1.3 Central Processing Unit (CPU)
This motherboard comes with a surface mount Intel® Socket LGA1200
designed for 10th Gen Intel®Core™, Pentium®Gold and Celeron®
Processors.
Unplug all power cables before installing the CPU.
• Ensure that you install the correct CPU designed for the LGA1200 socket only. DO
NOT install a CPU designed for LGA1150, LGA1151, LGA1155 and LGA1156 sockets
on the LGA1200 socket.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the
LGA1200 socket.
• The product warranty does not cover damage to the socket contacts resulting from
incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
cap.
• The CPU ts in only one correct orientation. DO NOT force the CPU into the socket to
prevent bending the connectors on the socket and damaging the CPU.

1.4 System memory
This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The gure illustrates the location of the DDR4 DIMM sockets:
Channel Sockets
Channel A DIMM_A1 & DIMM_A2*
Channel B DIMM_B1 & DIMM_B2*
DIMM_B1
DIMM_B2*
DIMM_A1
DIMM_A2*
• You may install varying memory sizes in Channel A and Channel B. The system
maps the total size of the lower-sized channel for the dual-channel conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
• Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.
• For 10th Gen Intel®processors, only Core™ i9/i7 CPUs support
2933/2800/2666/2400/2133 natively, others will run at the maximum transfer rate of
DDR4 2666MHz.
• A DDR4 memory module is notched differently from a DDR, DDR2, or DDR3 module.
DO NOT install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.
• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value.
• For system stability, use a more efcient memory cooling system to support a full
memory load.
• Refer to www.asus.com for the latest Memory QVL (Qualied Vendors List).
