Installation and service notes
Confirm the exact CPU, minimum BIOS, DIMM type/capacity and supported slot/port mapping in the board-specific vendor support documents before purchase or installation. Socket fit is not proof of processor support; similarly named board firmware must not be cross-flashed.
Use ESD-safe handling, inspect the board for socket damage, leakage and corrosion, and keep loose screws or conductive debris away from the PCB. Check the case standoffs, PSU leads and cooler clearance against the manual before first power-on.
