Compatibility, service & archival notes
Check PCIe slot/firmware support and both auxiliary power connectors. Confirm cooler thickness/length and airflow in the chassis. Older operating systems may need a legacy Catalyst/Crimson package; choose a driver supporting the card device ID and OS. Display output combinations and adapters vary by board.
- 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.
