Here is the requested output: $ sudo lspci -vv -s 01:00.0 | grep -i LnkCap LnkCap: Port #0, Speed 32GT/s, Width x16, ASPM L1, Exit Latency L1 unlimited LnkCap2: Supported Link Speeds: 2.5-32GT/s, Crosslink- Retimer+ 2Retimers+ DRS-
So the GPU clearly supports PCIe Gen5 x16 (32 GT/s). However, as shown before, `LnkSta` reports the link is always running at Gen1 (2.5 GT/s) on Ubuntu 24.04 with nvidia-driver-580-open, even if BIOS is forced to Gen4. On Windows 11 with GPU-Z, the card correctly runs at PCIe Gen5 x16. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2125583 Title: NVIDIA RTX 5080 runs at PCIe Gen1 speed on Ubuntu 24.04 with nvidia- driver-580-open To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-restricted-signatures-hwe-6.14/+bug/2125583/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
