Compatibility and installation caveats
Requires a server/workstation with validated 300 W GPU power delivery and strong directed airflow. The passive card must not be treated as a self-cooled gaming board. Confirm 16-pin cable rating, seating and bend clearance. DisplayPort availability can depend on chassis and firmware configuration. Use a supported NVIDIA data-center/RTX Enterprise driver and validate OS, vGPU and CUDA requirements.
- Check the exact card manual and server qualification list for slot, power pinout, chassis clearance, airflow and firmware support before installation.
- Preserve the driver and firmware source/version used for evaluation; do not assume consumer GeForce software or an unqualified workstation supports data-center features.
- Power only a board with undamaged connectors and verified supply/cable pinout; record condition before bench testing.
