--coin [Ethash, ProgPOW] Set coin name.
Helps avoid DAG rebuilds when switching back from a dev fee session.
Example: "eth" for Ethereum, "zil" for Zilliqa.
--extra-dag-epoch Allocate extra DAG at GPU for specified epoch. Can be useful for dual mining
of coins like Zilliqa (ZIL). (eg: --extra-dag-epoch 0)
Can be set for each GPU separately by using comma separated list of values
(set to -1 for the GPUs that should not allocate the extra DAG).
--nonce-start [Ethash, ProgPOW] Starting nonce for the solution search.
--nonce-range-size [Ethash, ProgPOW] Nonce range size for nonce search. The range will be split between all devices.
-d, --devices Comma separated list of CUDA devices to use.
Device IDs start counting from 0.
--pci-indexing Sort devices by PCI bus ID. Device IDs start with 0.
--ab-indexing Afterburner indexing (same as --pci-indexing but starts from 1).
-i, --intensity GPU intensity 8-25 (default: auto).
Controls the GPU workload size, in other words how many nonces the miner is
processing "in one go": N = 2 ^ intensity
--low-load Low load mode (default: 0). 1 - enabled, 0 - disabled.
Reduces the load on the GPUs if possible. Can be set to a comma separated string to enable
the mode for a subset of the GPU list (eg: --low-load 0,0,1,0)
--kernel [Ethash] Choose CUDA kernel (default: 0). Range from 0 to 5.
Set to 0 to enable auto-tuning: the miner will benchmark each kernel and select the fastest.
Can be set to a comma separated list to apply different values to different cards.
(eg: --kernel 2,1,1,3)
The support for this parameter may later be extended to cover other algorithms.
--gpu-init-mode Enables DAG sequential initialization (default: 0).
0 - all GPUs are initialized in parallel
1 - fully sequential initialization, one GPU at a time
2 - two GPUs at a time
etc.
--dag-build-mode [Ethash, ProgPOW, Octopus] Controls how DAG is built (default: 0).
0 - auto (miner will choose the most appropriate mode based on the GPU model)
1 - default (suitable for most graphics cards)
2 - recommended for 30xx cards to prevent invalid shares
Can be set to a comma separated list to apply different values to different cards.
(eg: --dag-build-mode 1,1,2,1)
--keep-gpu-busy Continue mining even in case of pool connection loss.
Useful when a GPU crashes during start/stop cycle that occurs when internet
connection goes down.
-o, --url URL of the mining pool in the following format: <scheme>://<host>:<port>
Supported schemes: stratum+tcp

within "M" minutes.
Format: N:M:A. Valid values:
N: any positive integer,
M: any positive integer,
A: r(system reboot), s(system shutdown), e(miner exit)
Actions "r" and "s" require running the miner with administrative privileges.
Examples:
20:10:s - watchdog will shutdown the system if the miner gets restarted 20 times
within any 10 minute interval
5:7:r - watchdog will reboot the system if the miner gets restarted 5 times
within any 7 minute interval

(eg: --fork-at x16rv2=time:2019-10-01T16:00:00).
To change main pool port you must write it right after algo: <algo_name>:<port_number>
(eg: --fork-at x16rv2:4081=time:2019-10-01T16:00:00).
--script-start Executes user script right after miner start (eg: --script-start path_to_user_script)

------------------ GPU fine tuning (Windows & Linux) ----------------
--pl Sets GPU power limit (Windows - in percent, Linux - in Watts)
Requires running the miner with administrative privileges.
--lock-cclock Specifies desired locked GPU core clock speed in MHz. (default: 0 - disabled).
Requires running the miner with administrative privileges.
Example: --lock-cclock 1000 (applies clock 1000Mhz to all cards that support this functionality)
--lock-cclock 1000,1300,0 (applies clock 1000Mhz to GPU #0, 1300MHz to GPU #1, ignore GPU #2)
--mt Memory tweak mode (default: 0 - disabled). Range from 0 to 6. General recommendation
is to start with 1, and then increase only if the GPU is stable.
The effect is similar to that of ETHlargementPill.
Supported on Pascal GPUs with GDDR5 or GDDR5X memory only.
Requires running the miner with administrative privileges.
Can be set to a comma separated list to apply different values to different cards.
Example: --mt 4 (applies tweak mode #4 to all cards that support this functionality)
--mt 3,3,3,0 (applies tweak mode #3 to all cards except the last one)
------------------ GPU fine tuning (Windows only) ------------------
All options can be set to a comma separated list to apply different values to
different cards. (default value for all options: 0 - not used)
--fan Sets GPU fan speed in percent or target temperature (auto-fan).
Valid formats:
--fan N (where N is the fan speed)
--fan t:N (where N is the target core temperature)
--fan t:N[T1-T2] (same as above, but with the fan speed constrained by [T1%, T2%] range)
--fan tm:N (where N is the target memory temperature)
--fan tm:N[T1-T2] (same as above, but with the fan speed constrained by [T1%, T2%] range)
Example: --fan 45,t:67,tm:95,t:69[45-100],tm:90[50-95]
which translates to
GPU #0: set fan speed to 45%
GPU #1: maintain GPU core temperature at 67C
GPU #2: maintain GPU memory temperature at 90C
GPU #3: maintain GPU core temperature at 69C
with the fan speed limited to [45%, 100%] range
GPU #4: maintain GPU memory temperature at 90C
with the fan speed limited to [50%, 95%] range
Note: fan speeds are limited to [0%, 100%] range in auto-fan mode by default.

Requires running the miner with administrative privileges.
Will be set to 0 on exit and during DAG rebuild.
