Compatibility, service & archival notes
Reference launch specification describes a single Cypress GPU; board-specific revisions differ.
Inspect power leads, clearance, blower, and thermal condition. Preserve exact board BIOS; verify each output and OS-compatible Catalyst driver.
- Check signaling, slot keying, lane width, power pinout, board length, case clearance, airflow, and PSU requirements for the exact item.
- Use drivers for the device ID and target OS; preserve installer/firmware copies and record their source before updates.
- Do not power hardware with corrosion, cracks, damaged connectors, obstructed cooling, or suspected shorts; document condition before bench testing.
