ANTMINER S5+ is available to order, 7.722TH/S 0.445J/GH

[Blockhunter]

You can use as many PSUs as you want as long as you don't have multiple PSUs powering the same individual board (of which there is 9).

Do all PCI ports need to be powered?  Or will it run with 2 on each board?  

2 is fine, still only about 165W per PCI-E.

Are you certain that using 2 is fine? The product description page says all three are required. It may be that each PCIe plug powers a specific set of chips; the 3 PCIe connectors may not share a common power bus at all as in, say, the S3 design. Without knowing the actual S5+ design, or having an actual unit to look at, saying "2 is fine" is only speculation at this point unless something more is known than what bitmain has disclosed so far.

Bitmain could confirm this here, but they aren't posting much these days. If anyone already has a unit, they could also confirm whether using 2 out of the 3 connectors works and post here.

What Bitmain customer Service told us was we have to use all 3 connectors for each board, As my understanding if each board need at least 382W(3436/9), in average each connector should be bear 127w@10.6A , and if it works  using only 2 connectors instead that will be 191w@15.9A for each connector , it is high risk to heat up or burn your cables if they are not good enough.    

This still doesn't answer the question of whether all 3 are *required* by design, or can 2 be used if the cables can handle the increased current?

BTW the power requirements aren't as high as you mention: 3436W quoted by bitmaintech is at the wall, using a 93% efficient PSU. So the DC power to the S5+ would only be 3436*0.93 or 3196 watts, or 355W per board. *If* the design allowed the use of 2 connectors per board, this would put 178W per connector (14.8A). This isn't bad, considering S3+ units can easily be powered with 2 PCIe cables and those use around 355W as well.

Of course we'll see another batch. There's no way that the S5+ is a one time event. But at this late stage there's no way it will run as long as the S3 did (what was that, 6 batches?)

Here's my fantasy:

1. BTC amps back up to the $1000 range just before Bitmain announces batch 2. They price accordingly at 2.3 BTC per S5+.

2. I place my order.

3. BTC drops back back to today's $240-ish.

4. Difficulty stagnates.

5. Profit.

Don't laugh. It could happen.

today it is $220-ish.  Tomorrow will be $200 ish

[notlist3d]

Here is my first testing with a S5+ - https://bitcointalk.org/index.php?topic=1157426.0

Finally got something big enough to need my 240.  Pretty amazing as far as footprint they put over 7T is a very small area.

Yes, it's not exactly heading in the right direction...

I've got a new fantasy now. On the new BM1385 chip announcement thread, suchmoon pointed out that the S3 was shipped a mere 2 weeks after the announcement of the BM1382 chip. If that means the possibility of the S7 being released in the first week of September, then I'm glad I missed the S5+ boat.

If there is another batch of S5+'s, they had better be heavily discounted or I'll just wait to see what happens.

so... x27 6pin pcie cables per miner....  im planning to use 3 hp 1200w power supply per miner... but.. 9 cables per power supply ..  this seems hard to do... anyone knows where to purchase those 6 pin pcie cables awg 16.. ?

If I was reading right, X28 6pin PCIE. Needs 1 for the control board.

If you use cables like this , you will need 9 of these . more tidy , main cable is 12AWG , and split is 16AWG .

Yes, this is true. You need a separate power cable for the controller, so people should take that into account in their planning.

It is crazy the amount of PCIe cables being used, but it does work great.   I used the suggested bitmain psu's and it is crazy they have pcie cables left over even after everything is plugged in.

But so far vary positive experience with bitmain PSU's.  The are not the cheapest but they come with no breakout board to mess with and no cords to mess with hooking up to breakout board.  So I was happy with them.

My first impressions of the S5+

It's smaller than I thought it would be.  
It runs fine with 3x1300 watt psus.  
It isn't any louder than a group of S5s.  
It stays cooler than S5s running in the same conditions at lower clocks.

There's a whole discussion around how many cables per board you really need. Bitmain says 3, but if it's just a matter of cable capacity and not how the board is designed to route power, then you can probably get by with less cables as long as they're beefy enough.

Did you wire your 3 1300w PSUs to handle 28 connections (3 for each of 9 boards plus one for the controller) or did you make due with less?

If you wired all 28 with Y splitters from 3 PSUs you must have made klondike_bar happy...

I wired each board with 2 cables, one being split to having 2 connectors.  All connections are filled.  I used 3 EVGA 1300 watt PSUs.  I really am impressed with how cool it stays compared to regular S5s.  My S5+ @ 325 frequency is sitting at 59 degrees while my S5s @ 275 frequency are sitting at 66 degrees.

They make a big deal about using 3 per board, so I would not try to personally.  They actually ship a piece of paper with some general instructions, and an email with it to.   And in all of them it made sure you use 3 per board.

So under pcie specs should it run if high quality psu with nice cables... yes.  But they make sure to tell you only run with 3 in each.  If you do 2 i'm sure it violates warranty.

Many comments I can reply to in one quote! The reason it says 3 connectors are required is because I wrote that long ago for S5, and they just updated the numbers in the announcement without reconsidering what it was actually saying. If you've got 16AWG then you could use 2 PCI-E from the same branch, 18AWG and you'll need 2 branches and you should keep checking on it for the first 30 minutes.

Only problem I see is if something goes wrong.   If for some reason you need warranty it seems using 2 instead of 3 might be "inadequate power supply" and void warranty.

If they would care/void warranty I have no idea.   Thanks for writing it out I didn't look into it after all the warnings, but glad to know it works for those who need it and have right equipment.

ALL the 3 PCIE connectors are needed to be connected to power supply on each hash board since it is based on serial power solution and there is no DC/DC inside the miner. Including the one PCIE connector on control board, there are 28 connectors in total.
Several PSU will be needed to support the miner, anyone spare PCIE connector from PSU will be connected to control board.
But be sure to power all the other PSU first and power on the last PSU which control board is connected in the end. this is very important!!

If you could, please elaborate for folks.
We are an unruly bunch, and while I plan to follow the rules, it would be great to know and understand the reasoning on a couple of these points. I do not plan to debate them, I want to understand, so please take your time, and explain them for us. Most / many of us are involved in the purchasing of miners for one of two simple reasons or both:
A. We like to gamble and take a little risk to earn.
B. We have a bit of an anarchist deep down who truly believe this technology will disrupt the monetary systems.


The points I see which require further clarification:
1. Why does the controller board need to be powered on last? Is it a matter of establishing proper communication with the serial chains? Did you learn something with the S5 which causes the three modules in series to have issues?
1A. I have a follow up regarding this to say, if it is truly important to power up the controller last, then why not require the controller to be powered from a separate power source? Will it void the warranty IF the controller board is powered by a separate power source? I can see this being dangerous if that power source failed since none of the fans will run and I assume all of the hash boards will melt down.

2. The instructions sent with the miner call for you to inspect each heat sink on the hashing boards to make sure none have fallen off during shipment. How do you recommend we do so without removing the hash boards? You can't see them all by popping the fans off.


My comments on using two PCI connectors are if you do it without understanding what you are doing and measuring the current being drawn you are simply asking for trouble. Why risk it? Why take more of a chance of causing cable issues and melting down your investments or worse, burn down your home / business? We stress our cables simply connecting them. Most of the break out board designs cause stress when you have all cable locations populated and then simply sit the miner and the power supply on the shelf and connect the cables. Further consider the heat in the US and maybe wherever you live. Unfortunately for me, we aren't done with 45 c and higher ambient (heat index) days yet and these babies are going to be pushed to their limits. Be smart and use all three. It is a safety factor as well as BITMAIN aren't going to cover your warranty when you charcoal a single PCI connector on the hash board.

[dogie]

ALL the 3 PCIE connectors are needed to be connected to power supply on each hash board .... since it is based on serial power solution and there is no DC/DC inside the miner.

Those two statements are unconnected and don't make sense as a justification. If each board can still only be powered by one PSU due to cross-loading, then each board's 3 PCI-E connectors are still connected. While we don't have any high res images to see if we can see tracks, each of the PCI-Es is still in-line and *appears* to be powering the same plain. That agrees with the cross-loading argument which would mean that each PCI-E is the same as the next, meaning the only limitation is maximum load and not because it doesn't have DC/DC.

[blarneystone]

Hello Bitmain,

Can you tell me what version of cgminer you have included in your firmware, & weather it is the mainline cgminer or your own forked version?

Also, when will a version of the firmware be available for download?

Thanks.

This is a particularly important question. Although it's easy to speculate why switching the controller on last is necessary, it would be good to have it spelt out why, also is this advisory or essential? My concern, as well as the one above, is suppose there is a brief power outage everything will the power back on simultaneously, or are we expected to have an automatic time delay built into the controller power?

[Finksy]

More importantly, if it's so crucial why the hell wasn't a time-delay built into the power circuit of the controller to begin with? Especially given most miners (think farms...) will be turning all the PSU's on at the same time with the flick of a breaker.

[crazyearner]

already s5 batch 1 pre orders sold out that sure was quick. Wonder when the next batch of orders will be available or to buy without pre order and in stock to buy. Tempted but no way in hell am  I doing pre orders ever fk that too much risk involved. Any details of when will be in stock to order as normal? or just going to be done in batches?
