Overclocker Vince "k|ngp|n" Lucido has been able to increase the core clock frequency of an EVGA GeForce GTX 680 graphics card to 2002 MHz. This makes Nvidia's GK104 the first chip to exceed the 2 GHz barrier. The GDDR5 memory was overclocked to 7406 MHz effectively, significantly faster than the 6000 MHz stock speed. It does have to be noted that a 3D benchmark could not be run successfully at these speeds, having to decrease the core clock to a (still impressive) frequency of 1846 MHz. The memory speed was not cut back.
The rest of the system consisted of a Core i7 3960X processor (overclocked to 5.53 GHz), an EVGA X79 Classified motherboard, 16 GB of DDR3-2400 G.Skill RipjawZ memory and an EVGA 1500 W NEX power supply. Both the GPU and processor were cooled with liquid nitrogen. In 3DMark 11, a score of P16472 was reached, making it the current record holder on HWBot.
