What is the difference between PCIe Gen 3 and PCIe Gen 4?

Often they can also function as a home server With gigabit or pcie x1 nvme port adapters sound an interesting way of avoiding

I have tried several PCIe cards in my x370 Gaming Pro Carbon x1 slots, and I am not able to get either of them to function properly

pcie4 slot But it's a full-fledged Windows PC with an Intel Alder Lake-N processor, 12GB of LPDDR5-4800 memory, and an 2242 slot for solid state

pcie2 slot I recently swapped out my old MB for a MSI MEG X570 Unify motherboard and and now my Intel Wi-Fi 6E AX210 based PCIE Adapter won't function
