Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1.
Dual Channel mode cannot be enabled if only one memory module is installed.
2.
When enabling Dual Channel mode with two or four memory modules, it is recommended that memory
of the same capacity, brand, speed, and chips be used. For optimum performance, when enabling
Dual Channel mode with two memory modules, we recommend that you install them in the DDR4_A2
and DDR4_B2 sockets.
