set also supports running blades off a Raspberry Pi directly or with USB Dongles. You can also set the frequency per board by specifying the tty port: MHz increments (driver will default to 352 MHz if these conditions are not met).įrequency is set with the following -set option: The driver supports custom frequency settings in the range of 200-400 MHz in 16 (the four ttyUSB ports are auto detected by all) S ALC:all -S ALC:/dev/ttyO1 -S ALC:/dev/ttyO2 -S ALC:/dev/ttyO3 To detect all the blades you need to manually probe it The driver has been designed to run each of the 8 blades inside an AlcheMistĢ56 as a separate miner. This driver requires the latest FPGA firmware flashed on the blades (stockįirmware has major bug and won't run properly with this driver). Need to experiment with a good queue setting to control how much work BFGMiner Timeout/clock/reg_data combinations, however!Īdditionally, since the controllers are underpowered for these devices, you may You can probably use either one, but the 350 MHz clock performsīetter than the 200 MHz clock. Notice how there are duplicate settings for timeout, clock, reg_data, and NOTE: These are NOT valid BFGMiner options! "bitmain-voltage" in the /config/nf file. You want to lookĪt the "bitmain-options" from the command line, and the "bitmain-freq" and Time, but can be determined from the stock cgminer's options. The meaning of each of these options are not documented individually at this Note that reg_data is optional for S4 and S5 and will be calculated from clock set btm:clock=350 -set btm:reg_data=0d82 -set btm:voltage=x0725 S bitmain:auto -set btm:model=S5 -set btm:layout=32:8 -set btm:timeout=3 None of the device attributes are autodetectedĪt this time, so you must also tell BFGMiner this at runtime with a series of WhenĬonfiguring, use the -enable-bitmain option to build the 'bitmain' driver used Series (both USB and blades), a large variety of Bitfury-based miners,īitmain's Antminer S5 and U1-3, Butterfly Labs' SC range of devices, HashBusterīoards, GekkoScience's Compac USB stick, Klondike modules, and KnCMiner'sīFGMiner must be compiled for and run on the embedded controller. But if you do, solo mine and hope for the best.Currently supported ASIC devices include Avalon, Bitfountain's Block Erupter Take my advise and don't buy either of these. Unless you solo mine bitcoin and hit a block, you will ALWAYS lose money with these because of the power they use. Just google what coins use this algorithm. Now moving on to your links, your looking at ETC there. Anyways, they were compatible with Nicehash a year ago the last time i looked into it, can't guarantee for nowadays. They do work just fine, i have a few of the GekkoScience that I bought when he developed them, but that was more to support his work, because he's kinda cool, at least from what i know of him on the forums. So to answer your first question, you can use them to mine any SHA256 coin, not just bitcoin, however you'd be lucky to make pennies. They are grossly obsolete, but if you already have them then well welcome to the party. To start with, if your considering buying either of these to make coin, don't bother.
