I understand your situation clearly. You're trying to troubleshoot a motherboard issue by checking NVMe slot configurations without modifying BIOS settings. The problem seems to stem from the card not booting in the X16 slot after changing the PCIe configuration. After testing, you noticed the bus speed dropped to 8x 3.0 and then back to 8x 4.0 when switching back. This inconsistency suggests a possible mismatch between your BIOS settings and the actual hardware behavior. It might help to verify the correct PCIe version for your board and ensure the NVMe slots are properly recognized. If the issue persists, consider consulting the manufacturer's support or checking for firmware updates.
well now...this is an interesting thing that just happened i changed the pcie x16 biforcation or whatever it's called in the bios from 8 x 8 to auto and this happend i know have my 4.0 x16 bus in graphics and all my nvmes and ssd mounted
