ROG STRIX X670E-E M.2_2 won't detect nVme SSD in this slot

Hi,

when I turn on my PC this SSD is not detected (M.2_2 slot). I must restart the PC and then this SSD is online. This happend in the last 3 weeks 5 times.

Today with new anomaly when I restarted PC (after this first boot) and just trying to enter BIOS I saw only my 3 nVme (M.2_1 / M.2_2 / M.2_4). All other SATA HDD were not visibled in BIOS but when I entered to Windows I normally saw these HDD.

BIOS: 0925

CPU: 7950X3D

RAM: F5-6000J3038F16GX2-TZ5NR - G.SKILL 32GB KIT DDR5 6000MHz CL30 Trident Z5 NEO RGB AMD EXPO with EXPO I enabled.

I have the same problem, I must shut down the power supply in order to detect the drive. I have a similar system as you, it just randomly stops. I don't know what to do.

When I updated BIOS on newer version I never had this problem again. Its maybe only some bug in 0925 BIOS.

.. but now is latest 1416. Try with this BIOS.
