I have a Leadtek GTX extreme in my system which is clocked at 490Mhz from the factory. When I ran 3dmark05 I managed to get 8302 (X2 3800, 2gb Gskill, A8n-sli) without any overclocking, but the report said that my GPU was clocked at 529mhz. Im running the latest offical drivers with no Leadtek software installed. Is this an error or did the card auto clock itself??
