These ship set to
--avalon-options 115200:16:D:1400:55 (1400Mhz)
if you set
--avalon-options 115200:16:D:1500:55 (You're overclocking from stock by 100 Mhz)
******
The values are baud : miners : asic count : timeout : frequency : technology.
******
From the CGminer ASIC-Readme file.
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. (Our devices are 2 module devices = 16 miners)
Asic count:
Virtually all have 10, so don't change this.
Timeout:
A value of 'd' means cgminer will calculate it for you based on the frequency
and is highly recommended.
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. (Ours shipped @ 1400)
Technology:
What sized technology ASICs are in use in the avalon, choices are 55 or 110,
corresponding to the nm technology chips in use. (we have 55nm chips)
Many thanks!
