CAUTION
CPUs are extremely sensitive to electrostatic discharge and therefore
must always be handled with care.
▶
After a CPU has been removed from its protective sleeve or from its
socket, place it upside down on a nonconducting, antistatic surface.
▶
Never push a CPU over a surface.
CAUTION
▶
Only CPUs of the same type may be used on the system board.
That means the number of the internal CPU cores as well as the
primary clock and the QPI frequency have to be the same.
▶
For dual operation, use a suitable multiprocessor OS.
