DIMM slots
The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for
DDR5 (Double Data Rate 5) memory modules.
CAUTION! 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.

Memory configurations
You may install ECC or Non-ECC DDR5 DIMMs into the DIMM sockets.
NOTE:
• 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.
NOTE: DRAM installation detection function: The DRAM LED will detect if the memory modules
have been installed in the recommended memory configuration slots as well as if the memory
modules have been properly installed and seated in the memory slots once the motherboard is
connected to a power supply. After the motherboard has been powered on, the DRAM LED will
return to the original error checking procedure, regardless of the LED status prior to powering on.
