don't use a comma between the devices.

--opencl-device 0,1

write:

--opencl-device 0 1

this isn't supported with the ocl miner. i've got it only in the cuda miner currently with --cuda-devices x y z.
i'll put it on the backlog for 1.0.x

yeah, -G does all gpus and -C for all cpus.. sometimes the ethminer program gets a hiccup now and then and its only temporary if it did happen... --opencl-device is best used to specify a certain opencl device.. for an example a amd apu and an add on opencl video card ..-- opencl-device 1 will just use the add on adapter will it disable gpu 0.. the integrated

if you have 2 gpus, you dont need to specify them

just do

ethminer.exe -G if its AMD.

I discovered when I was using the command line below that I was losing the hash power from both GPU's.

ethminer.exe --farm-recheck 200 -G -F http://127.0.0.1:8332/: -G --opencl-device 0,1 --verbosity 9 2>&1 | wtee ethminer.log

I tested this by using ethminer.exe -G -M --opencl-device 0,1

sure enough I got hash power from one GPU only!

I than just used ethminer.exe -G -M

I than saw both GPU worth of hash power. Am I doing something wrong with the --opencl-device command or is this switch totally broken?
