Can't Mining with 2xRX 480

I'm trying to mine with 2xRX 480 in the same rig but I fail in something. Windows 10 detects both GPUs. If I try to mine with Ethminer or Qtminer i have the "No GPU device with sufficient memory" error. If I list the cards on qtminer or ethminer they found both with 8g of memory.

I only can mine with this sentence but qtminer only detect one card:
qtminer.exe -s -u mywallet.rig3 -G --opencl-device 0 --opencl-platform 1

If I miss --opencl-device 0 part, only detect one card too.

C:\Users\Miner\Desktop\qtminer>qtminer.exe -s -u walletadress.rig3 -G --opencl-platform 1
Qt: Untested Windows version 10.0 detected!
i 21:35:34|main Connecting to stratum server : 4444

i 21:35:34|main Login to stratum server successfull

Any help?

I tried setx settings and It doesn't help either.

Solved mining with Claymore.

    Set pagefile to 8 GB at least. Delete obsolete DAG's.

    You have onboard video enabled? You try --opencl-platform 1 ?

    I wouldn't use qtminer at this point. It hasn't been updated pretty much since release. Genoil's latest branch of claymore's dual miner seem to be the prefered miners these days.

    Do you have the latest AMD drivers installed. Previous to the latest Drivers you had to follow a few steps to get your Rx 480 to be able to mine with. With the latest AMD drivers you don't need that anymore. I would us DDUI to do a clean uninstall of all amd drivers, then install the latest AMD driver. Set page file to at least 16gb also. Hope that fixes your issues
