Important
y Always insert memory modules in the DIMMA2 slot first.
y Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
y Based on processor specification, the Memory DIMM voltage below 1.35V is
suggested to protect the processor.
y Some memory modules may operate at a lower frequency than the marked value
when overclocking due to the memory frequency operates dependent on its Serial
Presence Detect (SPD). Go to BIOS and find the DRAM Frequency! to set the memory
frequency if you want to operate the memory at the marked or at a higher frequency.
y It is recommended to use a more efficient memory cooling system for full DIMMs
installation or overclocking.
y The stability and compatibility of installed memory module depend on installed CPU
and devices when overclocking.
y Due to AM4 processor/memory controller official specification limitation, the
frequency of memory modules may operate lower than the marked value under the
default state. Please refer www.msi.com for more information on compatible memory.
