Artifacts on screen after Gpu overclock (rx 470) using MSI Afterburner

Weird artifacts with differant colours showing on screen after overclocking.
They only appear when I'm using my mouse/keyboard when im at desktop, google chrome or anything similar. (NOT IN GAMES OR WHEN RUNNING STRESSTESTS).

How this happend:
I overclocked Core Clock, Core voltage, raised power limit to max and put 75C as max temp.
After this I started raising Memory Clock, I kept stress testing each time I raised it and it seemed stable as ever. When im at 1850 (stock is 1750) I ran a last stress test and now I have artifacts on my screen.

What I've tried so far:
Stopping the overclock
Downclocking speed and voltage
Raising voltage and leaving the rest at stock speed.
Turning everything on and off
Pulling out cables and putting them back in.
Letting everything cool down overnight.
Doing a pc reset to the date that I first booted my pc and installed the drivers and nothing else.

Sinse everything is fine when gaming or running stress tests I believe nothing is broken but I don't know much because this is my first time overclocking.
The max temp the GPU got was 73C and this was ages before I got this problem.

Questions:

1: Is my gpu broken?

2: If it is broken can I return it and get a refund?

3. Can updating drivers or MSI afterburner (if possible) solve this?

4. Is overheating the only way to destroy a GPU while overclocking and if so is 73C enough to fry a rx 470 8gb?

5. I feel like this has something to do with the Memory Clock, is 1850 alot if stock is 1750?

6. (random oc question) If my GPU usage keeps going down to 0 sometimes during a stress test mean that it's not stable? The stress test I ran often goes black and fps changes from 20-100 with an average of 40ish fps.


When reinstalling GPU drivers I ended up with no drivers (i think). I tried starting a game and it did not work. During this time I saw no artifacts on my screen if that is off any help to someone trying to figure out what is wrong with my pc.

  1. Did you try OCing using drivers and AMD Radeon settings rather than Afterburner ? I found Afterburner very flaky.

    No I've only tried using MSI Afterburner. I uninstalled the program earlier today though and the problem is still here.
    When I got this all sorted out I will attempt to overclock again and will probably use a different program.

  3. Did you set Afterburner to defaults before uninstalling it ? Otherwise it will keep whatever settings you left on and keep on making problems even after uninstall because it changes settings in the drivers.

    I use Global Wattman built into the radeon drivers themselves, I only apply a very small overclock to the core though, not like my CPU, I dont push the limits.

    I actually went all the way up to 1400 (Stock is 1220) Core Clock but after 30 min of stresstesting it reached 73 degrees C which is a bit to much for me. And I would probably have to add even more voltages to keep it stable (if it's even possible).
