How does the x570 chipset Link speed affect the performance of nvme drives with different PCIE generations? >
> I have a system with an x570 motherboard, a Ryzen 9 5950X CPU, a Gainward RTX3080TI GPU, and three nvme drives: a Crucial T500 2TB and a Corsair Force MP600 1TB connected to the motherboard's nvme slots, and a Samsung 970 Evo Plus 1TB connected to a PCIE3 extension card. The motherboard's nvme slots and the GPU slot are set to PCIE4, while the extension card is set to PCIE3. >
> I noticed that the nvme drives connected to the motherboard have inconsistent and low read and write speeds and high access times when the chipset Link speed is set to PCIE4. However, when I set the chipset Link speed to PCIE3, the nvme drives connected to the motherboard have normal PCIE3 speeds and access times. Is this a known issue with the x570 chipset? Does it have trouble handling devices with different PCIE generations simultaneously? How can I fix this problem?
