BzMiner v9.1.0 introduced a 100% LHR unlocker, which was only semi-stable. v9.1.3 has much higher stability and hashrate.
If a card becomes unstable (eg. lhr exception), lower overclocks, and lower --lhr_stability.
--lhr_stability has an impact on both hashrate and stability of the LHR unlock. Higher values will increase hashrate, but may cause GPUs to crash. Lower values are more stable, but may cause LHR to trigger momentarily, lowering hashrate a little. Play with it.
To disable the LHR unlocker, set --lhr_stability to 0. Default is 100.
The LHR unlock can sometimes trigger an "LHR Exception". If this happens, lower the --lhr_stability option. This "exception" will allow the device to continue mining, but at a much slower speed. It requires a hard device reset to recover, which means restarting the pc. BzMiner provides the --lhr_exception option, which if set to true and a card experiences the LHR exception, will reboot the pc.

Solo: Currently only solo mining is possible, and the mining address must be set in the nodes dcrd.conf file
username and password must match what you have in your node's dcrd.conf file eg. rpcuser=username rpcpass=password miningaddr=0000
On windows, the default location of dcrd.conf is: C:\Users\username\AppData\Local\Dcrd
On linux, the default location of dcrd.conf is: /home/username/.dcrd/dcrd.conf
dcrd windows binaries can be found currently at: https://github.com/decred/decred-binaries/releases download and unpack decred-windows-amd64-v1.8.0.zip launch dcrd.exe, the appdata folder will be created and a default dcrd.conf file will be created modify the dcrd.conf file with above information (username, password, mining address) and relaunch dcrd.exe
MUST WAIT FOR NODE TO SYNC! (otherwise bz will just keep attempting to reconnect)
-w 0000 is just to make bz happy right now
bzminer -a decred -w 0000 -p https://127.0.0.1:9109 -r username --pool_password password --nc 1
Kaspa mining currently requires a node running (experimental pool implementation provided in BzMiner)
For solo mining, use node+tcp
bzminer -a kaspa -w 000000 -p node+tcp://127.0.0.1:16110
For pool mining change "node" to "stratum"
bzminer -a kaspa -w 000000 -p stratum+tcp://pool.us.woolypooly.com:3112
Solo and pool both use the GetWork http/https protocol
bzminer -a ixi -w 000000 -p http://ixian.changeling.biz:8081

How to solo mine Ironfish:
- follow guide at https://ironfish.network/docs/onboarding/iron-fish-tutorial to install ironfish
- run the ironfish node using the command
ironfish start - run the ironfish pool using the command
ironfish miners:pools:start - if your node is on a separate pc from bz, replace 127.0.0.1 with the ip address of the pc the node is running on (eg. 192.168.1.2)

Zil is only able to be mined during certain times of the day, so it's usually an algo you want to dual or triple mine with
bzminer -a zil -w 0000 -p zmp://zil.flexpool.io
Zil can be mined with any other algo. Example below shows Erg + Zil
bzminer -a ergo -w 0000 -p stratum-ergo.flypool.org:3333 --a2 zil --w2 1111 --p2 zmp://zil.flexpool.io
Zil can be mined with any other dual combo. Example below shows Erg + Kaspa + Zil
bzminer -a ergo -w 0000 -p stratum-ergo.flypool.org:3333 --a2 kaspa --w2 1111 --p2 stratum+tcp://pool.woolypooly.com:3112 --a3 zil --w3 2222 --p3 zmp://zil.flexpool.io
Bzminer supports changing the overclocks for gpus between algo changes. A common example of this is doing a core algo like kaspa and a memory hard algo like zil, where each algo wants a different oc for best performance. This can be done from the command line or from config.txt.
From the command line, you will set the oc_ options for the first algo (kaspa), and oc_...2 options for the second algo. When the second algo starts, it will apply it's oc to the card. when it ends, it will apply the first algos oc. Example:
bzminer -a kaspa -w 0000 -p stratum+tcp://pool.woolypooly.com:3112 --a2 zil --w2 1111 --p2 zmp://zil.flexpool.io --oc_fan_speed 100 --oc_core_clock_offset 100 --oc_lock_memory_clock 810 -- oc_power_limit 200 --oc_fan_speed2 100 --oc_core_clock_offset2 -100 --oc_lock_memory_clock2 0 --oc_memory_clock_offset 1000 --oc_power_limit2 200 --oc_delay_ms 50
Current BzMiner supports overclocking for Nvidia only, but provides an option called oc_script which allows you to call a script to use a third party software to set the oc, which is useful for AMD cards.
The oc_script option will be called wheneve the oc is set for a particular GPU. If this option is specified, all other oc_ options are ignored.
The script is called with parameters --gpu_index {gpu index} --gpu_id {gpu id} --algo {algorithm oc is being set for}. for example:
ocscript.bat --gpu_index 0 --gpu_id 1:0 --algo zil
This is also useful when you have many rigs with different gpu's. you can create a profile in your mining os's interface for all your rigs, and give each rig its own script to set oc's for
You can change the multi mining type using the multi_mine_type option in the command line. By default its set to 0 for parallel mining, but can be set to 1 for alternate mining or 2 for mine only during DAG generation
BzMiner has a couple "optimized" combinations. These are below: - Ethw + Alph (Nvidia only, experimental) - Ethw + Kaspa (Nvidia only, experimental) - Ethw + Radiant (Nvidia only, experimental) - Etc + Alph (Nvidia only, experimental) - Etc + Kaspa (Nvidia only, experimental) - Etc + Radiant (Nvidia only, experimental) - Ergo + Kaspa (Nvidia only, experimental) - Ergo + Radiant (Nvidia only, experimental)
BzMiner supports a couple console input actions:
Esc- Shuts down BzMinerSpace- Refresh console outputArrow Keys- Adjust intensity, up/down first algo, left/right second algo
The GUI desktop app has been discontinued as of v4.3 in favor of the browser gui, which can be accessed by opening index.html, or by navigating to http://your-rigs-ip:port/ in your favorite browser.
The GUI will display (and allow you to navigate to) other rigs running BzMiner. This is done through a UDP broadcast message which can be disabled on instances of BzMiner by setting "disable_udp" to true in the config file.
BzMiner is a command line interface. Simply update config.txt and launch bzminer.
bzminer has an optional parameter, -c, which can be called to load a different configuration file. eg. bzminer -c custom_config.txt.
bzminer also has optional parameters for setting the pool url, wallet address, algorithm and rig/worker name for all devices

The configuration file is in the json file format, and can be manually updated, or updated through bzminer.exe's remote commands.
There are three main sections:
- pool_configs - This contains a list of your pools. You can add as many pools as you want, even if your not currently mining to them
- global settings/device defaults - this contains global settings and default settings for devices if the devices do not specify those settings
- device_overrides - this contains a list of the devices on your system. By default they will use the device default settings
BzMiner reads and saves to the configuration file. Upon first running BzMiner, the configuration file will be updated with a new property called device_overrides, which contain a list of all the mining devices found on the pc. This is where individual device settings can be set.

GPU's can be disabled either through the command line or through config.txt
The command line argument is --disable and expects a space separated list of gpu unique ids, or indexes
eg.
bzminer --disable 1:0 3:0
or
bzminer --disable 0 3 5
Optionally they can be disabled directly from the config.txt file, under the gpu in the config.txt file, set auto_start to false
Bz has an autofan ability to keep gpu at a target temperature. Set the target fan speed (as percentage) for devices, separated by a space. 0 = auto, -1 = ignore, 100 = max. Optionally use target temperature format, eg. --oc_fan_speed t:N[fMin-fMax] where t is core, tm is mem , N is target temp, fMin is min fan speed percent, fMax is max fan speed percent fMin and fMax are optional eg. --oc_fan_speed t:75[25-75] tm:85[50-100] eg. --oc_fan_speed m:65
config.txt example:
"oc_fan_speed": ["t:75", "t:72"]
where gpu 0 will target the core temp 75c and gpu 1 will target the memory temp 72c
BzMiner will color code certain elements based on whether they are causing the GPU to throttle (slowdown). Current Core and Memory temperatures, as well as Power limit are supported.
Core/Memory - Green if not throttling. Red if GPU is throttling due to high temps. Yellow if GPU is close to throttling due to high temps
Power Limit - Power usage will be white when not causing GPU to throttle. Power usage will turn yellow when GPU is throttling do to power limit being reached.
To employ this strategy:
- Add the two coins to the pool_config section you wish to mine to, or use the command line
- Set either the global "pool" setting, or device override "pool" setting to use both pool_configs. eg. "pool": [0, 1]
- Run bzminer using that config. eg.
bzminer -c config.txt - Or optionally run with the command line similar to this:
bzminer -a ethash -w 000000 -p stratum+tcp://us1.ethermine.org:4444 --a2 kaspa --w2 kaspa:000000 --p2 stratum+tcp://pool.us.woolypooly.com:3112 -ais the first algo,-wis first algo wallet,-pis first algo pool--a2is second algo,--w2is second algo wallet,--p2is second algo pool- Intensity can be set for first algo with
-iand for second algo with--i2 - The first intensity value controls the overal GPU workload for both algorithms when in parallel mining mode (default, multi_mine_type = 1)
- The second intensity value controls the "ratio" between the two algos. A higher second intensity, the more hashrate the second algo gets. It's a multiple of the first algo's hashrate. So a value of 10 would mean the second algo gets the same hashrate as the first algo. A value of 20 would mean the second algo gets double the hashrate as the first algo. When in parallel mining mode (dual mining), the second algo intensity has no maximum value.
v9.2.1 introduced optimized dual mining for specific algorithms. these combinations are supported:
- Ethw + Kaspa (Nvidia only, experimental)
- Etc + Kaspa (Nvidia only, experimental)
- Erg + Kaspa (Nvidia only, experimental)
- Ethw + Radiant (Nvidia only, experimental)
- Etc + Radiant (Nvidia only, experimental)
- Erg + Radiant (Nvidia only, experimental)
- Eth + Alph (Nvidia only, experimental)
- Etc + Alph (Nvidia only, experimental)
Use the max_dual_autotune_drop option to change behavior of dual autotune. by default this is 0.92, which means autotune will attempt to get maximum hashrate for both algos, but keep first algo (etc) at 92% hashrate or higher
BzMiner allows alternate/split mining by using the multi_mine_type option. Default is 0, parallel. By setting it to 1, the algorithms will take turns mining on the gpu. The duration they mine can be specified in the multi_mine_ms option, which takes an array [firstalgoms, secondalgoms]
BzMiner allows you to set an overclock for each algo you are dual mining. Be aware that extreme oc's can much easier cause a GPU to hang (crash) in this scenario, and for that reason the config option oc_delay_ms is used, to give the oc time to kick in before switching to next algo.
Here's a sample dual mine config with oc's per algo:

BzMiner allows you to customize the output displays. This includes the table width, title color, border color, and which columns in each table to show.
There are two tables that are logged by default, the devices table, and the pool tables. On each display update, the devices table is logged, which contain information about all the devices on the system. This table is not in the context of a pool, so does not support some of the column options the pool tables support, including hashrate.
The Pool table is logged for each pool that devices are mining to. If there are two devices on the system, and each device is mining to a different pool (or different algorithm), then there will be two pool tables in the output, one for each pool. This table supports all the columns in the device table, as well as columns specific to the pool context.
default device column configuration: "#,name:nw,cfg,free,total,core,mem,fan,pwr,temp"
default pool column configuration: "#,uptime,a/r/i,avg,eff,pool mh,miner mh,status:nw"

The pool table has an additional row at the bottom which is the summary of all devices mining to that pool. The status column for the pool includes the epoch number, difficulty, and average latency to pool.
To update the column in config.txt (hiveos):
"pool_columns": "#,a/r/i,cfg,tbs,tsls,eff,pool_hr,miner_hr,status"
- Colors are integers and correspond to normal terminal color codes. Default BzMiner logging color is 7.
- Columns are a comma separated string. do not include spaces unless the column name includes spaces (eg. "pool mh"). Columns can have options (currently just one), which is specified by adding a colon (:) after the column name, and specifying the option, eg
name:nw. Two supported options;nw, which prevents that particular column from wrapping to the next line if the column cannot get wide enough to support the entire value on one line, andnc, which disables coloring of the column values
Urls should be in the form of {protocol}+{tcp/ssl}:{url}:{port} (username and password are optional)
eg. stratum+tcp://us1.ethermine.org:4444
If username and password are required, eg. {protocol}+{tcp/ssl}:<{username}:{password}@>{url}:{port}, they can be set per device in the config file, or through the command line. If device pool_username is blank, it will use the rig name from the config file. if pool_password is blank, it will use the default pool_password for the rig in the config file. Leave both pool_password blank if no password is required for the pool. Do not put the username and password in the url (If there are enough requests for this, this can be added in a future release)
BzMiner supports 4 network protocols
- Node - use
nodeorsolo - Stratum - use
stratum - Eth Proxy - use
ethproxy - Ethereum Stratum v1.0.0 - use
ethstratum - Ethereum Stratum v2.0.0 - use
ethstratum2 - Alephium Binary Stratum - use
alphstratum - HTTP or HTTPS GetWork - use
httporhttps
BzMiner will attempt to auto select a protocol the pool supports if the provided protocol does not succeed in establishing a connection with the pool.
HTTP API can be enabled by launching bzminer with the --http_enabled flag, or by setting "http_enabled": true in the config file.
For more details, enable the http api, and go to http://{http_address}:{http port}/help. If you are on the same computer, you can use localhost or 127.0.0.1 as the http_address.
A simple viewer can be found at /index when the HTTP API is enabled. index.html is provided for your convenience.
By default, the wathdog service is running. The watdog service watches for:
- Hung GPU (GPU not responding after a period of time)
- Unresponsive network activity
- Unresponsive main loop
- BzMiner crashing
If a hung GPU is detected, the watchdog service will optionally call a script specified in the config file, then optionally reboot the rig if specified in the config file.
The last log (and output) from BzMiner before the optional script is called is in the format of:
<Error> Hung GPU detected! (bus_id:device_id)
Which could be read from the called script if needed.
The watchdog also restarts BzMiner if BzMiner crashes for whatever reason. This shouldn't normally happen, but the occasional bug can cause BzMiner to crash, and with the wathdog service, it'll start back up again. The watchdog service also restarts BzMiner in instances of unresponsive network activity and an unresponsive main loop.
