Nvidia partners overclock 6600GT
 

MOST, IF NOT all Nvidia partners intend to introduce overclocked versions of the Geforce 6600 GT card.
Nvidia sent out Geforce 6600 GT to the press with card that featured a 500MHz GPU clock and 1000MHz memory clocked card. Its partners suddenly received the green light from the green company that they can use 1100MHz memory and that will obviously increase performance numbers.
