Re: Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip

You have bought B1~B3 of S3. We will issue you a 10% value coupon. However, you have the option to give up the coupon and apply a 7.7% refund.

So if i apply for the coupon or refund will my antminer order still be valid?

any reason why antminer is doing this? because of delay?

S3 specs were reduced from 478 GH/s down to 441 GH/s, so they are refunding/discounting to fix it

That information is not mentioned on the official website

But it is posted by the official Bitmain user on multiple threads in this forum.

If you log into your Bitmain account (assuming that you placed an order for the S3), you'll see that you are offered either a 10% coupon or 7.7% refund. There have been multiple posts by BITMAIN stating that this is due to their findings while testing the production run S3's.

Cheers
