stress testing software for nvidia graphic cards? Atitools?

post #1 of 6
Thread Starter 
Hello, i'm wondering about which program to use to stress test my nvidia graphiccard (GTX750Ti), i haven't overclocked a gfx card in ages and so i'm kinda out of the loop on which program to use to stress test it.
I'm using msi afterburner as the oc utility and TechPowerUp GPU-Z for monitoring. I just recently got a Palit GeForce GTX 750 Ti StormX Dual 2GB and atm i'm just using Total war: Rome 2 benchmark as stress testing, i haven't noticed any artifacts but which program do you guys recommend? I used to use the stress test in atitool when i had my old Leadtek 7800GT biggrin.gif.

On nvidias webpage: "Thermal and Power Specs:
95 CMaximum GPU Tempurature (in C)" Would that be the maximum safe operating temperature?
Lets say i ran constantly at 95C, would that seriously harm it? redface.gif. I'm just wondering, my gpu has only hit about 70C maximum, atm i'm running it at GPU Clock: 1239MHz, Memory: 1521MHz, but here's another question, my boost goes higher on the sensors in gpu-z and other monitoring programs, then what gpu-z claims is the boost speed on the graphiccards tab.
For example, my boost according to the gpu-z tab
Gpu boost: 1318, sensors actual reading: 1370MHz
btw, stupid noob question, it only boosts the core right? Not the memory. rolleyes.gif

Yes it only boosts the core.

No I wouldn't want to run at 95 degrees constantly. 85 is about the limit but of course the fan will ramp up long before you get into the 90's

As for stress testing, use unigine heaven, 3d mark 11, 3d mark fire strike.

Msi kombustor will let you know what your maximum worst case temperature under full load will be. Use this program sparingly as it has been known to cause gpu's to throttle or fail.

Heaven is the easiest as you can just run it and let it loop.

Thank you for the answer, altough i actually had windows xp sp3 (32bit) so i couldn't use the 3dmark 11, but i found out you can get vista legally if you got a product key, which i have.. it's from another computer that i took parts from, so i downloaded and installed it and got 64bit vista. It's still no windows 7 but it was free, and now i've upgraded to 8gb ram biggrin.gif, so i'm super excited, even though it's only 1080p on a 27" benq screen, i still manage to multitask alot thumb.gif. Thank you for the help and you answered all of my questions and you've been repped (reped?) redface.gif
Ooh, and for those wondering, i got my 750gtx ti core up to 1401mhz and it's stable. No extra voltage or anything.

That's a very healthy overclock on that 750 TI. Should work well at 1080p with most details maxed.

Glad you're enjoying your machine.

Been a pleasure to help

Thank you, yeah, i'm very happy with my pc atm biggrin.gif. I'm getting great results on my games, since i went from the 7800gt it's like i've experienced a new world of "awesomeness" happysmiley.gif I'm sorry if it's wrong to reply, i'm very poor when it comes to forum etiquette, you don't want a conversation to sometimes go on forever, it might irritate people redface.gif. But anyway, thanks for the help and do you think i should increase my voltage as long as the temp is safe? That wouldn't hurt it right? As long as the temp is safe.

It depends on how much voltage you wish to add. Sometimes even though the temps are safe the voltage actually is too high for the clock you're running and accelerates electron migration.

A classic example...

Some gpu's get fussy with certain clockspeeds. At certain voltages within those clockspeeds chip leakage starts to cause issues with heat which them directly affects stability and longevity.

To simplify...

Increase voltage as long as that voltage increase doesn't result in dramatically increased temps (you've reached major chip leakage point) and only bother to increase the voltage enough to make the clockspeed you're running stable.

The 750 TI is running a brand new architecture that we don't fully understand yet as the "full" maxwell gpu has yet to be released. But from what we know already it's very power efficient and won't need a whole lot of voltage to clock pretty high (as you have discovered)

Also, never be afraid to ask questions. I can say with some certainly that most of the people on the forum like helping out (I'm one of those) and we are all here to learn.

Welcome to awesomeness.
