@claymore my RX480 4Gb can not run at i8 with 11.1. Get insufficient memory message. But my Hd7970 with 3Gb runs fine using asm i8. I hope this is just a bug and will be fixed in the next release
Insufficient memory message is generally not related to the available memory on your GPU but rather the size of the swap file on your HD/SSD. Make sure you have it set to 16GB+
GPU #0 is going to use too high intensity (

, not enough memory, intensity value reduced (7)
GPU #0 algorithm 2, intensity 7
GPU #1 is going to use too high intensity (

, not enough memory, intensity value reduced (7)
GPU #1 algorithm 2, intensity 7
GPU #2 is going to use too high intensity (

, not enough memory, intensity value reduced (7)
GPU #2 algorithm 2, intensity 7
GPU #3 is going to use too high intensity (

, not enough memory, intensity value reduced (7)
GPU #3 algorithm 2, intensity 7
Is that swap file related or gpu related?
