System Memory - Asus B450M-A/CSM User Manual

System memory

Overview
This motherboard comes with two Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The figure illustrates the location of the DDR4 DIMM sockets:
• 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 configuration. 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 system stability, use a more efficient memory cooling system to support a full
memory load (2 DIMMs).
• Refer to www.asus.com for the latest Memory QVL (Qualified Vendors List)
