Hello,
I am using the Asus prime B550m-a motherboard with AMD 5500 cpu and RTX 2060S graphics card. I am now upgrading my storage to include two additional MVMe SSd drives. Hence I am trying to use my graphic cards (pcie4.0 x16) and two NVMe drives (pcie 3.0 x4 and pcie 4.0 x4) in the most optimum way. I need to know how the pcie4.0 and pcie3.0 lanes are shared/configured by my motherboard. I have read the motherboard manuals but did not come across this information.
In my search, I have come to know that some motherboards are designed to directly link the pcie x16 slots to the CPU, while other pcie lanes are shared between the pcie x4, x2, x1 and m.2 slots, RAM, SATA, etc. and some lanes are used by motherboard itself.
Hence I would really like a technical explanation on the pcie configuration specific to my motherboard, in particular, whether there are dedicated lanes for graphics card, RAM and NVMe, so that I can buy the NVMe drives accordingly.
Many thanks
