760 recognized, but r9 380 isn't? GPU-z shows both as active

Posted earlier about running an Nvidia and an AMD card in the same system. I'd like the 380 to mine all the time but I want my 760 to be unaffected as it's just for light gaming and browsing the internet. I have a dedicated rig coming together and it should be running early next week but I'd like to mine for the rest of this week and over the weekend while retaining the usability of my main machine.

Any ideas why ethminer sees the 760 but not the 380? I have a monitor plugged into both the 380 and the 760 and both are working simultaneously.

    Coz they have different mining software?

    the 760 works perfectly fine in openCL mode. I can't even get ethminer to only recognize the 380. I have to use --opencl-platform 1 to even get it to see --opencl-devices 1 which makes it see "Tonga" as the GPU. Then I get the clCreateBuffer(-61) error.

    for anyone wondering I am using the newest version of Ethminer downloaded from this page http://cryptomining-blog.com/7603-the-latest-ethminer-0-9-41-genoil-1-0-6-for-windows/

    I have the 380 in the uppermost slot on my motherboard and the 760 in the 2nd 16x slot. Motherboard is the Gigabyte H170M-DS3H

    Finally got the 380 running on it's own but I am only getting 15mh or so from it. Was getting 23mh while just running it as a single card without the 760 but I guess I'm gonna have to run it like this for the weekend.

    Here is my batch file
    setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 95 export GPU_SINGLE_ALLOC_PERCENT=100 ethminer -G --opencl-platform 1 --opencl-device 1 -F http://us-east1.nanopool.org:8888/0x4a41e7b14fc18dfbe5b05fb3dd822b0ff476cbde/miner1 --cl-local-work 256 --cl-extragpu-mem 0
