Screen Spazz!!

snips86x · 11 Oct 2013 at 18:41

If my screen starts spazzing out, and by spazzing i mean you get black and gray line flashing in a horizontal manner rapidly, when browsing the internet, which of the settings below should I look to reduce?

The overclock seem to be fine in games, just been playing BF3 with no issues, spec is:

2500k @4.5 (1.33v with a +0.030 offset)
Asrock Extreme 7 Gen 3
16gb Patriot RAM @ 1600 (I think)
24" BenQ & 22" Samsung (secondary)
MSI HD 7970 TF III @ 1145/1425

Try not using precision x for a start, its tailored for nvidia cards

It's been working fine for the past few months, which makes me think it's an overclock thing.

Are the lines across your full screen or just within the window i.e if you drag the window around do they go with it?

Full screen on the primary monitor. They were only visible for a little while and I was using the 2nd fine when it happened.

my pc crashed out on BF4 beta and i ended up with exactly what your describing, had to remove drivers and reinstall then all was good.

Can I request some clarity?

When overclocking your graphics card, what should you lower when you get game crashes & artefacts?

Am I correct in thinking that artefacts are linked to the memory and game crash the core?

LtMatt · 19 Oct 2013 at 20:08

Describe the artifacts? They can be caused by a combination of the core getting too hot, the core being clocked too far or the memory being clocked too far. Generally core artifacts are sparkly. Game crashes could be either. Gpu driver reset crashes indicate core. If the pc freezes up, or you get stripey coloured lines down the screen, memory.

Flashing triangles over the screen and all the other symptoms would indicate I was correct in my thinking, even if it wasn't described well.

Got a screenshot? Triangles could be memory. Failing that try lowering one then the other till it goes away.

No screenshot! It started to bug me so I reverted back to stock speeds. I can only describe it as the tessellation was visible like it was out of sync.

If it keeps doing it then just overclock one at the time and you will find which one is the culprit.

By black and grey lines are you referring to the renowned grey screen of death? if so then it's probably core.

snips86x · 21 Oct 2013 at 18:52

Ok, so I've been using the below settings for about 2 days now and suddenly, while browsing the net, it's done the gray screen again.

My primary monitor is a 24" BenQ 1080p (DVI) and secondary is a 22" Samsumg (DVI), PSU is a HX850 Pro.

Is my card just not cut out for overclocking? My old 660 TwinFrozr was just as bad at overclocking. Have I got unlucky?

Also, if I keep having this issue, can I damage the card?

LtMatt · 21 Oct 2013 at 18:55

Firefox? Try a different browser. Then try disabling hardware acceleration. Then report back.

Suarez7 · 21 Oct 2013 at 18:59

My 7970 would only grey screen when the memory was overclocked. Does it happen on flash based webpages?

Chrome!

I've disabled hardware acceleration for all the browsers used (3) and will see how it goes. The mind boggles sometimes.

I was on OCUK.

jakspyder · 21 Oct 2013 at 19:22

Thats probably some code OcUK put in to cause artifacts, tempting you to get an 290X

snips86x · 22 Oct 2013 at 19:47

Same issue again, Firefox was open on 1100/1400. Dropped to 1090/1400 to see how it goes.

Will it damage the card?

You could try setting a custom 2d profile with clocks as low as possible in afterburner using the profiles section. Assuming you don't have a faulty card in confident it will solve your issue.

I give up! Cannot be *****ed with this card anymore, sod overclocking. It's testing my patience.
