so had a terrible time setting this one up but think I have some thing stable now for these 2 cards
xFx core 4GB settings
@27Mh using 136w
@wall 125w
@cardSapphire 8GB settings
@27Mh using 130w
@wall 119w
@card Hope this helps you get a good MH out your cards will less effort than I put my self though

How are you guys saving your settings? Making a profile attached to the miner exe?
From your screenshots I'm assuming you're using Crimson to change them, but when I try changing the Frequency to -16.5%, it automatically moves back to 0! Same with Voltage Control, it says N/A on all States and wouldn't let me change anything. Only things I can change are Memory, Fan, and Temperature.
I'm using 2 XFX 480 and 1 Gigabyte 480. Here's a screenshot: (can't change the Frequency so I set it back to Dynamic for now)
Would you happen to know why this is happening?
Regardless, I'm getting roughly 74 MH/s just with temperature and FAN tweaks out of my 3 cards so I shouldn't be complaining.
Once I get my remaining 3 cards, I'll post a couple of pics of it. My mining+gaming rig looks pretty sick with a 0.7 meter server rack!
Only complaint is that I can't crossfire, since a RX 480 occupies "two" PCIE space (1 slot) so I had to plug one RX 480 on the mobo, and the rest via raisers.
Thanks for your/parity's efforts boysie!
Do you think you can put yourself thru trying to get that to work in Ubuntu 16.04? Those of us that have it working get about 16Mh/s and thousands of GPU faults per second.
Ubuntu 16.04 LTS
AMDGPU-PRO v16.3 (which uses OpenCL v1.2)
parity v1.2.2-beta
ethminer v1.2.9
ASUS 8GB RX480
See this thread for trying to mine with Ubuntu 16.04:

Hopefully ethOS will get there soon and provide this for people to purchase.

PS: if you have the hardware you are only 20min away from it fully working on windows and that's point and click for any noob can setup....to me it seems silly to make this harder than it needs to be ...given all other cards can not under volt on Linux and you must do this with these cards else you will cause the power fright between the mem and the gpu. you can repro it on windows by leaving the power set to default or auto and only changing the clocks/mem, the only way to over come it is to raise the maxpower% and then this card eats power like your wouldn't believe while still getting shit perf. I've tried for many hours to get a better clock/mem/MHs but it looks like this is near the sweet spot at least.
The Radeon™ RX 480’s power distribution has been improved for AMD reference boards, lowering the current drawn from the PCIe bus.
Or is this some other issue that you're referring to?
Thank you and you are right in that windows is much easier. I'm new to Linux so I'm trying to force myself to learn it via this project and others.
In the link to that other thread they solved my issue and are able to adjust the power settings (don't know if that is directly via voltage).
The solution to my problem (for others reading this) was I needed the most recent branch of ethminer, which is genoil branch "110" that compiles itself to version 1.1.7.

Now I have no errors in the logs and I'm getting 22Mh/s.
