You see it on checkout...

Sorry for sounding dumb however I am not seeing it on checkout. Is it after confirming? I believe it should allow me to add the coupon before confirming and I see only confirm option.


No option of adding coupon in cart and at checkout it shows "No Coupon" under coupon column and everything is grayed out so no way to add the coupon.

How sad. I would have bought one with the coupon.

what SD card do you have in there?

class 10 solves some issues

try removing the 3rd pool if you have one

I just got the stock SD that comes with the miner, but I could try with another that I got around
I just got 2 pools right now

How can I be sure if it's the power supply or the SD card ?

make a bootable sd card-see page 86
change, see if anything happens (don't forget to change pool info)  Smiley
if nothing good happens, and I doubt it will with sd card change, then change power supply if you have a spare 1200w or 1300W.
simpler solutions:
1. make sure that outtake fans are not close to the wall (they have to be at least 50cm away)
2. room temperature is at or below 35oC

the only way is try changing them one at a time - SD first as its easier.

Well, so I am having issues with my B2 unit  Cry
From time to it usually powered off itself and I have to open, take the click out and put back in and everything works ok for some time. But today it happens like every 20 minutes or so.
All the asics works ok and I have no further problem, so I guess my power supply is dead yes ?
Does Bitmain provides a new one ?

Hi edgar,

In our previous communication, we agreed to RMA your DOA board and guided you how to ship back the the issue hash board to us. Both shipping label and UPS account are available for global customers. We even traced the the track # in the shipping label we offer you, which is showed 'valid' on UPS page, please call local UPS and try it again.
We will try our best to support you to fix your problems.

By the way, S2 will not fire if it is just missing capacitor, but it is true that the hash rate will be lower than 1Th/s if one board is not wotking normally.



Many Thanks... UPS arrived at 1820 and collected the board.

I look forward to receiving a 'new' board in the coming week/s and some capacitors that i might 'fix' the rig myself as it is 'just missing capacitors', fingers crossed it will all go smoothly.

Some thermal paste would be appreciated though seemingly not particularly necessary according to whomever applies it in the first place. would you advise users to check and perhaps reapply correctly thermal compound to each and every antminer board/heatsink or was i merely unfortunate to have received 'one' such as in the image i sent to you?

if providing sufficient thermal compound is too much please let me know at your earliest convenience that i may order some out of my own pocket before the 'new' blade eventually arrives.

i shall assume you can spare a dozen assorted capacitors?

Your flippant 'by the way' clarification wrt the 'just missing capacitors' safety concern is not unappreciated, however other customers put my fears to rest hours previously for which i remain sincerely grateful for.

Having issues with my S2 B3.     Since I got the unit, it has never run stable @ 1Thz.   

It may run for a while at 1 Thz, but then I will notice the speed decrease anywhere from 700-900 ghz and will have boards xxx or ---- on the miner status page

What pool are you using?  I have a similar problem when using it on p2pool, except it's always well below 1th/s, and seems to decrease as time goes on.  BTCG rejects 30% of the work of one of my S2s.  Eleigius (through a stratum proxy) works best so far.

Currently using Bitminter.  Was on Ghash for a while but speeds were even lower there.  I have had better luck with Bitminter than btcguild and ghash.

Pulled a board out this morning and hasn't flaked out on me yet.  Running around 850 right now

Thank You Dropt!

how hard was that??

I have tried calling the telephone number provided  by Bitmain - the 1st timeit was answered but only heavy breathing/silence.

subsequent calls have been left to time out or purposefully ended without answering.

if anyone else is struggling to contact them, +86 151 124 53849 is the contact number that will more than likely not be answered.


BITMAIN - are you too busy to reply or merely ignoring my emails, PMs & telephone calls??

why would you provide UPS shipping information that UPS themselves cannot identify or accept??



The way this is going, it will be another 7-10 days to get this simple, single blade replaced.... what kind of service is this?

Quote from: edgar on Today at 00:27:55

can you tell me what the capacitors actually do?

do you think there is any risk of fire??

Hi edgar,
Relax, if it is wokring normally now, should not bring any bad results, the worst case is that the miner runs with less than 1 Th/s.


apparently the risk of less than 1Th/s is worse than the risk of fire/explosion...

and now it seems i may be back on the ignore list - UPS cant accept the package with the label Bitmain provided and he is yet to provide updated info despite being requested over an hour ago

Educated guess: the caps are for reducing ripple voltage/noise in the switching dc/dc regulators.  The chips may flake out but it's not going to catch fire and/or blow up if they're not there.
