No, you read the title correctly.Users from ASUS ROG Forum (pass through Reddit) Apparently a way has been found to enable AMD Ryzen 5000 The (Vermeer) processor on ROG Crosshair VI-something that shouldn’t happen. Even more shocking is that the firmware comes from ASRock B450 Pro4 R2.0.
AMD initially only hoped that Zen 3 processors could run on the latest 500 series motherboards.After some confusion in the user base, the chip manufacturer finally backed down Allow Zen 3 chip Works on 400 series motherboards. However, AMD is determined not to include the 300 series motherboards in the support list.
This didn’t stop enthusiasts Modify official firmware Enable Zen 3 support. Of course, this means keeping the same firmware forever without losing future functionality and stability or bug fixes. But if you use Zen 3 to run a 300 series chipset, you may not worry about these things.
ASRock brings Zen 3 support to ASRock B450 Pro4 R2.0 through its 4.50 firmware, which you can download from the product page. According to ROG Forum users, the above firmware version is also applicable to ROG Crosshair VI. Obviously, the 4.80 firmware can also enable AMD’s Smart Access Memory (SAM) technology on ROG Crosshair VI for users who only need this feature.
We do not recommend users to flash the firmware from one motherboard to different models because they use different designs. There is no guarantee that all functions will work properly, and you may end up damaging the motherboard. But if you want to give it a try, forum users shared the following process:
- Download the firmware from ASRock website.
- Use Rufus to create a bootable DOS flash drive.
- Copy the firmware to the flash drive.
- Download AFUDOS (a BIOS flash utility) and copy it to the flash drive.
- Boot from the flash drive and use the “afudos nameofrom.rom /gan” command to update the BIOS (although the BIOS code does not match, /gan will still force the BIOS to write).
So far, there is no user feedback on whether ASRock firmware will reduce system stability or which functions (if any) on the motherboard will eventually be disabled. If you want to try this hack, please proceed with caution. Be sure to share your experience in our comments. Considering the risks, we prefer to sell the old 300 series motherboards and upgrade to newer models.
