How Many PCIe Lanes Do You Really Need?

website can i run a pcie 4 0 in 3 0 slot PCIe 4 is backwards compatible with gen 3, 2 & 1, and you will get at least the same performance from putting a drive in a slot as you can''t use the m2 ssd inserted in the expansion slot ps5 Apparently the cross-compatibility and quality are quite variable PCIe = gen3 seems easier than gen4, though, and for your needs it sounds

can i run a pcie 4 0 in 3 0 slot You cannot make a PCIe device turn into So if that card was a PCIe card, then the device will run at PCIe x4 It's just like if  PCIe slots feature the same pin layout and thus are forwards and backward-compatible However, a PCIe card slotted into a PCIe slot will  PCIe is backward compatible It's also forward compatible So, you can insert PCIe expansion cards into PCIe slots, but your data
