SuperMicro DDR5 4800 ECC RDIMM Kit

This NEMIX RAM memory kit provides 256GB of DDR5 4800 registered ECC memory in a matched pair of 128GB modules. It is built for SuperMicro SuperWorkstation SYS-551A-T and Super X13SWA-TF systems that require registered DIMMs. The modules operate at 1.1V with a CAS latency of CL40 and use a 4Rx4 organisation. They are validated for stability in demanding server and workstation workloads.

Suited for registered DDR5 platforms needing high

This kit suits IT professionals upgrading compatible SuperMicro workstations or servers where registered ECC memory is mandatory. Builders using consumer motherboards, laptops, or any platform that accepts only unbuffered non-ECC UDIMMs cannot use these modules. Systems limited to lower maximum capacities or different pin counts should look elsewhere.

Registered ECC with 4Rx4 organisation at 4800 MT/s

The decisive specification is the registered ECC RDIMM format combined with a 4Rx4 rank structure running at DDR5 4800. Only motherboards explicitly qualified for registered DDR5 ECC memory with this rank configuration will support the kit. Verify the system memory qualification list before purchase.

Preguntas sobre este artículo

Will the 288-pin DDR5 RDIMM modules fit the memory slots on the Supermicro SuperWorkstation SYS-551A-T?

Yes, these 288-pin DDR5 RDIMM modules are built to the standard DDR5 form factor required by the Supermicro SuperWorkstation SYS-551A-T.

What is the correct installation sequence for the two 128GB modules in the Supermicro X13SWA-TF motherboard?

Install each 128GB module into the designated DDR5 slots following the motherboard manual's population order; the registered design requires full seating until the retention clips lock.

How often should the 256GB DDR5 4800 ECC RDIMM kit be replaced in a continuously running server?

DDR5 ECC RDIMM modules have no scheduled replacement interval; they remain in service until a memory test reports correctable or uncorrectable errors.
