Certified server memory

This 32 GB DDR4 RDIMM is built for Supermicro platforms that require registered ECC modules. It targets administrators upgrading or repairing enterprise servers and workstations where data integrity is mandatory.

Capacity and headroom

A single 32 GB module adds substantial headroom for virtualization, database caching and multi-user workloads. The dual-rank 2Rx4 organisation keeps signal loading low, but a system limited to one DIMM per channel will reach its maximum density with this part.

CL22 latency at 3200 MT/s

The module runs at CL22 with a standard 1.20 V supply, delivering 25 600 MB/s bandwidth per stick. Buyers needing tighter timings or higher frequencies must verify platform support before ordering.

Questions about this item

Will this 3200MHz RDIMM run with my existing DDR4 modules at a lower common speed?

The module operates at 3200MHz with CL22 latency and 1.20V; when mixed with slower DDR4 the system typically downclocks all modules to the lowest rated speed and loosest timings.

How can I verify the 32GB ECC Registered module is detected correctly after installation?

Check the BIOS or UEFI memory information screen — it should show 32GB, DDR4 3200, ECC Registered, 2Rx4 organisation and the Samsung M393A4K40EB3-CWE part number.

Does the single 288-pin RDIMM ship with any brackets, cables or a heatsink, or must I buy them separately?

The box contains only the 32GB DDR4 3200MHz 2Rx4 ECC Registered 288-pin RDIMM; no brackets, cables or additional heatsinks are included.
