Biostar owners with an AM4 motherboard can run AMD’s Ryzen 5000G desktop APUs, code-named Cezanne, after a BIOS update. The company announced the updates in September 2021 for its 400 and 500 series boards, covering the X570, B550, A520, X470 and B450 chipsets.
What owners need to do
The update has to be installed before the new APU goes in, because an older BIOS may not recognize the chip. Biostar points owners to the download section of each motherboard’s product page to find the right file.
Biostar’s support table lists two BIOS versions for each board: one that can boot the APU and a later one with full support. The B550GTA, for example, is listed with B55AG201.BST as the version that can boot and B55AG730.BST as the version with full support, so owners should install the full-support file.
Why it matters
Ryzen 5000G chips combine Zen 3 processor cores with built-in Radeon graphics, so a compatible board can run a desktop without a separate graphics card. Getting that from an existing B450 or B550 board means an upgrade without replacing the motherboard.
BIOS versions change over time, so check the support page for your exact model before you update.
