• DIMMs on channel A (DIMM1A and 2A) are paired with DIMMs on
channel B (DIMM1B and 2B) to enable two-way interleaving.
When only two DIMMs are being used, the population order must
be DIMM1A and DIMM1B to ensure dual-channel operating mode.
• For best performance and dual-channel interleave operation,
DIMM modules must be installed or removed in matched pairs,
following the slot sequence: DIMM1A and 1B first, then DIMM2A
and 2B.
• Observe the population sequence illustrated in the table below
when installing a memory module.
