Important If the number of DIMMs mounted is 9, 10, 11, 13, 14, 15, 17, 18, 19, 20, 21, 22,
or 23, Information Message 510 is displayed in the "Unbalanced, not
recommended" state during POST. This does not require any action.
510 - The installed number of DIMMs on one or more processors results in
an unbalanced memory configuration across memory controllers. This may
result in non-optimal memory
- Notice for the combination of DIMM
When more than one kinds of DIMM is combined, install them in the order from the following list to the installation
order on the above table.
(High priority) N8102-724 > N8102-723 > N8102-722 > N8102-721 > N8102-720 (Low priority)
DIMMs cannot be mixed within the server depending on the combination. They can be mixed only in the
following combinations.
