Hi @all
My Sys has a ROG Strix B450-E Gaming MoBo, and the M2_2 Port will not detect the inserted SSD. Windows runs on the on M2_1 inserted SSD, it's a WDC Green 240 GB, but the other Port seems to be 'dead' 

Ok, 2 things:

A) the m2_2 (the bottom one) will only run if you use a non-APU cpu, doesn't seem to be the case tho?
B) the m2_2 slot is nvme *only*. WD Green m.2 ssd's are SATA, and those can't be run from the m2_2 slot.

Taken from the manual:


• For AMD Ryzen™ 2nd Generation / Ryzen™ 1st Generation Processors: - M.2_1 supports PCIE 3.0 x4 and SATA mode M Key design and type 2242 / 2260 / 2280 storage devices.
- M.2_2 supports PCIE 3.0 x4 M Key design and type 2242 / 2260 / 2280 / 22110 storage devices*.

• For AMD Ryzen™ / Athlon™ with Radeon™ Vega Graphics Processors**
- M.2_1 supports PCIE 3.0 x4 and SATA mode M Key design and type 2242 / 2260 / 2280 storage devices.

* M.2_2 socket shares bandwidth with PCIE x16. When M.2_2 slot runs in PCIE mode, the PCIE x16_1 slot will run at x8 mode.
** The M.2_2 socket is not supported for these CPU
