Overclockers have broken the 1000MHz! mark with the X1800XT, The overclockers have managed to overclock the VPU's core speed to just over 1000MHz this is a first for VPU's worldwie.

This is a good new for X1800XT owners: in fact, may be these vpus are underclocked by default so people can easily increase the clock of these without stability problems (in agreement to the "real" specifications). The main question is now: what is the on board memory response when the overclocker changes its clock to get the card best performance? Is ram too much slow to follow the higher core clock?

However, in the nexth future some ATI partners will be launch special version of X1800XT, just named X1800XT OC...
