ETHMiner help

[rocketron]

Hi everyone,

I am trying to get Ethminer to only use 3 of my gpus and leave 1 free for other tasks.

I tried --opencl-device 1 2 3 and --opencl-device 1,2,3 and it will only use 1 gpu.


is there a command i can use to display device id ?

I cant understand what is happening here lol others say to use the commands a above to set what cards to use and it works,

this is what I get if I just use the defaul -G command


Found suitable OpenCL device [Tahiti] with 3221225472 bytes of GPU memory

You need to use a hex editor, Copy ethminer.exe rename to ethminer2.exe (change it back after these steps) Edit with hex editor and search for "full-" and you will see something like "full-R%u-%016llx" then change "full-" to "ful2-" and save it.

Thanks very much pal. I will try this later

hi m8,

I tried this and ethminer said it wasnt a valid application,

can you screen shot yours?

thanks

Just dont use the opencl-device argument. If I leave this out of my command arguments, it just uses all gpu's it finds.

Cheers for reply. I do this,  but i want to leave my 1st gpu free from mining and use the other 3 for mining.
