Compatible SuperMicro server memory

This 64GB DDR4 LRDIMM is built for SuperMicro systems that require registered ECC memory. It operates at 2400MT/s with a CL17 latency and a 1.2V supply. The module uses a 4Rx4 organisation and a 288-pin form factor.

Load-reduced design for thermal efficiency

The load-reduced architecture reduces electrical loading on the memory bus, which helps maintain lower power draw per module during normal operation. ECC circuitry corrects single-bit errors without adding measurable latency. No heat spreader is fitted, relying on chassis airflow for cooling.

Sustained workload stability

All modules are stress tested under load before shipping to verify reliability in continuous server duties. The 1.2V operating voltage keeps thermal output consistent during extended runtime. This single 64GB stick suits configurations that populate every slot with maximum capacity.

Questions about this item

How do I install this 288-pin DDR4 LRDIMM in a SuperMicro server, and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that the 64GB module registers at 2400MT/s with ECC active — the step most often missed is confirming the memory mode supports load-reduced DIMMs.

What maintenance or replacement will this ECC LRDIMM need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts. Replace only if ECC logs report uncorrectable errors or the system fails POST with this DIMM seated — NEMIX RAM provides a lifetime replacement warranty for such cases.

What limit appears first when this 4Rx4 1.2V module runs sustained workloads?

The 4Rx4 organisation places the highest electrical load on the memory controller, so the practical ceiling is the maximum number of load-reduced ranks your specific SuperMicro platform supports per channel — exceeding that prevents the system from booting.
