1.4 System memory
This motherboard comes with two Double Data Rate 4 (DDR4) Small Outline Dual Inline
Memory Module (SO-DIMM) sockets. The gure illustrates the location of the DDR4 DIMM
sockets:
DIMM_B1*
DIMM_A1*
Channel Sockets
Channel A DIMM_A1*
Channel B DIMM_B1*
• 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 conguration. 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 10
th
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.
• 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 efcient memory cooling system to support a full
memory load (2 DIMMs).
• Refer to www.asus.com for the latest Memory QVL (Qualied Vendors List).
