5.4.1.2 Memory Subsystem Architecture
The 2488 V5 provides 32 memory slots. Each processor integrates six memory
channels.
Install the memory modules in the primary memory channels first. If the primary
memory channel is not populated, the memory modules in secondary memory
channels cannot be used.
