Driver glitch limits overclocking of Nvidia's GeForce 7800 GTX chip

Modern hardware such as Nvidia's latest graphic chip generation support temperature monitoring features that automatically can decrease clock speed and even disable graphic cards when the chip gets too hot. This "software protection mode" however works in two directions, sources told Tom's Hardware Guide.

The card is not only shut down when temperatures get too high, but also when they fall below a certain level. This is especially the case when GeForce 7800 GTX cards are prepared for overclocking with water or liquid nitrogen cooling systems.

Nvidia confirmed in an email to Tom's Hardware Guide that the graphic chip will switch into software protection mode when die temperatures reach a range of 30 to 35 degrees Celsius. "There is an issue with our thermal detection software that doesn't let you supercool the chip to run overclocking tests," Nvidia's Nick Stam said.

Since its done by software, there would be a hack very soon.That move can also lead of more use of Modded Drivers, if they manage to get rid of this protection system.
