Hello, I recently purchased this Mobo for the express purpose of running a dedicated server for storage of all my things i dont want on my main system. Im fine with setting up such processes -
Buuuut I require the ASRock B550 Taichi with its AMD Ryzen 5 5600G CPU to have my Asus Hyper M.2 x16 Gen 4 card function with all 4 SSD/NVMe drives on it fully accessible - and i cannot find were in BIOS i set the PCIe lanes to x4x4x4x4 so that all 4 SSDs are functional and seen by the BIOS and OS ? |

Hello,
It is difficult to tell where the option is, because it is usually included in AMD PBS, under advanced`. You have to set the NVME Raid Mode to enabled, then should have the option available. But since this changes with every new Agesa code Thje trick is that you require RAID mode, and then split up the PCIE slot in x4 x4 x4 x4 Please check the specs, Section Slots, because it depends on the CPU, how many PCIE lanes are available for each slot http://www.asrock.com/mb/AMD/B550%20Taichi/index.asp#Specification It has been tested on B550M pro4, so I guess it will work However you use a Cezanne CPU, and it depends on much slots are occupied. With PCIE1 and PCIE3 in use, bot slots have only 8 lanes, so can handle 2 M.2 cards Also there is not much to gain from 4 M,.2, since the PCIE speed is the limiting factor. Feel free to share your findings, on the forum, other users can benefit from it. |
