System Memory - Asus H310M2 R2.0/FPT Manual

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:

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.
DDR4 2666MHz and higher memory modules will run at max. 2666MHz on Intel
Generation 6-core or higher processors.
Memory modules with memory frequency higher than 2133 MHz and its
corresponding timing or the loaded X.M.P. Profile is not the JEDEC memory standard.
The stability and compatibility of these memory modules depend on the CPU's
capabilities and other installed devices.
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).
Refer to www.asus.com for the latest Memory QVL (Qualified Vendors List).
If you want to use one/two single-sided/double-sided memory module(s), install them
into the grey DIMM sockets (DIMM_A2, DIMM_B2).
Due to Intel chipset limitations, this motherboard can only support single-sided
®
memory modules when four modules are installed and they will run at the maximum
transfer rate of DDR4 1866Mhz
