Would an S3 control board be able to work with S5 Hash boards?

[Deus667]

Hi guys, and happy new year btw...!

I have an S5 that is not working any more and an S3 that has 1 faulty asic chip already...

I was wondering if there would be a way to use the controlboard of the S3 and in some way make it work with the S5?
Would it be possible to flash the S5 OS on it or would it be able to read a board with more asic's on?

Anyone ever tried?

Kind regards!

No it's not possible.

Would it maybe be possible to hook up 4 hash boards on 1 S5 control board maybe?

(Just trying some out of the box thinking coz it seems so sad to have 1 S5 not working anymore...)

Yes that works well, at least with the SD-S5-20150715-fan_ctrl.tar.gz firmware. Not sure about the other versions?

Cool! that is great news...!

Is there anything else I should be aware of or would there be any tips or advice on how to connect and set them up?

I would have thought to lay 2 S5's on the side with the top pointed towards each other so I can connect the 2 hash boards on the control board of the working one.

I suppose I need to turn on the power of the hash boards before turning on the S5's with the control board?

Would the rest then be plug-n-play?

and one last question...
(I should have opened with that, to make sure)
when I tested my hash boards one by one on my original control board they seemed perfectly normal.
it's only when both were on that specific board that I read errors.
never the unit wanted to hash anymore.
every time I tried to change something I got different readings:
once it was the 1st board failing
then the other
then both working but no hashing
then all in ------
So I ended up assuming it has to be the control unit...
Think I could be wrong?
Would there be other ways to test the hash boards without ridking my good S5 I have left?

Get some of these and you will save yourself a lot of trouble;

(It does work on the sides though, its just a real pain.)

If your system is fine with a single Hash board connected but you are getting variable results with both connected then I would suspect the PSU?

I did try the psu that runs my other S5 and still it gives the same weirdness...

When I hook up 1 hash board at a time it shows up completely fine in the "asic status" tab but it still doesn't hash...
That's why I suspected the control board to be bad because from what I read the device should mine with only 1 hash board connected... right?

OK I had misunderstood, thought you had said

I took this as meaning they were hashing ok?

If they are not hashing and the PSU & control board and control cables are tested ok then likely it's a fault on the Hash board.

Yeah... never mind... the 2nd just crapped out on me... like: right now...
are those S5's poorly built maybe?
or did I get ripped off?

Guess that teaches me for not buying the newest model straight from the manufacturer...


Now... honestly... how are my chances to get a good model and not have to wait for ever if I were to order a new one from bitmain?


(this feels like the crying game... )

I never had any problems with S5's. Miners that were running before i got them continued to mine(to this day actually). Unless you're using some PSU that is raping them, they should continue working.

[Deus667]

Yeah... guess I got unlucky... didn't even have them working for 24h...

So... what are your experiences with Bitmain tech and ordering from them?
Can I trust them? Or is it the same russian roulette game?

If you order from them, the thing should be under warranty. So if there is something wrong, it should be fixable, although you would have to ship them back the defective thing at your expenses.

What is the PSU you used that burned a bunch of S5 cards?

I received them with 2 Corsair CX850M
The 12v rail has 70amp over 840w

I connected all 4 power connectors and followed Dogies' "how to"

My guess is something was wrong with them from the start... maybe they were poorly stored somewhere or so...
I don't see how I could burn 2 complete s5's hashboards by just setting them up to my pool and letting them go at standard frequency using the PSU's that came with them in 48h...?
I kept a close eye on the temp because I just got them, so I know nothing seemed to be reading out of the ordinary...

It's really sad... this gives me a bad after taste of ebay...

They're not particularly bad PSU. Not ones you'd expect to surge volt like mad and burn hardware, so thats a bit odd. And if they came in cold, there could be condensation, so you would need to let them heat up and dry off before you plug them in but i'm not sure they would die like that, after a while. I'm stumped.

If its any consolation, the boards are worth something for salvage.
