Update information for motherboard BIOS (B450)
Hi Sam,
Your system is a Gigabyte B450 Aorus Elite with BIOS v1 from 2019, updated for Ryzen 5 3600. You’re wondering about the correct update path and whether you need to upgrade to newer BIOS versions like F50 or F67i. Also, you mentioned an EC Firmware Update Tool—check if it’s installed. The embedded controller version is listed as 255.255 in system info. Let me know if you need step-by-step guidance!
According to the guidelines, you should be able to simply switch directly to F67i.
I concur. Contemporary motherboards typically don’t allow incremental updates either. Just install the desired BIOS and that’s sufficient. Clearing the CMOS memory after a flash helps reset the BIOS to its default configuration. A benefit is the ability to update to an older BIOS version when necessary.
I see a difference. The AMD B450 boards presented a unique challenge since their original 128 mbit flash chip couldn't accommodate the full BIOS code for AM4 processors. Eventually, they released an updated BIOS that removed support for early Zen-based AM4 chips and even some first-gen Ryzen models. Because of hardware constraints, some boards split the flash memory into two sections—similar to a dual-drive setup—and employed methods to access only one part based on processor generation. This explains the red notes in BIOS release versions indicating required updates. Later versions like F50 demand the new chip arrangement, while F42a was likely a test version before F50. If you lack four RAM sticks, the EC FW Update Tool isn’t necessary; for four sticks, simply remove two and update with just two. I recommend updating chipset drivers via the official AMD site (https://www.amd.com/en/support/download/drivers.html). Obtain a 8-32 GB USB drive, format it as FAT32 using Windows, and download BIOS versions such as F50, F53, F61, F66. Place the extracted files on the USB. Generally, update the BIOS whenever the AGESA version changes noticeably. F66 is the current stable release, while F50 is the latest beta. The TPM updates might be required for Windows 11 support—if installation fails, consider updating the BIOS as well. After installing, restart, enter BIOS settings, and use the built-in programmer to select and program each version sequentially, beginning with the oldest. Reboot after each update.
You completed the tasks I suggested today, everything worked smoothly. The bios is set to F66 on Windows 11, and thank you once more!
