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.
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.
