Asus has released a tweak program of sorts for their V3400 TNT video-card. This thing lets you change the core speed and memory speed on the V3400. Tweak Monkey also tells me that this program searches for the V3400 driver, so you cannot use this unless you have one. And remember, there's no such thing as risk-free overclocking.
