nVFlash — Download

Command line firmware update app designed for NVidia adapters to perform additional tasks.

Firmware update utility for NVidia display adapters that flashes the BIOS of your graphics card from the command line.

nVFlash (NVIDIA Firmware Update Utility) is a command-line utility that is used to update the firmware on NVIDIA graphics cards. It allows you to update the firmware on the graphics card to the latest version, which can improve performance and stability.

nVFlash is designed to be used by advanced users and professionals, as it requires a certain level of knowledge and expertise to use effectively. It is not a graphical application, and is instead run from the command prompt.

It can fix every brick situation that is the result of incorrect contents of the internal eMMC.

How to use nVFlash

To use it, you will need to download the firmware update file from the NVIDIA website and save it to your computer. You will then need to open a command prompt and navigate to the directory where the firmware update file is located. From there, you can use a variety of different command-line options to update the firmware on the graphics card.

1. Download the firmware update file from the NVIDIA website and save it to your computer.

2. Open a command prompt and navigate to the directory where the firmware update file is located.

3. Type «nvflash» followed by the appropriate command-line options for the firmware update.

4. Press Enter to start the firmware update process.

To sum it up

Overall, nVFlash is a powerful utility that allows you to update the firmware on NVIDIA graphics cards, and can be useful for improving the performance and stability of the graphics card. However, it is intended for advanced users and professionals, and may not be suitable for all users.

What is 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.

NVFlash supports BIOS flashing on the following NVIDIA graphics cards:

  • GeForce RTX 3090, RTX 3080, RTX 3070, RTX 3060 Ti, RTX 3060
  • GeForce RTX 2080 Ti, RTX 2080, RTX 2070, RTX 2060, GTX 1660, GTX 1650
  • GeForce GTX 1080 Ti, GTX 1080, GTX 1070, GTX 1060, GTX 1050
  • and many more, including flashing the BIOS on older NVIDIA devices.

Warning!
There is a real danger that the display adapter will not boot and fail to boot the system if the update process is interrupted due to a program crash, power failure, if you manually restart the computer, or if you update the adapter with the wrong firmware image. For this reason, care should be taken when using this utility.

How to use NV Flash

Step 1 — Download the program

Download the program from the official website of TechPowerUp. Or download from the guru3d release.

Step 2 — Run a command line and make a copy of the BIOS

Extract the .zip archive to the root of the system drive C . The file nvflash64.exe must be located at the path C:\ .

Run a command prompt as an administrator.

  1. Click on the search icon.
  2. Type in the bottom search bar CMD .
  3. Select «Run as administrator».

Go to the directory with the program nvflash64.exe . To do this, enter the command: 

 cd C:\

Command result:

Now save a copy of your video card’s current BIOS. Enter the command: 

 nvflash64 -b bios. rom

You will see this window. A copy will be stored on disk C:.

If your program is called not nvflash64 but nvflash — then use this name in commands.

Step 3 — flash the new BIOS

In the same command line, remove the flash protection with the command: 

 nvflash64 -protectoff

You will see the inscription: Remove EEPROM write protect complete :

Flash the video card with a new BIOS. It should be on disk C: and named newbios.rom . Enter the firmware command: 

 nvflash64 -6 newbios.rom

The program will report: Update successful.

A reboot is required for the update to take effect. .

Not working?

If the program does not work or does not see your video card, try the following steps.

protectoff

You may have forgotten to remove the protection: 

 nvflash64. exe --protectoff

Force flash — forced flashing

Use key f if you need forced flashing. 

 nvflash64.exe -f -5 -6 bios.rom

You can cancel all checks/protections using: 

 nvflash64.exe -j -4-5-6 bios.rom

The numbers here are the IDs of the devices in the system.

No nvidia display adapters found

With this error, the program does not see the video card. You need to explicitly specify which device you want to flash (device bus ID).

nvflash64 with key -and should list ALL good GeForce video adapters.

To do this, try to find out the bus ID of the device and flash again with the command: 

 nvflash64 -4 -5 -6 newbios.rom

Also try using the version of NVIDIA NVFlash with board ID mismatch disabled.

Attention!
So that if the command says you must enter the file name. The very word and brackets are not written!

Example: 

 nvflash64 [options]

Spelled like this: 

 nvflash64 -b bios.rom

Option -b allows you to make a BIOS backup.

Full list of options

Where can I get the DOS version?

NVFlash must be used in DOS mode when you boot your system. So use an MS-DOS boot disk and just copy this tool onto it.

pci subsystem id mismatch error

The PCI subsys ID is the model of the card. Use the DOS version to resolve the error.

Also make sure you have unlocked BIOS: 

 nvflash64 -protectoff

Use key -6 : 

 nvflash64 -6 vbiosname.rom

The -6 command allows you to undo the PCI subsystem ID mismatch. In case of a mismatch, you need to confirm the action with the «y» key.

Note.
Users with non-US keyboards may need to press «z» or similar because «y» is not in the same place for all keyboard layouts.

SLI users will need to flash each card separately. The concept remains the same, but you will need to use the appropriate adapter index to flash the card. How to determine the adapter number. described above.

Flashing happens like this: 

 nvflash64 -i [index] -6 vbios.rom

[index] is a number, namely the index you found with nvflash64 -a .

So, an example of a command for flashing a card with an index of 0: 

 nvflash64 -i0 -6 vbios.rom'

When the monitor starts blinking, just wait until the message that everything is ready appears. Then reboot with Ctrl+Alt+Del and remove the USB stick.

Command format not recognized

What to do in this case? It’s simple, the program tells you that you entered the wrong command. Check each letter again and correct the mistakes.

Not an internal or external command

Make sure you run the command from the same folder as nvflash64 .

nVFlash for Windows 10, 7 and 8 (x64/x32)

Description

How to download the program:

  • Instruction video

nVFlash is a utility for device manufacturers and developers that allows you to work with the BIOS firmware of a computer video card. The program is released by NVIDIA and is designed primarily for their graphics adapters.

nVFlash is compatible with 32 and 64 bit Windows 7, 8, 10, Linux, DOS systems. It is recommended to use the latest OS version. The program is often used by video card manufacturers and system developers.

Since video cards have a processor and RAM, a separate BIOS is required for their interaction. He is responsible for the interaction of applications and drivers with hardware. The firmware also monitors temperature, cooling system, voltage and frequency.

The nVFlash utility allows you to read, write, erase and format the BIOS of the NVIDIA graphics card. The application works at a low level directly with the graphics adapter. Even with incorrectly written firmware, the user can restore the device to working capacity. Therefore, write errors caused by turning off the light, loading the BIOS from another video card, or completely uninstalling it will not disable the adapter.

To flash under DOS, you need to write nVFlash to a memory card with FreeDOS and boot from it. If this is not possible, you can flash the BIOS under Windows, which is less secure.

Functions and features of the nVFlash 5.567.0 utility:

  • Video card BIOS flashing;
  • Compatible with NVIDIA graphics cards;
  • Free distribution;
  • Command line control;
  • Low-level work with iron.
