Thanks Philip, I value a lot the time you spent trying to help. I learned alot. It saddens me that one of my S5s lost one board, I will consider sending it to sidehack after holidays.

Id also like to thank everyone else who tried to help. Have a merry christmas and a happy new year.

Sorry, beside messing with cables in case something is loose, its hard to say if there is anything else to try to fix it. The next thing to see, if i missed it, would be to swap the controller to see if the problem follow the blade or the controller. Just to double check its really the blade thats gone bad.

And i also did not see anyone reply for the EVGA G2 1300w. The answer is definitively. You'll lose 1%~ AC/DC conversion efficiency over optimum load however. I'd run two of them at 393hz on one.

I have another S5 and its working perfectly since day one, running OCed at 400M. Needless to say... proof is quite clear that we are looking at a dead hashing board. Sad

I asked the EVGA question since the first reasoning seemed to be a dead PSU (I have a couple of spare EVGA 1300w). I thought that if my Corsair died I maybe could've run both my S5s on one EVGA 1300w.

Well, yes you could. Most of my S5 do 393 for 1.29TH/s. One of them do 1.32TH/s at 400, but the others don't get the right voltage it seem, so i leave them at 393.

Could be either cable, psu, or board.

If you dont have a second PSU you may use a voltmetre and check voltage.
Switch cables

If anything work, then the problem could happen from the S5, try to reduce frequency again.

Maybe switch power cable and wall switch too.

In other words, some tinkering has to be done to find out the source of the problem.

The cables were tested, I also tested the PSU as I have an identical one, it all points at a dead hashing board. Disgracefully.

''disgracefully'' Yess I understand.

Then except lowering frequencies you could power on only the good boards and then adjust at a raisonable frequency. You wont have a perfect S5, but still, the other board is working.
Sry for your loss.

Do I need to remove the board in order to power it off?

If I check the Bitmain S5 manual ; https://bitmaintech.com/files/download/AntMiner-S5%20user%20guide.pdf

Page 4

You may see that you can power up a S5 with 2 differents psu. Instead of using the 4 pcie connectors, only use 2 on the same ''line''.

When youll get your working board, then youll be able to adjust your frequency on it. You may be able to get some unused power from your psu to be able to do some secure overclocking. It is what I would try if I were you.

Felt that 20 mins were enough for this test, the results are shown on the image: http://imgur.com/r1ZSpve

well it looks like it is dead.

any other tests would need a different s-5 and swapping the dead board to a known working

s-5.

sidehack was taking dead s-5 boards and  going to make smaller pods from them.  you could send it to him and i think you get a pod back.

I am not sure of anyone doing repairs on the boards since they are now an older generation of gear.

Get back with that test as soon as you can

Done the test, shows different result but no good..

After 30 min with cables fully swapped: http://imgur.com/8HOWMD4

Im now proceeding to do the next test which is returning the cables to original hash board but swapping with empty slots on controller board.

Ok, will report back in 30 after I fully swap cables from hash boards and controller.

Seems to be doing the same thing my bad s5 board did. It seemed normal after a power cycle but after a little while it would drop most/all the chips on a board, it never had any hashing speed. Did you try swapping to the other jack on the controller board?

EDIT: thats a first for me to see

I could try that. Is this the correct procedure?

- Turn off.
- Unplug the two cables that go from each board to the controller.
- Attach the two cables to the extra two slots on the controller board.
- Turn on.

?
before you do that just swap them the cables fully and do the 30 min test.

I want to see if the problem follows the cable.

My guess is the problem will not follow the cable. You will then be sure that both cables to the controller work.

 Then do your idea keep the cables on the same hash boards and plug them into the other two controller jacks
If the problem occurs it is the one board  and it is broken.

I would say mine with one board and consider sending the dead board to forum member sidehack.

I think he is making them into pods.

Well, this is weird!

30 min test with 300 freq: http://imgur.com/S4aB1rA
Do notice that HWs are over 1%..

Sad to say that I did everything that everyone suggested and nothing worked:

- Power cycled: Problem Persisted
- Switched PSU with another Corsair CX 750: Problem Persisted
- Lowered Frequency to 300: Problem Persisted

Its giving me 6-10% HWs...

Heres an image showing the S5 hashing at 350 Freq with another PSU: http://imgur.com/VOKDPll


problem could be the cable to the controller.

also are you using all 4 pcies  jacks on the s-5
with the psu?

also a less then 2 minute test at freq 350 does not show me much.

how about 30 minutes at freq 300

Okay, will report back with the screenshot after 30 min at 300 freq. And yes, Im using the 4 pcie jacks on the S5 with the PSU.
