Santor I dont quite get the syntax on the settings for freq

--freq=850 --gc3355-freq=/dev/ttyACM0:900

Why is freq 850 used then 900

Thanks

--freq=850 is the setting the clock speed for all the Gridseeds.
--gc3355-freq=/dev/ttyACM0:900 is setting the clock speed for a specific Gridseed. If you have multiple, you can set them like so: =/dev/ttyACM0:900,/dev/ttyACM1:850,/dev/ttyACM2:950

You can use either. I don't know what'll happen if you use both though, presumably the --gc3355-freq is more specific and will override whatever is set on --freq. If this is the case, you can set a default clock speed for all the Gridseeds and override a few that need to be set differently.

And if you want to be more specific, you can set the frequency of a specific GC3355 chip:
Code:
--gc3355-freq=/dev/ttyACM0:900,/dev/ttyACM0:875:4
-> that will set the frequency of chip 0-3 (0-3 & 5-39 for G-Blade) of the miner @ ttyACM0 to 900, and chip 4 will be set to 875.
