The default clock is 775mhz and the memory is 1000mhz when overclocked I can get 875/1175mhz, I have just found out that earlier versions of this card the voltage could be adjusted to 1.2v, this one is locked, can't be changed, I think it is 0.95v though Trixx says 1.175v! GPU-Z reports .95v though no monitoring shows.
Rather disappointing since my decision to purchase this is on the recommendations of a review, that now seems to be an earlier version!
It is better to buy the non OC version!
