ANTMINER S4 Discussion and Support Thread

[mrpark]

My account says I have 51 coupons for S4, can it be right? 17 for S3+, and 17 for C1. Anyone who can tell me how to extract them individually, maybe I can send you one.

Just wanna know when is the shipping for batch 2 S4, I have no idea when will be the exact shipping date?

Ordered S4 2014-11-12 , Shipped 2014-11-14. I can pick it up tomorrow.

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. 

if your giving them away, send some here:   jackzach640@Yahoo.com

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.

Keep working with MrGreenHat until he runs out, then hit me up! 

I'll make the same offer; I have over 100 of these $400 off coupons, and I'd love for someone to put them to good use.  I just bought 2 more S4s today, and I don't think I'll be buying any more for a little while. 

PM me with your Bitmain user ID, and I'll provide you with a BTC address to send donations to.

Heh, Ill offer the same deal myself, or 10/0.02BTC. I imagine there are thousands of these coupons distributed in total.

You guys are lucky.

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

I'm 54-60 in sunny England.

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.

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

Hard reset for that. I had one and a soft reset just makes it worse

Talking about that... my chain 1 goes offline after about 1-2 days running, sometimes in a matter of few hours. GUI will be reporting as if nothing wrong. You'll only notice when your hash rate at pool end drops. You can also look into the casing via the fans, you should be able to see 4 red leds if all chains are running. Was thinking of taking the S4 to a host but with me constantly having to look to see if there is 4 red leds, not going to be possible. Plus having to hard reset when you get "Hugs & Kisses".. makes it even more impossible to have the S4 hosted.

Could it be a firmware issue or hardware?

Hi everyone,
i have got a strange problem with my Antminer S4 batch2, i listed founded problems:
1-my S4's has different connections with FPGA controller, one of them is top left hash board connected to J7, other s4 same board is connected to J6. this is very strange or poor assembly.
2-this J7 connector is going to the first hash board i think, but other  hash boards red led is off except this J7 connected board led blink. 5 minutes waiting then this board getting hot and another five minutes all boards leds are on. then all of them is hot but THERE IS NO ETHERNET CONNECTION.  
3-i worried power comp. and i changed 0720 to 0700 then i measured all hash boards voltages on 1500uF/2,5V capacitor.. wouuwww THERE WAS A PROBLEM! because we can never change 1 hash board's (j7 connected) voltage. this is allways 0750V. than i read confidential pdf of CSD95372B and TPS53641 this is i2c controlled buck converter and this is controlled by pic12f1822 on every hash board. So this 0,750 Volt i measured is over voltage protection limit.
i am an electronic engineer by the way.

I ASK TO BITMAINTECH,
WHY OUR HASH BOARDS HASHING SOMETHING STANDALONE (or why warming up) AND WHY 3 HASH BOARDS VOLTAGE CONFIGURABLE BUT 1 IS NOT ?

thanks, any ideas ?

B2 shipping from near stock AFAIK.

Hard to tell unfortunately, I'll check to see if its a known bug.

Thank you. Much appreciated.

And for compensation of the lost mining time...

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

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

How much BTC did you receive from them?

Has anyone else been compensated? I'm still waiting on mine.

[Prelude]

Just got my 3rd S4 in, waiting on 2 more.  



All mining on P2Pool.

S4 1 has an "x" chip, thus it's lower speed. S4 3 is hotter because it's still in my house, going to bring it out to the garage later.

40C so hot *mumbles*

[mrpark]

Do you mind If I ask why, it takes at least 6 months of 24x7 mining just to break even.

BitmainTech don't love me as much as some of you. I only got 1 C1, 1 S3+ and 3 S4 coupons. I am wanting to give the C1 and S4 coupons to someone who can use them. All I ask for is a donation to help me buy my S3+ as I am 0.3 BTC short for the pair. Please PM me if you would like one or all of them and the amount you are willing to donate.

I also want to make a note on here about BitmainTech giving me the run around for a power lead. I asked them about the 16A lead and told them I was on a 240V power system. After a couple of emails with BitmainTech they were still amendment that I needed a 16A lead and told me to find one online, which I couldn't because the C13 connector is only rated for 10A@250V. After a couple of emails with BitmainTech I gave up speaking with them and spoke with my electrician to see if he could get me the lead BitmainTech was talking about. He told me that the BitmainTech customer support staff don't know what they are talking about and that the 10A lead would fine to use. I then asked BitmainTech to confirm this with someone there that knows about power usage. Surprisingly this time they came back with a different response and told me that the info the electrician gave me was correct. I asked them to update their info on their website for other people on 220-240V so it is not confusing but they have not done so.

So the rule is -
120V needs 16A
240V only needs the standard 10A

I also have some hashing issue with my S4 but I will post that another time. It's too late and I need some sleep.

Hmm wonder if that is what happened to me. After running flawlessly for 22 days on Sunday one of my S4's dropped to only 1.2-1.3ths, checked the gui, all chains reporting good and still have CK's fix applied so wasn't a power glitch causing a full reboot. Did a soft reboot, reapplied CK's tweak and came right back up to full speed. I do still suspect power so have an always on-line ups coming for it just to be sure. So far it is only the S2 and S4 Beaglebone based miners that have been needing the ups's, S1 & 3's seem to handle power dips just fine

If it happens again I'll check the activity lights.
