EVGA today made its GPU Voltage Tuner (GVT) software utility official. The utility allows end-users to control the voltage of the graphics processor, a significant factor when it comes to overclocking. Within safe limits, increasing the GPU voltage facilitates higher maximum GPU core and shader clock speeds. The utility keeps in mind the majority of users that doesn't understand the specifics of voltage control, and its impact on overclocking.

Using a simple slider, the user can set the vGPU voltage from 0.82V to 1.18V and beyond, depending on the accelerator. The resolution of the scale is in milli-Volts, although the resolution of the slider may differ. Initial tests have shown even simple increases in voltages to send the maximum overclock for the core speed up by as much as 100 MHz. The initial graphics card support-base includes the GeForce GTX 260, GTX 280 and GTX 295 series accelerators by EVGA. Future releases may expand the support base. The application is available exclusively to registered users of EVGA graphics accelerators, and can be downloaded from here.Extended graphics card support list follows.
