Noise, Overclocking, 2D Quality

The cooling system of this graphics card is completely silent in the passive mode. If the additional fan is installed, there is some noise, of course, but the fan is not too loud, at least no louder than the other system components. And you also have an opportunity to replace it with another 60mm fan with better acoustic characteristics. So, the PowerColor Bravo X700 is blameless as concerns noise.

In our overclocking experiments, however, the card simply failed. We met visual artifacts in 3DMark03 and Unreal Tournament 2004 as soon as we increased the memory frequency to 300 (600DDR) MHz. The artifacts didn’t vanish even at the default frequency of 266 (533DDR) MHz, and we only got rid of them by setting the memory frequency at 250 (500DDR) MHz. So, we kind of got a card with negative overclockability for the first time in our tests. The memory chips couldn’t overheat because we set an additional 120mm fan to blow at the card, so we must have had a defective sample. The graphics processor could overclock to 420MHz; some visual artifacts appeared at 430MHz and at 440MHz the card would hang up in 3DMark03. So, we have to confess that our sample of the PowerColor Bravo X700 was no good for overclocking at all.

The image quality in 2D applications this card provides is quite high. The image remained sharp, without blurring or shadows, on our Dell P1100 monitor even in 1600x1200@85Hz and 1800x1440@75Hz display modes.
