Noise, Overclocking and 2D Quality
ATI Radeon X1900 XT/XTX graphics cards are equipped with the same cooling system as installed on the ATI Radeon X1800 XT, so their acoustic characteristics are identical. The fan works at its full speed only at the start of the system and then steps down to the min speed and becomes almost completely silent. The fan speed may occasionally increase in 3D mode, but the noise remains in a comfortable range even then, although there is a rather irritating “plastic” tone in the noise due to resonance in the cooler’s sealed casing. The fan seems to be ready to speed up even more if the GPU die temperature becomes still higher, but it didn’t do so even once during our tests. The card was quiet on our open testbed, so it is going to be perfectly silent in a closed PC system case.
We couldn’t check the overclockability of our sample of the card, although ATI Technologies had given us the latest version of the WinClk utility. The program just did not recognize the installed RADEON X1900, while the rest of overclocking tools do not support the new series of graphics cards from ATI as yet.
Both the ordinary version of Radeon X1900 XT/XTX and the Radeon X1900 XT CrossFire Edition yielded an impeccably-looking 2D picture in all resolutions supported by our test monitor, including its highest 1800x1440@75Hz mode.
