Compatibility, service & archival notes
Because it is wired for PCIe 4.0 x8, a PCIe 3.0 host may reduce link bandwidth; confirm motherboard slot wiring and firmware. The card requires a supported UEFI/driver environment and a suitable 8-pin supply lead. Match display outputs to monitor inputs and the partner card’s actual panel.
- Check the exact slot keying/signaling, board dimensions, auxiliary-power pinout, PSU guidance, airflow and display outputs for the specimen; connector appearance alone does not establish compatibility.
- Install a driver supporting the recorded device ID and target OS. Preserve the original driver and firmware versions before making changes.
- Record board partner, PCB and cooler revision, device/subsystem IDs, BIOS, adapter set and physical condition. Do not power a card with damage, corrosion, obstructed cooling or suspected shorts.
