As it was reported earlier the G70 core has two frequencies - the ROPs frequency is higher than core`s for 30 MHz. But how will it scale during OCing ? Guys from Hardware.fr have made some investigation. And this is what they got :



The first column shows the core speed as you can see it in any hardware utility like RivaTuner. the second is the Pixel pipelines frequency. And the third - vertex processor units frequency. As you see the numbers differs. This leads to some sort of usefull OCing steps which can be ilustrated by this graph (for GTX version)



Unlocking the missing quad of pipelines is another story. Overclockers.ru reports that HKEPC (and IMO other lucky guys) could unlock their`s GTs cos it was engeneering samples, which won`t come to market. So only the actual owners of 7800GT will proove (or dispel) this.
