X CPU
The system board is equipped with a surface mount LGA 3647 socket. This socket is exclu-
sively designed for installing a LGA 3647 packaged Intel CPU.
Important:
1. Before you proceed, make sure (1) the LGA 3647 socket comes with 2 protec-
tive caps, (2) the caps are not damaged and (3) the socket's contact pins are not
bent. If the caps are missing or the caps and/or contact pins are damaged, con-
tact your dealer immediately.
2. Make sure to keep the protective caps. RMA requests will be accepted and pro-
cessed only if the LGA 3647 socket comes with the protective caps.

Note:
A boxed Intel
processor already includes the CPU fan and heat sink assembly. If
®
your CPU was purchased separately, make sure to only use Intel®-certified fan and
heat sink.

Installing the CPU, Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circula-
tion across the CPU and heat sink, the CPU will overheat damaging both the CPU and system
board.

1. Before you place the CPU on the heat sink, you must apply a thermal paste onto the
top of the heat sink. The thermal paste is usually supplied when you purchase the fan
with heat sink assembly. Do not spread the paste all over the surface. When you later
place the CPU on top of the heat sink, the compound will disperse evenly.
Some heat sinks come with a patch of pre-applied thermal paste. Do not apply thermal
paste if the fan with heat sink already has a patch of thermal paste on its underside.
Peel the strip that covers the paste before you place the CPU on top of the heat sink.
2. To insert the CPU into the CPU carrier, please first locate the gold triangular mark on
the CPU. The triangular mark must align with the triangular corner of the CPU carrier
shown on the photo. Without touching the pins, press the CPU onto the carrier until the
CPU is retained by the latches.
