Noise, Overclocking, 2D Quality

The cooling system Leadtek put on the WinFast PX6600 GT TDH didn’t prove to be absolutely silent, yet its noise mostly consisted of the rustle of the air rather than of the much more noticeable and annoying buzz of the fan. We observed no overheat-related problems, so this cooler from Leadtek should be considered a good solution.

We were very pleased with the overclocking potential of the WinFast PX6600 GT TDH: we managed to lift the core frequency to 650MHz, i.e. 150MHz above the default clock rate! For this overclocking test we installed an additional 120mm fan to blow at the card and tested it in an open testbed. We don’t recommend to you to repeat this experiment without improving the standard cooling of the card. The memory, unfortunately, couldn’t work at frequencies above 1020MHz – there would appear various artifacts on the screen. We could have probably got a score of megahertz more if we had installed additional heatsinks on the memory chips, but 1000MHz default clock rate is already high.

No problems with the 2D image quality – the card’s both outputs, D-Sub and DVI (via an adapter), yielded a perfect picture in all resolutions up to 1800x1440@75Hz inclusive. This item checked up, we can proceed to our tests.
