White display flickering

[xTheLaw]

After installing my new GPU, Sapphire R9 270 oc, i'm getting weird traces on my screen while playing games. It only appears while playing games. It also appears on the desktop while a game is running in the background. I can't capture it on a screenshot for some reason (it looks normal on it) but here is what it approximately looks like http://prntscr.com/6diyh8 (the white bars flicker all over the screen. In reality they are only slightly vissible but it's still very distracting) The issue never appeared with my old GPU - Radeon HD 4670

Edit: The issue dissapears when my FPS is locked in sync with the refresh rate (60, 120, 240...)

Things i tried:
-Reinstalled Windows
-Updated and downgraded my driver
-Changed the DVI to VGA adapter
-Connecting my laptop to the monitor, no issues appeared

My specs:
CPU - Athlon II x3 455 3.30 GHz
GPU - Sapphire R9 270 Dual-X OC
Mobo - AsRock N68C-S UCC
RAM - 4GB Transcend DDR3 1600 MHz
PSU - Thermaltake Smart SE 630W Monitor - Asus VH228D

Does your monitor support HDMI or DP? If you can, try and use a direct cable from the GPU and run it to the monitor. There's nothing wrong with VGA but it might be the port on your card. If using a different cable and port doesn't work, send the graphics card back for RMA.

My monitor only supports VGA so i can't try the other connectors. I tried using a spare VGA cable but the issue still remains.
I would like to keep RMA as my last option so any other ideas would be appreciated.

Damn, that's weird. VGA only monitors are really old.

While it seems like a graphics card problem it might be the monitor. What refresh rate is it set at right now?

Woody

It's set to 60 Hz, it seems like it only happenes while the GPU is under load

 

[Woody1999]

Okay, looks like a card problem. What clock speed and memory speed are you currently running at?

Woody

Running at stock clocks:

-Core clock: 945 MHz
-Memory clock: 1400 MHz

Try changing the clocks, up a bit or down a bit. Sounds weird but I've fixed some visual issues by overclocking my 260X.

Woody

Increasing/decreasing the clocks on my GPU didn't help

Very, very weird. It looks like RMA may be your only option.

Bear in mind that your processor will bottleneck the 270 quite a lot, my Q8300 which is slightly better than the Athlon II X3 bottlenecks my 260X loads.

I'm aware of the bottleneck, I will get a i3 4160 or i5 4460 when I'll have more money. Thanks for the effort anyway.

Off topic slightly, but do you play CS:GO?

Woody

Yes and for some reason the issue is most appearent on CS:GO

 

[Woody1999]

Hm, do you know a person called Kou? He changes his name often, but it's always Kou somewhere.

Woody

No i don't and let's not go off topic any more.

 

[Woody1999]

Fair enough, sorry, he just knows a CS:GO player called TheLaw. Well, I've helped you as much as I know. You'll either have to find a person who knows a lot more about video cards than me, or just RMA it and get a new one.
