Installation order
Install DIMMs one by one in order of increasing memory size into slots in the order of DIMM#1, DIMM#2,
DIMM#3, and DIMM#4. However, if you want to run the server in 2Way Interleave mode, observe the
following when installing the DIMMs:
•
Install DIMMs in pairs
•
The two DIMMs installed together must be of the same specifications and memory size.
•
Install the pairs as DIMM#1 and DIMM#2, or DIMM#3 and DIMM#4 (the installation order between the
pairs does not matter.)
