Whats a good gpu stress tester?

Kevfactor · May 14, 2013

hey ya i currently have used prim95 for an hour and no problems

a 3770 oced to about 4.4 Using the CPU graphics hd4000 my pc however occasionally will do a flicker. i think it could be the monitor or the hdmi cable (might switch to dvi later).

just would like to runa gpu stress test to see if that's going to cause blue screens because i plan on gaming and editing pretyt har don this pc once i stip out my 670 ftw from this current one hehe.

Try Furmark

yep, furmark for sure

Try Unigine Heaven benchmark and furmark w/Precision X. That's what I used to OC my 670 ftw.

How long would you guys recommend to stress test your GPU to safely assume your OC is stable?

I thought the drivers detected Furmark now and slowed down. Running Heaven for an extended period of time would certainly stress a graphics card. Since it's a nVidia card, you could also fold with it for a while.

Furmark for heat testing - not the best at stability testing. I've OCed GPUs to the skies and Furmark let them slide, but they'd crash immediately upon entering a game.

Unigine Heaven 4.0 is the most picky I've found when it comes to testing, and will crash out even when an OC looks stable, even in gaming. Test Unigine under both DirectX11 and DirectX9, as I've recently discovered a certain brand of GPU will crash when overclocked depending on which you choose. Best to run both.

*Edit*
I'd run Furmark's built-in Burn In test (I think it's 15 minutes) to check your cooling capabilities, and I'd run Heaven's benchmark three times in a row, keeping an eye on the numbers it returns. If you're happy with your OC and the numbers, let it run a while, at least a few hours, overnight if you can spare it, just to confirm stability.

CooLWoLF :

different people have different definitions of "stable"

functionally stable, i'd run it for an hour

truly stable, id do much longer, like a day. However if you're overclocking, there's always that random crash you may get one day down the road now matter how much you stress test, so it's up to you

I use OCCT cause it does everything with one utility:

1. Loads GPUs
2. Loads CPUs
3. Loads PSUs
4. Monitors temps
5. Monitors voltages
6. Graphs results

I do 15-20 minutes or till I get a crash, then back down a notch and go for an hour
