R9 390x OC now blue pixelation

[gtr22]

Yesterday I overclocked it to 1150 clock with 50% power limit, 1.0 core voltage. It was running around 85c. They can run hotter I know. My cpu was oc to 4.2 ghz, around 75c. After 2 hours during gameplay the screen would go black for 2 seconds. Then later a blue pixelation started covering the screen. Turned everything back to default. Installed the new AMD driver, today the same problems are happening without overclocking.

Anything else to try, test?

Did you use something like DDU to completely strip off the old driver before you reinstalled?

 

[gtr22]

Yes, I always use amd uninstaller.

I'd definitely try a fresh install of drivers using an application like DDU, if that doesn't work you may have fried the GPU. Exactly what model 390x is it?

DOWNCLOCK to test if it's a hardware issue.

Choose 90% of the default GPU and 90% of the VRAM value. If that works, then increase until it has issues then back off a bit (go back to 100% for the GPU if it's fine. same for VRAM). Your card may have been on the verge of having issues then overclocking messed it up.

Since the problem started BEFORE changing the drivers I don't think it's a driver issue.

Also, are you CERTAIN your clocks, voltage etc are back to default?

I use MSI Afterburner, it's an MSI card. I have used this setting for a while, with Fire Strike tested it, no problems with games. It happened on Rainbow 6 Siege and The Division, it runs perfect though on BF4 no problems.

If I were in your shoes I'd take the cooler off and physically inspect the whole card. Look for any popped capacitors. Unless the overclock is still somehow getting applied, it sounds like its more of an issue with the hardware.

I seriously doubt the card would function properly in 2D mode if there was that level of damage.

It sounds like you are right on the verge of failure, or possibly the memory causing corruption isn't accessed during the games it is working on.

Either way, make sure your POWER TARGET, frequencies etc are ALL back to normal. If it still fails then drop both memory and frequency as suggested to 90%. If that works raise one at a time until failure then back off until it is stable.

All games run normally. Except 1, it has the blue shadowing, screen goes black for 1-2 seconds. It runs also normally.
