Hi everyone,

I've just finish setting up the following rig;
* Win 10
* 2X Sapphire - Radeon RX 580 4GB NITRO+
* 2X Sapphire - Radeon RX 580 8GB NITRO+
* radeon-software-crimson-relive-17.8.1-win10-64bit-aug18 drivers
also tested with non-whql-win10-64bit-radeon-software-crimson-relive-17.9.1-sep7 and got same result
* PolarisBiosEditor-master one click bios patch

When I only use one GPU at a time I can oc and get 29Mh, but drops to 24Mh when I add more GPUs and can no longer oc.

Has anyone encountered this issue?

Thanks!
