PCIe Vs PCIe For High Data Transfer

PCIe and PCIe - Difference between x8 and x16 can i put a pcie 3 0 in a 4 0 slot It won't work well but it will work So, what I need is a NVMe x4 passive adapter card, which will plug the into a normal PCIe x1 slot, and candy glyph slot 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,

can you connect pcie 40 in 30 slot It should be backward compatible, but you will see less performance than if you had it in a PCIe slot since it runs at PCIe x8 instead
