Graphics glitch help

[steven_belfast]

Greetings folks

Could some of you kind techies help with this one.
I have strange and random flickering on screen see video

Fire strike - when one of throwing the other you really see it.

Temps are all ok, core and vrm
Not overclocked also I underclocked for testing

I have tested 16.7.3 / 16.8.3
I upgraded via amd software and also did clean install , removal , wipe and reinstall
Reseated card and also checked ram.

I am also not able to play battlefield 3 / 1 without it crashing.

You've covered all of the things I would initially suggest. Based on what you've tested, I'd say the vram is bad. Is it still under warranty?

Try dropping your memory a couple of hundered Mhz and run again. It might help show if it is memory failing but might not either but it does look like memory to me.

I hope so
Think I am going to try older drivers 16.7.1/2
Seems others having issues from 7.3 and higher.

Already dropped vram down from 1250 to 950 and core from 1050 to 800
Also dropped system ram down and tested 1 stick at a time issue remains.

Hoping this to be software only but will check tomorrow had enough for tonight.

 

[steven_belfast]

Well it's not driver ,
Tested 16.7.1 & .2 & .3 also 18.8.3 ( think that's right )
Reinstalled windows Oh the joys

I heavily under clocked both core and memory on gpu, also dropped ram to 1333 all ok so far in 3D mark,

Very slowly going to up each clock and see when it crashes.

 

[steven_belfast]

Well no crashes after slowly upping the gpu clocks,
Still getting artefacts once core clock is set to factory but no crashes.

Will look at the ram next.
