Leadtek Geforce GT 220 Extreme Overclocking Experiment
Want to see what happens when you cool NVIDIA's new 40nm GPUs with liquid nitrogen? Well that's exactly what MadShrimps have done, by cooling their new Leadtek Geforce GT 220 with some -180°C LN2.
Here's an excerpt:
"The core frequency increased almost 1-to-1 with the temperature. As indicated on the previous page, due to memory failure below -100°C this card didn't work stable at 1300MHz. I'm sure that if we could take this card to -160°C or lower it could function at 1.4GHz+ MHz core frequency! Not that it would matter, though, knowing that the card is heavily bottlenecked by the memory frequency.
Another very important thing to note is the shader frequency of 3.4GHz, which is the highest I've EVER seen on any Nvidia graphics card, so until proven differently, I guess this is a world record."
