32GB DDR4 2400MHz ECC LRDIMM

This 32GB DDR4 2400MHz ECC LRDIMM module delivers 32GB of registered server memory in a single 288-pin DIMM. It operates at PC4-19200 speed with CL17 latency and 1.20V standard voltage. The 4Rx4 load-reduced design targets enterprise servers and workstations that require high-capacity, error-correcting memory.

Replaces Samsung M386A4G40DM1-CRC

This module serves as a compatible replacement for Samsung M386A4G40DM1-CRC and M386A4G40EM2-CRC part numbers. The upgrade is worth it when your system supports DDR4 LRDIMM topology and needs maximum density per slot. Verify your platform's qualified vendor list before installation to ensure proper operation.

Suits servers needing high-density ECC LRDIMM

This memory suits administrators expanding capacity in compatible DDR4 LRDIMM platforms. It is not for systems limited to standard RDIMM or UDIMM form factors. Buyers who need non-ECC memory, different voltage requirements, or higher frequency modules should look at alternative configurations.

Questions about this item

Will this 288-pin LRDIMM fit my server's DDR4 memory slots?

Yes, the module uses the standard DDR4 288-pin DIMM form factor and requires a motherboard slot that supports Load Reduced DIMMs at 1.2V.

What is the correct way to seat this 4Rx4 module, and what step do people often miss?

Align the notch with the slot key, press firmly until both side clips click shut, then verify the system recognises the full 32GB capacity and ECC function in BIOS.

How do I know when this ECC LRDIMM should be replaced?

Replace the module if the system logs uncorrectable ECC errors, fails memory diagnostics, or becomes unstable under load despite passing initial tests.
