The weird thing is, when you do the PCI-Express render test in GPU-Z, the Fury will clock to it's maximum speed
Clean Install AMD Graphics Drivers This is how you clean install so no need to re install Windows anymore
The latest drivers are the beta ones, the fix a few driver issues. You'll find them on the download page.
Clock drop would seem to be related to Windows 10 specifically, but with any card maker as well. Scrolling through a few forums and its an issue relating to Windows that can be sorted but requires a lot of work, take a look at your Event Viewer, I'm still trying to solve it myself. 95% of the time I'm okay.
If you can stand the noise of the Fury with all 3 fans then put the power up to +20%, should be fine as its just the Fury Pro chip. Check if you have Frame Rate Control on, if it is it will clock down when it hits 60fps, if so disable it. Turn off vsync. This will treat your GPU like its on a Benchmark, so 100% ish depending on the API.
Hope this helps.
I know how to install and uninstall drivers, this isn't the first time i've done it
The problem was that even after uninstalling Crimson there were still some stuff off it left, which you just couldn't get rid off (like the new Crimson control center : it just wouldn't uninstall)
As said in the start post : I already tried upping the power : it doesn't work, the GPU still won't go past 600MHz in-game (and not get warmer then 37 degrees)
I never have V-sync or frame control enabled : it's the first thing I check if they are turn off.
Did you use DDU on the link? This boots into safemode and removes literally everything. And preventing Windows from installing drivers is important to. But it much be another reason, not sure why it didn't delete it. Its almost flawless.
This would be my suspicion for clock drop, something still left over. What drivers are you using now? Are you still hitting 60 and only 60 in Fallout? What other games are you getting the clock drop? I don't know anything about Arma3 so can confirm. I'm sure you know but the render test will use all the HP of your GPU, power saving on or not. Just getting an idea of possible problems.
I haven't used DDU.
Normally I uninstall the drivers via Windows App/program and after they are uninstalled I use CClean to make sure that there aren't any registery links left.
With Crimson even the AMD cleanup utility couldn't coulnd't get rid of everything :
Now I'm using the "old" AMD Catalyst 15.11.1 beta driver again.
With this driver there are no GPU clock drops and I get fluid grafics with ARMA and Fallout.
The problem is quit simple : it's Crimson.
I'm no software enigeneer but it looks like Crimson keeps the GPU in power save mode and won't let it run full throttle.
As pointed out in the opening post : there are alot of people who have these problems
That's your problem then, when you say you know how to install and uninstall you didn't read the linked page that explains the issue with using just Windows Uninstall and things like CCleaner. Next time use it. Its most probable you had left overs from whatever you had running last. The fact you couldn't uninstall Crimson was a sign CCleaner doesn't do everything. The first Crimson driver had a few issues, like fans and power saving (clock drop).
But its good your up and running now. But again when you do need to upgrade your drivers for the next new game, API or whatever to follow that guide. Pease remember to mark your thread as solved.
Just for fun, seeing it's a fresh Windows install right now :
I removed Catalyst 15.11.1 with DDU, did a restart and installed Crimson.
Did a benchmark with ARMA 3 : just barely hit 30 fps while nomally with Catalyst it hit 48 fps.
The GPU didn't go to 1040MHZ (stopt around 725Mhz) but it did heat up to 68 degrees WITHOUT the fan's kicking in.
In Fallout 4, it starts at 60 fps and drops off to somewhere around 20/24 fps ,goes back to 60fps and drops off again
I'm all out of ideas and time, someone else might be able to suggest something. Hope it gets sorted.
Okay, I have to be honest, maybe you were on to something.
When using Crimson without changing any settings within overdrive ARMA gets stuck on 30 fps and the GPU heats up to 60+ degrees without the fans doing anything
I've just installed Trixx (Sapphire's videocard tuning thingy) and made a custom fan profile.
Next up , in Crimsome Overdrive i've put the power limit at +7%
Just did a benchmark and hitting 53 fps , that's on ultra settings with a viewing distance of 3400.
So, it seems to be working.
Not precisly how I would have preferred , but lets try it for a couple of days and see how it goes.
Don't know yet if it will still crash when you're watching video files, gonna try that as soon as possible
That's a relief to hear. Remember as well if you do run into problems now or ever to report it using Report Problem button in Crimson, its the only way AMD will know and then can work on a fix for the next (or later) driver. I hope it hold up for you.
