Athlon 200GE with two m.2 NVME drives?

Jump to solution

Hello, I'm having some issues with m.2 NVME SSDs with the Athlon 200GE.

Situation: I have an Asus ROG Strix B450-I with two m.2 NVME drives. I was using a Ryzen 2700 without issue, but I sold that and switched to an Athlon 200GE as a placeholder until the next gen APUs are released.

When I switched CPUs, suddenly neither m.2 drive was recognized. After a lot of fiddling in the UEFI, including A UEFI update, I was able to trigger a setting which allowed the CPU PCIE lanes to be shared. After that, the m.2_2 drive (boot drive) was recognized, but still nothing for the m.2_1 drive on the bottom of the board.

I've heard that the Athlon 200GE has fewer PCIE lanes and that I should expect slower NVME speed, but should it support two m.2 NVME drives at once? FYI, I'm not using a GPU.

Here's the foot notes for that... Always check the footnotes....

Note

*1 The M.2_2 slot shares with PCIE x16. When M.2_2 slot runs in PCIE mode, the PCIE x16 slot will run at x8 mode.
*2 M.2_2 is unsupported when using these CPUs.
*3 Due to limitations in HDA bandwidth, 32-Bit/192kHz is not supported for 8-Channel audio.
