0) General Information
The Bitmain AntMiner S5+ is the small miner that packs a punch.   I will do more of a hands on then a guide with this miner.   The reason behind my thinking is  with it taking 3436 watts to run setup will vary greatly depending on each persons setup.  This miner consists of 3 main modules with 3 blades in each.   The interesting thing about the modules is each appears to be built the same.  They make the main one with a controller screwed on top of the module.  But it appears if they wanted they could put controllers on any of them as they are built the same.

2) The Miner
Below are images to showcase the miner.




3) Install
The install is where it can very greatly for each person.  I personally went with a 240 volt 30 amp connection to a PDU.  From this PDU I used three of the suggested PSU's ( https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 ).  These PSU's made it very easy to install using one per module, they have more then enough PCIe connectors to give 3 per hashing blade.

The install time of the proper electrical cable, breaker, and pdu took some time but was done in a few hours even though a few snags running the wire.  I did this a day before receiving the unit so I had time to troubleshoot if needed.  Luckily no issues and all parts worked great.   

This brings to install time of S5+ and PSU's.  This was done in only a few minutes.  After install I did set a static IP and input my pool's but went very smooth.

Below is some pictures of it installed:



4) Running the miner
Was very easy to set up and get running if you are familiar with the AntMiner GUI.  At this point I do have network settings set up with static, and my pool imputed.  I currently will not be trying to find best setup on under clocking, or overclocking as I did not want to break my warranty.  After it runs out I likely will see if I can under clock with and what results are.
 
Below shows the miner actually mining:



5) Conclusion
This is likely the last machine to use this generation of chips.   It does it well so far.  It had no problem running at specs provided, and install of unit was very easy with suggested items.   This is not a miner for everyone with amount used, but if you have an area for mining it is a lot of power that takes up little room for it's speed.   I will continue to run it and see what I think, but so far it is very positive.


5) How to purchase
You can go directly to the Bitmain's website: https://bitmaintech.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B  The batch one is currently sold out.  With news of next gen chips it is hard to say if there is going to be another batch.

Q: Do you need to use all 3 PCIe connectors?
A: I would stick with 3 per hashing board.  They make sure in email, and in a paper in box to tell you to use 3 PCIe per hashing board. You might get buy with it but it would void warranty.  I would say depends on gauge wire and quality of psu.  But to make life easy and in warranty stick with 3. Bitmain has made sure to tell us only use 3 not 2 with this miner in posts at this point.

Q: What version of cgminer is being used?
A: On my miner which is running the stock firmware that it was shipped out with it shows cgminer 4.8.0 being used.

Q: How many amps do I need to run this machine?
A: Bitmain is very specific on the paper sent with miner you will need 16 amps or bigger to run.   This is where you get into variations of installs as there is a few ways to achieve this.

Q: What about the heat?
A: With the metal case and a push/pull fan setup Bitmain did a very good job on making this miner better then the regular S5 on heat.  It still does have heat with the amount of electricity.  But the metal full case with push/pull compared to plastic S5 sides and no top with just push fan is a noticeable difference.

Nice.  Always love your showcase Red velvet layout.  How are these on heat and do they have the S5 (screaming like a banshee) fans?

The biggest thing I noticed about the heat it seems to do a LOT better job then my regular S5 on heat.   With the metal case and fan's on both sides they seemed a lot better.

I will check it tomorrow and see after a day running if still cool.  But my regular S5 puts out a ton of heat, the plus was much less so far close to install.

https://bitcointalk.org/index.php?topic=1152746.220

How is  the noise level? Is it comparable to the SP20 or lot more than it?

Comparable to a few S5s, which are comparable to a few SP20s although a much less annoying quality of noise.

Great guide. It's always nice to see an informative, unbiased guide that gives it to you straight - well done  :)

From your earlier post:

It sounds like you do not have one on hand.  Are you giving advice based on hear-say or do you have one in your possession?  Sometimes it seems that you just like the sound of your own...fingers typing...



Nice review Notlist3d, I agree the red velvet is a nice touch, very sensual :D

Yeah I kinda wished it was closed on top so that you could at least put the power supplies on top of them.  I'm not sure what that would do for the heat but I have very limited space.

Thank you and others for the nice words.   I will tell tell it like it is :). 

So far the unit has preformed on hashing very well.   No problems on it working no X's or other issues.   I will be going later into my mining area to check heat to see if it kept as cool as it was yesterday and try to judge noise level a little better.

It takes a LOT of cables.   I started to mix PSU's and decided to just go with the Bitmain PSU's for a simple install - https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

With now confirmed needs 3 (at least to power as intended) you have to have a PSU with many PCIe connectors.   And unless you want to run a lot of psu's a server psu with many PCIe is just a lot easier.

Also as far as the footprint the miner is so compact even with the 3 PSU's it takes up less room then a S4.  It's amazing how compact this miner really is for the amount of power.  Not that it's working and I am confident in install I could use some ties to hold extra unused PCIe cables to tidy up just a bit.

It would have been a nice touch if the PSU's had a spot to sit but that was not design they went for.  These units are VERY compact and the connect three of them together with a small footprint.   

I am just happy they used metal and 2 fans on each.   With the way they have blades placed and very easy to get to each one you do need to put them somewhere else.  I personally went with the side of miner as it was so small.  But I'm sure a larger scale mine could perfect it more hanging it above the miner with some rigging.

its compact but with the amt of pcie needed +psu's it could be a mess.

Is it possible for you to SSH into the miner & tell me what version of cgminer they are using? I did ask on the Bitmain thread, but am not expecting an official answer anytime soon..... :P

I'd like to see a mainline cgminer in there, but I'm guessing it's their own forked version still?

Thanks  ;)

My extra PCIe cables could be straitened up and it would have a tad more looking clean to it.    One thing you have to remember is it is using a LOT of power in a small space.  3436 watts is a lot of power to be used in the footprint of about 3 S5's as far as area.

Also if you rigged it with PSU hanging above it would be much cleaner look.  I did not do this as I have miners on shelf above it I did not want to put it right under the other miners.   So I really went with functional vs trying to make look pretty.

Its the same fans as on the S5 which is the same as the S4+ which is the same as the S4, of which I've had up to 15 running in the same room at once. So no I don't have an S5+ on hand, yes I can still comment on its noise levels.

I wonder if you could zip tie two of the 2880w PSU's on each side of the miner to make it more tidy and neat.. seems like they can sit on their side right up against the s5+ side and if theres a way to affix them like that would be a good solution to loose psu's all over the place

No problem at all.  It is cgminer 4.8.0 from what mine showed.    I would guess it is their own version did not verify that part.

I don't have the 2880 watt PSU.   So I cannot say on that one.  But on the Bitmain 1600 it is pretty small considering everything I'm sure it could be ziptied or fixed to something.   

Just with my current setup sitting on same shelf was my best option.  If i fixed it above it would be right under an S4.   With sitting beside for me they have a lot of room around the PSU.

Have you done any efficiency testing at different frequencies?

I have not.  It seems to be Bitmain is getting more strict on their warranty.   I decided I will wait the 90 day's most likely until I do.

Or if next gen comes out and I need to underclock.   

I can't imagine there would be any more efficiency to gain from under-clocking than an S5, which is slim to none without undervolting.

As a guess I would assume it has a little bit of possibilities.  But Bitmain gear really always shinned on the amount of overclocking you could do vs the underclock.

I am also still working with my PDU.    I'm hoping to get the networking working on it where I can monitor stats easy on watts used, but it is second hand gear so I'm not even sure network port works.

Nice to see you got one so quick and providing details on units. What is the current power drain on unit on full load working and chugging away at the blockchain. 3436W  reading on the spec is insane for me to run a unit running fully each day would brake about £10 per day to run it, so I doubt would be cost effective for me running one. Whats your current work out on it in terms of energy from socket etc and use? Have you looked into the power use of it yet?

I can tell it's pulling 15 amps worth of electricity from my PDU which put's it around spec area.   My standard kill-a-watt does not have the same plug as I used on the 240.   So cant use it.

I'm hoping in next couple of day's I can try to get PDU's networking to work and hopefully it tells a little more details.  But again it was second hand through ebay and I'm not sure the network plug works on it the PDU from initial test.

I have around 11k watts running in new mining area after this.  And a tad in old area.    But this miner will use every bit of the power the say on specs.  Bitmain say's you need 16 amp to run miner and I would agree with this.  You could do it from two 110's but I went with 240 volt 30 amp which I am very happy with currently.   Needless to say I think my electricity company loves me.

wow at 11k of energy being used and indeed no doubt your energy company is loving you no doubt about that. Hat to see your energy bills at the end of the year what put into it. Just hope you got a good rate off them and are succeeding in paying energy and making some coin at the end of the day too. Would love to have more equipment but stopped mining since the days of S1 and gave up. Maybe if the new miners such as the S5+ come down in price and BTC price go up ill be in with a chance at owning one. Till that happens am sticking to trading or buying coins and maybe look into cloud mining in the future. Loving the work put into what your doing sure does give everyone an insight as to what look like and whats what with them :)

Thank you for the kind words.  I enjoy tinkering with electronics and computers.  And really enjoy documenting and playing with miners.

Even with one miner down currently I'm hitting around 13.4K total between two areas.  Eventually I will part with some of them and sell a few miners, but I have not reached that point yet.   I am lucky that I live on a true farm (like crop and cattle) and power company is use to seeing jumps.   

Went out and checked it is a mild day around 80 F.   The S5+ is still doing a much better job getting rid of heat then the regular S5.  So I'm calling it a sucess on dealing with heat compared to regular S5 since it has ran for around 20 hours at this point.  As far as noise my mining area is very noisy so not a issue for me.  But it is loud enough you would not want to put it in an area you want quiet.

If its anything like the S5 then graph of power consumption was almost perfectly linear vs frequency, and efficiency remained constant within the range of the chips (both up and down).

I would agree it will be pretty close.  They never had the avalon/sp gear adjustment on over/under clock effecting efficiency in big chunks.

I do think it could be overclocked though and get even more hash.  I personally did not do it as I don't want to break my 90 day warranty.

down the road you can try a 10 volt freq 200 underclock.

I will help you get to 10 volts to do it.

Thank you!  Down the road I do plan on playing with it more.  But with paper/email it really seems bitmain is getting harder on warranty.  So I'm going to ride out the warranty in default specs.

The one thing I am surprised just going over my notes is that they did not sell a 1 module unit.   Each module is 100 percent the same.  The only difference is one of the three had the controller put on it.  So they easily could have don't like a S5+ one module, or three module with no additional cost other then more controller boards.

I would have purchased a 1/3 size unit. I do think this would have been nice gear.

I'll bet this was a "Marketing decision" and not a technical one. Who knows, after they have gotten all the folks that will pay for a 3-module version, they could start marketing a 1-module version . Of course the BM1385 and S7 might render that possibility moot. Just speculation on my part.

If marketing includes market appetite then probably yeah. People that complain about a 10btc S5+ will complain harder about a 4btc S5++.

Also put yourself in Bitmain's shoes. If you could sell (and in turn ship) 1000 units vs 3000 units at roughly the same margins, and you firmly believed that you would sell out either way, you choose the one with less logistics involved. It's hard to call any of their decisions poorly made when they sell out of pretty much everything they make, even if those decisions aren't 100% to our liking.

I don't disagree it was a business decision.  They knew 3 worked good and in a very surprisingly small box approx 3 S5's.   And it allowed them to use a LOT of chips.

We don't know for sure this is likely the only production run of this mine, unless they have time to squeeze more before next gen.   But I hope next gen what ever it is has more design like the S5+ then the S5.  The metal casing and push/pull fans honestly are worth the extra cost.   

The miner has ran for over a day and ran perfect so far.

that's really nice review of S5+,
i'm expecting it by next Sunday and looking forward to ask you a few questions in order to make sure that i'm on the right track.

- do i need to make any hardware changes on it before i startup the miner ?
- what's the best option for the pool? setup 3 pools or choose the best one ( which is effective ?)
- do you think that S5+ is the best miner to start a mining farm or should i use S5 as a stable tested miner ?

Thanks.

As far as hardware changes it depends on your setup.  You will need the proper amount of electricity to run it (16 Amps).  I personally did this with a 240 30 amp breaker connected to a PDU and then the recommended bitmain server PSU's being used.

All depends it is honestly personal preference.  Some will say support one of the smaller pools.  I personally have antpool as my main as PPS is lower rate then f2 pool.    But some like to miner other way's where luck has a factor in it.  So not really a wrong pool in most cases just a personal preference.

The S5+ is a great miner as far as small footprint and a lot of power it is also more efficient the the regular S5.  I would say it is easy to install if you have the electricity planned out.  Speaking as far as install it's same general GUI on S5+ or S5.  Either way as far as miner settings its really the same on setup from GUI.   Biggest difference is knowing your electricity setup, if you can do this yes very good for any one.

Tested. S5 + works with  S5 18 pin controller board.

Thanks for sharing the info!  It really is a great miner I'm loving i so far not a single problem which is nice to say the least.

What is the DB from 1 meter @notlist3d?

Btw, great guide notlist3d, If I wasn't savinig my coins for s7, I would definetly buy one.

I am definetly looking forward to oc tests, since we were all running s5s around 60 degrees. But the temperatures from the screenshots notlist3d provided seems to be very good, so freq can increase without heat problems, as it seems. Also I noticed fans are working at 4000 rpm, so they can also go 5000 rpm and heat would be avoided.

It's in a mining room so I can't get a accurate DB I appolgize.  It is not quiet though.   Just a lot of other miners and fan's so hard to get a good db reading.

Biggest difference between is with less heat.  It seems to keep much cooler then the very hot S5.

Well almost 3 days and still not a single issue.  I have not had to power cycle it.  It just keeps running great as far as spec.   I'm giving it pretty high marks so far.  Below shows it running for almost 3 days no X's or other issues.

That could be awesome! I wish bitmain work on something like that with the new chips.  ;D

3th and something around 650-700 watt dream!

Interesting for running S5+ boards on S5 controller.

I suppose this also mean you could run some salvaged S5+ blades on S5 controllers later on. That could come in handy.

I hope they keep this design for next small version.   I still like the S4 having it all in one box, if they did that with more density would be great.

But this way of linking smaller miners really does work great.  I'm sure it would cost a few extra dollars to make the controller this nice, but it's a option I would pay for to be able to combine smaller miners hash rates.  And the 3 hashing blades per so far has worked great.

Well first good test of what happens when something goes wrong.  My networking to my mining area went down it's middle of night here.   Quick look at all the networking no quick fix. 

The miner looked fine I was worried without internet if it had problems as some S5's did.  But nothing visibly wrong at all.   So turned it off just to be safe with no networking.  I will be fixing it early in a few hours on what ever network problem I have into mining area.

With S5+ controller I can run
4½ x Antminer S5 .
That's perfect, for my  water cooled S5 miner with 6 blades, which is currently with two controllers.


Today I have a 3 from  S5+ separated  block with different controller.  Three small "Dream Boxes"

I put them mine here
https://www.nicehash.com/?p=miners&addr=1N6av3woss8VGtb1b9cNwpkbmzCNRw7Xr8&a=1&l=1

and leave for 24 hours.
the frequency is 362.5

You can compare with one S5+
https://www.nicehash.com/?p=miners&addr=1NastyFRkeUTmMdbMmzggDVTQA6r3ibUoX&a=1&l=1

Very cool thanks for sharing your results.   It's pretty sweet that it's doing all that.

Almost makes you want to get the controller if you have a regular S5's makes it very nice to have all on one controller and set them all at once.

Good news from  this font my miner was without internet/network for 30 minutes or so last night before I just unplugged it.  No damage no issues no bad things that people experienced from S5 did I run into.

Today I was able to find the cause of problem was new router needed reset.   Which is weird as router seemed fine, but that was the fix.   I recently got 1000 Mbps internet connection upgrade so a few different components when that happened.

But after fixing network connectivity let blades boot up then controller and worked like a charm.  It is running right now no issues now that network problem is sorted out.

That is great to hear. I have been concerned about such and started making a list of items to (have my friend) check. This is at the top of the list.

I am also making a list of items to run up the flagpole at the BITMAIN support desk. If you or anyone have any questions maybe we can make a consolidated list and I will volunteer to submit them together since I plan to get some answers to a few of my own items.

Thanks for sharing your experiences. It is a big help to all owners and 'friends of owners' to the S5+.

VirosaGITS
It is great you are sharing your findings and taking steps to show how these may be used. I have some questions I hope you may help with.
If I missed the answers to these items please simply point me to them.

Did you purchase a spare S5+ control board or is the one you are using one which came with an S5+? IF purchased separately could you share a part number, price, or any information regarding the purchase? I would like to have a spare control board since it (is possible) will do double duty as an S5+ and an S5 backup. Could you PM me on this if it isn't something you wish to share publicly? Obviously I hope we don't see 25 people bumrush BITMAIN to purchase a control board. I think a spare is a good idea.

What are your feelings on the S5+ control board being a central point of failure for 4 - 5 S5 miners? You mention running 4.5 S5s with the S5+ control board. I remember seeing a thread with water cooled S5s, I need to do some searching, but can you point me that direction if you have all of the temps, pics, etc documented?

With regards to running the 4.5 S5s using the S5+ control board is the thought you retain the original S5 control boards to use as backups if needed so the only potential 'down' component(s) are the S5+ modules if you have a failure? Or, is it more about having a central location for all I/O. (I am using I/O in this context for electrical and mechanical items along with a central software location.)

Have you used the S5 control boards on the S5+ modules?
Could you share which version of control boards for the S5 and S5+ you are using to perform which task?
For example if using the S5 control board to run S5+ modules it would be great to confirm which version of the S5 control board you are using. Either way it is great to document for future endeavours. I can see people attempting to match things up down the line as I see people doing now for the S3, S3+, etc. I myself am tracking down control board revision information for the S3 and S5. Anything you have will be helpful.

Do you have any pictures showing the S5+ control board connected to multiple S5 units?
I have not investigated the specifics myself, but reading there is a difference in pinouts (something about 16 pin to 18 pin) I wondered if you had to offset the connector somehow, shift to the left or right, or some equivalent to make it run correctly. A picture of this with clear details would be fantastic.


In my humble opinion information and experience are more valuable than post count or trust-rating every day of the week.  
So again, a sincere thank you to both for sharing your findings.
 

I share  again one finding .

You can use new S5 Hash PCB  ( 18 pin connector)   with S5 Control PCB  (16 pin connectors) Need only a 16 pin cable.

do you want to sell 1 of them?

I want to try to down clock it   using 3 of these

http://www.amazon.com/gp/product/B00C9UUFHC?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00

I am thinking I can get it as low as 310 watts at 1th

 It is not possible. Transformer High Power 15A .

Well it definitely passed the no networking/internet test.  Still getting it all kinda setup with my faster internet.  Was at least 30 minutes without like I said earlier.

No issues during that 30 minutes.  And after I fixed it up no issues at all today.  Working great still a very solid miner.

3 of them from the same psu should work

send 110 watts to each blade .

there are  3 blades in ⅓ of the s-5+

Managed to purchase one! :o

This is probably a scam!

Note that the text of the link above says "bitmaintech.com", but the actual domain is "bitmaintech.co". Looks like "bitmaintech.co" was registered on Friday August 21st, 2015.

The main bitmaintech.com site says nothing about batch 2.

The only thing that you've managed was to be scammed..

yeah whoever "purchased" these were more than likely scammed, it seems pretty obvious at this point

Today I received my last S5+ and I feel well like scammed from BITMAIN.
1. No aluminium body.
2. one totally broken fan.

Interesting, can you please post pictures? They will most probably release new batch soon and people will buy it. Broken fan feels like its been used for a while, is there actually a way to learn the age of the miner (through firmware perhaps)?

Yes please take pictures no aluminum body is very surprising.  I don't think they showed a unit without it on S5+ so please share it with us.

Mine is still working great.

Tupsu, man, why don't you post this in s5+ thread? not in a personal thread?

@notlist3d: Too bad that you want to keep the warranty! really wanted to see some underclock and underclock, temps, and kw consumption  ;D

So, buy an S5+, break it up into 3 units, and re-sell?  Is this something we're going to see happening on the used market?  Would be really cool!

It looks like its aluminum but I could be wrong.  Is it the fan you were saying is not aluminum?     But yea hit up bitmain - https://bitmain.zendesk.com/hc/en-us and get a new fan.

Yes on this miner I want to keep warranty in tact.   Chances are I would run on spec so I don't want to ruin warranty to get specs.   If bitmain gave me permission without losing 90 day warranty I would try some other things, but I am not expecting this.

It looks like Tupsu's last S5+ is just missing the aluminum housing around the controller board.  Is that the aluminum missing? Sucks about the fan.  Sure they will probably make good replacing it, but at what cost to downtime?

I can't tell from this angle.   You might be right the wires make it hard to tell, the controller is pretty compact so wires might be covering it up.

I'm sure he will tell us though.   And on downtime normally they don't do anything but I hope they do something for him.  But I doubt it.

It is made of galvanized sheet steel.

Ahh thanks for sharing.  I was looking for plastic did not think of different metal material being used.

You are right they have it on spec as "The S5+ uses an unpainted aluminum casing".   Odd that they would have mistyped that.

Still working great no issues as far the unit.  It handled that night I lost networking out there so solid unit.

All chips are working great no X's.  I am very happy to say the least about this unit.  Below is it currently running:

looks very sexy ;D

I am extremely happy with it.  I was worried about no network issue some had, it showed it mine does not have this from when I lost networking during middle of night.  All hashing blades work to spec not a single X or issue.   So out of 9 blades 0 issues.

I would like to know if everyone who got one is as happy as me.  If they all were such good units.  I have not seen anyone post a defective one yet online, so I'm thinking even if it was a one batch thing it was well done.

Yes, happy customer here, no issues it just keeps hashing. powered with 3x evga 1300's on 115

S5+ is better built as S5.
But only S5+ problem is - broken software .
An S5+ is not working choice - Customize the fan speed percentage.

Customize the fan speed percentage-  works perfectly with S5 controller.

 S5+ single with S5 controller

It appears someone who posted a while back user: Meat was passing out some links that were to fake bitmain site. - https://bitcointalk.org/index.php?topic=1157426.msg12228730#msg12228730  I don't know if he had one in here or not (hopefully not).

But if you did click on a link from him when he was a user I suggest changing bitmain password, or any other site if you use shared passwords (and don't do this).  Also turn on 2 factor on what ever sites you are able to.

Thank  you for sharing all that you have.  I'm glad to see I'm not the only one to think it is better built.

I will agree software is pretty much of S5.  Only thing different is I did have no network connectivity and it did not get warn, or have issues as some S5's say they did.

I wonder if they had better screening or what has caused no one yet atleast to show a screenshot of an issue with hardware.

Last S5+ miners blade  is  broken.

Dang sorry to hear that.  There goes perfect record, make sure to get a ticket in so you can start that RMA.  Hopefully they will just ship you a hashing board.  Please let us know how it turns out on rma and how they treat you.

Man.... with sptech always problems, with c1 problems, with S5+.......
Tupsu, u are the man!

Any word from them? Was not sure with it being Friday if would be able to get good anwser.

How did they treat you so far with RMA?

Aww thats not looking good.

Kinda a overview of past week.  They no longer have a perfect release with no pictures of bad hashing board.   Still waiting to hear how it went for Tupsu on RMA.

The S5+ form factor was kept for the S7 surprising most.  It is a good form factor just surprising for the S7 release.

My personal experience is still great.  I did change pools as one of mine the pool had issues.  But as far as the unit it's still running solid:

Mine certainly does not great.

Tomorrow,  I will shipp return at own expense to  China  2 x S5+ blades. They are heavy.

Their only choice for shipping is offered UPS or EMS. In any case, it is going to cost me more than 50 euro shipping costs.

I am very disappointed with their warranty service.      

Although the miner arrived DOA, they refuse to send me UPS shipping label.

I remember when S1 arrived DOA , they sent in without the hassle UPS shipping label.

The main thing is, the S5+ miners are heavily used. At least a month.Mine was full of black dust from the inside .

The recommendation,  do not buy it. Poor warranty service.

If you need to buy, open immediately a courier. If something is broken, do not accept package.
But even than, Bitmain can take from you miner  return cost.

Sad to hear about your experience.   We definitely had two different experiences.   I can't defend the RMA that does sound like it was a hassle, I wondered how it turned out.

Hopefully they can perfect that part of RMA and shipping damage you had as S7 is the same design.

What type of environment are you running in?   My S5+ showed up very clean and so far appears to not be dusty from the look I had at it.  I went to check after your post.

Sucks about the return hassle.  I can understand that they have to protect themselves against people calling in false claims of broken parts to get spares, but if it arrives DOA they should really do better to help you out.  I wonder if it is because they're really short on the S5+ chips and boards that they make you ship it back to them.

They were very specific on S5+'s they sent a paper with them and an email to account that ordered them.  They basically said things that void warranty and made sure you use 3 PCIe per hashing board.

So I suspect they have you to mail it in to verify all the things they said void warranty, and what damage is from.  It is a business decision I'm sure. 

The biggest thing I was surprised was was he mentioned his looked like it ran a month.   Mine came very clean and did not look dusty in any way.  So not sure if he got unlucky or what happened.

Yeah dust on "new" equipment is always worrisome.  Oddly it's not the first time I heard of dust on new equipment being sold.

This was a miner, came to the old galvanized metal housing.
EDIT.

Shipped today 2 x S5+ blade to China with EMS
1.44kg
costs me 67.10 EURO

Very expensive warranty.

And they still have not sent me a replacement FAN. The recommendation was to use so long- DOMESTIC FAN

It is not cheap.  But not horrible since two blades and they will be shipping 2 blades back.  I hope they get them to you quickly.     

If you think this is bad you should have tried RMA with syscooling on C1 water kits.  I guess I see don't judge as hard after them.  Took syscooling over a month to get me a pump.  And two out of two pumps died.  Both month or longer to get replacement.  So I had to buy pumps on my own to get then quicker.  But that is off topic I guess.

Please let us know time from shipment till when you get replacement once you get them.  Thank you for sharing all you experiences.

Thanks for sharing! I love your projects where you mix or make something.   You did a ton of great watercooling mods to.

The s5+ i got had zero dust in it. I was suprised it was so damn cleanlol

1 thing to note about the warranty is (and i noticed it only when they emailed me the doc the day the miner was set to be delivered):

"3. In some cases, the warranty will be void, but Bitmain can still do repairs at your own expense if requested. The following events will void the warranty:
     a. Customer removes/replaces any components by himself without receiving permission from Bitmain first;
     b. Damage caused by electrical surges, lightning, or inadequate power supply;
     c. Burnt parts on hash boards or chips;
     d. Miner/boards/components damage due to water immersion or corrosion due to wet environment."

Look at letter "c" in the above reasons to void the warranty. "C" shouldnt ever be listed with a miner because when a miner fails it rarely does so without leaving some char mark on and or around the component that failed. Things like chips and smd caps tend to bubble and darken the surrounding areas so by putting this in the "reasons for warranties being void" section makes the warranty pretty much pointless. Ontop of that opening the miner can void the warranty too so just trying to look at the non working board/boards can get u a big old "warranty voided" sticker slapped on ur super expensive purchase. Kinda sucks that they gave me this info only after i made my purchase so i couldnt decide beforehand. Maybe i missed this info when i read the description of the miner.

S5+ not working  hashboard

Warranty has changed GREATLY from the old day's.   If you are going to open it up you really need a ticket on bitmain's site stating you had permission.   Even replacing a fan for less sound ..... void warranty.  I can see why they needed to change it some though.   They make sure you know all of this though it comes with a paper with miner and an email sent to you.

I think C was put there so they have grounds in overclocking and bad PSU's to void.  Some use very cheap PSU's.... and they can burn so makes sense there. 

I still am very happy with my S5+.  No issues and came clean as if not used for long period of time.

Is the hashing board on a C1 part?

Yes. It is on the top of the C1 water block just for the size comparison.

Have you experienced loss of power where the miner then starts back up after the power comes back on. Just wondering if its a problem with the hash boards and and controller all coming back online at the same time? The S7 has the same sequence of powering the hash boards then the controller and wonder what will happen when I power my S7 with 2 PSU's and experience a power outage and it comes back on?

Have had loss of power, loss of network.  It has had no issues with either.  Both caused by a really bad storm luckily only once.

I did go out and turn off the power during the storm so it did not have surges or anything, so I guess it did not have a hard restart.  But network it did fine on.   Power I was a little over protective.

If anyone is able to get a picture of S7 and S5+ side by side for this thread I would appreciate it!

Another  not working S5+  hashboard from my DOA arrived miner with broken FAN.
This time it was from  the other side of miner, not from with broken Fan cube.

Pictured is to see that it is completed witg hashboards from different batches.

I sent it to China on Friday,  57 EUR postage with EMS.


As you can see, at least one radiator is broken off during transport.

Thanks for sharing it is a little odd they would have different versions of the hashing boards.  Were the hashing boards in the module the same?  Or did they put a mix in the same module even?

Thanks again for sharing!

I think  that the last of my S5+  had put together with spare parts and  repaired already before shipping to me.
Total three different set of blades in one miner? It's not normally possible.

And why he came to the old iron sheet housing, not aluminum housing, as
the other two S5+ miners shipped before?

Does sounds like that one had a harder life then the rest before you got it.  I am surprised they shipped with the way it sounds like that module was.

I wish we could see stats.  We now know it was to get rid stock of chips, and this miner did that very well for them.

Here is showing an S5+ when it works properly.  Here is after 14 day's of solid running no issues all chips and boards look good:

There seem to be a software bug in the calculation of hardware errors? Probably not too big of an issue at those clocks but still.

It is hashing fine as far as pool side so I'm not worried on it.  I'm sure there is some error in calculation part of it could be with it running so long, I think most miners don't make it to the 15 day mark without a restart or something to reset clock.

It looks like two heat sinks broke off before it got to you.  Were they loose inside when you opened it up, or did they forget to put them on?

I received today a parcel from China .

Inside were two blades from  S5 +

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.

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'm happy they decided to use them though.  On the regular S5 they went back and forth on if units had heatsinks.   So I think loose is better then none.

But it does seem they need to choose another adhesive for shipment to customers.

And 20 day's up.  If you get a good one it really is a good miner, in my case I have not had to touch it's settings in over 20 day's it keeps on a hashing.


It does show a neg hardware which I still find interesting after it being pointed out.  Makes me wonder if it's equation is off.

Well my power went off from power company (something to do with upgrading line).   My miner made it to almost 25 day's running with no issues.

I really still say it's a solid miner.  Sadly my test of seeing how long it could run without issue power company stopped that.  And I think they are doing it once more this weekend.    Good news S5+ had no issue with power off and came up back fine.

I still am having good luck with my unit.  It has been a week since I lost power for electric company upgrade.  And unit has ran solid ever since then:


Very low amount of hardware error's.  And over a weeks worth of mining.  The interesting thing is no longer does HW errors show a neg number which was impossible.  So maybe it was just a glitch that once or it could have been from running 20+ days without issue.  Guess we will see depending on what this hw error shows in a week or two.

starting to get more and more jealous! i will look for an s5+ for myself just for fun! and hash powaaaa! ;D

Still working great.   I am up to 16 day's.  Something interesting is once again it hit neg HW errors which is impossible.  So something with the math of HW errors goes neg if you run it LONG term without any problems, and have low hw errors.

I really do love this machine.  Hit 30 day's again.  Set it and forget it... that is a nice concept in mining.

That is really impressive, especially given all the problems people reported with the S5.  It's like they brought back the S1 bullet proof-ness for the S5+.  I hope their S7s run as smoothly.

Now if only my electricity was priced such that I could run any of these new machines...  :'(

I don't know if I got lucky or the ones that posted with bad results got un-lucky.  But this is honestly a rock solid rig.  I was worried with all the PCIe cables, and the warnings they give you.

But I have been able to hit a month of running multiple times in this thread.  It really does just keep running, I wish the power company did not turn off power for my reign for upgrades or I likely would have 60 day's on run time without issue.

I would not give my S5+ up right now.  I'm having amazing luck with a lot of hash for 1 miner.   If you get a good one this miner is highly recommended.

And I have hit over 40 day's of running and no issues.  Really is a great miner if you got a  good one very stable:


So far this is my record on the S5+ we will see how much higher I can go :).

How come, with over 7Th and 40 days running (impressive!), your best share is only 592k?  My little 2GH nanofury sticks out perform that in a day!

It could possibly be a display error.  Some stats seem to show up wrong after around day 20.   They just did not intend for this machine to be on this long without down time I don't think.

It's not showing it now but if you have very low hardware errors and can get around 20 day's it's possible to get a negative HW errrors... which is impossible.  So I suspect some of the equations or display of status after long times of running can go wrong.

But I won't complain :).  This miner just keeps on going which makes it easy as I have had to do nothing to help it mine in over a month.

I will second the statement the S5+ has been a solid performer so far.
The hashrate on mine runs 7.64ish.

I have never seen anything which displayed hashrate stay as close as this S7 does.
485x on the dot every second.
