Previous version software supports dual mode. If you use previous software on Windows, you can do dual mode with following commands.
We have to start two cgminers. One is for BTC mining. Another is for LTC mining. This two process use same exe file.
Start BTC mining with command:
cgminer.exe --dualminer-pll 500 --dualminer-btc 64 -o stratum+tcp://btc.give-me-coins.com:3335 -u xxxxx -p xxxx -S //./COMxxx
COMxx is the device name on Windows. --dualminer-pll is for clock freq. --dualminer-btc is for how many units you want to open
Start LTC mining with command:
cgminer.exe --scrypt -o stratum+tcp://ltc.give-me-coins.com:3333 -u xxxx -p xxxx -S //./COMxx
--scrypt is for scrypt mining.
If you just want to mine LTC, you can use:
cgminer.exe --scrypt --lo -o stratum+tcp://ltc.give-me-coins.com:3333 -u xxx -p xxx -S //./COMxx --dualminer-pll 850
The --lo param forces cgminer only mine LTC. In LTC only mode, only one cgminer is needed
The version on github doesn't support this dual mode. We will add dual mode support by next Wednesday. After this work done, you can do a dual mine with just only one cgminer.
Thanks for your quick reply dualminer_3,
that helps a bit more to understand the dual mining configuration in general and I hope this will be more clear in the future, especially for non windows systems.
But as the main purpose of this chip is scrypt mining, what is the best way to mine scrypt-only so far on linux?
* does the position of the hardware switch matter at all?
* and which mining software is currently working for that on linux ? cpuminer/cgminer ? which version or fork is recommended?
Cheers
