ANTMINER S4 Discussion and Support Thread

[Prelude]

Going to be getting an S4 soon and was wondering how you guys have dealt with the noise? I know you can underclock it but that kind of defeats the object of it. Not got to worry too much about ambient temps as I'm in the uk and rarely gets above 25c in summer.

I currently have two s3's under my desk in my room and can quite easily sleep with those on all the time so just wondering what the s4 is like in comparison.

Thanks.

--bitmain-homemode

That will slow the fans down. Never had any issues with running them that way, and the temps arent an issue.

where do I input this command to get the fans to slow down?

Thanks.

SSH or Putty. etc/init.d/cgminer.conf if I remember correctly. I probably don't, but the information is somewhere in this thread.

[gt_addict]

have you got some kind of walk through as I don't really have the kind of skills most of you guys have on here with computers.

There are details somewhere in the thread explaining it.

True! This is my PSU.

Got it with the small button.

The only question was: does the system then shut down ? Or is it a cold "switch off" anyway ?

Not a problem at all.  And yes it does hold the little button for a few seconds and entire machine will shut off on S4.

Hold it a few seconds when it's off... and it does the opposite and turns the S4 back on .

Thx!)

Ok i thought this s4 was dead. Then i get all the boards up and running and hashing. As soon as i set my pools and click apply, the s4 goes into a bootloop and the only thing that saves it is a reflash of the sd. Then I turn it on Ethernet unplugged it boots up but not with Ethernet connected, it does the bootloop or restart loop if Ethernet is connected upon start up. If i plug in the Ethernet after ths s4 boots up but only after a fresh sd flash it will stay on and let me flash firmware from the s4 system page. But no matter what firmware I use once i set my pools it goes into and infinite bootloop and Ethernet unplugged trick doesn't work anymore. Could this be a control board issue?
PS
Punching kicking and throwing thing across room doesnt stop bootloop.

Try change first the lan cable and port on switch . i had problems with dust at the rj45 connector on the backbone and i sprayed with contact cleaner, now all is ok

The hardware forum is more for sales then support thread.  Can you show some pics of S4 cooled with water blocks? I'm curious to see what it looks like.

Also you might re-word it above as I highly doubt the S4's are truly new.... maybe new to you.  But for these S4's to have not been used and sit somewhere since being made such a long period is hard to believe.

Waterblocks? That's pretty overkill unless someone wanted a quiet warehouse with overclocked s4s. He could have saved the s4s for some later time, but yeah.. Thats pretty unbelievable. I want to see a picture as well, because it just sounds so cool!

They are listed on eBay

I can't find the auction but someone posted it in another thread.  They had a  VERY custom data center with larget amount of water cooling on a lot of gear.  If I find post later I will post.  

But they are interesting looking.   It is someone no doubt seeing profits decreasing on older gen gear.

is anyone still actually making a profit with these things? i see they still sell on ebay for what i paid a year ago.
 i shut mine down last week after 1 year  of mining as electrical cost ($.10kwh) was more than bitcoin generated.

If you had free electricity then yes you could still make a profit.    I personally shut down my S4's long ago, and sold and bought newer miners.  With "normal" electricity I just could not keep mining them.

I would sell it off personally and buy coins.   I have owned many miners and wanted to keep them all....  but in the end I have sold all old generations and it's been a decent help to my ROI in some cases.

sounds like a plan. i saved the box. time to fire up the ebay sell account...

And this is something that is not talked about much but you really should always save your boxes and original packing material.  I always keep mine and if looks like other boxes write on it what miner it's for.   You will save money on good packing later, and customers are always happier when original box (normally).

But your on the right track heading to ebay with it.  Much better then unplugging and sitting it as decoration in my opinion.

Someone gave me 3 free S4. Should I put them to use or just sell them?
