Hi
Firstly my relevant specs:
VGA: R7260X-DC2OC-2GD5
MB: ASUS MAXIMUS VI IMPACT
CPU: Intel Core i5 4670

So I've noticed in the Catalyst Control Center, that after awhile (from half to 1-2 hours) my graphics card runs its memory on 150MHz instead of its maximum 1750MHz.
I frequently get tke "Amd driver stopped working and has recovered" when playing games, or watching videos, and after that, the clock of the memoy remains low.
But now I've noticed, that I don't have to play. Just leaving the pc idle for an hour or so, and starting a more graphics wise demanding program, also results the same problem.
Occasionally black or white lines also flash in horizontally across the screen.
Also the Catalyst driver (the newest beta) doesn't seem to recognise the chip only that it's a R7 200 series.

What I've already tried:
-reinstalling the driver
-reinstalling windows (8.1 64bit)
-resetting the CMOS
-replugging the power cable on the graphics card.

Thanks for the help!

Looks like a bad card but try the WHQL certified drivers first.
And also check the temperature/fan speed with GPU-Z, maybe the fan has been jammed by some piece of detritus from assembly (detached labels from the PCB have been know to do this).

I did try installing Catalyst 13.9, but the one on the disc didn't even detect any graphics card and the AMD version aborted install, telling it hadn't detected any AMD video cards.

In CCC the GPU temp was around ~70°C when running starcraft2 on ultra settings, 40 on idle. After the error, memory down to bottom, GPU skyhigh, temp 70°C + until 80°C but it stopped there, because the fans kept speeding up until 40-50% load, so I don't think there would be a problem with the fans. (This card has one silent beefy cooling, that's for sure)

Thread necro lol

But no,chances are its not a faulty card. The problem is PowerPlay.

PowerPlay is software that reduces clock rates when they're not needed,like on your desktop when idle,and increase them when you do need them,like during gaming.
But its sensitivities are/were completely off. I never got full Core clocks during games,typically 400ish MHz out of the 1100 it should be.

my copy/paste solution from another thread.
If you dont already have it,get MSI Afterburner

Disclaimer: do not use numeric values shown in screenshots,tailor your clocks for your card.

Use the sliders to set your stock clocks which should be 1100MHz core and 1625 memory(reference 260x),click apply then select save then click Profile 1.
Next drop all the sliders to the minimum value,apply then save to profile 2.
Then go into "Settings" and find the "Profiles" Tab in the top right and save your 2d and 3d clocks to the appropriate profiles, like so.

Next bypass PowerPlay (the source of your sticky clock woes)

Your old 2d clocks were most likely 300 core 150 Memory,now the lowest they'll go is half the default values.
But atleast this way your full Core Clock(and potentially more!) will be used in games 100% of the time.


After you apply those settings and give a full system restart,you should be good to go.

Edit: And set a Custom Fan Profile to stop all that over heating.
