Capacity and Compatibility

This 256GB kit contains four 64GB DDR5 ECC RDIMM modules built for SuperMicro Hyper SuperServer systems including the SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R. It targets IT professionals who need registered, error-correcting memory for mission-critical server and workstation workloads.

Registered ECC at DDR5 4800

Each module runs at 4800MT/s (PC5-38400) with a CAS latency of CL40, 2Rx4 organisation and a 1.1V operating voltage. The registered buffer and on-die ECC protect data integrity under sustained load, making this specification the decisive factor for compatibility with the listed SuperMicro platforms.

288-pin DDR5 RDIMM form factor

The kit installs into standard 288-pin DDR5 RDIMM slots and requires a motherboard that supports registered ECC memory at the rated speed and voltage. It does not suit consumer desktop boards, unbuffered DIMM slots or systems that cannot address 64GB per module. Buyers needing non-ECC, lower-capacity or higher-speed modules should look elsewhere.

Questions sur cet article

What does the 4800 MT/s speed mean once the four 64 GB DIMMs are installed in a SuperMicro server?

The kit runs at DDR5 4800 with CL40 latency at 1.1 V, delivering the rated transfer rate across all four modules when the platform supports that speed.

How does the 288-pin DDR5 RDIMM interface and PC5-38400 rating limit real-world performance?

The registered 288-pin DDR5 form factor and PC5-38400 designation set the electrical and mechanical interface; the memory controller in the SuperMicro system determines the maximum usable throughput.

What physical space and slot arrangement do the four 2Rx4 modules need to fit in the SYS-121H-TNR, SYS-221H-TNR or SYS-221H-TN24R?

Each module is a standard 288-pin DDR5 RDIMM without a heat spreader; the four 64 GB sticks occupy four DIMM slots and require the server's memory population rules to be followed.
