So I have a die that isn't working. Running at ~260 Mh/s max since receiving it.
I read this on the KNC titan support forum:
1 Test the board individually with different data/power cables. Please also plug the data cable in a different port on the controller board. If this board does not have a die issue when ran individually, it is most likely due to a faulty cable connection, or lack of power from the PSU. If you cannot get the die to switch back on, contact support for more assistance.
I tried all of the recommended steps before emailing support. Not realizing they wanted a screenshot of BFGMiner, I sent them a screenshot of the Advanced screen. A day later Liam responded back that he would need a screenshot of BFGMiner. OK, sent them that.
A day later he responds (paraphrasing) "Oh, I see you're mining at <...> They have problems with the titan. You should switch to one of these pools <...>
Then he closes the ticket.
Riiight, it's the pool causing a die not to work...WTF
