Afterburner does not work (does not open) in my 13gpu 1080ti system, I use Asus GPU Tweak 2 and can make OC to all the gpus without any problem. Maybe it should be integrated into Awesome Miner, too. Another option could be nvoc utility (
https://github.com/deathcamp/NVOC) to oc mem and core; "nvidia-smi -pl xxx" for the power. A bat file could be created from all of these.
Seconded. Afterburner just crashes with 12 GPUs, works fine on my 8 GPU rigs. I too have resorted to using NVOC and nvidia-smi -pl to set my rigs with a bat file. This works fine for regular managed miners as they have the ability to run command before starting to mine. It's more of an issue for the profit switching miners, would need some way to run different command per algorithm.
