Sapphire Radeon X1600 Pro AGP - Web Support
Sapphire's website can be found at www.sapphiretech.com. The support section links directly to ATI's Customer-Care section, so in effect the best and quickest thing to do is to get the reference drivers straight from ATI's download section at www.ati.com.

Since the Overdrive section of the driver is unavailable, overclocking through the driver is not an option. A temperature indicator is also absent. The memory frequency you see in the screenshot is the actual clock speed. Since this is DDR memory, the numbers quoted in the technical specifications are twice as high.
