Warning! The heatsink becomes very hot when the system is on. NEVER touch the heatsink with any metal or with your hands.

Processor Sequence

If only one CPU is to be installed, it must be installed in the CPU 1 socket, see “CPU socket 1” in “Mainboard layout” for more information. In this case, the CPU 2 socket no longer requires a termination module. When installing multiple processors, install CPU 1 first, then CPU 2.
