Even though the Crucial Radeon 9700 Pro is an extremely
powerful videocard in its stock configuration, we at PCstats.com
are obviously interested on how much higher we can push
this little red videocard. We like speed, and the more we can
get, the better!
I first tried overclocking the core,
moving up a few MHz at a time; 350 MHz, then 360 MHz and no problems
at all. At 376 MHz the artifact tester started to register artifacts, so I lowered
the core speed down a little. Even though the artifact tester registered artifacts,
they weren't visible to the naked eye until about 383 MHz core speed.
In the end I
settled for a 375 MHz core speed which was a bit more useable.
As we mentioned earlier, the Crucial Radeon 9700 Pro uses 2.8ns Samsung
BGA DRAM, so I was expecting at least 714 MHz out of it (1000 MHz / 2.8ns x
2 = 714 MHz). For a more detailed explanation on how this formula works please
read this article here.
I upped the memory slowly from 620 MHz to 650 MHz, then
up some more to 675 MHz and still no problems, but we hit the wall
at 684 MHz. Like with the core, anything higher and
the artifact tester would register artifacts. This was a little disappointing considering 2.8ns
memory should do 714 MHz. Perhaps the memory is being held back by
lower voltages rather then bad memory, after all it's well known that Radeon
8500LE cores and memory get less voltage then their non-LE counterparts.

* - We will be benchmarking with two sets of Detonator
drivers because the new Detonator 40's bring a big performance boost to DirectX
8 benchmarks. Please remember though the Detonator 40's are beta!
3DMark2001SE is the latest installment in the 3DMark series
by MadOnion. By combining DirectX8 support with completely new graphics, it
continues to provide good overall system benchmarks. 3DMark2001SE has been
created in cooperation with the major 3D accelerator and processor manufacturers
to provide a reliable set of diagnostic tools. The suite demonstrates 3D gaming
performance by using real-world gaming technology to test a system's true
performance abilities. Tests include: DirectX8 Vertex Shaders, Pixel Shaders and
Point Sprites, DOT3 and Environment Mapped Bump Mapping, support for Full Scene
Anti-aliasing and Texture Compression and two game tests using Ipion real-time
numbers denote better performance.
It was well
known that the GeForce4 Ti4600 was CPU limited at 1024x768, with the Radeon 9700
Pro, this is even more apparent!
