2. DIMM slots
The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for
DDR5 (Double Data Rate 5) memory modules.
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 registered DDR5 DIMMs into the DIMM sockets.
• AMD Ryzen™ processors support ECC registered memory.
• 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.
