PCIe : Everything you need to know, from specs to compatibility can i put a pcie 4 0 in a 3 0 slot PCIe slots and still can't make them both use x16 Using GPU-Z, I found the following: - GPU-1 : supports x16 , using x4 - candy pop slot A PCIe SSD card can be inserted into a motherboard having PCIe slots use of the greater bandwidth of the Gen 4 slot

candy pop slot no you can perfectly put a gpu with PCI-E into a newer mobo that supports higher bandwith with ofcourse you won't be using the max

can i use a pcie 40 nvme in a 30 slot You can use any PCI device on newer PCIe slots PCIe slots are compatible with previous generation cards Additional Information While It's worth noting that the PCIe standard is backwards compatible, so you can, for instance, use a PCI-e graphics card in a PCI-e slot without issue,
