Not trying to dig some old thread here, but to help others.
Am running 10 of gridseed blade using cgminer 4.3.5 win7 x64bit, and mining eth at the same time.
Basic config for cgminer:
cgminer --scrypt -o stratum+tcp://gcpool.eu:3346 -u xxxx -p xxxx --scan-serial \\.\COM3.\COM4 --gridseed-options=baud=115200,freq=850,chips=80 --hotplug 80
pause
Hope it helps.
Is this config suitable to ether as well? I thought the blades could only do scrypt.
