DIMM installation order

1.8.2
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.
If you want to run the server in Dual Channel mode, observe the following when installing the DIMMs:
• Install them 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.)
