Quote: Another incredible thing about this card is that it was unlockable – meaning that I was able to flash it to an HD6970 BIOS, unlocking the total 1536 shader cores over the stock 1408. With the extra 10% of shader cores at my disposal, I reran the overclocked benchmarks and discovered a steady jump in performance by anywhere between 6%-8% running at the same 1010/1500MHz. Granted, not all cards can do this from the factory, as they are physically cut. I cant say whether all these cards are unlockable, but it doesnt hurt to try.
