Ohh btw i also have a few ram heat sinks on the back of the card i read in a forum this dude did a test of heat output there was some spots that heated up a lot so stuck sum there so far its pretty stable im gonna kick it up some more?


What do you guys use to test the stability of yer card i mean with a cpu yu got Prime 95

I have Ati tool and gpu viewer is there like a set time it should stay under before i know its stable i always use games to test it like Crysis or command and conquer Kanes wrath.

ATI Tool is pretty good for stressing the card. Games are a great real world test. And of course the suite of 3DMark benchmarks. After you have done the rounds with the stuff you like to use, I would try 3DMark 03 on your GT. IIRC there is something in that test that will cause an avalanche cascade on a seemingly, otherwise, stable overclock, especially if the test is looped. This is something reported by ViperJohn and sure enough I found it to be very true. You can search OCForums as that's where I first read about it.

I've found Crysis to be the best test of an overclock, bar none. It gets the gpu hotter than atitool as well. the opengl fur benchmark will make your card ridiculously hot, hotter than both crysis and atitool but I've had my card survive the fur benchmark but still fail crysis.

Did some tests with ATI tool on 700MHZ-CORE 2000MHZ- MEMORY 1700MHZ- SHADER

CLOSE TO 3 MINS IN


Stable at 51 degrees next up 10 mins !


Still 51 Degrees tested this with Crysis too gonna take it up a notch.

Conclusion- VF-900 is still king!

That's incredible, I don't understand why my card runs so much hotter! Could it be that the heatpipes are defective? Also, be careful about setting clock speeds as atitool and gpu-z don't tell you the true clocks. The frequency of the shader/core/memory do not increase linearly, they increase almost exponentially because of the internal multiplier on th card. For example, as you have set 1700 on the shaders, it is actually running at 1674, there is no bypassing this. I'm currently sitting at 64 degrees celcius using your overclock ( but 1674 on shader) with a room temp of 22. Damn, lol! I'll be getting an Accelero soon, though.

Wow 64 degrees? That is at load right?

I have the akimbo cooler on one of mine and with the fan set at 30% I'm sitting at 41C and that is with the card at 734 Core 1836 Shader and 1000 Memory. At full load I'm hovering right about the 50-53C mark and that is with the fan at 50%. And at 50% it is still very quiet, not completely silent, but almost.
