AMDVBFlash (ATIFlash)

AMDVBFlash, still widely known by its old name ATIFlash, is AMD’s command-line utility for backing up and flashing the video BIOS (VBIOS) of Radeon graphics cards. Most people searching for an amdvbflash download are rig owners who want a safe copy of each card’s BIOS, need to restore a card after a bad flash, or want to move a card onto an official BIOS revision from its board partner.

It is a low-level tool with no undo button. Used carefully, it is the standard way to save and restore AMD VBIOS images; used carelessly, it can leave a card that no longer posts. This page covers what the current build really does, how miners use it, and where its limits are.

AMDVBFlash at a glance

What it does

• Lists every AMD adapter in the system with its index, device ID, subsystem ID and current BIOS part number.
• Saves the current VBIOS of any card to a ROM file, which is the first thing to do before touching a card.
• Programs (flashes) a ROM file onto a selected adapter, one card at a time on multi-GPU rigs.
• Checks that the new image matches the card’s IDs and refuses mismatches unless you force it.
• Supports the newest Radeon generations in the 5.x branch, including RX 7000 and RX 9000 cards.
• Runs from an elevated command prompt; current Windows builds are command-line only (the last GUI build was 3.31, January 2022).

How miners use it

Back up every card in a rig

1. Open Command Prompt as Administrator in the folder where you extracted the tool.
2. List the adapters and note the index of each card.
3. Save each card’s BIOS to its own file and copy the files off the rig.

amdvbflash -i
amdvbflash -s 0 gpu0_original.rom
amdvbflash -s 1 gpu1_original.rom

Label the files with the card model and serial number. On a rig with six identical-looking cards, a backup is only useful if you know which card it came from.

Restore a card after a bad flash

1. If the card has a dual-BIOS switch, set it to the untouched position so the card works again while you prepare the restore.
2. Otherwise put the card in a second slot next to a working display card so the system can boot.
3. Find the card’s index with amdvbflash -i and program the saved original.

amdvbflash -p 1 gpu1_original.rom

Move to an official board-partner BIOS

1. Get the BIOS from the card maker’s support page for your exact model and memory type.
2. Back up the current BIOS first, then program the new image to the correct index.
3. Reboot, reinstall or reset the driver, and check clocks and memory size before restarting the miner.

The -f switch forces a flash when IDs do not match. It exists for recovery cases; using it to cross-flash a different board design is the most common way miners brick cards.

Install and first run

Windows. The tool comes as a ZIP archive with no installer. Extract it to a short path such as C:amdvbflash, open an elevated Command Prompt there and run the commands above. Newer AMDVBFlash builds rely on a kernel-mode driver; widely used redistributed packages add a small helper to install the driver only while you work and remove it afterwards, which is the safer habit. Close mining software, overclocking tools and monitoring apps before flashing so nothing else talks to the card.

Linux. AMD’s last Linux build is 4.71 from 2021. It still reads and writes older cards, but it predates RX 6000 refreshes and later generations, so for newer cards plan to flash on a Windows machine.

Where it comes from. AMD does not publish a public download page for AMDVBFlash; it ships the tool to board partners, and the builds people use are widely mirrored, most notably by TechPowerUp. Because there is no AMD page to compare against, check the archive’s checksum against the hash published by the site you trust before running it, and never run a “modded” build from an unknown uploader.

Common errors. “Adapter not found” usually means the command prompt is not elevated, the driver helper is not installed, or the card is not detected by Windows. “Failed to read ROM” can point to a write-protected or failing BIOS chip.

Limitations

• Flashing can brick a card and will usually void the warranty. Always keep the original ROM and know how to boot the system without that card.
• Radeon RX 5000 and newer cards check the VBIOS signature, so a hand-edited image will not run on them. On these generations the tool is for official images only; power and clock tuning is done in the driver or with tools like MorePowerTool.
• Custom memory-timing BIOS mods are a Polaris-era practice (RX 470/480/570/580). They still work there, but the risks are the same and modern drivers and miners have their own timing options.
• Closed source, no official changelog and no AMD download page, so you rely on trusted mirrors.
• Current builds are command-line only; Linux and DOS versions have not been updated for years.

AMDVBFlash vs alternatives

AMDVBFlash only reads and writes BIOS images; it does not edit them. For RX 5000 and RX 6000 cards, MorePowerTool changes power, voltage and clock limits through the driver without touching the BIOS, which is far less risky for tuning a rig. For older Polaris cards, Red BIOS Editor from igor’sLAB edits the image and AMDVBFlash then writes it. On NVIDIA cards the equivalent tool is NVIDIA’s own nvflash. If your interest is motherboard firmware rather than graphics cards, see UEFI BIOS Updater.

FAQ

Where can I get an AMDVBFlash download?

AMD has no public download page, so the tool is distributed through well-known hardware sites that mirror it. Use the latest 5.x build for current Radeon cards and verify the archive checksum before use.

Is AMDVBFlash safe?

The tool itself is AMD’s own utility, but flashing is risky by nature. Back up the original BIOS, flash only images made for your exact card, and never interrupt the process.

What are the basic AMDVBFlash commands?

-i lists adapters, -s saves a BIOS, -p programs one, and -f forces a flash despite an ID mismatch. Running the tool without arguments prints the full option list for your build.

How do I force flash with AMDVBFlash?

Add -f to the program command, for example amdvbflash -f -p 0 file.rom. Only do this when restoring a known-good image for the same card, because forcing a different design is a common cause of bricked GPUs.

Is there an AMDVBFlash for Linux?

Yes, but the last Linux build is 4.71 from 2021. It handles older cards; newer Radeon generations are best flashed with the current Windows build.

Does flashing a mining BIOS make mining more profitable?

Not by itself. On Polaris cards, tuned memory timings can raise hashrate on some algorithms, but whether mining pays depends on electricity cost, the coin price and the card, and on RX 5000 and newer cards custom BIOSes cannot be used at all.

What is the difference between ATIFlash and AMDVBFlash?

They are the same tool. ATI called it ATIFlash or WinFlash; after the AMD takeover it was renamed AMDVBFlash.
