DIMM Slots
Please install the memory module into the DIMM slot as shown below.
 Important
 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
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 www.msi.com for more information on compatible memory.
PCI_E1~3: PCIe Expansion Slots
 Important
 y
When adding or removing expansion cards, always turn off the power supply and 
unplug the power supply power cable from the power outlet. Read the expansion 
cards documentation to check for any necessary additional hardware or software 
changes.
 y
If you install a large and heavy graphics card, you need to use a tool such as MSI 
Gaming Series Graphics Card Bolster to support its weight to prevent deformation 
of the slot.
