Your thoughts on GPU stress testing software? Also I need help with an occasional issue with severe fps drops in games...

I've been looking about to see what's the best stress testing software for graphics cards. From what i've read it seems like OCCT is a good one because it's the only one that I'm aware of which can detect errors rather than you having to stare at the screen for ages looking for artifacts. There seems to be a bit of controversy about this kind of software though - some people seem to think it just causes damage to your graphics card.

Just wondering what you guys think of this kind of software, what you personally use, and with which settings?

I've been having this issue in games where I sometimes get stuttering and massive slow-downs/frame rate drops for about 20-30 seconds, and then it all goes back to normal. It doesn't always happen, I can be playing a game for hours without this problem. But sometimes I'll play a game for 2-3 hours and this will happen twice in that sort of time frame. I'll give a few examples...

*The one I've noticed the most is sometimes with Battefield 3 erverything will be jerking around and stuttering which kind of feels like a bad framerate, except the framerate is actually good, the game just stutters. Sometimes restarting the computer is the only way to fix this. I noticed it happen a little with the 11.11c amd drivers, much worse with the 12.1 preview drivers, and now a little again with the 12.1 final drivers. I thought this might just be a driver issue but am suspicious it could be caused by my overclock.

*Lastnight I was playing portal 2 for about 2 hours and it happened once.

*Today I played Need for speed Shift 2 and it happened twice within the space of a few hours. The game slowed down so much that it actually froze for a couple of seconds, then the framerate slowly built back up until it was back at 50+ fps like normal, and stayed there until I finished playing a while after.

I have MSI Afterburner running and I can see my VRAM hasn't maxed out at any point yet so it can't be that which has caused it...


What do you guys make of this?

Thanks!

OCCT is good but most people still use furmark and MSI afterburner kompter or something named like that.

Artifacts are important to watch for. However when i overclock if my clocks are unstable i have a graphic driver crash, or a lock up in general.

I personally use furmark and the msi kompter. I stress for a few hours and wait to see if i get a driver crash. Then i play games, if i see artifacts i up the voltage, or downclock a bit.

Any stress test can be detrimental to your video card. However Furmark and OCCT are known to run hotter than others. So you really need to watch your temps, however i say use them anyways because if your clocks are stable in OCCT or Furmark, your pretty much guarantee you wont have any crashes during games, because these two programs stress test your GFX card to the max.

With FPS dipping, i never really encounter this problem but i don't game much these days. try a older driver, Such as 11.8. If you still see the problem bump up the voltage a bit, or downclock a bit. It should clear right up. Stuttering can be unstable clocks, you may not getting any errors during stress test but during games you might its weird like that.

MSI Kombuster is basically furmark though isn't it?

I've had BF3 quiting on me at points complaining about some incorrect Directx command or something like that. Not the same as display driver crashes that i've seen before but i guess it might point to the same kind of problem?

I never got why people were saying these progs are bad for your graphics card when the same people probably use something like Prime95, LinX, Intel Burn Test to check their CPU's. Sure the life of your components is gonna be shortened if you keep running these progs but using them to check overclocks on occasions is necessary right? I'm just not sure if theirs more to it with these GPU stress testing tools because I've never seen much people saying these CPU stress testing progs are bad to use... Why the GPU stress testing tools?? I make sure I keep my temps under control - with games I occasionaly go to about 70c, maybe a few over and i'll make sure the temps are around the same when stress testing so that's not an issue here smile.gif

I know what you mean though with passing stress tests but getting errors in games when it comes to graphics cards. These days I just use demanding games as my stress test for the graphics card. If I can play for a few hours on a demanding game without any issues then I feel pretty sure the overclock is good.

As I am still suspicious about the overclock I thought I would up the volts slightly in afterburner but it won't let me unlock voltage control. I could go back to using Sapphire Trixx but really don't want to... I'm just gonna try lowering the clocks a little at a time and then game for 2 or 3 days and see if this issue stops. I'll get the 12.2 drivers soon to and see if that changes anything.

Thanks for the good response thumb.gif

Still I would like to know what others think of GPU stress testing software??
