AMD Radeon HD 7970 Overclocked to 1.70 GHz Core, 8.00 GHz Memory, Benchmarked
So you thought the 1.26 GHz core - 6.30 GHz memory feat was quite something, considering that Sapphire already has a card in the works that does 1.33 GHz core 5.73 GHz memory out of the box? Wait till you see the numbers an overclocker for the MyDrivers community achieved. With the right voltage assistance, coupled with the right kind of cooling (liquid nitrogen), the overclocker achieved a Radeon HD 7970 overclocked speed as high as 1700 MHz core, and 2000 MHz (actual) or 8.00 GHz effective GDDR5 memory speed, churning out memory bandwidth of exactly 384 GB/s. The best part is that this wasn't a hit-and-run feat, the setup was able to run 3DMark 11 and 3DMark Vantage. The scores are pictured below. Details of the volt-mod can be found at the source.
