ATi umožňuje některým výrobcům taktovat X1800XT na 700 / (800)1600MHz

Currently, the standard clock settings for the Radeon X1800 XT are 625MHz for core and 750MHz (1500MHz data rate) for memory. Because ATI is experiencing good yields on the Radeon X1800 XT core, it is allowing boards to be overclocked to 700MHz core and 800MHz memory (1600MHz data rate). In the document, ATI also indicates that standard clock settings are often set at conservative speeds to produce the highest output yield possible.
