ASUS EAX1900XTX - Radeon X1900XTX From Asus
Overclocking
As we neared the end of our testing, we spent a little time overclocking the ASUS EAX1900XTX using the clock frequency slider available within ATI's Catalyst driver suite, under the Overdrive tab. To find the card's peak core and memory frequencies, we slowly raised their respective sliders until we began to see visual artifacts on-screen while running a game or benchmark, or the test system became unstable.

After tempting fate and pushing the card as far as we could while retaining complete stability, we were left with an impressive 53MHz increase in core GPU frequency and a 120MHz boost in memory frequency. We were slightly surprised to see the memory frequency fail to hit higher speeds as the modules are rated for up to 1.8GHz. Regardless, free performance is hard to complain about and the plot above illustrates the healthy jump in score we witnessed in 3DMark06.

Fortunately, our overclocking efforts had a similar effect on F.E.A.R. At a resolution of 1600x1200 with 4X anti-aliasing and 16X Anisotropic Filtering enabled, the ASUS EAX1900XTX jumps an appreciable 3fps and tops out at 54fps. As many gamers look at 60fps as the holy grail of acceptable framerate for fluid gameplay, every step in that direction counts.
