Have you found the problem?How did you fix it?

It's not working control board, we had the same issue with a miner in skycoinlab.

I think it is not about firmware, but bad control board.

Try with several version of firmwares starting from newest to oldest who knows which version suits the best in your case.

It does not hash a any frequency higher then 100.

I have bought a Enermax Platimax 1000W PSU.I have tried it with the S5 miner.No difference.It only hashes (between 3 and 50) at 100 frequency.

There is temperature value at only one board.All chips seems to work (ooooooo).

I have also checked the cables.

Should I try to upgrade the firmware (I have resetted) ?

Any suggestions?

I worry for you check this review out.

you are somewhere in between test 3 and test 4


the psu flatout crashes on test 4.   which is 60 amps at 12 volts or 720 dc and of course  you should be using

 1150 x .52 = 598 dc at stock settings    while 600 out of 720 sounds good.  if you run 24/7/365  you need to derate by 20%  so 720 x .8 =  576 dc

and stock setting is going to use 598 dc.

So you are running them beyond safe derating.  and we do not know  what safe is since 720 failed  so 720 x .8 = 576 is not really safe.

and you have 100 of them.   I really suggest  dropping your freq setting under stock 350 it simply is not safe.

But I am not an electrical guy. just a miner.

if I had to run those psu's with s-5's I would start at freq 275 and maybe raise a bit to 287.5 or 300

Well you did what you know it will work by the numbers but not all S5 are the same, you have various revisions of hashing boards and control boards and they do not behave the same. When I test problematic device I use Enermax Platimax 1000W just to be sure that PSU is not the culprit. I had situations where hashing pcb was damaged in some way probably because of too weak PSU and when I tried on Platimax everything worked well.

I will receieve new PSUs today.I will report the results.

I am running one S5 with CX750 Corsair.If it is a borderline PSU we are in trouble we have more than a hundred with this configuration.

this is good advice


using a cx750  is using a borderline psu.



@ op or @ gabley12
also freq 100 is not too stable try freq 250  let it run  for 20 minutes  see if you get 750 gh or a little better then that

Try with stronger single rail PSU and then report results.

4 seperate cables on CX750.

I cannot remember for sure on this.  Does the CX750 have 4 SEPERATE pcie power cords?  Not the connectors but actual cords going to pcie.

The frequency is 100 because I wanted to try if it is a PSU related problem.I have several PSUs, same brand.When I tried the other one I get some hash at 100 frequency.Can both PSUs may be problematic?When I increased the freq to 300 or 350 it does not hash.

My PSU is Corsair CX750.

Pls find below the link of status page.

What model is your current PSU?  Can you take a screenshot of your status page?

I have got a similar problem.The only difference is I have got temperature '35'.

What do you suugest?I have ordered a PSU tester and will check PSU.Anyone who has an idea is wellcome.

A little late he solved the problem - https://bitcointalksearch.org/topic/m.11479301

I would definitely check the power supply. I have the same issue with one of mine, only to find out after getting a tester that one of my 12V legs was bad on the PSU.

It's not a bad idea at all.  I'm so use to paperclips I just keep doing it (besides the nice evga that include a jumper).  But those antminer switches are very nice.  And they don't cost to much.

Something  else if you can find a offbrand PSU tester for cheap you can plug motherboard end into it and use it to keep PSU on.

I ended up purchasing a couple of the "Antminer Power Supply Jumper" gadgets. Search around, and you get a couple for about $3-4 each, less if you buy multiple. They aren't fancy, but they resolve the issues, and make it trivial to "power cycle" your miner when needed. Yes, they are more expensive than electrical tape and paper clip. They even include a little LED to tell you that the power supply is actually powered up.

Glad to hear it works!   Yea it can be loud and hot.  That is normal though.

I suggest using electrical tape to keep paperclip in place.  With doing this you don't have to worry about it slipping out of pins.

I think I had my Paper Clip in the wrong position.  Played with where it went and fan came on all the sudden.  Yup, just confirmed it too by looking at miner just now and of course fan is being noisy now lol.  Sounds like my darn R9 290x when I am full speed on X11 or something.

I am starting to think it is a PSU Issue.  Mainly because of what I have read about the stock fan being very very loud upon starting the machine and I didn't hear a peeep out of it.  Plus I plugged in my noctua fan and it didn't even do anything after a power cycle, or I have a bad miner.

Have you tried the following:

1) https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB

2) https://bitmain.zendesk.com/hc/en-us/articles/203559969-My-S5-hashes-at-about-600GH-S

Between the two they fix a lot of problems.  If this does not work you might try turning down frequency to test PSU.  But if none of this works you might have to wait on the other psu and see if it fixes the problem.

Tested both boards independently and neither of them will hash, I mean they do great at rejecting everything but won't hash whatsoever.  Zero's across the board except for the discarded column.

I suppose I will wind up finding out Monday if this is a PSU Issue or not.

This is a screenshot of what it is doing.

Might check this thread here - https://bitcointalksearch.org/topic/antminers-s5-miner-status-screen-is-blank-help-1073465

It has a lot of the suggestions that you should try.

So I just got an Antminer S5 today and well it isn't doing anything, well it sort of is, I mean it's discarding everything but other than that not doing much of anything.  I have tried Multipool.us, Westhash, Coinking.io BTCGuild and none of them show it doing anything let alone the miner itself is showing 0 for gh/s.  Now, I know it will be asked so before that, I am using a 650 Watt XFX XTR PSU 80+ Gold, yes I know the PSU is on the low end for power but I wanted to get this up and running before I get my 850 Watt Corsair AX850 Gold PSU on Monday.  Anyway any help or insight would be great. 

If I knew how I would attack my pdf that I took of the screen showing what it is doing.

Oh yea forgot to mention I have put frequency all the way down to 200 and no change in hash, and fan1 is running at 120, Asic Status is all zero's.  I also reflashed the miner with the software from bitmain and didn't change anything.  Also one of the fins on the bottom is kinda of broken, as in it isn't attached to the machine and bent oddly, opened the box that way.

Here is some of my Kernel Log if it will help.
