Although Nvidia's latest top-of-the-range offering, the GeForce 8800 GTX graphics card, that has just been released offers incredible performance, there are people not satisfied with it and looking forward to push it even further. Just about a week after the formal launch, tens of overclockers have already shared their experience all over the Web.

Before attempting to increase the clock-speeds, there are a number of facts which should be considered seriously. Nvidia's code-named G80 graphics chip not only boasts with 681 million transistors and is clocked at 575MHz/1350MHz, but is also made using 90nm process technology and dissipates nearly 150W, meaning that for the highest overclocking results one should choose only the most efficient methods for cooling the GPU.

VR-Zone web-site with the help of volt-modding and dry ice cooling has managed to overclock a pair of EVGA 8800 GTX ACS3 Edition graphics boards working to 822MHz/1240MHz for GPU/memory and obtain a score of 22799 in 3DMark06 benchmark using two of such boards in SLI tandem.

?Now let's do some Dry Ice runs! With -40C cooling, I got this card to 842MHz Core, and 1240MHz Memory,?writes the author in regards to his single GeForce 8800 GTX graphics card overclocking experience.

The article contains a lot of detailed pictures of the voltmodded boards and the system used which may prove helpful for those who are looking forward to similar attempts.
