128GB DDR5 ECC RDIMM for servers

This 128GB DDR5 6400MHz registered DIMM provides error-correcting memory for server and workstation platforms. The single module uses a 2Rx4 organisation and operates at the standard 1.10V. It is built as a compatible replacement for IBM-Lenovo part numbers 4X77A90993, 4X77A93529 and 03NA217. Systems needing ECC RDIMM capacity can use this module to expand memory.

Thermals noise and power draw

The module runs at the DDR5 standard voltage of 1.10V without a heat spreader. Registered buffering and ECC functionality add minimal overhead to power consumption during normal operation. Passive cooling relies on system airflow across the bare PCB. Acoustic output is silent as the component has no moving parts.

128GB single module capacity

This kit contains one 128GB DDR5 6400MHz RDIMM with CAS latency 32 and 2Rx4 rank configuration. The 288-pin form factor fits DDR5 RDIMM slots in compatible server and workstation boards. Buyers who need multiple matched modules or a different total capacity should verify their platform requirements before ordering.

Questions sur cet article

How do I install the 288-pin DDR5 RDIMM and which step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify the 1.10V setting in BIOS for DDR5 6400 operation.

What maintenance or replacement will the 128GB 2Rx4 ECC module need over time?

No routine maintenance is required; ECC corrects single-bit errors automatically, and the module should only be replaced if the system logs uncorrectable memory errors.

What limit appears first when the RDIMM runs sustained workloads at 6400MHz?

The registered buffer and 1.10V DDR5 voltage ceiling constrain maximum stable throughput before thermal or signal-integrity limits are reached.
