DIMM population guidelines

The following rules apply when adding DIMMs to the memory boards.
• DIMMs must be populated beginning with memory board A,
DIMM slots A1 and A2.
• All DIMM slots must be populated with either a DIMM or a DIMM
thermal blank.
Important: DIMM thermal blanks must be installed to empty
DIMM slots to ensure proper system thermal performance.
