All my 6x480 rigs are running creators update, v9 miner, 16.6 drivers.

Flawlessly 

Put the blame on something else, creators update works like a charm!

Is it useful for a mining rig? Maybe not... but it works!

16.12 I guess.

Which driver should I download?

I have one rig which takes about 60 seconds to start mining after claymore opens. it has 7 470s.

I have a rig with 5 480s and 1 470 and it starts very fast.

any ideas?

this is not true at all, i get about 2-2.50$ more a day with 9 vs 8.1

yes it fluctuates some.. but not enough to be a problem. the boost in dcr is well worth it.

Is the new ROCm Linux driver supported? How is the hashrate on 480? Is it better with ROCm, or with amdgpu-pro?

Than either the -asm 1 is not working for you because the boost is tremendous!  You may want to verify that asm is enabled and your speed is faster than it was before.

Hey guys, sorry for a stupid question but i'm pretty new to mining so i can't really understand a couple of things. Can you tell me the ups and downs of dual mining? Is it better than solo mining? Hows gpus serving time? is it shorter if you're dual mining? Huge thanks

somewhere between 20-30

UP: more money
DOWN: more power, more heat, more noise

Dual is better if you are after money, for anything else is worth.
