NVIDIA NVFlash
NVFlash is a program for flashing the BIOS of Nvidia video cards. It is used to update the firmware stored in the EEPROM of the video adapter. The application also allows you to save copies of the current BIOS to a file or display its version.
What is NVFlash used for?
As mentioned above, NVFlash is used to reprogram the BIOS chips of supported video cards. Such a need may arise in one of the following cases:
- Freezes, spontaneous shutdown/reboot of the computer due to video card malfunctions.
- The presence of all kinds of graphic “artifacts” (color stripes, dead pixels, etc.) on the monitor screen connected to the problematic video card.
- Complete inoperability of the graphics adapter and others.
The NVFlash utility is also used to update the firmware of video chips BIOS to eliminate various errors in previous versions. The need for flashing is usually reported by the manufacturer of the video card based on NVIDIA chips.
Functions and features of the nVFlash 5.814.0 utility:
- Flashing the BIOS of the video card;
- Compatible with NVIDIA graphics adapters;
- Free distribution;
- Command line control;
- Low-level work with hardware.
Examples of NVFlash commands
The NVFlash utility allows you not only to flash BIOS video chips, but also to perform many other operations with the chip. Here are the three most important commands used to flash chips:
- nvflash -c: the command with the “-c” switch allows you to determine whether the existing video card model supports the flashing procedure.
- nvflash -b <file_name>: creates a backup copy of the current video chip firmware and saves it to a file called <file_name>.
- nvflash <file_name>: command to start the video chip firmware process, where instead of <file_name> The name of the firmware file is indicated.
You can familiarize yourself with the syntax and description of all other commands directly in the console by entering “nvflash” without any attributes or keys.
When using the NVFlash utility, it is important to keep in mind that incorrect handling of it can easily lead to various malfunctions in the operation of the video card or even its complete failure
