Gen3 4U Value 10-Slot - GPU Expansion

As Zef said, PCI-e is backwards compatible You can put a PCI-e GPU into a slot or a PCI-e GPU into a slot, it'll just run

Apparently the cross-compatibility and quality are quite variable PCIe = gen3 seems easier than gen4, though, and for your needs it sounds The PCIe riser cable supports bit rate speeds of 16GTs While providing double the bandwidth of PCIe , the Gen riser cable remains backward

slot dimension callout Yes, it'll be perfectly compatible with gen PCIE slot  We suspected there may be a small performance advantage with high-end parts such as the RTX 3080 and 3090 when using PCIe over ,
