Memory module installation recommendation
⚠
Important
∙ Always insert memory modules in the DIMMB1 slot first.
∙ To ensure system stability for Dual channel mode, memory modules must be of the
same type, number and density.
∙ Based on processor specification, the Memory DIMM voltage below 1.35V is
suggested to protect the processor.
∙ Due to AM4 CPU/ memory controller official specification limitation, the frequency
of memory modules may operate lower than the marked value under the default
state.
∙ Please refer to www.msi.com for more information on compatible memory.
