The memory-channel configuration table below shows the relationship between the processors, memory
controllers, memory channels, and memory module slot numbers.

DIMMs with different capacity
√
Single-rank DIMM and dual-rank DIMM
√
DIMMs manufactured by different vendors
√
Notes:
• When installing DIMMs with different capacity, install the DIMM with the highest capacity first following the
population sequence.
• For optimal performance, it is recommended to install DIMMs with identical capacity and rank in the same channel
of the two processors.
Memory module installation order
Notes: In the following tables:
• S1–S24 indicate DIMM slots 1–24.
• 1–24 indicate the installation order.
For example, when 12 DIMMs are installed for two processors, the installation order is slot 7, 19, 6, 18, 9, 21,
4, 16, 8, 20, 5, 17.
