FAQ – Engineering & Procurement Perspective

1. When should LRDIMM be selected over RDIMM?
LRDIMM includes a data buffer in addition to a register, reducing electrical load on the memory controller. It is preferred in high-capacity server configurations where maximum density per channel is required.

2. Are RDIMM and LRDIMM interchangeable?
No. RDIMM and LRDIMM cannot be mixed within the same memory channel. Platform documentation should be reviewed before configuration planning.

3. What should data center procurement verify before deployment?
Confirm CPU support for DDR5 RDIMM or LRDIMM, validated speed grade, ECC compatibility and 3DPC capability. Maintaining consistent part numbers simplifies lifecycle management and reduces integration risk.
