ANTMINER S4 Discussion and Support Thread

[Namdher]

Got a batch 2 S4 delivered today, and it killed my batch 1 S4 (no, not really but read on..)

So my batch 2 unit wouldn't work out of the box. The display was showing the IP as 127.0.0.1. After a bit of messing around, I figured the SD card was to blame and that a reflash was in order. Since bitmain doesn't offer a full image to download (why don't you, bitmain?), I had to power down my batch 1 S4, pull it's SD card, create an image from it, and flash that image to the new S4's card. Once that was done, the new batch 2 S4 worked as it should. I'm not sure why it didn't work in the first place, since bitmain had obviously tested it judging by the accumulated (very little) dust in the miner.

Now, for my B1 S4... About 30 seconds after the fans calmed down from their initial spin-up, I was treated to a smoke show like to other. A thick stream of Magic Smoke plumed out of the B1 S4's PSU for a good 10 seconds, before going out with an extremely LOUD pop. That loud pop was a short bad enough to trip the 30A 240V breaker that miner was connected to.

To add insult to injury, the event seems to have killed the on-board NIC on a PC that was connected to the same circuit, so that is also out of commission for now.

Alas, my dreams of hashing at 4TH/s went up in a plume of Magic Smoke. Hopefully bitmain will get a new PSU out to me soon, but I'm doubtful. I contacted them about replacing my PSU the day the offered replacements, but I haven't gotten an email back yet. Has anyone received their new PSU yet?

Fortunately I had another S4 to get an image from, if anyone runs into the same issue let me know and I'll upload the image.

HELPPPPPPP MEEEEEEEEEE PLEASE, i have the same problem. I need to know if i can solve this problem.

Gotta love natural Canadian cooling.  

And it isn't even winter yet. If you're wondering, temps are showing 0 because S4's temp sensors don't register below 20c.

So, how cold is it outside where you are?

To anyone else that gets this, you can usually clear it by simply pressing and holding the reset button [on the LCD].

That didn't work in my case, I attempted that twice. Absolutely had to reflash the SD card.

Fixed

Hi, I need to know how to reflash with SD card. Please explain if I would appreciate the help

You'll need to take the SD card out of the S4 and flash it using a full image on a PC. Do you have a laptop with an SD slot or something to write to the card?

0c right now. (32f)

Contact support and ask for a PSU RMA.

And for compensation of the lost mining time...

Speaking of which, has anyone actually received compensation in the form of BTC from bitmain?

[MrGreenHat]

BITMAIN Promotion plan for S3+, S4 and C1

$50 coupon for S3+, $400 coupon for S4 and $50 coupon for C1 are issued to customers who ever bought miners from BITMAIN or our official distributors

Once again, THANK YOU, BITMAIN!!! Very much appreciated!!!!

I did, last week!  For one s4.  It was a nice surprise.

Hi there,

I have a defect fan on my S4. Do you know where on the web I'd find a compatible one, same specs?

In the meantime, my S4 won't start mining because it detects a 0-RPM fan. I tried giving it a manual spin and the S4 started hashing. Do you know how I can tell the S4 to mine even if there's a missing fan, without giving it a spin?

I sent an e-mail to Bitmain but thought it would be faster to get one if I order on the web with priority post or something like that. I'm in Canada.

Thanks!

I got the fan specs from bitmain sometime back as I wanted to look for quieter fans. These are the specs. http://prntscr.com/56s4gz

Thanks a lot for the information!  I'm waiting for an answer from Bitmain and looking at compatible fans in the meantime.

Lol, same thing here, I'm also in Canada and got the s4 out of the house!  The heat was not much of a problem compared to the noise, but hey it's now keeping my lawnmower and all-season tires warm, ready for Spring.

You guys are lucky.

I'm in Singapore and my chips are running between 58-63C depending of the time of the day....

Well when I keep my S4's, S2's and S1's in the garage, even if it's around 0C (32F) outside, it's 40C in the garage and 64C in the miners!  I really have to make a hole in the wall... some kind of dryer output...

I have to keep my garage door open even in winter (there's snow outside as of today) -- the neighbours look at me with interrogation points in the eyes. I look at them with Bitcoin's B in the eyes.

Your HW Error is rather high.. and do you realise you have have a X on one of the chips?

[Seketsuna]

well the month of Dec is coming, temperature will drop so our heating problems will be solved




->I've got a $400 bitcmaintech.com coupon for s4 antminer, im selling it for $125. So you have a $275 discount

No one will buy them.  Bitmain  gave me only 180 S4 coupon. Can you imagine how much the rest of them were?

[MrGreenHat]

I only got 71 $400 off coupons left for the S4! I'll give them away for free just so Seketsuna doesn't make $125 from a single coupon.  


EDIT: OK so my PM inbox has been flooded with requests for free S4 coupons, and everyone who has requested one up until this point either has or will receive one. BITMAIN sent out TONS of coupons to everyone who has ever purchased a product from there. At this point, it's becoming a little time consuming to send out these coupons for free, so if you would like a coupon, I would like to request atleast a .005 BTC donation (currently less than $2 USD, a lot less than the $125 that the other guy was asking )  to my BTC address for my time. Keep this in mind if you PM me from this point forward.
