This happened last night after 6 months of hashing no problem. It hasn't had the smoothest Internet in the world and Im aware of the No Internet fan problem on this devices.. Any advice or comment?

Thank you

Look at the board see if you can see anything missing or damaged/burnt.  If you see anything iffy take a good quality picture and post it in this thread, if you can or are willing to try a repair we can point you in a direction to hopefully get your board running again.

Sure, give me a moment. I will upload pictures as soon as possible.

I dont see anything burnt but here are the pictures of the two boards:

I also have a friend who went out on a trip for 15 days and when he came back he had one board full of xxxxxxxxxx. He tells me he just rebooted and it went back up.

Well the first thing one should do is power cycle it. Then swap the connectors. Then swap PSU. Someone with a genuinely new broken S5 board happen regularly, so that could be the case. But i see people with not actually broken hardware more often.

Also, what is your PSU?

Excuse my ignorance, but what do you mean by power cycling it? Im running it on a Corsair CX750

You unplug the PSU for 10-20 seconds waiting for the power already in the circuit to dissipate, then you turn it back on. Its the first thing you do, equivalent to restarting your router when your network is acting up. (Though power cycling the router might be a more effective way to trouble shoot networking issues as well)

My guess is the psu has given up the ghost.  it is borderline good for the s-5.

since it still runs some what.  change the freq to 300 see if it works better

[dannygroove]

Thank you, ill try all of that as soon as I get home. On another note, do you think 1 EVGA 1300 gold PSU  can stand the load of two S5?

[dannygroove]

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...

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.

[dannygroove]

Well, this is weird!

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

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.

[dannygroove]

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

[dannygroove]

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.

[philipma1957]

Get back with that test as soon as you can
