I previously checked on the site for S5+ manual and firmware, but they are present now.

The manual makes more sense regarding the control board power connection, kind of...
It states to connect it to any power supply, but it is still worded oddly.
I am going to assume it must not matter, but I am at a loss why they say anything about it other than to connect it to a power supply unless there is something they are trying to tell us.

If anyone has any ideas what they are truly getting at feel free to post up.

Regarding the control board connection the manual states:
"...And be sure to connect the hash boards to the PSU first and then connect the controller to PSU"
"Connect connector on control board to any power supply"

If you are connecting the controller to the same PSU as hash boards, why does it matter if it is first or last, it will get power at the same time...
They have stated this several times, so there must be something there.

 and just because I love to repeat things that make me contemplate the mysterious statements in life I will repeat this from the manual as well:
"Higher input voltage will cause higher mining efficiency"

So how high can someone go?

I see improvements in this manual over previous generations. I appreciate there is a manual for this model.
I hope we see some clarification on the points made because whatever issue (if there is one) they are getting at with the control board power confuses the hell out of me. I previously thought that maybe they wanted the hash boards powered up slightly before the control board, but the way the manual reads with connecting to any power supply that can't be it and besides you don't want to be fiddling around getting that powered on with any delay when that many chips are putting out heat -- less fans.

I have seen an unfinished heatsink. It isn't cut out all the way. I will get a picture "from the guy" and get it posted. Overall it looks like a good unit. IT needs to be tested on a couple of other pools and ck solo to collect more data by "the guy" before anything lengthy is posted.





As far as the power I think you are worrying a little to much on it.  I think they designed controller unit to look for blades being powered on, so blades being powered on is a good thing.  If for some reason it the controller is booted up first and didnt work just reboot it Smiley  I have had 0 issues with mine.

As far as power getting more efficient not sure.  220/240 is more efficient then 110/120.  But I suspect almost all have it on 240 and not multiple 120's.  But not sure how far they are thinking.

What do you mean by you have seen a unfinished heatsink can you take a picture?

My highest temp is 44 C the ambient temperature is 25 C. 

I have almost no errors.  Pool reports slightly higher hashrates than the miner itself.

The 1x heatsink on each side of every chip really increases the heat dissipation.  It also makes the design dependent on constant airflow. 

After my warranty ends I will try using a fan controller and testing how low the fans can be set while keeping the chips at a reasonable temperature.

Did you change any fans on miner and where do you keep your miner? Air circulation looks like enough  Smiley

what an abomination.

It is actually a very nice miner from my experience with it so far.  It is not for everyone with the amount of electricity needed.  And also you do need a lot of PCIe cables I don't deny this.   But the recommended psu works great with them.

So far 1 day and 7 hours running not a single issue and running up to spec.   So actually looks good as far as miner stand point.

wut's your ambient temp & miner chip temp ?


My ambient temp is around around 78F which is kinda mild.   I think I have made it past most of the hotter day's in summer.   I have a lot of fans in my main mining room to help pushing new air.

One hashing blade is hitting 57c but most are hitting low 50's.   Very low errors and preforming as spec says.

I have an S5+.  I am running it on default freq with 3x evga 1300 PSU. 

With the PSU's I am using; each board uses 373 watts and the controller uses 185 watts for a total of 3542 watts.

I don't think anyone would necessarily have a problem running off of only 2x connectors on each blade so long as the PSU and cables they are using are very high quality and gauge.  However;

I also don't see the point in not connecting all three.  The miner costs ~ 9.35BTC.  Cables and connectors are nothing compared to this.

That is kinda my feeling.  I can see why people with PSU's with less PCIe connectors want 2 per.  But Bitmain made a big deal about 3.

If you have a problem and it's obvious it only had 2 plugs I think they will void warranty.  So that one extra plug on each to keep warranty valid is worth it to me.

tend to agree with this. if each board is drawing <400W you could provide that with only 2 cables. my guess is that it does two things:
1) prevents people from burning up cheap 18awg cables (that are limited around 150W)
2) slightly better balance of power distribution so the connector or copper traces dont fail

I absolutely understand that the official line will always be use all 3, however the technical explanation as to why you must use all 3 didn't really make sense.

Maybe someone who has an S5+ can tone out each side of the power connector pins. I think it's that simple, right?

If they're all connected with no resistance, then they're all going to the same place.

That would mean the pragmatic answer is you can probably use 2 16 AWG cables.

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.

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?

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.

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.

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?

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.

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!! Smiley


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 [email protected] , and if it works  using only 2 connectors instead that will be [email protected] 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.

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?

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.
