Had a partial failure of a D3 Hashboard. Lost 5 of the 60 chips, and had about 10k of HD's on that board.
Followed the Bitmain instructions, sent in a picture of the serial # some screen shots they wanted, located the board, and sent it in.
Took about 10 days, and I got the replacement board today. (Warranty repair.) My only cost was shipping the board.
Had been over on EasyHash when this site was having problems, but really
![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif)
do not like the cost of getting the BTC's.
So will be back up and running here tonight and see if I can make any money. Dropped my clock speed to 487 from 531. This dropped my PCB and Chip temp by 6 and 13 C.
Still clocking at 17.7 GHz.

We shall see if it will pay the electric bill with these low prices.
