side note: how fast are 280x gpus supposed to be on x13?
I am getting 2.5MHs + using -g 4 -w 128 --gpu-engine=1050 --gpu-powertune 0 --intensity 18
I have some Sapphire Dual-X 280x and I'm getting 2.450 without spending time to find the best hashrate. Here's my config:
-g 2 -w 256 --gpu-engine 1090 --gpu-powertune 20 -i 16 and voltage: 1.200
