When Replacing Faulty FB-DIMMs
Within each branch, ensure that the replacement FB-DIMM has the same part
number as the FB-DIMM you are removing. If you are unable to obtain an FB-DIMM
with the same part number, you might need to replace all FB-DIMMs in the branch
to ensure that they all have the same part number.
The following table lists the supported FB-DIMMs and part numbers.
2.2.1.1 DIMM Installation Rules
Caution – The following FB-DIMM rules must be followed. The server module
might not operate correctly if the FB-DIMM rules are not followed. Always use
DIMMs that have been qualified by Sun.

The following configurations are supported in the Sun Blade T6320 server module:
