Moonlander Two Setup on Linux (Ubuntu

Moonlander Two Setup Linux

Prep, Package Dependencies, Installation of Moonlander Two for Linux (Example: Ubuntu 16.04.1 LTS or higher)

Prep

This installation guide describes setup, configuration, package dependencies and the installation of mining software build based on a freshly Linux distribution (Ubuntu 16.04.1 LTS for example). You will need sudo rights. It’s not necessary to use root.

Very first steps: update and upgrade of system and reqired packages:

The following packages are mandatory to run BFGMiner for Moonlander Two:

  • libcurl4-gnutls-dev: URL transfer library für BFGMiner
  • libjansson-dev: JSON Library for BFGMiner

Pre-compiled binaries for Mac, Linux 64bit, Linux ARM, Windows 32bit und Windows 64bit spil well spil software sources will be available for download te the following public GIT repository:

Test if the Binary can be executed (vertoning commandline options):

Accessories

This USB Stick Miner requires a actively powered USB Hub which can independently provide Two A for each USB port. Wij have achieved good results with several USB Two.0 Hubs from Muuranker or Orico while Users reported several compatibility issues with USB Three.0 Hubs with Intel chipsets. For more details please check the following verbinding on bitcointalk.org.

This miner can operate with clock rates from 384 MHz to maximum 954 MHz. It computes inbetween Two.Five und Five.Five MH/s and consumes inbetween Two and Ten Watt.

Setup

The following directive will begin up the BFGMiner Software for Moonlander Two (example):

Alternatively you can run the enclosed Shell-Script:

The Pool configuration which is used ter the example above should be substituted by your own pool configuration gegevens. Please voeling your pool technicus or check the pool setup guide for more details. The example above shows a configuration for one of the best-known Litecoin Mining Pools.

The Clock Rate can be set with the following commandline parameter: -set MLD:clock=xxx.

Please note that this version of the miner has a immovable list of frequencies available to use below: 384, 450, 480, 540, 576, 600, 612, 625, 636, 648, 660, 672, 684, 700, 720, 744, 756, 768, 796, 832, 852, 876, 900, 924, 954.

The mining voorstelling depends on your Clock Rate and Core Voltage setup. You can calculate the average hash rate using the following formula:

  • Voorstelling ter MH = Five.66 * MHz
  • Example MH = Five.66 * 832 =>, Hash power of approx. Four.7 MH/s (+-5%).
  • The higher the hashrate, the fatter is the deviation from this average, caused by ASIC manufacturing tolerances.

Fine tuning

Please note: Voltage regulation should be done cautiously and ter very petite steps. Never set a votage wich is outside the below mentioned range. This would most likely harm the ASIC if you run at high voltages and high clocks for prolonged periods of time. Wij do not substitute miners which are bruised by inadequate clock rate and voltage settings.

If the miner does not begin with high Clock Rates or produces HW error rates of 100% it may be necessary to adjust the (core-)voltage.

The miner is tooled with two puny trimpods for voltage adjustment (one for core voltage, one for memory voltage)

Core voltage can be set inbetween 0.625 V and 0.91 V and memory voltage inbetween 0.65 and 1.05 V.

To turn the voltage up turn the pot clockwise, to turn it down, counterclockwise.

Make sure you have placed the stick horizontal and the USB end is facing left (you can read “FutureBit Moonlander” normally on the houtvezelplaat).

Setup of core- and memory voltage (see photos below):

Optimisation of clock rate and voltage

Basically, you can set anything inbetween the following screenplays:

  • Maximum hash spectacle with high clock rate and accordingly adjusted core-voltage at cost of a low power efficiency
  • Maximum power efficiency with low clock rate and accordingly adjusted low voltage at cost of a low hash spectacle

A combination of both screenplays will lead to the following “sweet spot”:

  • with a clock rate of 756 MHz and 0.725 V core voltage the ASIC operates close to the effciency maximum still showcasing a good hash spectacle. At “sweet spot” the miner can still be cooled adequately with the mounted fever submerge and fan.
