Not content with the performance of the Ti4600 Gainward decided to add that little bit of performance to their cards; like some other cards in their range they set the card's default clock speeds past the default 300MHz core, 650MHz memory to 310MHz core and 680MHz memory. So they are selling overclocked products? It seems not. Gainward receive special batches of NVIDIA chips, any that fail to hit the mark at 310MHz get sent back.
