Sapphire X1600 XT - Web Support
Sapphire's website can be found at www.sapphiretech.com. The support section links directly to ATI's Customer Care section, so it is easiest to get the reference drivers straight from ATI's download section at www.ati.com.
Sapphire X1600 XT - Overclocking And Heat
Since the Overdrive section of the driver is unavailable, overclocking through the driver is not an option. The default clock speeds are given as 581/684 MHz (GPU/memory) in the driver's Information Center. For reference, the competition clocks its cards at 587/693 MHz, but this discrepancy makes only a minuscule difference in overall performance. The card does not feature a temperature sensor. The memory frequency you see in the screenshot is the actual clockspeed; since this is DDR memory, the numbers quoted in the technical specifications are twice as high.
