have not yet tried the double dash will do tonight but I have 3 boards 16 bitfury 2 at 100ghs and one at 42 ghs do i enter it like this 115200:96:10:50:256
Thanks for your help
Yes from the cgminer 3.4 readme:
eg:
--avalon-options 115200:24:10:45:282
The values are baud : miners : asic count : timeout : frequency.
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.
Asic count:
Virtually all have 10, so don't change this.
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
Sample settings for valid different frequencies (last 2 values):
34:375 *
36:350 *
39:325 *
43:300
45:282 (default)
47:270
50:256
Frequency:
This is the clock speed of the devices. Only specific values work, 256, 270,
282 (default), 300, 325, 350 and 375.
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.
