Overview of Components
DIMM Slots
Important
Always insert memory modules in the DIMMA1 slot first.
Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
Based on CPU specification, the Memory DIMM voltage below 1.35V is suggested to
protect the CPU.
To ensure system stability for Dual channel mode, memory modules must be of the
same type, number and density.
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.
It is recommended to use a more efficient memory cooling system for full DIMMs
installation or overclocking.
The stability and compatibility of installed memory module depend on installed CPU
and devices when overclocking.
Please refer www.msi.com for more information on compatible memory.
