CAUTION: Heatsink retaining screws should be tightened or loosened in diagonally opposite

or screws. Use the wrench supplied with the system to reduce the possibility of overtightening the
screws.

CAUTION: When returning a damaged system board to HP, always install all processor socket
covers to prevent damage to the processor sockets and system board.
