Hi,
Recently i bought 25 antminer s5's. it took 2 month to arrived because of my location
And now i have problem with 3 of them! I don't wanna return them to bitmain now, because of late in shipment.
One of them wont start mining and i can't access to setup page neither. how can i flash s5 with micro sd card? i found image file here:https://bitmain.zendesk.com/hc/en-us/articles/203461209-Jan-7-Firmware-Image
and wrote in to sd card with HDD Raw Copy Imaging tool. but i don't know how to flash it!

Boot it up with the SD card in and it should flash the image automatically.

I did that and leave it for an hour but not working.

Does it boot up at all if you leave the SD card in there?

No, nothing.
Can i use firmware image from s4 or something? maybe this image file corrupted.

You could try just to see if it boots.

Thanks.
I tried to boot another healthy s5 with this image file (s5 image file) and it works.
so i don't know what's wrong!

Have you tried using the reset button?

yes,not working.

Most likely your controller board is not coming back.  I have a feeling you will need to replace it.   It is not as good as the S4, C1 on recovering from SD always.

But put in a ticket - https://bitmain.zendesk.com/hc/en-us  .  But I have a feeling it will be needed to be replaced.

Yes. you are right. BBB board was the problem. i replaced and now working fine. thanks for the link.

I have 2 more asics with problems!
One of them doesn't show the temperature:

The main thing is the reading on your other board is still telling the fan it needs to do something. So,I think you're good to go. 

(note: One of my S3s had the same problem. However both fans run fine.  It's now 13 mths old and still hashes like it was new...and that's after running thru the winter at 500+ GHS. I just wasn't comfortable selling it off when I sold my other S3s.)

I had the same thing on one unit that did not show temp on one blade.  Bitmain did not care as long as it hashed right.

And I can see their point.   If you have one reading temp it can shutdown if it runs to hot.  So just keep running I would say.

yes. this in not a big deal. i have bigger problem with 2 others!
thanks both of you.

Above are two photos of my Antminer S5 with the plastic taken off.  Now its the only
S5 I have that has this design.  It is almost exactly the same as the S5+ with the chips
having their own individual heatsinks.  I have 3 other AntMiner S5's and they are all the same
like all of the pictures taken of the miners.

Can anyone explain to me why these chips/heatsinks are different?

Did I score the S5+ hashing boards before they were released in a product by mistake

Any knowledge would be great.

Thanks

PS, couldnt figure out how to post a picture straight in the forum so I uploaded them to dropbox.

Any help would be great.

They actually did some with heatsinks.  I'm not sure what batch but they decided it helped with heat, which it does.

I believe they then stopped using them.  I would guess it was based on cost of heatsinks, or time to put them on from workers.  So you don't have a S5+ design but you do have a nice S5 as most do not have the seat sinks.

Not sure what batch mine came out of, but it has the heatsinks as well.
Purchased around 4 1/2 months ago I guess, whatever that makes it.

Some of the V1.91 Hash boards had heatsinks fitted. Could have been a trial for the S5+ / S7? However they are not the S5+ Hash Board. My S5 that has the heatsinks runs a couple of Degrees cooler than one without them. Still a mystery why they omitted 2 of the heatinks in the same position on all boards?

is that wb from the s5 kit or from c1? or the wb are identical in size?

They are identical. (From C1)

[mavericklm]

so c1 wb and s5 wb are identical?

another question: does the s7 blade fit in the c1 case? or that case from syscooling. or is the blade too tall?

thank you!

[Tupsu]

The length of S7 is 301 mm

The length of S5+ is only 275 mm

The lenght of S5+ blade is 180 mm , height 127 mm at lower edge

The length and height of S7 blade are not known.

does the s7 blade fit in the c1 case? I think it does not fit .

[SunnyIgor]

I realy hope syscooling are anyone else will design a s7 watercoold block and or kit.
I was realy hoping the make the old c1 block fit. or order some from syscooling.
I an not looking for a full time vacuum cleaner running 24/7

Can a single pcie 18awg be used to power a single dashboard?

[VirosaGITS]

Can a single pcie 18awg be used to power a single dashboard?

Yes, if the connectors arent crap and the pins properly connect to each other, basically plug it in and touch the connectors a bit later, if they're burning hot then they're no good. If its cold or lukewarm after sustained load there should be no problem. You should be able to put both plugs on one board and it should split the load on the connectors just fine.

[kano]

Well, the S5 is running 300+W per board so it would not be at all surprising finding that getting hot using a single one per side rather than 2 separate per side.
100+W (8.3+A) per wire.

As stated above it depends on the connectors and the wiring.

If it's not much more expensive I'd suggest you get 2 per side just in case, rather than finding later that 1 isn't enough and having to wait to get more cables. Those wires shouldn't be overly expensive ...

I've found that expensive PSUs now tend to use 18G
My first 2 1250W Gold OCZs are all 16G, but my way more expensive 1200W Plainum Seasonics are only 18G (ribon)

[VirosaGITS]

Really? That's pretty disappointing. Only some perif cables are 18awg on the EVGAs i have. Rest is all 16AWG. Goes without saying they remain cold to the touch.

[mavericklm]

i powered 1 s5 from only 2 * 6pins, 16awg, 1 * 6pins/board

cable was warm!

18awg will not resist more than 24h, maybe not even 6hours!

2 independent 18awg i guess will work ok

Hi,

  With the summer hotness I was tired of continuously adjusting my S5 frequency, so I decided myself to dive into shell coding and wrote a small script to do it automatically.

  I'm pretty happy with what I got: every 20 minutes the script checks the temp sensors, increase or decrease the frequency and restarts cgminer. Thus I keep the temp between 58 and 62 °C at all time.

  If you're interested you can download the script on github: https://github.com/kmitz/Regul
  Installation notes are on my blog: https://jomcflyatwork.wordpress.com/

  You can ask me questions in this thread or PM me for help.

  Cheers!

NB: If you worry about my script stealing all your coins, just check the script, it's only 40 lines and very straightforward:
1)read temp
2)write new frequency in /config/cgminer.conf
3)restart cgminer

You may want to disable variable fan control if you haven't already, if it gets cool enough your 3 variables will keep flip flopping.

I have 4 watercooled S5's so 4 blades and 2 controller boards.
the fan speed is constant via watercooling system
I have no fan connceted to any of the s5's
but I can't get the script to work.
1 time it changed freq back to 200 another time it does noting.

I would love some help becouse sometime at night i am seeing temps below 40 on all s5'5

I'm  not one to ask that kind of stuff took me all most a year to figure out how, which service is supported on this site .


I'm to hard headed to ask that kind of stuff

Really nice idea, have downloaded and will give it a go. Have you considered / do you think it's possible to do a version that looks at HW error % and then adjusts up and down?

Thanks
