BFGMiner 5.5.0: CPU/GPU/FPGA/ASIC mining software, GBT+Stratum, RPC, Linux/Win64

Announcing BFGMiner 5.5, the modular cryptocurrency miner written in C. BFGMiner features dynamic clocking, monitoring, and remote interface capabilities. “St. Barbara’s Faithfully Glorified Mining Initiative Naturally Exceeding Rivals”, or just basically a freaking good miner. This code is provided entirely free of charge by the programmer, so donations would be greatly appreciated.

Help can also be obtained (or provided) by joining the support mailing list or IRC: chat.freenode.net #eligius

Do NOT send me a private message directly, as I will ignore your message. I only provide support in public, so that others may benefit from the answer too. (An exception is if you want to pay me for direct support. In that case, please say so in your message.)

READ THE README FILES INCLUDED IN THE ARCHIVE BEFORE ASKING QUESTIONS.

Also, please note that this thread is for discussion of BFGMiner, its features and bugs – if you feel the need to troll or talk off-topic, start another forum thread (and PM me with it if you want my attention).

If you want to help develop BFGMiner, the best way to get in touch with us is on IRC.
We also have a development mailing list, mainly used to pre-announce upcoming releases for third-party packagers.

If you would like to be notified of new versions, please join the announcement mailing list.
