I stumbled on this  A620M with PCIe Gen5 M.2 SSD support? If this is legit  Can anyone confirm? |

The PCIe lanes are provided directly by CPU, so they have nothing to do with the chipset. The only two things that could prevent it from running at PCIe Gen5 mode are: 1. Software (BIOS/UEFI). 2. Motherboard traces just not up to par to support the PCIe Gen5 speeds. I imagine it's not worth the extra effort to re-design ALL of the traces on a motherboard, just to offer an A620 variant, so many board might just use the same design for the main m.2 slot traces. Future BIOS update will likely disable PCIe Gen5 functionality, regardless of whether the physical connection can or cannot support it reliably. Similar thing happened when Ryzen 3000 series (Matisse) was released, with some of the older 300 & 400 series boards able to run the GPU slot at Gen4 speeds, but future BIOS releases prevented this from happening. |
