I don't understand, I think you're confused between clock speeds and launch parameters 2) ethminer.exe -G -F http://127.0.0.1:4052/miner/17/Lightning --farm-recheck 500 --cl-local-work 128 --cl-global-work 16384
First stap : decrease core 1000 and memory 1500
Second : at .bat file use ethminer.exe -G -F http://127.0.0.1:4052/miner/17/Lightning --farm-recheck 500 --cl-local-work 128 --cl-global-work 16384
