Do i need cpu for bios update?
I was thinking about getting a new motherboard and CPU (Ryzen 5 5600X). I heard some motherboards allow you to update the BIOS without needing a CPU. My question is, does the ASRock B550 Phantom Gaming 4 require a CPU for that update?
This interface cannot perform BIOS updates when the processor isn't connected.
New boards must be updated immediately, meaning manual updates are likely unnecessary. No reference to BIOS flashback was found for the board; for the B550 Phantom Gaming 4, you should check the CPU documentation at https://www.asrock.com/mb/AMD/B550 Phantom Gaming 4/#Specification
You visit Asrock's site, select your motherboard type, and navigate to Support then CPU Compatibility List. You locate the B550 Phantom Gaming 4 model and spot the 5600x entry. The BIOS information indicates it requires version 1.20, originally released on August 24, 2020. The next updates came in October and December. Considering most boards made after December 2020 come with at least BIOS 1.40, you wonder if your planned purchase was bought before or after that date. Given the popularity and affordability of this model, it's likely a newer board from 2021 with a more recent BIOS installed.
It includes a flashback function, but this particular board doesn’t support it. A CPU must be installed to upgrade the BIOS. You might attempt to operate it without the update initially. It could already have a BIOS version that supports at least Zen 3, depending on its release date. If it fails to start, you’ll need to install the update. For assistance, reaching out to AMD may provide an old CPU for the update, which you can return once completed. Alternatively, you can bring it to a repair shop that handles BIOS installations.
Question your need for a BIOS update for a 5600x now, especially in 2023... The 5600x was supported from the very first BIOS on the B550 chipset. Make sure to attach the CPU power cable and the 24-pin connector, insert just one stick of RAM into the farthest slot from the CPU socket. Ensure the motherboard is secured with standoffs and that the back doesn’t touch the case metal except at screw points. Since the CPU lacks integrated graphics, the video connectors on the motherboard won’t function. You’ll need a dedicated video card and a connected monitor to display video. When the system boots for the first time, it may take 20–30 seconds or longer—patience is key. If it doesn’t boot within that time, check for status LEDs or listen for any beeps from the board; these codes might reveal the issue.
