Announcing BFGMiner 3.10, the modular ASIC/FPGA 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.
Please consider donating: 1QATWksNFGeUJCWBrN4g6hGM178Lovm7Wh
If you are donating for a specific bugfix/feature request, please post the Issue number and it will be flagged as "funded".
If you find a bug or have a suggestion, please check to see if it's already been reported and, if not, report it.
Help can also be obtained (or provided) by joining the support mailing list or IRC: chat.freenode.net #eligius
READ THE README 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 me 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.
For miners using ModMiner, X6500, or ZTEX devices, you will need to download bitstreams for BFGMiner 3+ to work with your device. Download links and instructions are included in the README.FPGA file.

- Very low overhead free C code for Linux and Windows with very low CPU usage
- Long poll support - will use longpoll from any pool if primary pool does not support it
- epoll support for interrupting FPGA waiting when new work is available without timeout-looping
- Self detection of new blocks with a mini-database for slow/failing longpoll scenarios, maximum work efficiency and minimum rejects
- Heavily threaded code hands out work retrieval and work submission to separate threads to not hinder devices working
- Caching of submissions during transient network outages
- Preemptive fetching of work prior to completion of current work
- Local generation of more valid work (rollntime) whenever possible, as supported on a per-work item basis
- Prevention of stale work submission on new block (submitold also supported)
- Automatically detects failing pools and disables them
- Multi-device support (all or discrete selection)
- Summarised and discrete device data statistics of requests, accepts, rejects, hw errors, efficiency and utility
- Watchdog thread to restart idle threads but not crash machine if they don't respond
- Summary displayed when quitting
- Supports multiple pools with multiple intelligent failover mechanisms
- On the fly menu based management of most settings
- Trickling of extra work to backup pools if primary pool is responding but slow
- On the fly enabling/disable/restarting of devices
- Device temperature monitoring (for devices that support it)
- Reuses persistent connections when possible
- RPC +/- JSON interface for remote control
- Ability to cope with slow routers
- X-Reject-Reason support
- Lots of other stuff I can't remember. See options.
