Remove the following reusable components from the motherboard and install

DDR4 DIMMs
See “Identify and Remove a Faulty DIMM” on page 81 and “Install a
DIMM” on page 84.
Note - Install the DDR4 DIMMs only in the slots (connectors) from which they were
removed. Performing a one-to-one replacement of DIMMs significantly reduces the

DIMMs in the same slots, server performance might be reduced and some DIMMs might
not be used.
