Hello everyone,
When we were doing the first mass production, we found that not all of the S3’s DC/DC module could be stable enough to support the 478GH/s speed. After long time testing, all of the S3 run stably at 441GH/s, which however is 7.7% less than the 478GH/s we have announced.
So we decide the final specification of ANTMINER S3 here:
Hash Rate: 441 GH/s or more
Power Consumption: about 340 Watt at the wall when running at 441GH/s
Power Efficiency: 0.77 J/GH on wall
Power Supply: 12V DC
Size: 331 mm x 137 mm x 160 mm
Fans: Two 14038 fans mounted on both front and back ends.
Operating Temperature: 0 °C to 35 °C
Complied with: FCC / CE
Network Connection: Ethernet
Many of the customers may be lucky to find that their S3 can be overclocked to 478GH/s.
We apologize for this incident. We offer two options for customers:
1) 10.0% worth of coupon for the B1~B3 customers. This is the default option. (10% based on what you have paid for the B1~B3)
2) 7.7% worth of refund. We will release a function on our official website for application of this option. If you have bought from our resellers, please contact them and provide your Bitcoin address.
Shipping schedule updated:
Batch 1: The shipping will be finished in 14th and 17th.
Batch 2: It will be shipping out between 18th and 19th.
Batch 3: It will be shipping out between 19th and 22nd.

Dear Mr Bitmain
Thank you for being honest and upfront with us and generous with your compensation.
I have many S1's and a few S2's humming away in the background as I write this, all of
these units have performed very well and I have been extremely happy with them.
Regarding the S3 compensation, we in Australia have a law that items under AUD$1000
comes into the country without paying customs fees and taxes, once we go over AUD$1000
then fees and taxes kick in and we have to pay around $220 extra in fees and taxes.
This may apply to other countries as well, I am not sure
The price of 2 X S3 comes in at just on that AUD $1000 limit, when I ordered batch 1, I worked out
the price at AUD$990, but this fluctuates with currency and BTC price movements.
Are you going to reduce the purchase price for customs declarations because of this compensation?
Because I would prefer the coupons but if the declared value is over $1000 then I would prefer
the 7.7% price decrease to keep the total dollar amount under the $1000 limit, could you please
advise how much you are now going to declare the value of these S3's now
thanks again for your great products
Cheers
PS. My batch #1 order is still 'unshipped'
) might get different DCDCs and therefore better performance.
