128 GB DDR4 ECC RDIMM kit

This NEMIX RAM kit supplies 128 GB across two 64 GB DDR4 3200 registered DIMMs. Each module runs at 1.2 V with CL22 latency and a 4Rx4 organisation. The 288-pin RDIMM form factor targets ThinkMate server platforms listed in the compatibility data.

ThinkMate server upgrades only

The memory is validated for ThinkMate HDX-XN24-52S3, HDX-XN24-32S3, HDX-XN12-52S3 and HDX-XN12-32S3 systems. It will not suit desktop motherboards that require unbuffered non-ECC DIMMs. Buyers needing consumer speeds or laptop SO-DIMMs should look elsewhere.

4Rx4 registered DDR4 organisation

Each 64 GB module uses a 4Rx4 rank structure that demands a server chipset capable of registered ECC operation. Confirm the host platform supports 4Rx4 RDIMM population rules before purchase.

Questions about this item

Will the 4Rx4 registered ECC modules need firmware updates or re-seating over time?

The modules are stress-tested before shipment and carry a lifetime replacement warranty; no firmware updates are required and re-seating is only needed if the server is moved.

What limits sustained throughput on these CL22 3200 MT/s RDIMMs?

The CL22 latency at DDR4-3200 sets the timing ceiling; the memory controller cannot push data faster than the rated speed allows.

How much heat and power do two 64 GB sticks draw at 1.2 V in a Thinkmate chassis all day?

Each module runs at 1.20 V with no heat spreader; total draw stays within standard DDR4 RDIMM limits and airflow from the server fans keeps temperatures in check.
