us what that will be currently..
Agreed, we don't know what will occur with difficulty and btc price.
I plan on buying more every month. I'm not saying how many each month but it will be quite a bit. I plan on buying ten of their 1600 PSU's as well. The way my PDU's are set up, I still have more watts available on each PSU for more S7's. I would rather do this with BITMAIN's PSU's than use an IBM 2880W PSU to power only one S7 when it can easily power two. It would be a waste to do this with an IBM 2880W. Hence, the need for BITMAIN's 1600W PSU.
I've been up all night. It is 5:39am at my location now. It's past time to get some sleep.
Good night everyone!
I must be missing something, so power 2 with an IBM 2880W PSU if that is what you can do, heck power 5 per 2 IBM 2880W PSUs. You have lower cost, and better efficiency than Bitmain PSUs, I am not understanding the logic since you make the point you can power two per PSU.
Sounds like I'm about to learn something...
You mean to tell me I can run more than two S7's with an IBM 2880W PSU
I assumed it can do about 3200 to 3300 watts max. So, I can actually power 5 of them safely? October 23, 2015, 11:22:11 AM
Sometimes the error rate can stay high after a system reboot. (Sometimes even after several system reboots.) In that case, I've found it useful to power cycle. Let the machine run for a few minutes and then system reboot. This seems to get things back to a low hw error rate with my unit. Then I can increase the clock rate, hopefully this time to a value that won't screw things up. Presently my early batch 1 unit is averaging 4.87 TH, 618M, 57c, fan 3000 rpm, 1d21h. I plan to leave it alone unless something changes for some reason or other, such as a power interruption.
If I was to give a suggestion to bitmain engineers it would be to force a higher initial fan speed on reboot, like SP20 was doing.
The way it is currently setup, upon reboot there is an abrupt change from high speed fan to initially low speed, which I think is causing temporary chip overheating. Board sensors are not highly relevant here because sensors are probably removed from chips. I think that this putative chip overheating might be causing the initial higher error rate upon reboot. Once fan reaches high speeds, the system equilibrates and errors decrease.

Rumor has it that orders placed as late as October 10 have been shipped.
I think it went out of stock around that time so chances are that all Batch 2/3 miners might be on their way. Check your order history.
