•
For 1-CPU configuration
Install DIMM on at least all of CPU1_DIMM1 to DIMM3 slots.
•
For 2-CPU configuration
Install DIMM on at least all of CPU1_DIMM1 to DIMM3 and CPU2_DIMM1 to DIMM3 slots.
For effective use of the Cluster On Die feature, the recommended number of DIMMs to be installed is as follows:
•
For 1-CPU configuration
Install DIMM on CPU1_DIMM1 to DIMM4 slots.
Otherwise, install DIMM on CPU1_DIMM1 to DIMM8 slots.
•
For 2-CPU configuration
Install DIMM to CPU1_DIMM1 on DIMM4 and CPU2_DIMM1 to DIMM4 slots.
Otherwise, install DIMM on CPU1_DIMM1 to DIMM8 and CPU2_DIMM1 to DIMM8 slots.
