Expected behaviour. The stock RX 480 does not hold it boost clock with 0% power limit, so a overclocked model will show the same fluctuation unless you increase the power limit.

100% gpu load issue seems to be fixed with latest driver sset which is good news, however it seems that sometimes the gpu fans decide to stop working and I try using trixx to change the speed and it says as 0 and temps skyrocket until I reboot. A reboot temporarily fixes this and allows fan control until it happens again. Anyone having similar issues with the fans?

Im getting the same fluctuations at stock or overclocked, both with +50% power limit. And it seems anything i do on an idle desktop is pushing the GPU clocks up and down, from moving the mouse, right clicking desktop and playing Twitch streams even with hardware acceleration disabled in Chrome.
I just want my CPU to do all these things and the 480 just to do my gaming tasks, is that too much to ask from an RX 480 and its drivers?
This must be why 0db/0% fan speed is giving high temps, because the GPU is being utilized for even the smallest tasks done on the displays that the 480 is hooked up to, i have 1 monitor hooked up to my 480, the other 2 are hooked up to my 6700K's iGPU and when i do stuff on those other 2 monitors the 480 is fine with no fluctuations in clock speeds.
Try and replicate this and you might understand what im getting at here.

Perhaps i misunderstood your post i quoted, but you said the clock does not stay at full speed unless you increase the power limit when under load?
If you can show me a video of what you mean when idle that would be helpful. I can do a little more investigation to see if this is a bug or expected behaviour. Some clock fluctuation is to be expected as Windows uses the GPU, even when the system is seemingly idle or not much is happening.

The fluctuations i get are the loads bouncing around anywhere between 0% and 100% while gaming even though the clocks stay maxed at whatever i overclock them too, which in turn i think is causing stutters sometimes in games. Im sorry if i didnt explain this properly.
As for a video, i'll see what i can do later or tomorrow.
I just never had any of this at all with my 7950, same system on Windows 10 too. This is why im baffled why the 480 is being utilised in pretty much everything i do on the display it is hooked up to.
I kinda dont think a clean driver install with DDU is gona help, and i dont like to use DDU unless i have to.
If someone else with a similar setup to me using iGPU along with a 480 can test, that would be great.
Edit, The fluctuations i was talking about was the Load % that i see in GPU-Z

That is normal for GPU usage to fluctuate that happens on my AMD GPUs. If you believe that is causing stuttering then download MSI AB and enable unified GPU usage monitoring. If you stop seeing stuttering after making this change then perhaps it is related.

Sounds like an issue with GPU-Z, try MSI AB.

As you guys are unanimously saying that these are a good driver set and I trust you all with my life then lets get downloading and updating to 16.9.1 
thats normal. it just means the game doesn't need the gpu at 100% all the time,

I'm getting a black screen with just the mouse cursor when trying to install the new drivers. Tried leaving it to see if it is the normal flickering you get when installing a driver but seems permanent. Have to then restart in safe mode to roll back the driver in order to get windows to boot. Very strange as never had an issue before.
My cat exploded and the wife ran away with the milkman but apart from that the drivers appear fine!As you guys are unanimously saying that these are a good driver set and I trust you all with my life then lets get downloading and updating to 16.9.1

Msi afterburner can't read temps etc on my sapphire card?

im still on 16.6.2

Im still on the 16.3 Hotfixes

they actually seem pretty decent. Desktop flicker when exiting or alt+tabbing out of a game with Freesync seems to be a thing of the past. I still get some flicker during game loading screens or menus, but can live with that for the time being.
Performance seems good, installation was fine etc

I stopped using MSI AB months ago because if it was on my clocks varied even if MSI AB wasn't touching the settings, Keeping it off fixed the problem for me.
A few days back I installed the new MSI AB Beta and the clock fluctuations returned when MSI AB was on, turning it off solved it again.
A bit odd I know.
Basically Gpu-z reports 100% solid clocks for gaming loads with MSI AB turned off, If I turn it on they fluctuate dropping 2 or 3 hundred from 1040mhz to the 8 or 9 hundreds.

I just ordered a Freesync panel so I'm looking forward to experiencing it for the first time, I have Witcher 3 and Metal Gear solid both installed and unplayed so I'll try it out with them first.

you sir are in for a gaming treat then. I would never ever game again without Freesync or Gsync
Do you think it would be possible for AMD to incorporate a way to change the maximum pixel clock over dual-link dvi so those of us with 100hz+ dual-dvi monitors wouldn't have to resort to workarounds? Can't get anything higher than 330mhz without a patch, and there's really no max limit stated by anyone so really not sure where the 330mhz comes from (there's a recommended value of 165hz for single link dvi, but none for dual-link and I can attest that up to 500mhz works for a lot of us). Oh and while I am at it, add nearest neighbor scaling instead of the methods used right now (would mean that each pixel at a resolution of 1080p would take up 4 pixels on a 4k display). Nvidia are working on incorporating this into their drivers, and I hope AMD would too (pretty sure everyone would want this added to the drivers as it would allow people to buy 4k monitors and play at lower resolutions without an insane amount of blur!).
AMD/ATI Pixel Clock Patcher (broken since 16.9.1 due to some unknown reason, so I'm currently stuck at 85Hz)
Integer scaling (nvidia forums, just to show you that people really want this feature!)
EDIT: Heck I wouldn't even care about the pixel clock thing if you could add different scaling algorithms! Imagine how many people want to buy a 4K monitor, but don't because they would basically have to buy a Pascal Titan to run any games at its native resolution or have to choose between 4k at <30fps or a blurry mess that just looks awful.
Here are two more threads about the subject, and I am sure many many people would be willing to switch from nvidia to amd if amd incorporated such a feature before the former:
AMD's forums
[H]ardforum
Nvidia's response

The latest driver actually gives a performance boost of upto 10% in some games even though it's not mentioned in the release notes. I tested Doom and it appears to be getting a minimum of 90 fps where it was previously getting 83 fps. Fallout 4 is not dipping below 52fps now outside the Corvega power plant and maintains 60fps most of the time.
