Work keeps going to my backup pool even though my primary pool hasn't failed? BFGMiner checks for conditions where the primary pool is lagging and will pass some work to the backup servers under those conditions.
The reason for doing this is to try its absolute best to keep the devices working on something useful and not risk idle periods. You can disable this behaviour with the option --failover-only. Is this a virus? As BFGMiner is being packaged with other trojan scripts, some antivirus software is falsely accusing bfgminer.
If you installed BFGMiner yourself from a reputable source then you do not have a virus on your computer. Complain to your antivirus software company.
They seem to be flagging even source code from BFGMiner as malicious now, even though text source files can't do anything by themselves. Can you modify the display to include more of one thing in the output and less of another, or can you change the quiet mode or can you add yet another output mode?
Everyone will always have their own view of what is important to monitor. The defaults are very sane and I have very little interest in changing this any further. Efficiency simply means how many shares you return for the amount of bandwidth used.
It does not correlate with efficient use of your hardware, and is a measure of a combination of hardware speed, block luck, pool design and many other factors. Most user defined settings lead to worse performance. What happened to CPU mining? Being increasingly irrelevant for most users, and a maintenance issue, it is no longer under active development and will not be supported unless someone steps up to help maintain it.
For builds which do support CPU mining, it is still disabled by default, and must be enabled using the -S cpu: Will there ever be a GUI version? No, however the RPC interface makes it possible for someone else to write one if they choose. I'm having an issue. What debugging information should I provide? It is highly recommended not to mine on a Mac unless it is with an external USB device.
My network gets slower and slower and then dies for a minute? A; Try the --net-delay option if you are on a getwork or GBT server. How do I tune for P2Pool? P2Pool has very rapid expiration of work and new blocks, it is suggested you decrease intensity by 1 from your optimal value, and decrease GPU threads to 1 with -g 1.
It is also recommended to use --failover-only since the work is effectively like a different block chain. If mining with a Mini Rig, it is worth adding the --bfl-range option. No, the APIs are slightly different between the different software and they will not work. Why does it fail when php is installed properly but I only get errors about Sockets not working in the logs?
What is a PGA? Since the acronym needs to be only 3 characters, the "Field-" part has been skipped. What is an ASIC? They are Application Specify Integrated Circuit devices and provide the highest performance per unit power due to being dedicated to only one purpose.
OpenWrt drivers install with opkg: I ran cgminer, and now BFGMiner doesn't work! Before you can use BFGMiner, you will need to restore the original driver. Removing the device from Device Manager and re-plugging it will usually trigger driver re-installation to the default drivers.
Why does BFGMiner show difficulty 0 when mining scrypt? BFGMiner consistently uses pdiff measurement for difficulty everywhere, rather than other measurements that may exist. For scrypt, pdiff 1 is very difficult, and higher get exponentially harder.
What is stratum and how do I use it? Stratum is a protocol designed to reduce resources for mining pools at the cost of keeping the miner in the dark and blindly transferring his mining authority to the pool.
It is a return to the problems of the old centralized "getwork" protocol, but capable of scaling to hardware of any speed like the standard GBT protocol. Stratum uses direct TCP connections to the pool and thus it will NOT currently work through a http proxy but will work via a socks proxy if you need to use one. Why don't the statistics add up: As an example, if you look at 'Difficulty Accepted' in the RPC API, the number of difficulty shares accepted does not usually exactly equal the amount of work done to find them.
If you are mining at 8 difficulty, then you would expect on average to find one 8 difficulty share, per 8 single difficulty shares found. However, the number is actually random and converges over time as it is an average, not an exact value, thus you may find more or less than the expected average.

Single pool with a standard http proxy:. Single pool with a socks5 proxy:. The list of proxy types are:.
Proxy support requires cURL version 7. If you specify the --socks-proxy option to BFGMiner, it will only be applied to.
After saving configuration from the menu, you do not need to give BFGMiner any. Any configuration file may also contain a single. Writing the configuration will save all settings from all files to the output.
Everything you probably want, condensed:. Video card GPU mining free:. CPU mining optimized assembly algorithms:. BFGMiner specific configuration options:. No installation is necessary. You may run BFGMiner from the build directory. Native WIN32 build instructions: If you build BFGMiner from source, it is recommended that you run it from the. Run "bfgminer --help" to see options:. Options for both config file and command line:. This overrides --api-network and you must specify By default any command that does not just display data returns access denied.

The 8 byte hex value are the 2nd set of 32 bits from the share submitted to the. The 2 diff values are the actual difficulty target that share reached. Also many issues and FAQs are covered in the forum threads. The block display shows:. This shows a short stretch of the current block, the next block's height and. The BFGMiner status line shows:. ST is STaged work items ready to use.
F is network Failure occasions server down or slow to provide work. NB is New Blocks detected on the network. AS is Active Submissions shares in the process of submitting. E is Efficiency defined as number of shares accepted multiplied by their.
BS is the all time Best Share difficulty you've found. The totals line shows the following:. Each column is as follows:. The number of devices and processors currently mining. Hottest temperature reported by any processor. An all time average hash rate. An all time average hash rate based on actual nonces found, adjusted for pool. The number of Accepted shares. The number of Rejected shares and stale shares discarded never submitted ,. The number of HardWare errors, and percentage invalid of nonces returned.
Columns are the same as in the totals line. A number of different strategies for dealing with multipool setups are. Each has their advantages and disadvantages so multiple strategies. This means that if you input a number of. If any of the earlier pools recover, it will. This strategy only moves from one pool to the next when the current one falls. This strategy moves at user-defined intervals from one active pool to the next,. While a pool is disabled.
If all pools are set to zero quota or all pools with quota are dead, it will. The failover-only flag has special meaning in combination with load-balance. This strategy monitors the amount of difficulty 1 shares solved for each pool. To use this mode, you need to specify the URL of your bitcoind node. If you are solo mining with more than one instance of BFGMiner or any. GBT-enabled pool, even when not solo mining such as failover.
Note that solo mining does not use shares, so BFGMiner's adjusted. Example solo mining usage:. The load-balance multipool strategy works off a quota based scheduler. For example, if all the quota values add up to ,. Quotas can be changed on the fly with RPC,. Setting a quota to zero will effectively.
While a pool is dead, it loses its quota and no attempt is made to catch up. To specify quotas on the command line, pools should be specified with a. To use the above. Not all graphics cards are compatible; various software is required e. GPU , the official documentation for bfgminer on github:. To start scrypt mining with bfgminer and GPUs, use the --scrypt and -S opencl: You can use an older version of CGMiner i. By posting your answer, you agree to the privacy policy and terms of service.
