NEMIX 32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 4800 module is a registered ECC RDIMM built for Samsung servers and workstations. It runs at 1.10V with CL40 latency and uses a 2Rx8 organisation on a 288-pin form factor. The part is validated for compatibility with Samsung M321R4GA3BB0?CQK systems.

Who this suits and who should look elsewhere

IT teams expanding memory in compatible Samsung platforms will find the registered ECC design meets stability requirements for mission-critical workloads. Builders needing unbuffered UDIMM modules for consumer motherboards or laptops cannot use this registered RDIMM. Systems that do not support ECC registered memory must choose a different memory type.

The specification that decides fit

The registered ECC RDIMM architecture is the single attribute that determines whether this module will function in a given platform. Only motherboards and servers explicitly qualified for DDR5 registered ECC memory can accept this 288-pin 2Rx8 module.

Questions about this item

How do I install this 288-pin DDR5 RDIMM and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC and registered mode are active for the 32GB capacity.

What maintenance or replacement will this ECC RDIMM need over time?

No scheduled maintenance is required; the module has no heat spreader and operates at 1.1V, so replacement is only necessary if a memory diagnostic reports uncorrectable errors or the server no longer recognises the 32GB capacity.

What limit appears first when this CL40 module runs sustained workloads?

The CAS latency of CL40 at 4800 MT/s sets the timing boundary; under continuous load the memory controller will throttle before the 1.1V supply or the 2Rx8 organisation becomes a bottleneck.
