Kepler VBIOS Tuner



What is Kepler VBIOS Tuner?




Kepler VBIOS Tuner is a software tool that allows you to modify the VBIOS of your NVIDIA Kepler-based graphics card. But what is VBIOS, and what is Kepler?


What is VBIOS?




VBIOS stands for Video BIOS, which is a firmware that controls the basic functions and settings of your graphics card, such as clock speeds, voltages, fan speeds, power limits, etc. The VBIOS is stored in a chip on your graphics card, and it is loaded into memory when you boot up your computer. The VBIOS can be updated or flashed with a new version to fix bugs, improve compatibility, or add new features.


What is Kepler?




Kepler is the codename for the microarchitecture that powers the NVIDIA GeForce graphics cards of the GTX 600 and GTX 700 series, such as the GTX 690, GTX 680, GTX 670, GTX 660 Ti, GTX 660, GTX 780 Ti, GTX 780, GTX 770, and GTX 760. These cards were released between 2012 and 2014, and they offer high performance and efficiency for gaming and other applications. Kepler cards are based on a 28 nm process technology and use PCI Express 3.0 interface.


What can Kepler VBIOS Tuner do?




Kepler VBIOS Tuner can help you modify the parameters of your Kepler-based graphics card's VBIOS, such as:



  • Clocks: You can adjust the core clock, memory clock, and boost clock of your graphics card to increase its performance.



  • Voltages: You can adjust the core voltage, memory voltage, and boost voltage of your graphics card to increase its stability or lower its power consumption.



  • Boost Limits: You can adjust the boost limit of your graphics card to control how high it can boost its clock speed under load.



  • Fan Speeds: You can adjust the fan speed curve of your graphics card to control how fast and loud it spins under different temperatures.



  • Power Limit: You can adjust the power limit of your graphics card to control how much power it can draw from your power supply.



By modifying these parameters, you can customize your graphics card's performance and features according to your needs and preferences.
