Love the shot's beautiful pictures Dogie.

The pictures make your guides the best!  ;)

Thank you for the review, good pictures and FAQ lists.

Is there a connector on the controller board to connect a WiFi antenna?

No wifi on this controller board.

Do you see buck convertors on the hashing blades?

This is incorrect, the username is "root", password is "admin". This miner uses the same controller type as the S2 S4 and C1 not the S1 and S3.

Fixed

Thank you for the review Dogie

No problem

Hello there,

I'm from Russia and have ordered 1 x ANTMINER S5 BATCH 4.
Now I need some advice from you ...
I have a new out of the box PSU Fractal Design NEWTON R3 80PLUS® Platinum
http://www.fractal-design.com/home/product/power-supplies/newton/newton-r3-600w
and I'll going in anyway to connect it to S5.
Which are the potential minuses I'll get if use the PSU NEWTON R3 with Antminer S5? Please list all if it possible.
Thanks.

That psu is not sufficient for S5.
S5 power consumption is about 660 watt. You need to use at least pure 750 watt psu.

Nicely done! Another beautiful guide.

Looking sweet dogie, nice pictures indeed! Thanks :)

S5 power consumption is 600W at the wall, that means ~500W pre PSU. The PSU is fine for a single S5. The may die prematurely if the quality is not enough, but then you can warranty replace it.

That's why I just dropped another $X,000 on a new setup, I no longer have a bedroom!

Quality of this PSU is 80PLUS® Platinum. However, I do not chase for high hashrate, for me important is stable operation of the S5 with this PSU, may be via underclock, but I don't know how set correctly value.

You can't undervolt with that (or pretty much any) PSU so don't worry about that. You can underclock as normal though.

Of course i can't say more about power consumption since i don't own S5. The 660 watt on wall is from other review (https://bitcointalk.org/index.php?topic=914278.msg10039889#msg10039889).
The exact consumption in 12V rail in unknown.
Maybe in future bitmain and other company can provide this data since we buy psu based on amperage capability.

600W at the wall with a Seasonic 1200W Platinum (240V)

Thanks kano for additional data  :)

50% load on platinum psu. The efficiency about 94%. So the load is about 564 watt on 12V rail.

If using 600 watt psu, that's  93% load. Yes, it's will work, but too much strain on psu.

Heh, I posted this in the wrong thread when I read the question without realising it wasn't the S5 thread :P

I repost it here for those who want to know:

The cgminer config file is:
/config/cgminer.conf

FYI - the S5 uses a BBB like the S2 so it looks the same when you ssh in (root/admin)

So the editable area that survives a reflash and a reboot is /config/

The startup init is /etc/init.d/cgminer.sh

When you ssh in, if you wish to watch cgminer:

TERM=xterm screen -r

Load percent =  wall * efficiency [0 to 1] / capacity

So you actually have 2 unknown variables as load percent varies on efficiency and vice versa. Had to read 6 reviews to find someone who actually characterised it at 240V, as Seasonic don't publish their own graphs.

http://tpucdn.com/reviews/Seasonic/P1200/images/efficiency.jpg

We can estimate from the graph that eff is going to be about 0.935 over our entire range, so lets go with that.

Load percent =  wall * efficiency [0 to 1] / capacity
Load percent = 600 * 0.935 / 1200
Load percent = 47% = 560W = same as yours.

560W is still fine on a 600W PSU as most good brands hold 10% 24/7 capacity in reserve on top of their ratings. Ie the CX750M will do 825W, the RM1000 1100W as long as you're not running in a 40C [50C for RM1000] ambient. Even those that don't rate with a 10% reserve, 560 on 600W is still acceptable for a good brand.

Trialing some new formatting tweaks on this guide. Feedback is appreciated.

1) Section colors changed to more eye friendly ones
2) Line breaks changed to width limited images to prevent them filling the entire page width
3) Code boxes enclosed to prevent them filling the entire page width
4) Page will now display in full at ~1350px width. Can't get it down to 1280 due to too much padding in the forum code. Approximately 24% of users will need to zoom out very slightly.

This might help you https://www.facebook.com/Bitmaintech.Antminer  : face book   and on bit mains  site under batch 3  it says somerthing aobut what you asking  so that PSU should  be fine if your not worried about speeds .

When better power efficiency is needed in the future due to higher network difficulties, you may want to buy some special PSUs 9V DC with more than 10A output, which will allow you to have a 0.2J/GH mining efficiency, but at lower hashing speed.


 but they are right you will need a higher PSU if you plan to over clock i used that as a example nothing more.  just to make a point that it should be ok under clocked by what the tech's  say on bit mains site i think i need to stress that and what others say here before some one take what i said in the wrong light.


I have Six of batch 4 coming  over the next 7 weeks or sooner  two this week and two more the next week then two more maybe three weeks later. selling stuff on E bay .

What PSU do you recommend?

to be honest I'm using what i was using on my S1 and S3 and its looks like they will work just fine with my S5 once i have them .

but i use these

According to the video on face book with the CEO of bit main the ^  should power two S5 with no issues. the ones i linked on amazon I got deals on as used  but were really new and if you know how to you can use the 6 or 7 year warr they come with  no question asked if you have to  . but right now i can't say i would  recommend any thing, waiting for my S5 to come.

according to this https://www.youtube.com/watch?v=Azif7Gditxg there is no WiFi . sadly for you .

Yoshi is not the CEO of Bitmain, its just labelled wrong :P He's very very important in the US though.

The S1 and S3 had a setting in one of the config files where you could set a goal temp for the fans.  Any idea where the S5 might store that setting?  I figure if I can raise the goal temp a bit, I can make them a smidge quieter.

I don't, sorry.

Anybody know - would an S5 run properly if you plugged another fan and two more cards in to it (provided you powered the two additional cards with a sufficient PSU)?

Because the situation is that one of my two S5s came DOA - the top PCB is defective and I'm waiting for a replacement. Worth the risk of plugging the two cards on the broken miner into my working S5?

I wouldn't try it, those cables are also mightly short. By DOA, what do you mean? We can probably get it going again.

hi Dogie, thanks again for your great post. one question, is there some way to implement load balancing? thanks again for your time and considerate reply.

1) SSH to S5, Login root/admin
2) Type "screen -r". Wait for all the messages to go through.
3) Type "P" to enter Pool Management.
4) Type "C" for Change Management Strategy.
5) Select one of the following:  "0"-Failover(default), "1"-Round Robin, "2"-Rotate, "3"-Load Balance, "4"-Balance.
    - Load balance requires quotas to be setup first (via "Q").  Balance uses equal share across configured pools.  Read the cgminer readme files for more detail.
6) Press Enter key to exit Pool Management menu.  Should now be back at main cgminer menu.
7) Exit screen session by issuing "Ctrl-A", "Ctrl-D".  (Hold down Ctrl key, press "a/A", then "d/D".
8 ) Now back at shell prompt.

Modified from MissouriMiner's S4 instructions (https://bitcointalk.org/index.php?topic=796839.msg9331221#msg9331221)

Thanks.  I managed to quiet it down by just swapping out the fan for two b-Gear 120mm fans (http://www.newegg.com/Product/Product.aspx?Item=N82E16835132022) in a push-pull configuration.  Runs at about 71C in a 75F ambient, but at least it keeps the wife happy.

DOA = Dead On Arrival

It's that top chip that you plug the ethernet into. Of the two miners, one works and one doesn't. When the broken chip is being used, the fan doesn't run, it makes little to no noise, and I cannot find it online using my router. But when I remove the "broken" chip and then replace it with the "working" chip from the other miner, it works fine. That's the best I think I can describe the issue (I tried pressing that button to restore it to factory settings, but nothing...)

I am emailing with Yoshi and he's been helpful. He and the team have been providing suggestions, but I either am lacking some technical knowledge or it's beyond immediate repair. I've got an RMA going and sent them the broken chip to have it fixed or replaced.

But if you have any ideas as to what it might have been, I'd be curious to hear as I spent a lot of time troubleshooting  :P

OFC dogie know what DOA mean. What dogie want to know is the symptom? Can you access the configuration page? etc
What is the "top chip" you mean here? Chip is usually refer to single ic or asic.

I think he was referring to the controller board. If the fan wasn't spinning @ 100% it suggests something electrically dead.

To power your new S5 which PSU or PSU's would you use? Why?

Single HX850W? Single HX750W? Single CX750M? Or twin CX600s or twin CX500Ms?

Likely overclock in the future. All PSU's are Corsairs.

thanks all

Single CX750M is the best buy for EU, EVGA 1300W for the US. I would have said the RM1000 if S5s had been just a bit lower power consumption as those things are amazing, but alas its just a bit too much for 2x on an RM1000.

What? I've got a number of Corsair PSU's, looking for reco on what to use out of what I have.

1x HX850 or 1x HX750 Corsairs? Have 3x CX750Ms, believe one will run the C5. Be safe and run two? Or is the completely contrary to power conservation?
Run twin CX600s?

thanks!

Single cx750, hx750 or hx850 will done the job, but if you cont the efficiency then hx850 will give smaller power usage.

Any of them alone will run 1x S5 fine, although you'll need to pair up the CX500Ms to run 1x S5.

Your guides are amazing. Briefly, I'm a guy that just wants computers to work. Bitcoin mining sounded amazing and for sure out of my reach. By looking at machines, then your reviews and setup guides, I learned. Enough to get bold and order some S1's. I actually unboxed machines, paperclipped PSUs, bought extra cables, booted and configured and mined. In addition to losing some money, it was honestly a big confidence booster. Without your guides - clear and concise - I would likely have never tried. So... guides are awesome.... thank you.... you owe me about $2k for getting me into mining. BTC is fine on that. :)

What I'd love to see in guides is what I'm asking here... which PSU is best for the application. Not blowing the miner up, not causing a fire, using plenty of power, and doing it efficiently as reasonably possible. That would require you not only testing miners, but testing them with 101 different PSU's and PSU configs. Likely not possible. I will take the survey and the BTC you owe me, thanks!

Back to my question, again :) Single power over 750 sounds reasonable and doable. Would it make sense to DOUBLE 750s so they aren't overworked/ready for overclocking?
If so, wouldn't double 600w PSUs do the same job as the 750s?

Thanks so much!

I actually do do that with the PSUs, but they're in the "what you need" links. I used to almost always recommend the CX750M, but as power per unit has crept up then I usually recommend the RM1000. Both of these are the stablest, safest PSUs with a strong warranty behind them.

There would be no reason to run 2x 600s / 750s for 1x S5. PSUs are more efficient between roughly 50% and 80% of their max capacity, so running 2 at 250W each would be quite an under utilisation.

Just trying to set up my S5 and the "find your miner" software gives me a "wrong IP format "error. I have put in the WAN IP address from the router setup browser which ends with 188 ( I tried adding a .1 also but that doesn't help) has anyone any clues please?

Thanks

Go to your router configuration page & find the dhcp page. Your miner should be list there.

Thanks Zich,
                  Found the DHCP list in the routers browser under status/diagnostic. Punched that straight into my search browser and there you go into the Antminer setup  and off to work it goes.

I think I'll get some more of these, heaps easier than the early days with GPU's and a 10kw power bill.

Thanks again

Great  :)
Good choice, S5 power consumption is the best comparing to other available miner.

In that box it wants the subnet, ie 192.168.1. Then the next boxes are the range to search on that subnet.

Firstly, thanks for your guides and info Dogie. I end up referencing your stuff when I have an issue, or question about any units I am looking at. (Been lurking for quite awhile)

I have a few r-box 2's running off a SuperNova 1300; going though a Raspberry Pi running cgminer. I did some modifications to anubis and use that as my dashboard, since the miners are all in the basement, and this way I can just popup a webpage to make sure everything is running smoothly.

Here in lies my question.

I just ordered a S5 and another SuperNova 1300 (Which from what I understand can easily run 2 S5's, and maybe 3, if you split the 6pin leads, though I would need to poke at that more, before I try. Has anyone, or does anyone know away to monitor the S5 though something like Anubis, or Minera, or Multiminer?  I would like to have all my miners on 1 sheet of glass, so I can just poke at it when I want to see how they do doing (Temps, has rates, HW errors, etc)

Thanks

An Evga SuperNova 1300 can run 2 S5s, definitely not 5. They've got 8 PCI-Es, as 2 S5s have so you won't have to do any splitting. You can monitor via the webpage, or a third party application like M's miner monitor (https://bitcointalk.org/index.php?topic=596178.0). You should be able to turn on API support on your cgminer running the R-Boxes, so you can also add them into this.

Please consider filling out a quick survey about my guides to help improve them! You'll be entered into a raffle to win 2x $20 vouchers as a thank you.

I'm using two (2) CX500Ms to PSU for S5 since I have couple dozen PSUs leftover from GPU mining to S1 mining days. I bought some new PSUs for C1 but didn't want to bother with cooling system assembly and didn't order C1s. I probably only S5 and retire others in the summer.

Hi, thanks for your guides ? Excellent information.

I have an S5 that has been misbehaving, with hashrate dropping off and temps going down just on blade 1. Eventually I swapped the fan power to the other connector on the top board and it seemed to help. I have had it running using 1 x 750W Seventeam (supposedly coolermasters OEM) 80 plus bronze. I then switched to using two different makes of 500W 80 plus PSU, one on each side, blade one using a corsair. It ran fine for 4 days then dropped hashrate even though all chips show up as fine on the web interface. The temps on blade 1 dropped to 30 though. I have just splashed out on a Corsair AX1200i and plugged into that. My meter shows a max draw of 580.2W on the wall side of the PSU. So far so good, but do you think power could have been the issue ?
Also, I'm hoping I can run two S5s on the AX1200, what do you think ?

thanks again.

1) Can you try and find the exact model of the original PSU please?
2) I wouldn't be surprised if it was power issues with a 'cheaper' PSU, especially now its working fine.
3) 2x S5s on an AX1200 should be fine, AXs are immense. There is always a risk that it may trigger its overload protection as found on some larger PSUs, which will prevent it from turning on at all though, its a bit hit and miss. Potentially another CX750M would be safer and more cost efficient for a second S5.

1)Seventeam ST-750PWL running both blades, then tried a Corsair PSU (CX500M) on one blade and either an Antec 500W or this one pictured below on the other blade.  I'll have to look for the Antec box for the model number, it's quite old but brand new in a box. I got it as a replacement from Antec maybe 10 years ago, never used it.
http://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/2VsAAOSwc3ZUqY5G/$_57.JPG

The S5 is running fine now but it's only been about 5 or 6 hours on the new PSU, so if it lasts a week it will have broken its own record so far ;-)

Thanks for your help :-)

Seventeam ST-750PWL is dual rail psu. Each rail can deliver up to 30A(360watt). Usually 1 rail for pcie & other rail for hdd molex/sata. You can use the psu if you can make modification from molex/sata to pcie.

1) The first PSU is not suitable as it has 2 rails, which typically means you're relying on the PSU to properly load balance. In this case, its claimed each rail can take 30A on its own = 360W. That's really pushing it and likely explains your problems.
The second PSU is also not appropriate as its dual rail, again you're going to be relying on the PSU to load balance well to not exceed its ~200W on each rail.

Ok, thanks.
So ideally I need a 750W or greater PSU with a single 12v rail to power an S5 reliably. Or possibly use 2 molex/PCIe adaptors on one blade. The Seventeam PSU has 3 PCIe leads so I just used them and an adapter for the 4th PCIe. If I had used 2 molex leads with adaptors and 2 PCIe leads I guess it may have worked out better. I'll give the S5 a week or so on the AX1200 to rule out any local issues and then try out the Seventeam again with correct wiring.

Thanks for your help :-)

The problem is people can say its a 750W PSU but internally its really not geared up to be run at that 24/7. Stick to Corsair and you'll be fine.

So i have been really confused over the whole UserID.worker thing please explain to me what the worker part of it is and how do i know what it is can i just pick a random thing so (user.ctsdfcvjygaviyg)?
I hope that wasn't to hard too understand
Thanks,
Zetoid

There's a couple good websites out there that have PSU databases on them if you want to do some research on what's available out there.
http://orionpsudb.com/platforms.html
http://www.realhardtechx.com/index_archivos/Page447.htm

The first one sorts PSUs based on their platform, the second one based on the manufacturer. The second one also lists the OEM.
It can be helpful, as even though a PSU might be a Corsair, Corsair (and most other PSU brands) don't actually make any of their PSUs, and different lines (and even different wattages in the same line) can be made by different OEMs and perform differently.
It is also helpful if you want to shop around. The popular EVGA 1300G2 is made by Superflower, and the platform is the Leadex Gold. If the EVGA is hard to get or more expensive in your area, the actual Superflow unit (http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=367) will work just as well and might be better for you.

UserID = your username on the pool, its what you login to the pool website with
worker = the name YOU give to any miner. It can be whatever you want.

Ie zetoid.AntminerS5_a, zetoid.AntminerS5_b etc

FYI some pool are buggy when handling "special" characters after the initial user delimiter, I've noticed this issue with ghash and antpool where using a "." or "_" after the initial delimiting "." or "_" will cause the pool to either reject the user or simply not show up in the account. This isn't an issue with ckpool based pools however.

Ty :)

any ideas on modding the fans so its more quiet?

Nope.

if you have a molex->fan adapter that provides either 5V or 7V try that.

at 7V the fan is a reasonable volume and can handle stock speeds as long as the temperatures stay <65C.  if its a colder environment, 5V is living-room volume but needs cold air or has to be set a bit below stock speed

Hi Guys,

Can I use the following power supply for two antminers S5 : http://www.fsp-europe.com/aurumpro1200.php

Thanks

Its pushing it a bit close for an unknown quality PSU.

It's one of the best PSUs(fsp stands for Fortron Source Power which is the well known brand Fortron) - what do you mean by unknown :)? Just look at the awards list on the link that I've posted.

My point is if the PSU is 1200W (80 plus gold and stable characteristics) - is it ok to handle 2*590W=1180W(which is supposed to be the power of the two antminers S5) at the regular hash rate without much overcloking ?

People have reported running two non-OCed S5's on a 1200W PSU so you might be fine, though it is pushing it a little close. You'll be running it at 90% or so load 24/7, so just avoid any overclocking.

Capacity wise its fine as its really 2x500W pre PSU, I'm just not intimately familiar with that brand.

They're a pretty major OEM, they make rebranded PSUs for the likes of EVGA, NZXT, Antec, be Quiet, OCZ, etc. For instance, EVGA's G series is the FSP Aurum design.

yeah but try freq 343 for each one. run it for a day or 2.

i had the 1000 watt model. it is decent psu.

freq 343 wiil get you about 1125gh x 2 = 2250gh  if you are in europe and plane 220 volt that psu will have a little more power to spare.

As always I tell people evga 1300 g2 psu's but that is base on usa prices and usa 120 volt power

Beginning to believe that the evga 1300 g2 IS the way to go when powering two S5 home miners. Currently running 1x CX750M each and no excessive heat anywhere, miners running cool, great hashing speed at 350. No plans to change from 350 anytime soon. Not broke = don't fix.

Dogie! Either I'm missing an inside joke about you having no clue re fan swaps for the S5, or I'm somewhat confused and fairly disappointed. Considering the S5 is one of the very top choices today for home mining, and it is roundly agreed that they are loud considering their intended purpose. There are a dozen or so 120mm contenders out there that actually push some air. I don't need them whisper quiet, but surely shaving some db's is within the realm of possibility.

Do you not recommend anything at all no matter what - so as to not interfere with user warranty issues due to modding the fans? Something more sinister like sponsorships colliding?!

Would like to mod fan on S5. Would like to plug it directly into S5's 4pin on top. Don't need silence, but seems like there are 2K rpm fans out there making ~90-100 CFM at 30-40 decibels.

Anyone want to venture into the muck of this question? I'd also like to have spinners (LED's) in the fan just because why not?

thanks all. Dogie this site is my source for 95% all things bitcoin. Buy and sell gear here, trust your word, just want to hear from you on the subject. If there is an unbiased fan comparison somewhere would love to see it.

thanks!

Its a greatly praised PSU that one, but not easily found at sensible prices in the EU and so Corsair remains king over here.



The user who asked has literally just flamed me in another thread, then came in here asking for help. I kindly send him on his way. My personal recommendation is 2x S3 fans if you've got them lying around or my go to is the SP120 Performance editions [Without affiliate] (http://goo.gl/994pId) [With affiliate] (http://goo.gl/aTtqhF). There are also PWM versions if you think you'll need it in the future [Without affiliate] (http://goo.gl/464xEn) [With affiliate] (http://goo.gl/ULI5ny). They're right at the barrier between high performance and not being too annoying and I generally use them on most miners I silence.



If I were doing it on behalf of Bitmain, I'd be telling everyone to overclock and do mods so they don't have warranty costs :P



Fans like the SP120 will plug directly into an S5 and aren't silent but aren't horrific. They're ~2200 rpm with a high static pressure which is required in a situation like this more than just straight 'CFM' ratings. You don't tend to get LEDs on fans like this and above as they usually all go into servers and such like. There is a similar AF120 series which is LED, but isn't suitable for S5s as they're not powerful enough.



Thanks for your kind words.

Thanks for your kind words.

I'm glad you weighed in, was worried,

Tell me about push pull setups, please. Any sense in doing such? Step up to the Noctuna fans? I do like the price on the 120's in the 2 pack.

I'm looking to lower the noise. I don't want to spend money to quiet it down a bit and gain 5-10 degrees while doing so, Everything under 50 degrees now, and I like that, So no need for twisty LEDs that would be fun for about a day.

Also, looks like the S5 has 2x fan 4pin outputs. Would that run 2x the 120's you mentioned? I see fan controllers and all that, don't want to get involved if I don't hae to.

thanks dogie!

also, think i'm picking up a NIB evga 1300g2 supernova gold blah blah. So excited.

Pull > push pull > push but only in a sealed environment like an ASICMiner Cube, or an S3 although that wasn't great. In an open environment, its push pull > push > pull. In this case though, you're going to NEED to run 2 fans in order to maintain enough cooling with slower fans.

I'd still go with the Corsair's, they're the perfect balance of performance and noise. Yes the fans should run straight off the headers, worst case you'll have to use molex adapters and power them from the PSUs.

Just an update on my PSU issues.
I ran the S5 fine on the AX1200i for a week, but wasn't too sure about running two S5s off it. I have an energy meter at the wall and the max wattage for 1 x S5 via the AX1200 has been 610W.

So I've RMAd the AX1200 and gone for an AX760. I have another S5 now, so that is running on a CS750M.

All good so far.

Anybody know what the best difficulty setting is for an S5 ? it seems to like 4k and hate 2k.

Cheers

1024 or 2048 should work well, higher than that and you're just burning shares on discards.

Totally agree on the Corsairs - I have several of the AX760's and they act more like a big battery delivering up to 63 amps on a single rail with less than 7mv of ac ripple !  Plus the modular connectors.  Wish I had the 860's so I could run 3 S5's on 2 PSU's.

Looking for an S5 guide to what all the LED's represent - I've got a new S5 that doesn't light up the red ones on the two ASIC boards and the 4 green ones on the board under the controller have the 3 inside ones lit constantly with only the outer one blinking.

Any clues ?

okay got my S5's in today no SD cards are in the slots

these dont come with SD cards? or did bitmain mess up?

should i put one in?

if so how do i put a image on the SD card i got a few laying around and have download win32 disk imager and the image from bitmain

sorry this confuses me all my other miner have sd cards.

I knew these did not have a top on the case but they dont have a bottom either? WTF!!!!

These are a nightmare to fit into my current exhaust configuration, going to spend all evening making proper cases for these. Seriously bitmain could you go any cheaper? I am not impressed!!!!!

okay think i figured out how to do the image have to read the image first then write it :)
first time i just selected the image from location and pressed write. Now that i pressed read first then write is doing something :)

S5s don't use SD cards, just plug the S5 in.

Thanks dogie I was thinking bitmain messed up :)
So they SD card slot is for restoring things if they go wrong?

Yes, but currently we don't have a solution on how to use it.

I heard that it's enough just to insert a SD card with C1/S4 firmware on it and boot up your S5, then you will need to update a FW to latest (or custom...) version for S5.

That itself doesn't kick the firmware over to following the SD card over the flash memory last I tested. The latest instructions we had for that process don't work.

Hello everyone!Just a newbie miner question i bought an antminer s5 and for psu a corsair rm850 i also bought 2 fans corsair, one sp120 and one af120 and i want to plug them with psu to operate full all time.... my question may sound stupid but i want to ask where i have to plug it as i didnt found any cable for those in corsair psu box.What cables (adaptors) i need to buy to work with my psu?One is 4 pin and the other is 3pin.Any advice will be appreciate it.

Kind Regards,
BTC-Bank.

I am not quite understand of your question. Are you asking about cable from wall to psu or psu to S5?

My appologies i was in hurry..I am asking for what cables/adopters i need from psu to (extra) 2 fans wich one is 3pin and other 4pin wich i will use for antminer s5.  :-) i want to replace the original as it is too loud!

I tried the fan (4pin) direct on s5 but is not stable goes from 1600rpm to 2160 rpm and i want it to work full runing all the time so this is the reason i am looking from psu to fans direct.Thank you for your responce!

Kind Regards,
BTC-Bank.

Ohh, you might need to cut fan wire then connect to molex or you can buy something like this:

Oh thank you @Zich i really appreciate it!I was looking for something like this to show the stores here what i need!

Kind Regards,
BTC-Bank.

Any time dude  :)
By the way, if you had soldering skill, you can buy the connector on electronic supply store & make them your self  :)

I have the skills but i dont wont to mess with it..i will buy it straight for any case. :)

Thank's again for the tip! :)

Kind Regards,

Is there a recommended fan which can easily replace the original fan to reduce noise?

Corsair sp120 high performance + af120 silent for a small test i made was very silent but i don't know how it will work for many hours or if they will be any problems for the s5 as i didnt buy the cable to connect them to psu yet..From my search i think this is the best solution but you can try it in my opinion with 2 sp120 as they are more powerful but silent too, i think it will be much better.

rpm for sp120 and af120 it will be around 3.360

Kind Regards,
BTC-Bank.

Thanks for this.

AF120 is 1650RPM with moderate static pressure, which is too low for an S5. 2 SP120s works in sensible ambients and benefits from taping the heatsinks closed (top and bottom). Its going to run hotter than stock (60-65) but thats fine and its the closest you can get to a silent S5.



No problem, let us know if you need any help.

Is there also an option to simply replace the one existing fan?

Yes, there are lots of variants of Delta 120x38mm fans, at varying cost and specifications (one being the Delta FFB1212VHE). I can't say any of them is drastically quieter though.

Thank you for the detailed analysis @dogie i think will buy one more sp120 before installed it to follow your advice and i will use a third fan also in front of it to reduce temperature.

Kind Regards,
BTC-Bank.

With the open top/bottom design is it better to put these on a bakers rack style open air shelf, or a solid shelf to allow some air-pattern-control?

My miners are on a solid steel work cart so wondering if they will do well on the steel, or if I should get a riser with open slats?

I've always used open shelves, but then again I have a mishmash of different gear. You can get the effect of a solid shelf by taping up the top and bottom of the heatsink, but thats only 2C or so on the stock fan.

If I may ask a follow up question. How would the Scythe Grand Flex PWM compare to the SP120's? On paper they spin up to the same RPM, similar dBA, but the CFM and Static pressure is much higher on the Grand Flex model. Has anyone tried this on the S5?

I'm still waiting for my s5, but I am trying to get my research done now because noise will be an issue. I have 8 of the Grand Flex fans in the box and it would be nice knowing I don't have to purchase new fans. My goal will be to get the S5 as close to S3 noise levels as possible without sacrificing much cooling.

It doesn't make a lot of sense to me, they're claiming all 3 statistics are better with no tradeoff, at the same RPM. Still, if it works it works.

Ok just to give an update i didn't bought a cable to connect it direct to psu yet but i bought as i our friend here @Dogie suggest another corsair sp120 high performance which are four pin and i have already plug them direct on the s5 for the last 24 hours, the loud results are amazing!!!! It sounds like my computer nothing more and now i can have it in my room.The rpm for these two is fan 1: 2040 and fan 2: 2160 (i dont know exactly why they run different as they both are the same) i have underclock it at 312.5M, the GH/S are around 1100 to 1200 , the temp is mostly stable at 69 and 70 it make some up and downs between 68 to 71 but i am very pleased with the sound if i make any other changes i will let you know.  8)

Thank you @Dogie.

Kind Regards,
BTC-Bank.

No problem. I think its hard coded into the firmware to have the front fan lower as it was the same on S3s.

Thank you again for the tip @dogie do you believe that if i connect them direct to the psu it will work full?Of Course the 120 more rpm is not that big deal.. and if it will help or be greater for the miner also( if it is connected direct to psu) i just asking from curiosity? As you are more experience with mining do you think that the temp are too high because many may read this post and think to change it also.

 :)

Kind Regards,
BTC-Bank.

Yes no problem with connecting direct to the PSU is no problem, won't really change anything. Temps are fine, don't worry.

I really like that sound the previous was very noise for me which i want to have it in my room anyway thank you again @dogie and all of you i really appreciate your help on that.

Kind Regards,
BTC-Bank.

Could I use two PSU to feed one S5?

I have one thermaltake of 750W and a Corsair of 750W both bronce certified.

My understanding is that this would be fine so long as you use one psu per card.

Can you undervolt s5s still by using a less then 12volt psu? If so can you still under/overclock? What would I need to do?

That's correct, as long as each PSU is appropriately powerful enough to power one blade, you can use a pair of PSUs to power a blade each.

Hello, How much amps do each blade needs?

I have a CX750 (750w, single rail 62A @ +12V)Corsair PSU. It has two PCIe connector.
I wonder if I could run a S5 with this PSU.
tia

Yes you can, about 300W per blade.

Does anyone happen to know how can I set the timezone for S5 ? It seems Bitmain cut this functionality comparing to S3.
I've been looking into how to set the time correctly on my S5, and in the process discovered a few details about time zones on Angstrom linux which they are using. By default, a basic Angstrom image doesn't include data specifying time zones, so will default to UTC time. To specify a time zone:
Install the timezone data package:
Look in /usr/share/zoneinfo to find the appropriate zone
create a symbolic link to this file from /etc/localtime
restart
With the correct timezone set, you can now use NTP to automatically set the correct date and time:
The interesting thing is that neither of these commands worked in S5 console.
1. tzdata package does not exist in 'opkg list' at all
2. location /etc/localtime does not exist
3. ntpdate pool.ntp.org gives 'the NTP socket is in use, exiting' on execute

Any ideas ?

If you've got access to the config then we can work with that. Can you upload a screenshot of the status page please?

  this heatsink that cut only one the length, Is the problem ?

my s3 have cut only one the lenght heatsink  .



http://www.picz.ge/img/s3/1504/11/4/4dc7b0f1c20f.jpg


help me.

Don't understand what you're asking, sorry.

what is ?

http://www.picz.ge/img/s2/1504/12/c/c823585857ec.jpg

i'm interested , this Aluminiumis necessary ? my s3 Missing one piece

Almost always, yes.

why ?

what is ?

what do i ? One missing

With one missing it might not be a huge deal.  But it makes me think your miner took a huge hit.    Breaking the heatsink is not easy.

You might want to check for other damage, see if it still works. Before turning on make sure heatsink is still secure.  You might have to deal with seller if part's are falling off.

*Also this is in another thread no need for double post.  Also this is in S5 forum and it is a S3.   I suggest sticking with your thread you made.

i that touch Aluminium  after this aluminum begin Movement

does anyone here know relation between bitmain-voltage and bitmain-freq?
the original is :
"bitmain-freq" : "3:350:0d82", -> what is 3? 350 is frequency, what is 0d82?
"bitmain-voltage" : "0725" -> hexadecimal? if 0725 is hex, so 1829 in decimal?

Hi,
need some advice here.

I've recently, over the weekend , got hold of an antminer s5. I'm using a thermaltake 730W psu with 2 separate railings for the 6 pin connectors. and i've made sure i connect a single blade to one  railing.

the issue is, i cant seem to get a decent hash rate. im averaging something below 50ghash . which doesnt make sense.  my other miners are on slush pools and im aware that i need to set the worker diff level in order for the pool to assign the work correctly , right ? so that works well for my s4 . but when i set the worker to 1024 , i cant a very low hash rate. i tried leaving it blank as well so that the pool can identify and assign work accordingly. that doesnt seem to help. i've also tried btcguild . that still gives the same results. i tried searching the forum for anyone with similar issues, but so far, cant find any.

any ideas, or advice ?

Hey Dogie,

Can you put on your guide hardware error tolerances. I've done some adjustments and have been seeing errors in the .0045 percent range. I know before you told me what the limit was for concern but it is buried deep in another thread. I think this tolerance would be helpful for some.

Thanks!

Hello Mr Dogie, where can I check the relation btw frec and amp/w consumed?

I know I can change the frecuency of each blade but I am trying to use a 750W PSU to feed both blades.

I wonder what's the optimal configuration to be used with that PSU

tia

I can't seem to find it there is a nice chart with S4, S5, and C1 frequency and watts used.

But no matter what 750 watts is more then any frequency you will be using on a S5.

the problem is that my 750w PSU has 3 PCIe 12v @ 20 a.

I can only connect two PCIe to the S5. I am looking for the optimal S5 UC

Its not far off linear, you can stick with that. You can assume 600W @ the wall @ stock frequency and work from there.

My miner Beeps after running 24 hours straight. I know that it means something is wrong yet I really want to disable this loud noise as it acts an alarm clock sound and wakes me up.

The settings to uncheck it in the general configurations don't seem to always hold. A week goes by and I find it checked again. when I enable Minerlink it also gets checked again. Turning minerlink on also doesn't hold.

where is the beeper on the S5. Bitmain maybe needs to look into another way to disable this beeper.

The beeper signifies no pool and / or internet connection, ie its not mining. You are correct that certain actions in the software will retick the box, and sometimes the setting won't stick at all.

I don't have a good picture of it, so you'll have to look from here (http://www.dogiecoin.com/bitmain-antminer-s5---360-degree-view.html). Its hiding under the BBB towards on fan side of the controller, and the opposite side to the fan cable. Its a black cylinder. If you screw one of the side panel screws into it it will silence and / or destroy the beeper.

Yikes - be nice to those little piezo buzzers :)  Try a piece of tape first.  Depending on construction, it will either practically silence it, make it louder (instant regret), and/or shift its pitch.

I guess if anybody should know, it's you, but I'm surprised that you can't disable it in software/firmware.

If you're very careful you can screw it in such that it only just touches the element which will stop it moving but *should* be reversible. The screws are the perfect diameter such that they thread themselves through the hold and only crack the plastic cosmetically.

Hello Dogie, I love your work with these guides...

Do you have a CLI command's guide to check status and / or change the S5's configuration?

tia

Do you mean by putty? If you want something to monitor in bulk you can use M's miner monitor.

I mean using ssh through putty.
The CLI commands in a Antminer console.

You can use cgminer-api command.

Technically you only need to do
the "./" part is unnecessary since the cgminer-api binary is already in path.

Hello Everyone. Somewhat new to mining and the S5 but I am hooked. I bought a second hand unit a few weeks ago and got it set up just fine. I got 2 more second hand units today and one of them set up just fine. The other one won't connect by ethernet. The lights to the side of the port have a dim Red light on but I cannot find what that error might mean. The fans turn on, the green led's on the top board itself are on, and the red led on the top board is on. However the red lights on each hashing blade are off. I did try changing ethernet cables, tried swapping power supplies, and tried resetting the miner.

Any suggestions as to what could be wrong? They shipped as if they were packed well, no damage to the box. I had the former owner send me a screen shot of them hashing (could be faked i suppose) and they were going fine.

What was his network configuration, DHCP or static? All the white ribbon-esque cables look secure?

Thanks for the quick response Dogie.

Yes all the cables look secure. I believe all the miners are on DHCP right now. Again my 1st and 2nd miners are going fine. This one just the fan's boot up, can not get to the control panel to get into any settings it is not connecting to the network.

http://i296.photobucket.com/albums/mm187/speedychef1/s5-3_zpsnvg9ci7d.jpg

the 4 green LED's on the top board are all solid.

Thanks. Quickest way to debug this is to unscrew the 4 black screws holding the controller + adapter down, and swap that with one of the working S5s. Put the non working one on one of the working S5s and see if the problem moves or stays. Then we'll know if its hashing boards / power, or controller.

Thanks. Looks like it is the controller. Swapped it over and the unit that wasn't working is, and the unit that was working isn't and displaying the same lights/issues.

Is there anything that can be done to repair it or does it need to just be replaced?

If you've held the reset button and that hasn't worked, then you can try another quick swap. Swap the Beaglebone Blacks off the controller boards and see if the problem moves again. Then we'll know if its the controller board or the BBB which can be replaced locally. Although for both you'll have to get in touch for a repair or send it back to your seller.

Ok still a noob, I assume that is the black card? any hidden screws or just pull up?

The beagle bone black is the "black card" that controls the S5.

I don't believe it is screwed down if i remember right.   I think it's just on the  pins.   You would see a screw in one of the holes if it is.

Thanks again for the Help Dogie. It is the BBB (which is not held down by a screw but it is easier to remove the board and separate it away from the machine).

Okay, so you have the options of contacting Bitmain if its in warranty, Bitmain if its not and you want to pay, your seller to send it back or to get another one locally.

Dogie,

I see some people only connect two PCI-E's to the S5. Is there harm in doing this?

thanks,

Rtt

No harm but if you were overclocking it will need the 4 PCI-e possibly.  All depends on frequency.

Yup, and depends on the AWG of your PSU cabling. 2 PCI-E is only possible on TWO cable rails, and only recommended on 16AWG.

I have an issues with one of my new S5's. The machine powers up and it looks like the network adapter is working but the green blinking light that shows its working doesn't blink like the others. Is it a simple fix just to hit the button to return it to stock setting to get this working again? I am not in the same location of my machines so its a pain in the ass to go back to reset machine. Like I said, it powers up, the fan spins but it doesn't seem to be pulling an IP address. The machine was working fine then just stopped on day. Thanks

It's hard to say.  It could be a network problem.  If you do a reset that would allow you to know it's going to be at default IP.  And you can connect to it. 

With others working in same setup that makes me think you have decent PSU's, and network working in general.   It will be a pain but a reset is not a bad idea to try.

If you can't connect to it or find it, then you're going to have to reset it. If the controller has died then that may need replacing although its reasonably rare that it will die in situ. Usually they arrive DOA after shipping.

And do remember that "default" IP on an S5 is actually DHCP'ed, so it could pop up anywhere.

Thanks for the help. The reset button solved it. It happened to a second miner since my post. I reset them both from the button on the front and they are fine for the last 2 hours. I think maybe I had all the miners too close, so I spread them out to help cool better

Hi guys

I just won this free Antminer S5 at another forum, and I'm really a newbie in all the mining stuff.

I just wanna make sure this one is alright:
http://www.amazon.com/Corsair-Modular-Bronze-ATX12V-EPS12V/dp/B00ALK3KEM/ref=sr_1_1?ie=UTF8&qid=1433066697&sr=8-1&keywords=Corsair+CX+Series+750+Watt+ATX%2FEPS+Modular+80+PLUS+Bronze+ATX12V%2FEPS12V+744+Power+Supply+CX750M (http://www.amazon.com/Corsair-Modular-Bronze-ATX12V-EPS12V/dp/B00ALK3KEM/ref=sr_1_1?ie=UTF8&qid=1433066697&sr=8-1&keywords=Corsair+CX+Series+750+Watt+ATX%2FEPS+Modular+80+PLUS+Bronze+ATX12V%2FEPS12V+744+Power+Supply+CX750M)

Because on Amazon it looks like it only has 2 PCI-e connectors? And we need 4 for the S5 right?

I hope you can help me with this...

Thanks in advance.

Congratz!  Where did you win it?

Yes two PCI-e will work fine.   If you were to overclock it you would possibly need four.

Thanks for clearing this out, but I'm a little confused now. 2 PCI-e connectors is fine? On Bitmain they say: "There are 4 PCI-e connectors for +12V DC input and all four are required for use."

Anyway i won it on https://allcryptotalk.com/ (https://allcryptotalk.com/), it's a very small forum compared to this one, but it's starting to grow, and they organize raffles ocasionally.

Oh looks like it does have 4PCI-e connectors, but it seems like on amazon it says it has only 2 :/

http://www.corsair.com/en/cx-series-cx750m-modular-atx-power-supply-750-watt-80-plus-bronze-certified-modular-psu (http://www.corsair.com/en/cx-series-cx750m-modular-atx-power-supply-750-watt-80-plus-bronze-certified-modular-psu)

It's not so much the amount pcie connectors but the number of cables.  If it has 2 cables with 2 each since electricity limitations. Then it's really like having 2 total.

With Power Consumption: 590 W (at the wall) 2 can do it.  You need to plug one in each blade.  And it will possibly make it where you cannot overclock depending on frequency.

Ok, I'll order this one then, thanks for the information! Definetly check out AllCryptoTalk :D

Not a problem congratz on winning.  Sorry on my last post i typed it quickly and it did not sound good.

I had to reread it and type parts over. I heard a miner alarm setting off and had my mind on it.

Happy Mining!

Yes its 4, the Amazon listing has been bugged for a loooong time. Definitely 4 on the CX750M over 2 cable rails.

Great!

Hello guys.
I have one question regarding the PSU for the S5 cause I've been looking around on online shops here in my country and most PSUs come with 6+2 PCI-E pins and the S5 has only 6 pins PCI-E. Enlarging the pictures of PSUs and the S5 to see if the 6 pins plug can go into the 6+2 plug of the PSU noticed that the round and square pins differ. Is there any adapter from 6+2 pins plug to 6 pins plug?
The PSUs I've been looking for are 750W, one 12V rail, at least 4 PCI-E plugs (but 6+2 pins plug only) and gold standard.
Also in terms of productivity for those using this machine... How long does it take for this machine to make 1 BTC? I'm asking this question because I want to make some calculations according to energy costs to see if it worth to use it at home or in a data center.
Thanks!

Some Power Supplies are Modular. and Some are not.  You are probably looking at the Socket on a Modular Power Supply ..
The Socket on the PSU is for the peripheral Cables that come with the Power supply.
In either case the cables that come with the Modular Style Power supply are marked one end says PCI-E ( that will plug into the Antminer) the other end will plug into the Appropriate socket on the Power Supply

The +2 side of the PCI-E plug is just left hanging .. some cable manufacturers have it connected as an 8 pin connector but you should see a break point or separator.
some PCI-E cards are 6 pin and some are 8 pin. so the cables come universal.

Dont Plug the CPU cable to the antminer.. make sure it says PCI-E on the plug end.

Antminers Use the 6-Pin portion of the cable.

here is a picture.. the Yellow arrow points to the +2 part of the cable that is NOT Attached to anything... you only attach the 6 pin part of the cable.

https://i.imgur.com/aZur9ls.jpg

 

One antminer S5 will take approx 80 days to make 1 BTC at current difficulty
it will cost approximately $1.44 per day in US dollars @ .10 cents per Kwh
So that 1 BTC will take approximately $115.20 worth of electricity to make.

Hope that helps

Thank you for the info. That helps alot.

Now one more question... a friend of mine suggested that he would buy one as well and we should connect them both over my place to use the same IP address... Now having 2 machines connected at the same pool from the same IP address will work the same as USB ones that are connected over a USB hub? I mean will their hash rate multiply some how or split the work between them so that they finish faster?

What brand/model is the psu?  You might check and see if it's 4 seperate cables, and not two cables with 2 adapters on each.   Nubminer is right that the 6 pins are all that is used.    

As far as how long here is my favorite ROI calculator - https://bitcoinwisdom.com/bitcoin/difficulty .  It varies since difficulty changes no one can give you an exact anwser on timeline to get to 1 BTC.



You can have multiple machines but they will need diferent IP's they cannot share IP's.   As far as doing it you will be connected to a pool and use different pool worker names.   The S5 has a controller board on it that does all the work it does not use a usb hub to mine.  Having more would just give you more hashing speed.

They are pretty simple to be honest you log in and set it up to mine.   After that you only  use the PC to check on it.  The S5 mines without usb/computer being used.

when you connect them to your router or switch they will both acquire an IP address from your router... you then configure them and point them to the pool of your choice..
they will both work independent from each other but if they are pointed to the same pool then yes they will produce twice the amount to the same account

once you get one and start configuring it ... all will make sense

If you have not bought these already then you may want to do a little research.
Look at the cost of everything. You probably will not see a Return On Investment (ROI) at todays difficulty it would take 271 days of uninterrupted hashing to make your first dollar in profit after all costs and that is at the price of Bitcoin today.

but since the Difficulty changes every few days.. and the cost of electricity is also unstable and the price of bitcoin is not really stable either.. you may never really see any profit.

don't get me wrong it is still possible that things may improve in the price of bitcoin and you could make a profit.. but at least consider all options.

First thing... the power source is the one recommended in the tutorial Corsair CX750M @750W. In online shops here this PSU has 4 PCI-E plugs with 6+2 pins and from the pictures I've seen there are 4 separate cables... that's why I asked cause was confusing. Now I understand what I have to do if I'll go this way.
Secondly... I totally get the idea of independence. It doesn't work like the ones on USB but having more machines will each produce the same amount in the same time.
But for the time being I'll reconsider the whole concept of mining, cause from what I see you must have powerful machines of over 2TH that can actually produce some profit. The S5 is no longer powerful enough at actual difficulty rate.
I was also looking for more powerful machines like S4+ but they are very expensive and to make it count one should have at least 2 of those. Also looked for second hand ones(S4+) here in my country but they are sold for the price of a new one which doesn't make sense.
So I'll take my time to think it over.
Thank you guys. You've been very helpful.

It is easy to get sucked into looking at looking at number of TH, but depending on electricity price the more efficient as far as electricity might be a bigger deal.  You don't have to start huge. Nice thing is you can always start with a S5 and add more if you want to.

Both the S5 and S4+ have their own advantages.  One thing to keep in mind with S4+ is the needing of (205V - 264V AC).  So if you have 120 not really the one for you.  You can get 220/240 installed though, I have done it in my miner area. 

In my eyes either one you mentioned is a nice way to get into mining.

Just to clarify: Bitcoin mining difficulty adjusts after every 2016 blocks. That's supposed to take 14 days. If those 2016 blocks are mined in less than 14 days, then difficulty will increase to try and do the next 2016 blocks in 14 days. If the 2016 blocks take longer than 14 days, then difficulty will decrease, again to bring the next 2016 blocks in right at 14 days.

While it may feel like it's "every few days", it's actually block count based and not time based. If you scroll down a bit on the following page, you can see some past difficulty adjustments and such. Makes for interesting context.

https://bitcoinwisdom.com/bitcoin/difficulty

yea I was not meaning to imply that in 3 days it would change... sorry if that was misleading.. however I think at the date and time of his questions... and given the expected difficulty the price of bitcoin the rising price of electricity.. (going into summer always changes price bracket) and also the new 16 nm chips and talks of the 14nm ,   any new purchase today will probably never pay for itself.. just not the right time...  timing is everything.

just one guys opinion.  That said, I will still buy a few more if the price was right... but knowing they will be obsolete soon makes me cautious

Dogie, any idea why bitmain raised his price to $360?  Besides the obvious more money?

No idea, but its only $20. Probably an adjustment for a cost increase somewhere.

That still adds $.017/gh to an already high $/gh.  But I know where you are coming from.  Hopefully we'll see some coupons then.

Maybe so Bitmain can have a "Sale" on S5's when the S7 comes out, and they can make the price look better?

Maybe Bitmain wants to get the maximum amount from the S5's they can build from ASIC parts already ordered?

Maybe because there isn't anybody else making a "ready to ship" miner at this time?

Maybe because they're running low and S7 is still some way out. Or maybe unicorns, we're just guessing here :P

I was waiting that they lower prices (I bought for ~320 USD months ago) but since they raised them I am afraid that I have to wait a bit longer.
Not interested in buying overpriced hardware seeing the next generation coming out just when old hardware arrives...

I received my S5 on Thursday. Plugged it in and board one was DOA, shows all dashes.  Followed some guides from the internet could not revive the board. I then contacted Bitmain about the dead board. Bimain had me do all the things I already tried which did not work of course. Now they expect my to pay to ship their defective board back out of my pocket to determine if the board is defective or if there was "improper use".

Bottom line, avoid this company, buy a different ASIC.

I've passed it up the line, it might not affect your case but will try and get the policy changed.

I'm still up in the air on what to do with my dead board.  Shipping to China as the tech who responded to my ticket suggested will cost me $90+ (over $120 if i put it in a box instead of a Pak).

I found this site https://bitmain.zendesk.com/hc/en-us (https://bitmain.zendesk.com/hc/en-us) which if it is real and part of Bitmain (seems like it is as the phone number on the zendesk site matches the US number on the Bitmain site) then the shipping would only be about $12, which would be much easier to swallow.

I am contacting them now and will see where this goes.

They really do have great support.  Let us know how it goes.

But all should go well :)

hi! everyone :)

got a problem one of my S5.

- when i start it the red light blink once then afterwards the yellow light is on. but it's not hashing anymore.
- im using 750w psu all good i tried it on another s5 its working.
- when i do ip scan i can't detect the ip scan of the broken s5 and i cant do a hard reset on it. after pressing
  it for 10 secs nothing happens.

anyone got a similar problem and got a solution please help me

thanks in advance

What is the make and model of the PSU?

i'm using 750w FSP - http://www.fsplifestyle.com/product.php?LID=1&PSN=384

any way to get the ip address on my s5? seems i can't get it with the normal ip scan program i use.
and i can't hard reset the unit

Doesn't sound like something that can be fixed, the controller appears to be bricked. Create a ticket at bitmain.zendesk.com to arrange to return the controller.

ok. :(

havn't tried removing parts from my miner.
is it easy to remove the controller or ill send the whole s5 unit instead?

You will make a ticket here - https://bitmain.zendesk.com .   If Dogie is correct most likely they will have you send in controller and they send out new one (assuming it is under warranty). But shoot them a ticket and they will let you know :)

hi!

thanks for the reply. i send them an email i got a respond they told me to use microSD

You can try with prepared microSD card.
Please take a look at https://bitmain.zendesk.com/hc/en-us/articles/204339655-How-to-create-a-bootable-MicroSD-card-with-factory-setting-
You can download firmware from our zendesk portal here: https://bitmain.zendesk.com/hc/en-us/articles/203461209-Jan-7-Firmware-Image
You will need Windows computer and HDDRawCopy.
After you prepare microSD with image put it in the slot on contol board (while device turned off) and then turn device on.

i try this one hope it will help

anyone tried this one using micro SD card?

I didn't have much luck with bitmain.zendesk.com.  The first tech asked me to re-diagnose the problem and wanted the email chain from my Bitmain China ticket.  After which he said he would get back to me. 

The next day after not getting a response I inquired about the status and got a second tech who wanted me to do all the same stuff despite me telling him that I had the defective part detached, in a box, and ready to ship.  He then said he would get back to me. 

The next day again after getting no response I inquired again and you guessed it the tech wanted me to start from the beginning again.  Luckily during these 3 days Bitmain China responded that they would pay for the shipping back to the China facility.  It should be delivered there tomorrow. Knock on wood I'll have a replacement early next week, end of this week if I'm really lucky.

I warn all future buyers Asik Bitmain. Acquired 3 months ago 2 Asik Antminer S5 (Asik came on board the old version, it was noticeable that Asik have used, but I closed my eyes to it), but as soon as the last 3 months on a single charge Asik began to unravel, a company spokesman said that the guarantee It has already passed. And replace the board as I understand it will not be.

Attention! I warn prospective buyers of these products rely on having beaten the buck is not necessary, and certainly count on future income. Products not only send B / Y, but fail board pretty quickly. What consequence will not bring income. Think again, and think again, it is worth it to buy such Asik! Seller is clearly sends Asik has spent its life. Net sucking money lohah. Do not Think, do not be suckers!

i got my replacement from china for my s5 board.  :)

problem now  is.. it only hash around 670 gh/s my other s5 is around 1100th/s
i flash it with new firmware already. Do i need to adjust something to make it same as my other s5?

Can you post a screenshot of the status page please?

Once he post's I have a feeling it's going to be showing 1 blade only.

Chances are he needs to do some of the standard things to see if he can get other blade back up and running.

I was having the same problem when I got my replacement board. I saw a ton of HW errors and found underclocking would actually increase the hash rate and reduce the errors.  I switched to a different PSU and the problem went away.

Sounds reasonable. The S5 is the first mainstream miner [S3++ the very first] that is susceptible to ~12V problems which could be anywhere from 11.4 to 12.6V. Non string miners take ~12V and don't care due to their voltage regulation, where as new gen string miners have to take ~12V and make do with it.

thanks for the reply guys :D

just found out after flashing latest image... frequency was downclock. so adjusted it and its back to normal now :)

HI
thank you for this useful post.
Maybe my question has been asked already, if so I'm sorry about that, and please point me to the answer.
I would like to know whether is there a way to configure more than 1 miner at the same time, and if so how.
Thank you

Hello,

First of all, thanks for all the info you guys provided in this thread. Very helpful.

What I would like to know is what I might require for the setup of, let's say, 50 Antminer S5 besides the miners themselves and the power supplies.

Multiminer sounds what you need.



If you're keeping them remotely then a cheap windows based laptop to put on the same network with teamviewer. Apart from that, ethernet cables, mains power cables, PDUs potentially, ethernet switches.

That's a lot of cables  ;D

What about the Internet connection? Will it require ultra-high speed? I'm in Italy atm and these guys are infamous for not-so-good ISPs.

No, bandwidth is almost non existent. Lower ping <100ms helps a tiny amount, but mining is still more than possible on even a phone connection.

Thanks a bunch, kind sir.

Pls. find below my customer experience with Bitmain.

https://bitcointalk.org/index.php?topic=1141392.0

Hi, I'm not sure if this is the right thread but I'm having trouble getting Bitmain to respond to my S5 support tickets.

I bought 34 S5's in mid-July and have had trouble with 4 of them.

1) A tantalum capacitor on one of them blew up, and both boards on the unit appear to be non-functioning, not just the one with the bad capacitor.

2) On a different unit, the fan quit. I used the fan from #1 to replace it. No biggie.

3) Ticket $ 3140: One unit purchased at the end of Batch 5, and sold as a new one, has one bad board with only 11 working chips. I told them I tested a different PSU but it didn't help. Bitmain suggested I try re-applying the thermal paste, which I did with no difference. Then they suggested I use at least a 750W PSU instead of a 600W, which I don't understand how they got the idea I am using a 600W PSU when I am using 1 of their 1600W PSUs to power two S5's. (Some poor soul must have cut himself on the heat sink blades as there was blood on the case when it arrived. Eeeew!)

4) Controller on one was no longer responding, so I replaced it with the controller from #1 also. It is working OK.

I wouldn't have done all this except that Bitmain's response to take #3 apart and try and fix it myself kind of shook my confidence that they would do anything at all.

However, I took 4 problems and turned them into just 1 and 1/2  :) I sent them Ticket #3277 to explain the issues.

But as I see it, Bitmain owes me 1 working S5 and 1 working S5 board. (Or I could run it as an S5-  Hm.)

As they seem to be sold out of S5s, I'd take a refund or a 2.7 BTC coupon on the new S7 (estimated)

Anything else I can do?

Thanks!

Proper would be the official S5 thread.  Anymore before you do anything you need to get permission I think they have cracked down.   Did any of the purchases come during the used batch?  If so I could see that being a problem as they might look at order dates and I believe it had 30 day's warranty so it could be over.  Also did you buy direct from Bitmain?

But post in official S5 thread, PM official account, send email.    The ticket should do it, but the other options are there.   But ticket should work assuming you meet warranty requirements.

I received my S5 this week from Bitmain, hashing good for couples of day then stop responding.
Can't get an IP out of my controller. I reset it, boot it via SD card, nothing work.
Ethernet led blinks but didn't show-up any IP.

Ticket open,  waiting Bitmain response on that.

Edit : I find my problem, hub module giving me some trouble...  reset and fixed.  My bad. ..

hello good day.. any one know that how i can do solo mining because i have 45Th/s and i want to found my own block... please guide me..thankyou

Look into pools such as this: http://solo.ckpool.org/  With it everything is already setup you just point miner to an address.

Can I ask how do you have 45 T.  Care to share pictures would love to see it?

With only 45TH it'd take on average 70 days to find a block with no difficulty increases. That means there's a reasonable chance you will never find a block with your equipment - is that really worth the gamble?

Has anyone got the Miner Link to work on their S5's

What's the trick?

on my two units, selecting on, filling in my registered email address and clicking the save & apply only makes it think for a few seconds and then it goes back to the off state

what is odd though, for the miner link server, it lists "www.minerlink.com" ... no specific port or sub page. Is this correct?

I'm using the very latest update with the fan control

Can anyone recommend a pair of quieter fans please?

Been looking at high performance Corsair 120mm will they do the job?

SP120s won't cut it in non cool ambients, S5 is just too open and relies on flailing air everywhere.

LoL ... you make it sound as if the S5 has a "Bounce House" blower attached to it ( I have one of those .... you could probably have 5 S5's lined up front to back with one of those blower feeding the first one. )

Just keep the cat and small dogs away from the intake.... they might get vacuumed up ....

Ha ha I've ordered a single G839 Noctua NF-F12 Industrial PPC 3000RPM PWM 120mm High Performance Fan to try.

Its rated as 4 pin, 3000rpm, 109.8 CFM lets see how that gets on :).

For the record the Noctua fan has been working fine for over a week now. Much quieter than the stock fan :).

At stock (350MHz) it runs at 2200-2400rpm and is probably half the standard fan noise.

Software showing no higher than 60 degrees, more like 54-58.

Please note: I do only have this one running so doubt this fan would perform adequately in a multi miner / hot environment.

What is your ambient?

Today its about 13/14 degrees C or 55/57 F. Outside its 5 degrees C and there is no other heating on. Board temps are 53 C + 56 C and fan is running at 2280 rpm. Its keeping the chill nicely off my 10'x10' office and kitchen which it leads on to because the door is always open :).

Wow, this was perfect. Thanks so much Dogie!

Hi Guys,

My s5 has been sick lately ever since Jan 1st.... online with no hashing.... Freezes quite frequently too...
I had to reboot regularly and changed to lower freq but still sick.
No bad chips. HWE% is very low. Latest FW. Temps 40s
Any ideas how to cure this puppy.... underclock? additional fans?
Perhaps it's the symptom to its old age....
I hate to write this off.... the S5 is still a very good workhorse.

Thanks
TMT

What kind of numbers are you getting? Also, just curious, at what point are you pulling out of mining, since these S5s are getting so outdated? I'm getting about 0.0055 BTC/day right now.

Cheers,
-Flash

Around there or less depending on electricity costs.
I use my s5 for solo mining at ckpool and try my luck - even 1 lucky hit will pay off this puppy.
1TH is not that attractive anymore unless you are happy with 3-4 bucks per week.

Yes I agree as a S5 owner the difficulty is too much. It started at 93+

The S5 was great though and now it seems to feel like my S1 when I replaced it with the S5. renting a S7 it definitely much better hash wise

Are you still using your S5 for anything or does it pretty much sit around now? I'm running mine for a week, then will be repurposing to either solo mining for the random chance it hits big, or to another coin. Really interested in what others are doing, since I'm not in the right spot to buy a new, bigger rig.

Can you give us a screenshot of the status page please?

UPDATE:

I gave the S5 a good cleanup - I got it used in the first place - so I cleaned the front and back fans, wd40 got rid the rust on fan grill, used a computer blower, changed PSU cables, mounted it vertically, like my other miners (S7), changed the network cable and port..... so basically gave it a good rub... and finally it runs and well, hashing at 400mhz for a full day now.

I guess, I didn't give it enough love like its older brother, the S7s.

BTW, Is there a way to add a 4th backup pool in the configuration page?

hi,
 I need to reset the password on the web interface of my s5. I don't know what it is. will a factory reset on the miner ( paperclip to press down and hold 5-10 seconds) do the trick and should I power down the miner first?
updateI got it by saying ( or typing it) out loud.

Do you still run your S5?  Does it still use this fan?  How did it perform?

I just picked up an S5 and will be looking to replace the fan with something a bit quieter.

I ran it with that fan for about 2 months then sold the S5 on.

It worked fine and was much quieter than the original fan at stock clock speed.

It's still working now as far as I'm aware. I haven't heard otherwise anyway, they're a good quality fan.

I have 3 S5's. One S5 , the BBB gave up the ghost.... so I put it in between the two good ones and have the data cables going from one of the dead S5's hashboards going to an extra connector on the I/O board of each of the good S5's. As for fan control on the brainless S5, noise is not an issue so I just have it running full speed by pulling the white and blue wires out of the fan connector. ( by pressing on the silver tab on the side of the connector, you can release the socket pin.)

Although my electric is $0.14111 per KW/h,  I still run the S5's for mining a select few of other altcoins. Those are altcoins that I have seen a consistent performance lately that are poised to become quite profitable after the bitcoin reward halving in June. I'm mining them for investment, not for instant profit.

My S7's are quickly becoming unprofitable with my electric rate. Soon I'm going to have to move the S7's to an office or apartment with free energy that has rent less than what I pay for electricity at home at the moment --- I've done this when I had S2's, let me tell you, landlords don't like it ;-) --- or I'll have to find a datacenter that has low low loooowww fees/electric or be landlord friendly and rent an apartment in South Dakota to house my miners, South Dakota electric rates are CHEAP! although being a 10-12hr drive. I have the equipment to make things completely controllable via the internet (IE hard reset via turning the power off, remote monitoring for climate conditions etc ) so I only have to go out there when catastrophic failure happens ... like one completely dies or a tornado decides to come rumbling through.


By doing so, the S5's become profitable again making a whole whopping $1 a day at current BTC value .... whoohoo ... beer money.

this might be a dumb question....but if i solo mined with a s5 would it still be as noisy as normal mining?...

Yes it will make the same noise whatever mining you do.

You can make it considerably quieter by under clocking and / or changing the fan though ;).

thought so thanks and it has 2 fans atm and the sound is insanely loud...

They can be very loud especially with the stock fan :(.

I had a single G839 Noctua NF-F12 Industrial PPC 3000RPM PWM 120mm high performance fan on some S5s I was running a while back and they were pretty effective at cooling and were much quieter than the stock fan :).

because im running 2 fans instead of one is it safe to say i should be able to drop the fan speed percentage to 50%?

Just monitor your temps along with any fan speed changes to check they're okay.

yeh did that and got down to 40% fan speed and temps at highest of about 52....although at daytime ambient will be higher temp so it might not be suitable.....
what is a good temp to aim for? highest i can safely and run it at without dramas?

Try and keep under 60 if you can, obviously lower the better.

I am running just the 1 stock fan at 60% and mine doesn't get any hotter than 53.5.  I'll probably add a pull fan, too, and then over clock a little and keep the fans turned down as much as possible to keep the dB down as much as possible.

set at 40% and im at about 52 degrees max....(in a room thats about 25degrees)

Can somebody help me with PWM fans? I've bought 2 Thermalright TY 143s for my S5. When I plug one into the 2nd fan header it spins up to 1200RPM and stays there. As far as I can tell the pinouts are standard:

Pin	Use	Wire (new)	Wire (stock)
1	GND	Black	Black
2	+12v	Yellow	Red
3	Sense	Green	White
4	Control	Blue	Blue

Why won't my fan do more than 1200RPM? What I want to do is replace the stock fan with both 143s (push-pull) but they won't do the job at this speed.

Maybe it's an issue with the fan, did you plug it into the other plug?  I have a Delta pull fan on my S5 and it is controlled pwm via the second plug just fine.

One of my blades died and I took it out of the rig. When I power the seperate blade on I only get the 4 green LED lights on the bb and the red one. The blade LED does not turn on. I reseated all the cables, tried 3 different PSU's, tried different connection cables. The lights by the ethernet port don't turn on either. And holding in the reset button is unresponsive.

Anyone know what could be wrong with it. It was hashing 650Gh/s easily at a cool 58 degrees.

If I understood that correctly, you removed a blade and the remaining blade is mining fine. The blade you removed does not power on properly and the LED codes seem to suggest its dead.

If that is correct, then... yeah its dead and there's nothing we can do to help here. Keep mining as you are and dispose of / dismantle / play with the dead blade as you see fit.

Well, see, that's the thing. I thought they were dead too. The boards don't light up (red LED on the blade) but when I have them turned on it heats up. So i'm assuming it still works. Another thing I noticed is that the lights on the Ethernet port don't turn on either. Not sure if the beaglebone board is dead or if now both blades are dead. I have another S5 on it's way so I'll mess with the boards on the "new" S5.

Hello, i have several miners that arent booting up so i tried booting from an SD card but its not working either, i read on this forum that you could use the S4 image and then update the firmware to the actual S5 but nothings happening, any ideas?

Try the Enermax Twister Storm @ 3500 RPM / 154 CFM / 11 mm-H2O works like a charm on my S5s even with a substantial overclocking - will try soon on my S7 ;)

I just bought the S5 and the same exact PSU you linked. I had everything running for about 8 minutes before it just shut off. Now when I hit the power button, the fan on the S5 and the PSU spin for 1 second then do nothing. Yes, I have the paperclip in the correct spot. I don't know if the PSU is bad or my miner died... Is there another way I can troubleshoot it?   -thanks
