I have radeon 7850 and have 350-450 KH/s, you cant put this in your cgminer file : setx GPU_MAX_ALLOC_PERCENT 100

hi indoril666
thanks for the reply

i didi this and gives me an error

setx GPU_MAX_ALLOC_PERCENT 100

"pools" : [
   {
      "url" : "stratum+tcp://world.wemineltc.com:3335",
      "user" : "chrischer.1",

"scrypt" : true
}

That setx GPU_MAX_ALLOC_PERCENT 100 is not inside cgminer.conf, but a command at the cmd.exe prompt

Inside the config file, use:

"intensity" : "20",
"lookup-gap" : "2",
"thread-concurrency" : "24000"
"gpu-threads" : "1",

or

"intensity" : "13",
"lookup-gap" : "2",
"thread-concurrency" : "8192"
"gpu-threads" : "2"

alongside the remaining settings

hi chrischer, start cgminer without configuration file, specify all required parameters in command line and later save the configuration file from cgminer menu
