ANTMINER S4 Discussion and Support Thread

More S1 upgrade kits please!!

you could feasibly use the C1 as a pair of upgrade kits, but its not ideal. Not sure why bitmain isnt selling upgrade kits for ~0.3BTC/kit

How many people would be interested in another S1 upgrade kit batch?

[Tupsu]

I get buy 3 s-4's with a coupon for 2762   if I down clock to 1800gh they burn 1100 watts so 5400 = 3300 watts  this is .611 watts a gh

I'd like to see it. My first S4 worked for a long time with EVGA SUPERNOVA G2 1300W at frequency 181.25M and only 1630GH/s with 1180W
You can never from S4  .611 watts a gh

The second   S4 is  even more power hungry , at frequency 181.25M   1240W and 1800 GH/s
The second S4  PSU is  without a PCI-E cables.

[mavericklm]

do they have special cables and connectors

[DieJohnny]

Do I think they are great investments no I don't.
But they may make money.

I agree with "may" only because probability is not zero.

Those were a lot of fun. I'd be interested as well.

HELP

Just received my Antminer S4 and having a difficult time setting it up.  When turning the machine on it whirls at full speed/noise, but never settles down.  The LCD screen is bright but never displays any text.  Anyone know what the issue is?

This occurs whether directly plugged into my computer, or plugged into a Netgear N300 wifi to Ethernet adapter.  I unscrewed the lid, and all of the cables appear to be plugged in properly.

Popped the SD Card out, and then pushed it back in.  Miner worked!  Stable after adding CK's cgminer mod.  Running 1.82GH at (hopefully) 1060W as suggested on BtcGuild.  Thanks for the help on this thread!

Congrats.  The shipping gods have not been kind to S4s, although all three of mine worked out of the box.  One had a bit of scratched paint.

Mind posting the Freq. and Voltage your using and/or a link to the article you read?

Okay I may grab one or two  of these.  I am interested in under clocked results.   

so is anyone running freq 187.5  with 0.685 volts?       if so what do you  get for hash rate watts/ power numbers and fan speeds?


better yet has anyone done freq 175 with 0.670 volts?  if so what do you get for hashrate watts used and fan speed?

TIA

Ask and yea shall receive (at least sometimes!):  http://puu.sh/d3BqI/ad9aaf7d23.png - 187.5 at 0.685V.

Exactly, coupon expires tomorrow, then free shipping on Dec 2. Marketing at it's best.

wait i want to make sure i understand this clearly?

So they are running coupon and after that expires they are moving into free shipping?

Are the Psu's still going up in flames?

1) Free shipping is a Black Friday deal only, to the best of my knowledge.
Shipping fees are likely to return.
Even though they should definitely not.
Very bad business move cutting that service, as I have no doubts that it has cost them considerable business.
*free shipping is ONLY available for the Black Friday Bundle of sixteen S4 units.

2) Coupons have been extended. Again.
December 15th now I believe.
Still being sold. Still being given away. And now Bitmain offers to give them to anybody for free, regardless of past purchases.
Maybe it is about time Bitmain gives up on coupons.
Talk about an exercise in futility, and a perfect way to alienate and piss off customers.
ADVERTISE THE AFTER COUPON PRICE, AND BE DONE WITH IT.

3) PSU's are not going up in flames 33%+ of the time anymore. It is rare when it happens, and Bitmain is well practiced at replacing PSU quickly now.
I wouldn't let that hold you back anymore.

The idea was probably to take business away from ebay resellers. Right now price is artificially low at bitmain (before you get to shipping), which makes it more competitive with ebay second hand prices (shipping tends to be much lower or free on ebay)

Yes, what is the point of coupons when they are basically permanent? Again, this is probably a move to "decimate" primary resellers that suppose to give discounts to the advertised price, not to the "after coupon" price

I would be interested in about 150pcs of S1 upgrade kits, but only at price I couldnt resist.

How did you guys connect a different power supply to your S4? I think I had a power surge and one of my S4s wont turn on anymore and I want to see if it works with a 1600 watt EVGA PSU. Do I just connect the PCIE cables to the hash boards and then turn on the PSU? I assume the LED screen will no longer turn on as well since it is connected to the factory PSU.

Thank you for any advice on the matter! 

[MyRig]

If you open the case and see PCI-E power connectors being connected to the PCBs inside, then you can connect your EVGA 1600 PSU's PCI-E connectors t each connection point and it should work.

1 PCI-E connection to the Control PCB (Behind the LCD but the connector is facing up)
4 PCI-E connections to the hashing PCB (should be front side 2 on the top and 2 at the bottom)

If you have the newer batch, then the power spec is the same but it uses almost like a terminal screw type connection to each hashing PCB.  One is ground and the other is positive (red)

Has anyone tried the 100 or 125 MHz clock settings provided by Bitmain?  I'm just looking for feedback if everything is working properly, and if the power from the wall is as advertised?  Is there any risk from underclocking?

I'm also curious about the 200Mhz with the lower voltage setting.  If the lower voltage gets the same GH/s while using less electricity, then why not make it the default?  Thoughts?  Any response from Bitmain?

...

Yes.
0650
125M
700W
1160GH/s

There is still too expensive and too big from underclocking.
I prefer underclocked SP20

Anyone experience boards going ------------- halfway during hashing?

I have a miner that would hash fine for a few hours and then show 1.5 TH.

Temps are low. Upon restarting cgminer, it would show one set of hashboards going --------

After multiple reboots I'll get all 0000000 again and hash at full speed but at times, it will go to 1.5 TH again.

I ahve two miners acting like this.

Also the reboot function via the GUI doesn't seem to work and 'hangs' my antminer requiring a cold reboot.
