MX680RD User’s Manual
1.5 Central Processing Unit (CPU)
This mainboard supports the Intel® LGA1700 socket Alder Lake S 12th generation Core™
i9, Core i7, Core i5, Core i3, Pentium, Celeron (65W max) processor.
• Your boxed Intel® LGA1700 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
LGA1700 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.
NOTES:
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. If you purchased a separate CPU heatsink and fan assembly. Make sure that you
applied 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 power cord from the grounded outlet first in order to
prevent damage to the system.
4. If you changed with different model of CPU with this mainboard, it is recommended
to clear the CMOS with the board, in order to prevent CPU information stored in
NVRAM not getting cleared properly.
