1.3 CPU installation

Unplug all power cables before installing the CPU.

• The AM5 socket has a different pinout design. Ensure that you use a CPU designed

for the AM5 socket. The CPU fits 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.

• ASUS will not cover damages resulting from incorrect CPU installation/removal,

incorrect CPU orientation/placement, or other damages resulting from negligence by

the user.

Chapter 1: Product Introduction

Apply the Thermal Interface Material to the CPU cooling system and CPU before you install

the cooling system, if necessary.

1.4 DIMM installation

A DDR5 memory module is notched differently from a DDR, DDR2, DDR3, or DDR4

module. DO NOT install a DDR, DDR2, DDR3, or DDR4 memory module to the DDR5

slot.

The figure illustrates the location of the DDR5 DIMM sockets

Recommended memory congurations

You may install Non-ECC DDR5 DIMMs into the DIMM sockets.

• You may install varying memory sizes in the DIMM channels. The system maps the

total size of the lower-sized channel for the dual-channel configuration. Any excess

memory from the higher-sized channel is then mapped for single-channel operation.

• 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 efficient memory cooling system to support a full

memory load or overclocking condition.

• Always install the DIMMS with the same CAS Latency. For an optimum compatibility,

we recommend that you install memory modules of the same version or data code

(D/C) from the same vendor. Check with the vendor to get the correct memory

modules.

• Visit the ASUS website for the latest QVL.
