System memory
Overview
This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The figure illustrates the location of the DDR4 DIMM sockets:
Channel
Sockets
Channel A
DIMM_A1 & DIMM_A2
Channel B
DIMM_B1 & DIMM_B2
•
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.
•
According to Intel
®
CPU spec, DIMM voltage below 1.35V is recommended to protect
the CPU.
•
Due to Intel
®
chipset limitation, DDR4 2666MHz and higher memory modules will run
at max. 2666MHz on Intel
®
8th Gen. 6-core or higher processors.
•
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 (4 DIMMs).
