32 GB DDR4 ECC RDIMM for Supermicro servers

This 32 GB DDR4 2400 CL17 registered DIMM is built for Supermicro motherboards including the A2SD1-3750F, A2SD1-3955F, X10DRFR-N, X10DRFR-NT and X10DRH-CT. It operates at 1.2 V with a 2Rx4 organisation and very low profile height. The module delivers error-correcting code protection for workloads that cannot tolerate silent data corruption.

Replaces Supermicro MEMDR432L part numbers

The module is a direct replacement for Supermicro part numbers MEMDR432LCL02ER24, MEMDR432LCV01ER24, MEMDR432LCV02ER24, MEMDR432LHL01ER24, MEMDR432LHL02ER24, MEMDR432LSL01ER24, MEMDR432LSL02ER24 and MEMDR432LSV01ER. The upgrade is worth it when existing capacity limits virtualisation density or when ECC registered memory is required for data integrity in 24/7 operation.

Suits administrators extending supported

Buyers who need registered ECC memory for the listed Supermicro boards will find the correct voltage, latency and rank configuration here. Builders using standard desktop motherboards, unbuffered DIMM slots or load-reduced memory architectures should look elsewhere because this module is electrically incompatible with those platforms.

Questions about this item

Will the 288-pin VLP form factor fit inside my 1U server chassis?

The module uses a very-low-profile design that matches the 288-pin DDR4 slot height, so it clears standard 1U heatsink clearance.

What is the correct seating procedure for this registered ECC DIMM?

Align the off-centre notch with the slot key, press straight down until both ejector tabs click, then verify the module sits flush — partial seating causes boot failure.

When should I plan to replace this 32 GB module?

DDR4 ECC RDIMMs have no wear-out cycle; replace only if memory diagnostics report correctable errors rising above threshold or a DIMM fails POST.
