R7770 Black Super OC Features
While the FX-777A-ZDSC doesn't have (or require) the elaborate vapor-chamber cooler XFX uses on its 7900-series cards, it has most of the other enhancements XFX applies to AMD's reference design: 2 ounce copper PCB, ferrite core chokes, and solid capacitors capable of operation up to 105 degrees Centigrade. As with the Tahiti-based cards, the Black Edition 7770 uses hand-selected GPUs that XFX says are in the "top 1%" and can reach higher clock speeds without having to increase the wattage being drawn by the card. XFX delivers the card pre-overclocked with a GPU speed of 1120MHz (as compared to a stock speed of 1000MHz) and a memory speed of 1300MHz (stock speed 1125MHz).
