New price for AntMiner S2 1 TH/s Miner Batch 4: 2264 USD each one, shipping cost included.

Pack your miners better please. Almost had a ruined miner.



Happily it is mining away at 1 Th/s after an hour. Please please please fix how you ship the S2, because cards shouldn't be sloshing about in transit.

Looks like they could use some foam strips under the hold down brackets to improve contact between the edge of the board and the bracket.
Maybe some self adhesive foam weather stripping on the bottom of the hold down brackets ?

My batch 2 S2 has been hashing at around 1 TH/s since I got it a month ago.  

However, in the last two days the hash rate has fallen to an average of 900 GH/s.

You would think a blade had failed, but I don't think so because sometimes it still hits 1 TH/s.  The chart on the pool shows it hovering mostly around 900 GH/s.

Has anyone else had this issue?

Nope. Mine dips into the 900s and occasionally goes as high as 1280 if the front panel can be believed but averages on the pool ~ 1TH
There does seem to be a temperature related throttling mechanism in place. Just guessing - perhaps it is a heat sink contact issue ?

Were you waiting for the Bitmain signal to post the image?

Bitmain how many sales are you prepared to lose until you decide to start shipping the S2 with all card removed and individually bubble wrapped or encased in foam? Your target market for S2 are all highly capable to insert blades in slots.

No way I'm sending you 2 thousand dollars to have a jumbled box of damaged junk land at my doorstep.

Batch 4 S2s still unacceptable despite your weak attempts to correct.

I love my dozens S1s. I'll give you credit for those. Well built and well shipped.

The above is the reason why I'm hesitant to pull the trigger on a S2 either direct or through Juan's groupbuy...

[philipma1957]

yes I have been held back for this very reason.


 that and really low prices on the s-1's  I just spent the end of my s-1 coupon's today… 


 I have 6 or 8 s-2 coupon's that i may never use. 

 basically bitmaintech makes very good gear..  but if you get  a bad piece of gear it is always a set back.  so on 200-300 usd s-1's  I can live with this.

  but on a 2k piece of gear no.

[tzortz]

That is why you cannot find easily  S1 coupons for donation anymore.

S2 coupons are plenty out there.

Just to update: I SSH'd into the S2 to have a look. Couldn't see anything wrong. It had been up for a month, so I tried rebooting it. Problem solved, it is hashing at 1TH/s again.

Strange that it should slow down after a month of uptime, but I guess rebooting it once a month is pretty minimal hassle. See if it happens again in a month's time...

even my s-1's just stop once or twice a month.

That is not normal.

My batch 3 S2 is plagued with problems.

1. Impossible to reboot/shutdown(Hot or cold) without having do SD recovery. (SD recovery never works first time around)
2. 1 blade intermittently gets XXX00XX ---XX--00 in ASIC status
3. 1 blade permanently gets XXX00XX ASIC Status
4. 1 blade after 2 days stops hashing and temperature shows its about 20 degrees cooler.

Asked for repeated RMA but support keeps on ignoring requests or offers troubleshooting solutions that are no longer relevant.  

Pretty pitiful really, I don't how this unit could have passed their Quality Control process.

[psjw4450]

I received a unit today that all the cards were all over the place. 3 of the connectors were bent and a 4th was ripped off completely.  Also 2 of the fan pins were mangled.  I emailed bitmain and asked for a refund as the unit has no hope of being repaired.
