Central Processing Unit (CPU)
This mainboard supports the Intel® LGA1151 socket for Intel® Core™ i5/i3/Pentium Coffee Lake
processors in LGA-1151 package.
• Your boxed Intel® LGA1151 processor package should come with installation instructions for
the CPU, fan, heatsink, and the retention assembly.
• Upon purchase of the mainboard, make sure that the PnP cap is on the socket and the socket
pins are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket pins/mainboard components. BCM will shoulder the cost of
repair only, if the damage is shipment/ transit-related.
• Keep the PnP cap after installing the mainboard. BCM will process Return Merchandise
Authorization (RMA) requests only if the mainboard comes with the cap installed on the
LGA1151 socket.
• The product warranty does not cover damage to the socket pins resulting from incorrect CPU
installation/ removal, or misplacement/ loss/ incorrect removal of the PnP cap.
1. Overheating: Overheating will seriously damage the CPU and mainboard. Always
make sure the cooling fan can work properly to protect the CPU from overheating.
2. Make sure that you apply an even layer of thermal paste between the CPU and the
heatsink to enhance heat dissipation.
3. Replacing the CPU: While replacing the CPU, always turn off the ATX power suppply
or unplug the power supply’s powr cord from the grounded outlet first in order to
prevent damage to the system.
