I have the same cards with the same problem. On slot 1 pci-e 3.0 card runs 12 degrees hotter than the other on pci-e 2.0. Voltage is locked unfortunately. I hope we find a solution soon.

is there any method to unlock voltage?

i have done that with trixx for sapphire. Maybe it will work with your card. My card is Sapphire Vapor-X R9 280x

I need some help with the config. I only get about 560 kh

here my config
cgminer -o stratum+tcp://coinotron.com:3334 -u ** -p ** --scrypt -I 20 -g 2 -w 256 --thread-concurrency 8192
1038 GPU
1500 Mem.

Big Thanks

set -I 13. also on your oc software, change clock speed from 1100 to 1050. And my gpu memclock was by default set to 6000. So I left it untouhced. See if that works for you.
