Compatibility, service & archival notes

Requires an x16-length PCIe slot with adequate clearance and two 8-pin leads for the reference card. Check chassis length/thickness, PSU quality, UEFI and a supported driver. Outputs and dimensions on non-reference models must be checked against their own model numbers.

  • 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.
