Anyone can slap on an aftermarket heatsink and call it a day but Palit's implementation of two BIOS chips on this video card was a welcome improvement. I am notorious for killing video cards and I've had my fair share of video cards that I've bricked from bad BIOS flashes so having two BIOS chips on the card doesn't immediately render it useless after a bad flash. Palit features two BIOS profiles, one with stock clocks and one slightly overclocked. The stock clocks are 750MHz on the core and 950MHz on the memory. Palit bumps this up to 775MHz on the core and 1000MHz on the memory for a modest and safe overclock.
