best app for stres-testing the video card?

[Daniel Czajko]

I wanted to find out how far I can OC my Radeon 9700 pro. So I would keep
incrementally increasing the core/memory MHz followed by running 3DMark2003.
I'd keep increasing the speed until I'd see video artifacts. Then I'd step
the OC down a bit and assume that this was as far as I could OC the card and
still have it run stable. But that wasn't the case. Some games did run
stable at the OC'd speeds, and some showed nasty video artifacts few seconds
into the game. So why didn't those artifacts show in 3DMark? Does 3DMark
not tax the VideoCard completely/accurately?

Since 3DMark wasn't a good way of determining how far this card can be
pushed, I'm trying to find some program that can stress-test a 9700 pro to
tell me the real OC limits.

Is there anything out there that you guys can recommend?

thanks

I'd give AquaMark a try. Belive me it puts stress on your card. JLC

Don't trust ATI tool too much-- I was using it the other day and my 9700 PRO
just went dead while it was overclocking. It isn't as smart as some people
on here think. Overclocking is RISKY and really not worth it. If you mod
your board, you have very little recourse. If your board is all stock, you
are at the mercy of the manufacturers replacement policy when it breaks--and
it WILL break it is just a question of when.

Play it safe.
