128GB DDR5 ECC RDIMM Kit

This kit provides 128GB of DDR5 memory across four 32GB registered DIMMs. It is built for the SuperMicro SYS-221HE series of IoT SuperServers. The modules add error-correcting capacity for virtualisation hosts, database nodes and other workloads that require data integrity.

DDR5 4800 CL40 Registered Limits

The modules run at DDR5 4800 with a CAS latency of CL40 at 1.1V. Registered signalling and ECC add command and address buffering plus single-bit error correction, which increases latency versus unbuffered memory. The 1Rx4 organisation caps rank-level parallelism on each channel.

Tool-Less DIMM Installation

Each 288-pin RDIMM seats vertically in the server’s memory slots; no tools are required beyond opening the chassis. Alignment keys prevent backward insertion. The main risk is mixing registered ECC modules with unbuffered or non-ECC DIMMs, which the platform will not accept.

Questions sur cet article

Should I choose the 128GB kit or look for a smaller capacity?

The kit provides 128GB total across four 32GB modules, filling four DDR5 RDIMM slots in the SuperMicro SYS-221HE.

What does the 4800MHz speed actually deliver in this server?

It runs at DDR5 4800 (PC5-38400) with CL40 latency, giving the maximum rated bandwidth the platform supports for registered ECC memory.

Does the 288-pin RDIMM interface limit how fast the memory can run?

The 288-pin DDR5 RDIMM form factor is the registered ECC standard for this server; the 4800MHz rating is the ceiling defined by the platform and module design.
