Anandtech 的編輯跑去問了 AMD 關於主機板廠修改 BIOS
在 3xx, 4xx 系列主機版開啟 PCIe 4.0 的看法
AMD 的回答是:
Our plan is unchanged. For the reliability and consistency reasons cited at
Computex, we still intend to disable PCIe Gen 4 for pre-X570 motherboards.
That AGESA is being released to motherboard manufacturers soon.
為了穩定性和一致性，他們還是不會開啟 3xx, 4xx 系列主機版 PCIe 4.0
未來的 AGESA 會封鎖此功能。
As things stand, any boards that currently support the feature would be using
pre-release AGESAs, and as we’ve seen with our own BIOS issues, the Ryzen
3000 BIOS situation is still evolving fast. So with AMD intending to
permanently disable the feature – and prevent any workarounds
編輯提到目前支援 PCIe 4.0 的舊主機板都是靠 beta 的 AGESA，
穩定性還是有問題。未來AMD會禁止這項功能，並且避免被主機板廠繞過 (ASRock 表示:)
