Only weeks have passed since the official release of NVIDIA's new top-of-the-range GeForce 7800 GTX 512 graphics processing unit (GPU), but already now computer enthusiasts set the world's records in terms of overclocking the parts. While this piece of hardware is only a dream for some users, some hardcore fans use a pair of such graphics cards for their extreme overclocking and record braking.

Famous Swedish overclocker Marcus Hultin aka Kinc in cooperation with Gainward and Overclokk companies has managed to set a new world record in 3DMark05 benchmarking application. A score of 18614 was achieved on a heavily overclocked testbed powered by AMD Athlon 64 FX-57 chip clocked at 3928MHz, DFI LanParty NF4 SLI-DR mainboard, 2x512MB Corsair XMS3200LL memory modules as well as two Gainward Ultra/3550PCX XP graphics boards.

In order to show the world's record result Kinc had to significantly overclock a pair of Gainward Ultra/3550PCX XP graphics cards running in SLI setup. The frequencies on each card were set at 779MHz for GPU and 2052MHz for memory. The system was cooled by cascade compressor cooling.

Until now world's highest 3DMark05 result was 17433. It was obtained on two overclocked GeForce 7800 GTX graphics cards in multi-GPU SLI mode.

The performance level of two ATI RADEON X1800 XT graphics cards running in the CrossFire setup as well as overclockability of such a system is still to be seen.
