Check the PCIe link speed requirements for PCIe 3.0 X16. Ensure your device meets the specifications.
I added a second NVMe SSD recently and haven’t checked it yet. I’m not sure if my main PCIe 16 slot is sharing bandwidth only with the secondary slot. Is 8 Gbps under load suitable for PCIe 3.0 x16? It’s 2.5 Gbps when idle, sometimes reaches 5 Gbps, and peaks at 8 Gbps during gaming. GPU-Z indicates it should be at PCIe 3.0 x16. I’m not even sure what the Current Link Speed means. Meanwhile, my wife’s machine (Z390, 8700, 5700XT) reports 16 Gbps for both current and max speeds.
Found something interesting... It seems you're switching between different groups or systems. Your wife's setup appears to be a bit confusing, but I'm not entirely sure what you mean. The specs you shared look technical—PCIe versions and transfer speeds—but it's hard to grasp without more context. Total bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s. Data transfer rates: PCIe 3.0 = 8.0GT/s, PCIe 2.0 = 5.0GT/s, PCIe 1.1 = 2.5GT/s. Dec 15, 2017
I understand it slows down in idle, likely dropping to PCIe1 and PCIe2 during lighter tasks. This metric probably shows how much GPU bandwidth it can use—around 16 GT/s on PCIe4. It makes sense since PCIe4 supports that speed, but your wife's motherboard might not be configured or capable of handling it properly.
