Capacity and platform fit

This 512GB kit contains eight 64GB DDR5 4800 CL40 ECC RDIMM modules built for Supermicro servers and workstations. Registered buffering and on-die ECC protect data integrity in multi-socket systems running continuous workloads. The 1.10V operating voltage matches the DDR5 baseline for these platforms.

Suitable builds and mismatched needs

IT teams deploying SuperMicro IoT SuperServer SYS-211SE-31DS, SYS-211SE-31AS or X31SEED-SF motherboards can install this kit directly. Buyers who need non-ECC memory, lower latency timings or desktop DIMM form factors should look at something else.

Deciding specification

The registered ECC RDIMM design is the single attribute that determines whether this kit works in your server. Consumer boards that accept only unbuffered non-ECC UDIMMs cannot use these modules.

Questions about this item

How do I install the 8×64GB DDR5 4800 RDIMMs in my Supermicro server and which slot order do I follow?

Power down the server, open the chassis, and insert each 288‑pin module into the DIMM slots specified in the Supermicro motherboard manual for 8‑DIMM population; the registered design requires correct channel order to initialise.

What maintenance or replacement will the 512GB DDR5 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no periodic maintenance is required; if a module fails, the lifetime replacement warranty covers a direct swap of the defective 64GB stick.

What is the first limit I will hit when running the 4800 CL40 2Rx4 kit at full load continuously?

The CAS latency of CL40 at DDR5‑4800 sets the baseline response time; sustained workloads will be bounded by this timing before thermal or voltage limits become a factor.
