Server ECC RDIMM for heavy workloads

This 32 GB DDR4 2933 MHz module uses ECC RDIMM technology to detect and correct single-bit errors in real time. The registered design reduces electrical load on the memory controller for stable operation in multi-socket servers and workstations. It is built for administrators who need dependable capacity for virtualisation, databases or large datasets.

Standard voltage and registered buffering

Operating at 1.20 V the module follows the DDR4 standard voltage specification without elevated power draw. Registered buffering limits signal loading so the memory controller runs cooler under sustained throughput. No additional cooling or voltage tuning is required for normal server deployment.

Direct replacement for Samsung M393A4G43AB3-CVF

This unit matches the Samsung M393A4G43AB3-CVF specification exactly, providing a drop-in upgrade for systems qualified with that part number. The 2Rx8 organisation suits platforms that require dual-rank density per channel. Verify your system’s qualified vendor list before purchase if you need more than one rank per DIMM slot.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, and ensure the server BIOS recognises the registered ECC module at 2933 MHz.

What maintenance or replacement will this 32 GB 2Rx8 module need over time?

No routine maintenance is required; if a memory error occurs the module would be replaced under the lifetime warranty rather than serviced.

What limit appears first when this CL21 1.20 V kit runs sustained workloads?

The CAS 21 latency at 2933 MHz sets the response-time floor before thermal or voltage limits are reached.
