EVGA has to be feeling awfully confident in its videocards. Not only does EVGA allow its registered users to overclock its GPUs without invalidating the lifetime warranty, but its giving owners the tools to do so.
EVGA's Precision overclocking utility already makes it stupid simple to increase the core, memory, and shader clockspeed on its videocards, and now the company has made available its GPU Voltage Tuner utility to registered owners. With it, GTX 295, 280, or 260 graphics card owners can set custom voltage levels, potentially paving the way for greater overclocking headroom. Of course, increasing voltages also increases the risk of killing components, and so far EVGA doesn't allow sliding the tuner into the red zone, a feature which may be unlocked in a future version, EVGA states in its FAQ.
A prerequisite for using the utility is installing GeForce 181.22 drivers or later. EVGA notes that "it is possible to damage your hardware while adjusting your GPU Voltages - use at your own risk." We'd have to agree.
