32GB DDR4 ECC LRDIMM for servers

This 32GB DDR4 module runs at 2400MHz with CL17 latency and 1.20V operation. It uses a Load Reduced DIMM design with 2Rx4 organisation and Samsung chipset. The 288-pin form factor fits server and workstation platforms that require registered ECC memory.

Load Reduced design limits standard DIMM slots

LRDIMM technology reduces electrical load on the memory bus so larger capacities can populate every slot. Standard unbuffered or registered DIMMs cannot mix with this module. The DDR4 2400 interface caps bandwidth at PC4-19200 regardless of faster CPU support. Systems must explicitly qualify LRDIMM population rules in their memory reference guide.

Replaces Samsung M386A4K40BB0-CRC4Q in qualified

This A-Tech unit is a compatible replacement for the Samsung part number listed. The upgrade is worthwhile when the platform's qualified vendor list includes this exact LRDIMM rank and speed. Buyers who need non-ECC memory or standard RDIMM registration cannot use this module.

Preguntas sobre este artículo

Should I choose this 32GB DDR4 2400MHz ECC LRDIMM module or a different capacity for my server upgrade?

This module provides 32GB in a single 2Rx4 LRDIMM. Select it when your server requires registered ECC memory at 2400MHz and has available 288-pin DDR4 slots supporting load-reduced DIMMs.

What does the 2400MHz PC4-19200 rating deliver once installed in a compatible server?

The module runs at 2400MHz with CL17 latency and 1.20V, providing 19200 MB/s peak bandwidth per stick while the ECC LRDIMM design reduces electrical load on the memory controller for stable operation.

How does the DDR4 288-pin LRDIMM interface limit performance compared to standard RDIMMs?

The 288-pin DDR4 LRDIMM uses a 2Rx4 organisation with a 1.2V supply. Its load-reduced buffer allows higher capacities per channel than standard RDIMMs, but the bus remains capped at the 2400MHz PC4-19200 data rate.
