System requirements for installing the NiBiTor program (NVidia BIOS Editor)
Before using the BIOS editor for graphics chips, you should first make sure that your equipment meets its system requirements:
- OS – Windows 2000, Windows XP, Windows XP-64, and Windows Vista.
- Video card – devices based on GeForce FX 5600 and newer versions of graphic processors.
If there are no problems with compatibility, then you can download the program from proven reliable sources.
Functionality and capabilities of the NiBiTor program
Using the NiBiTor program (NVidia BIOS Editor), you can read the BIOS image directly from RAM and change various parameters:
- clock frequency of the graphics processor and memory for different performance levels;
- the value of time delays (timings) of the video memory;
- GPU supply voltage for different performance;
- fan operation parameters for different performance or temperature levels;
- video card protection response temperature (this option is available for video cards that have a thermal monitoring option);
- video BIOS settings and message text when turning on the PC;
- SubDevice ID and SubVendor ID parameters, which determine the model and manufacturer of the video card;
- AGP bus operation parameters.
In general, with the help of the NiBiTor (NVidia BIOS Editor) program, advanced users can fully control some advanced functions and capabilities that are provided in the firmware of video cards. As a result, the user will receive additional performance. In particular, it will be possible to adjust memory delays and access extensive information about the operation of the equipment, you can adapt the boot parameters, change the fan speed, and get additional stability of the equipment.
