User's Manual

The four memory sockets are divided into two channels and each channel has two memory sockets as following:
ChannelA:DDR4_A1,DDR4_A2
ChannelB:DDR4_B1,DDR4_B2
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

andDDR4_B2sockets.
