nvidia shader stress programs

[KainXS]

are their any programs that will stress an Nvidia GPU 8 series + shaders to its max and be able to bench them, I tried furmark and the only thing I see is that furmark does not even care how many shaders an nvidia card has, I set the shaders on my GTX to 2500 and it gets the same score as it is at 2000, any one know a good benching program for shaders.

Furmark in stability mode for 300 to 600 seconds with AA. That gets my GPU hotter than any game, benchmark or any other gpu stress test out there. If you're after stress and score, then run vantage loops.

Furmark.
You just need to learn to properly OC your video card.

no, furmark does not care what an nvidia cards shaders are set to, I need a program that will accurately test the shaders, ie the tmu's

the only thing I can find is perlin noise loops on 3dmark 06

software is not, should not and can not be concerned with the number of shaders in a gpu. that's why it's such a nice design. just run your shader code and it will magically run multiple times

can you explain what you are trying to test?

Im trying to test if the shaders on my card are bad, when I run intense shading games ie crysis, it gets artifacts, or perlin noise loops, i get artifacts, on furmark I get nothing and other games.

its not like you have little hamsters in your gpu and one of them suddenly died.

can you specify "artifacts" a bit more? screenshot ?

in that order: clock down core, memory (each one on its own, below stock), remove all cpu overclocks, try the card in another pc, send it in for rma.

you can not target specific shading units on a gpu

edit: could it be a heat problem? artifacts show up after a certain time, never on a cold pc

furmark does not care what an nvidia cards shaders are set to

Except for the fact that Furmark is heavily dependant on GPU's shader performance, and the points/FPS scales hand-to-hand with shader performance.

I set the shaders on my GTX to 2500 and it gets the same score as it is at 2000

Obviously, the shaders in your card never ran >2GHz if you didn't gain higher score.
See it for yourself by peeking in Rivatuner Hardware Monitor. Thus...

ATITool's stress program will reveal if you have an unstable shader overclock. I know this firsthand while finding my max shader OC for folding at home with both of my 8800GT's and 8800GS's.

Edit: Unless you have performed a hard volt mod on that 8 series nvidia card, you will not get 2500 out of your shaders, period. My BFG 8800GT needs about 1.3V vGPU for me to get 2000 on the shaders, and that's with modified cooling that's about on par with water. Rivatuner will allow you to set the clocks higher that what's stable, but it won't be stable with anything stressful.

Yeah, I was looking at the memory clock, the cards shader clock is 1900, but I bought it on ebay last month, and it worked for 2 days and I just tried to run another benchmark and it rebooted as soon as it started, now the pc won't stop rebooting unless i take it out, is this card cooked,

this card drivin me crazy
