NVIDIA GFX card partner Biostar have just announced their new V-Ranger (or "Voltage Ranger" software tool), providing the first ever VGA based dynamic regulation. This allows one to dynamically control the voltage of their GPU and memory to achieve either the best overclocking results or lowest power consumption.
For more details, check out the full press material here folks.
Today, BIOSTAR launches its new tool called V-Ranger for optimizing the best voltage, frequency and temperature values of each individual card. V-Ranger stands for Voltage Ranger, which is the first VGA based dynamic voltage regulation in the world. V-Ranger makes the concept of "power-on-demand" a reality. A powerful tool that can dynamically control the voltage of GPU and memory to achieve either the best overclocking results of the GPU or the lowest power consumption and temperature value of the card. The lower temperature will translate into a longer lifetime of the VGA card with enabled V-Ranger function. The V-Ranger will revolutionize the way power-users can overclock their graphic cards and utilize available power. BIOSTAR has set the new standard for a full VGA overclocking experience high. This technology will finally enable every power-user to control the most important settings of his/her VGA cards.
