New Gigabyte GTX 960 causing flickering edge of screen

brad1990 · Feb 29, 2016

Hi everyone. I recently installed a new Gigabyte GTX 960 4GB OC (GV-N960OC-4GD), I started noticing some odd flickering at the top edge of my screen whilst playing games on Steam and GOG Galaxy.

Flashing white dots appear at the top left and right corners and also centre of top of the screen. It usually occurs within 20 minutes of playing for a few minutes, then stop and start again periodically.

This hasn't happened with any other GPU I've had, and my monitor is fairly new. I have tried reseating the GPU, and reinstalled drivers etc.

Here are example videos I took: http://

Pretty annoying! Any suggestions?

try to underclock it and tell us if the flickering is gone

Yeah,try to underclock by lowering your clock speed and memory clock and test the game.

Th3R3ALaSSaSSin4 :

Ok, by how many MHz should I underclock them? Or does it not matter? Not done this before.

stavrosmast · Feb 29, 2016

As much as possible

Th3R3ALaSSaSSin4 · Feb 29, 2016

Try to underclock slowly and try until you find a stable Clock

brad1990 · Feb 29, 2016

I will try it, using MSI Afterburner, hopefully doing it right...

Th3R3ALaSSaSSin4 :

I've tried a few different underclock settings, not noticed much difference.

Also noticed the flickering doesn't occur when running games that don't tax the GPU much.

try other port,cable,monitor,pc

stavrosmast :

Ok, I tried a different cable, same results. Unfortunately I don't have the equipment to try other monitors/ports.

But I did connect to my TV, and there was no flickering. It's a 32" full HD TV.

If that's so,try different screen and game resolutions then tell me what happends

brad1990 · Mar 6, 2016

Th3R3ALaSSaSSin4 :

I tried lowering the game resolutions, and the flickering doesn't occur at resolutions below 1080p.

Th3R3ALaSSaSSin4 · Mar 7, 2016

How about Desktop resolutions?

brad1990 · Mar 7, 2016

Th3R3ALaSSaSSin4 :

Well the flickering doesn't occur on the desktop (except sometimes for few seconds after quitting a game as it was occurring) and I did try to change the desktop res but the game overrides it?

Th3R3ALaSSaSSin4 · Mar 7, 2016

I think that the monitors refresh rate.Is VSync enabled on the games you play?

brad1990 · Mar 7, 2016

Th3R3ALaSSaSSin4 :

I've been playing Fallout 4 which has vsync forced enabled. I can try disabling it?

stavrosmast · Mar 7, 2016

Yes you could

I would RMA the gpu or update the Bios

stavrosmast · Mar 7, 2016

and ofcourse try it on another pc etc

brad1990 · Mar 7, 2016

stavrosmast :

I'll try the vsync. I already updated the bios to fix a fan problem,didn't affect the flickering.

What's RMA?

Th3R3ALaSSaSSin4 · Mar 7, 2016

First try your GPU on another PC and try another moniotr.RMA is to return a product to the manufracturer if it has defects and to get another fixed one.

brad1990 · Mar 8, 2016

Thanks for all your suggestions, but I've decided to just return the card as it's too much hassle to do any more testing.

brad1990 · Mar 10, 2016

Ok, I got a new gpu (an ASUS gtx 960 this time) and the same thing is happening...so I guess it's not the card causing it?

Could it possibly be the psu? It is the minimum 400 watts required by the card, but I have been using it for a few years now.

stavrosmast · Mar 10, 2016

If it is low quality yes

Did you try it on another screen/pc/port?

brad1990 · Mar 10, 2016

stavrosmast :

It's a Silverstone Strider psu, seems good quality...

I don't have any other screens to test on at the moment.

stavrosmast · Mar 10, 2016

There is a good possibility that it might be your screen

Try it to another one if you ever can
