DIMM 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.

If you want to run the server in 2Way Interleave 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.)
