GETTING STARTED WITH USB ASICS
Unlike other software, cgminer uses direct USB communication instead of the
ancient serial USB communication to be much faster, more reliable and use a
lot less CPU. For this reason, setting up for mining with cgminer on these
devices requires different drivers.
WINDOWS:
On windows, the direct USB support requires the installation of a WinUSB
driver (NOT the ftdi_sio driver), and attach it to the chosen USB device.
When configuring your device, plug it in and wait for windows to attempt to
install a driver on its own. It may think it has succeeded or failed but wait
for it to finish regardless. This is NOT the driver you want installed. At this
point you need to associate your device with the WinUSB driver. The easiest
way to do this is to use the zadig utility which you must right click on and
run as administrator. Then once you plug in your device you can choose the
"list all devices" from the "option" menu and you should be able to see the
device as something like: "BitFORCE SHA256 SC". Choose the install or replace
driver option and select WinUSB. You can either google for zadig or download
it from the cgminer directory in the DOWNLOADS link above.
When you first switch a device over to WinUSB with zadig and it shows that
correctly on the left of the zadig window, but it still gives permission
errors, you may need to unplug the USB miner and then plug it back in. Some
users may need to reboot at this point.
LINUX:
On linux, the direct USB support requires no drivers at all. However due to
permissions issues, you may not be able to mine directly on the devices as a
regular user without giving the user access to the device or by mining as
root (administrator). In order to give your regular user access, you can make
him a member of the plugdev group with the following commands:
sudo usermod -G plugdev -a `whoami`
If your distribution does not have the plugdev group you can create it with:
sudo groupadd plugdev
In order for the BFL devices to instantly be owned by the plugdev group and
accessible by anyone from the plugdev group you can copy the file
"01-cgminer.rules" from the cgminer archive into the /etc/udev/rules.d
directory with the following command:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
After this you can either manually restart udev and re-login, or more easily
just reboot.
OSX:
On OSX, like Linux, no drivers need to be installed. However some devices
like the bitfury USB sticks automatically load a driver thinking they're a
modem and the driver needs to be unloaded for cgminer to work:
sudo kextunload -b com.apple.driver.AppleUSBCDC
sudo kextunload -b com.apple.driver.AppleUSBCDCACMData
There may be a limit to the number of USB devices that you are allowed to start.
The following set of commands, followed by a reboot will increase that:
sudo su
touch /etc/sysctl.conf
echo kern.sysv.semume=100 >> /etc/sysctl.conf
chown root:wheel /etc/sysctl.conf
chmod 0644 /etc/sysctl.conf
Some devices need superuser access to mine on them so cgminer may need to
be started with sudo
i.e.:
sudo cgminer <insert commands here>

--bitmain-temp Set bitmain target temperature
The Antminer S1 device comes with its own operating system and a preinstalled
version of cgminer as part of the flash firmware. No configuration should be
necessary.
ANTMINER U1/2/3 DEVICES
--anu-freq <arg> Set AntminerU1 frequency in MHz, range 150-500 (default: 200)
--au3-freq <arg> Set AntminerU3 frequency in MHz, range 100-250 (default: 225.0)
--au3-volt <arg> Set AntminerU3 voltage in mv, range 725-850, 0 to not set (default: 750)
By default, Antminer U1 devices run at a clockspeed of 200. This command allows
you to specify a chosen frequency to attempt to run all ANU devices at. Cgminer
will try to find the nearest frequency the device supports and will report if
the frequency is not exactly as requested. Note that cgminer reports hashrate
ONLY FROM VALID HASHES so if you increase the frequency but your hashrate does
not increase or it decreases and hardware errors start showing up, you have
overclocked it too much. In the worst case scenario it will fail to start at too
high a speed. Most will run happily up to 250.
ASICMINER BlockErupter Tube/Prisma DEVICES
--bet-clk <arg> Set clockspeed of ASICMINER Tube/Prisma to (arg+1)*10MHz (default: 23)
Default clockspeed for Tube/Prisma is 240MHz. This command allows to set clockspeed
of on board BE200 chips in range from 200MHz to 320MHz. For Tube devices, you can
try overclocking to 270MHz or even higher, but NOT recommended for Prisma devices.
If you notice hash rate drops or board fails to start, restart cgminer with lower
clockspeed.
AVALON AND BITBURNER DEVICES
Currently all known Avalon devices come with their own operating system and
a preinstalled version of cgminer as part of the flash firmware, based on the
most current cgminer version so no configuration should be necessary. It is
possible to plug a USB cable from a PC into the Avalon device and mine using
cgminer as per any other device. It will autodetect and hotplug using default
options. You can customise the avalon behaviour by using the avalon-options
command, and adjust its fan control-temperature relationship with avalon-temp.
By default the avalon will also cut off when its temperature reaches 60
degrees.
All current BitBurner devices (BitBurner X, BitBurner XX and BitBurner Fury)
emulate Avalon devices, whether or not they use Avalon chips.
Avalon commands:
--avalon-auto Adjust avalon overclock frequency dynamically for best hashrate
--avalon-cutoff <arg> Set avalon overheat cut off temperature (default: 60)
--avalon-fan <arg> Set fanspeed percentage for avalon, single value or range (default: 20-100)
--avalon-freq <arg> Set frequency range for avalon-auto, single value or range
--avalon-options <arg> Set avalon options baud:miners:asic:timeout:freq:tech
--avalon-temp <arg> Set avalon target temperature (default: 50)
--bitburner-fury-options <arg> Override avalon-options for BitBurner Fury boards baud:miners:asic:timeout:freq
--bitburner-fury-voltage <arg> Set BitBurner Fury core voltage, in millivolts
--bitburner-voltage <arg> Set BitBurner (Avalon) core voltage, in millivolts
Avalon auto will enable dynamic overclocking gradually increasing and
decreasing the frequency till the highest hashrate that keeps hardware errors
under 2% is achieved. This WILL run your avalon beyond its normal specification
so the usual warnings apply. When avalon-auto is enabled, the avalon-options
for frequency and timeout are used as the starting point only.
eg:
--avalon-fan 50
--avalon-fan 40-80
By default the avalon fans will be adjusted to maintain a target temperature
over a range from 20 to 100% fanspeed. avalon-fan allows you to limit the
range of fanspeeds to a single value or a range of values.
eg:
--avalon-freq 300-350
In combination with the avalon-auto command, the avalon-freq command allows you
to limit the range of frequencies which auto will adjust to.
eg:
--avalon-temp 55
This will adjust fanspeed to keep the temperature at or slightly below 55.
If you wish the fans to run at maximum speed, setting the target temperature
very low such as 0 will achieve this. This option can be added to the "More
options" entry in the web interface if you do not have a direct way of setting
it.
eg:
--avalon-cutoff 65
This will cut off the avalon should it get up to 65 degrees and will then
re-enable it when it gets to the target temperature as specified by avalon-temp.
eg:
--avalon-options 115200:24:10:D:1500:55
The values are baud : miners : asic count : timeout : frequency : technology.
Baud:
The device is pretty much hard coded to emulate 115200 baud so you shouldn't
change this.
Miners:
Most Avalons are 3 module devices, which come to 24 miners. 4 module devices
would use 32 here.
For BitBurner X and BitBurner XX devices you should use twice the number of
boards in the stack. e.g. for a two-board stack you would use 4. For
BitBurner Fury devices you should use the total number of BitFury chips in the
stack (i.e. 16 times the number of boards). e.g. for a two-board stack you
would use 32.
Asic count:
Virtually all have 10, so don't change this. BitBurner devices use 10 here
even if the boards have some other number of ASICs.
Timeout:
This is how long the device will work on a work item before accepting new work
to replace it. It should be changed according to the frequency (last setting).
It is possible to set this a little lower if you are trying to tune for short
block mining (eg p2pool) but much lower and the device will start creating
duplicate shares.
A value of 'd' means cgminer will calculate it for you based on the frequency
and is highly recommended.
Sample settings for valid different frequencies (last 3 values) for 110nm AVAs:
34:375:110 *
36:350:110 *
43:300:110
45:282:110 (default)
50:256:110
Note that setting a value with an asterisk next to it will be using your
avalon outside its spec and you do so at your own risk.
For 55nm AVAs, the usual values are 8:1500
Frequency:
This is the clock speed of the devices. For Avalon 110nm devices, values from
256 upwards are valid with the default being 282 and the maximum practical
being approximately 350. For 55nm devices values from 1000-2000 are valid with
1500 being the default.
Technology:
What sized technology ASICs are in use in the avalon, choices are 55 or 110,
corresponding to the nm technology chips in use.
The default frequency for BitBurner X and BitBurner XX boards is 282. The
default frequency for BitBurner Fury boards is 256. Overclocking is
possible - please consult the product documentation and/or manufacturer for
information on safe values. Values outside this range are used at your own
risk. Underclocking is also possible, at least with the X and XX boards.
eg:
--bitburner-fury-options <arg> Override avalon-options for BitBurner Fury boards baud:miners:asic:timeout:freq
This option takes the same format as --avalon-options. When specified, it
will be used for BitBurner Fury boards in preference to the values specified
in --avalon-options. (If not specified, BitBurner Fury boards will be
controlled by the values used in --avalon options.) See --avalon-options for
a detailed description of the fields.
This option is particularly useful when using a mixture of different BitBurner
devices as BitBurner Fury devices generally require significantly different
clock frequencies from Avalon-based devices. This option is only available
for boards with recent firmware that are recognized by cgminer as BBF.
eg:
--bitburner-fury-voltage <arg> Set BitBurner Fury core voltage, in millivolts
Sets the core voltage for the BitBurner Fury boards. The default value is
900. Overvolting is possible - please consult the product documentation
and/or manufaturer about the safe range of values. Values outside this range
are used at your own risk.
This option is only available for boards with recent firmware that are
recognized by cgminer as BBF. For boards recognized as BTB, see
--bitburner-voltage
eg:
--bitburner-voltage <arg> Set BitBurner (Avalon) core voltage, in millivolts
Sets the core voltage for the Avalon-based BitBurner X and BitBurner XX
boards. The default value is 1200. Overvolting and undervolting is
possible - please consult the product documentation and/or the manufacturer
for information about the safe range. Values outside this range are used at
your own risk.
Older BitBurner Fury firmware emulates a BitBurner XX board and is identified
by cgminer as BTB. On these devices, --bitburner-voltage is used to control
the voltage of the BitBurner Fury board. The actual core voltage will be
300mV less than the requested voltage, so to run a BitBurner Fury board at
950mV use --bitburner-voltage 1250. The default value of 1200 therefore
corresponds to the default core voltage of 900mV.
If you use the full curses based interface with Avalons you will get this
information:
AVA 0: 22/ 46C 2400R
The values are:
ambient temp / highest device temp lowest detected ASIC cooling fan RPM.
Use the API for more detailed information than this.

BFLSC Devices
--bflsc-overheat <arg> Set overheat temperature where BFLSC devices throttle, 0 to disable (default: 90)
This will allow you to change or disable the default temperature where cgminer
throttles BFLSC devices by allowing them to temporarily go idle.
BITFURY Devices
--bxf-bits <arg> Set max BXF/HXF bits for overclocking (default: 54)
In combination with the dynamic clocking on Bi*fury devices, this sets the
highest bit target that cgminer will aim for.
--bxf-temp-target <arg> Set target temperature for BXF/HXF devices (default: 82)
Cgminer uses dynamic clocking on Bi*fury devices to try and maintain the
temperature just below an optimal target. This option allows you to change the
target temperature. When actively cooled below this, the devices will run at
maximum speed.
--bxm-bits <arg> Set BXM bits for overclocking (default: 54)
Choose the overclocking bits for BFx2 devices.
--nfu-bits <arg> Set nanofury bits for overclocking range 32-63 (default: 50)
Cgminer by default sets the clockspeed on nanofury devices to the highest that
is still within USB2 spec. This value allows you to alter the clockspeed, with
~54 being the optimal but requiring a higher power or USB3 port.
Cointerra Devices
--cta-load <arg> (0 - 255)
--ps-load <arg> (0 - 100)
These are undocumented.
Drillbit Systems Devices
--drillbit-options <arg> Set drillbit options <int|ext>:clock[:clock_divider][:voltage]
* int/ext defines the clock source - default int. Not all boards support ext.
* clock_divider must be 1 or 2 with a default of 1. Bitfury only,
ignored on Avalon.
* clock is in MHz, on Drillbit range 80-250 with a default of 200,
recommended maximum 230. On Avalon range 500-1000 with a
recommended maximum of 800.
* voltage is ASIC core voltage in millivolts, available values vary per board but
default is 850 and the recommended maximum is 950 (Bitfury) and 1000 (Avalon.)
--drillbit-auto <every>:[<gooderr>:<baderr>:<maxerr>]
If supported by firmware and device, this feature allows cgminer to
automatically tweak each ASIC's clock rate up and down in to achieve
optimal performance.
* every - only required param, check each ASIC after each block of
this many work units. Recommended value 100.
* gooderr - the "Good" threshold is when less hardware errors than
this per "every" work units, the clock rate will be increased.
Default value 1.
* baderr - the "Bad" threshold is when more hardware errors than
this per "every" work units, the clock rate will be decreased.
Default value 3.
* maxerr - the "Max" threshold is when more hardware errors than
this per "every" work units (including pre-empting before
"every" work units is up), the clock rate will be decreased and
will not be increased again past this point. Default value 10.
BlackArrow Bitfury devices
--bab-options <arg> Set BaB options Max:Def:Min:Up:Down:Hz:Delay:Trf
Any option left blank or starting with 'd' will use the default setting
If there are not enough options, then the remaining will be left at their
default value
Max:Def:Min are the chip speed limits to allow, ranging from 52 to 57
Up:Down are the HW error % used to tune the chip speed
Up means if the HW error % is less than up, over a 5 minute period,
then increase the chip speed
Down means if the HW error % is greater than down, over 5 minutes,
then decrease the chip speed
Hz is the SPI clock speed to use
Delay is the us delay used between bytes for the SPI I/O - default 0
Trf is the us delay used between sends for the SPI I/O - default 0
Hashfast devices
--hfa-hash-clock <arg> Set hashfast clock speed (default: 550)
This will change the initialisation clock speed on all attached hfa devices.
Note that if instability is detected by cgminer and the device has to undergo
a reset, cgminer will lower the clockspeed on resetting it each time till the
value returns to the default of 550.
--hfa-fail-drop <arg> Set how many MHz to drop clockspeed each failure on an overlocked hashfast device (default: 10)
If you overclock your hashfast device with --hfa-hash-clock and cgminer detects
it failing to return hashes, it will restart it at a lower clock speed if
possible. Changing this value will allow you to choose how much it will lower
the clock speed or to disable this function entirely.
--hfa-fan <arg> Set fanspeed percentage for hashfast, single value or range (default: 10-85)
This changes the range of fanspeeds used on hashfast devices with firmware that
supports it. Note that the fanspeed will dynamically change to try and maintain
a target temperature with --hfa-temp-target but if the target temperature is
disabled, the fanspeed will remain static.
eg:
--hfa-fan 25-100
--hfa-temp-overheat <arg> Set the hashfast overheat throttling temperature (default: 95)
Cgminer will temporarily stop sending hashfast devices work once this
temperature is reached. Note that with the water cooling in these devices,
temperature recovery is likely to be very quick and the device will start
hashing again after only a very brief period.
--hfa-temp-target <arg> Set the hashfast target temperature (0 to disable) (default: 88)
On hashfast devices with firmware that supports dynamic fanspeed and die speeds,
cgminer will try to maintain temperature according to this target by adjusting
fanspeed and then if need be, throttle speeds on a die-by-die basis. Disabling
this feature will leave a constant fanspeed and die speed but will not disable
the temp-overheat feature.
--hfa-name <arg> Set a unique name for a single hashfast device specified with --usb or the first device found
This command allows you to specify the unique name stored in nvram on a single
hashfast device. This name can be queried from the API stats command and comes
up as "op name". Discrete names are used by cgminer to try to maintain settings
across restarts, unplugs/hotplugs and so on. If this command is used by itself,
the name will be given to the first hashfast device it encounters and then
cgminer will proceed to go back to regular mining. If you have multiple devices,
it is best to discretely choose the device you wish to use with the --usb
command. For example
'lsusb' on linux shows the following devices (297c:0001 is a hfa device):
Bus 001 Device 079: ID 297c:0001
Bus 004 Device 042: ID 297c:0001
If you wished to name the second device Slug you would add the commands:
--hfa-name Slug --usb 4:42
--hfa-noshed Disable hashfast dynamic core disabling feature
Newer firmwares on hashfast devices dynamically disable cores that generate
invalid data. This command will disable this feature where possible.
--hfa-options <arg> Set hashfast options name:clock or clock@voltage (comma separated)
This command allows you to set options for each discrete hashfast device by
its name (if the firmware has naming support, i.e. version 0.3+). Currently
this takes as option the clock speed alone or clock speed and voltage,
although future options may be added.
e.g.:
--hfa-options "rabbit:650,turtle:550@800"
Would set a device named rabbit to clock speed 650 MHz using default voltage
and the one named turtle to 550 MHz using a voltage of 800 mv. Starting the
device at a speed where it is most stable will give more reliable hashrates
long term and prevent it interacting with other devices, rather than depending
on the clockdown feature in cgminer.
Note: Setting voltage cause a board reset and hotplug event on cgminer startup.
Other undocumented hashfast command line options are for development purposes
only at this stage and serve no useful purpose to end users.
Hashratio Devices
--hro-freq Set the hashratio clock frequency (default: 280)
Bitmine A1 Devices
--bitmine-a1-options <ref_clk>:<sys_clk>:<spi_clk>:<max_chip>
ref_clk: reference clock in kHz (default: 16000)
sys_clk: target system clock in kHz to be set in PLL (default: 250000)
spi_clk: SPI clock in kHz (default: 800)
max_chip: [debug/testing] limit chip chain
Set 0 for fields you want to keep untouched to default, e.g.
--bitmine-a1-options 0:0:400
to only set SPI clock to 400kHz
Rockminer R-Box Devices
--rock-freq <arg> Set RockMiner frequency in MHz, range 125-500 (default: 270)
Note that only a limited range is likely to be accepted (usually 200-290)
