64GB DDR4 3200 ECC RDIMM kit

This 64GB kit contains four 16GB DDR4 3200 ECC RDIMM modules rated at PC4-25600 with CL22 timings and 1.2V operation. The registered design and 2Rx8 organisation target Thinkmate HDX-XN24 and HDX-XN12 server platforms that require registered ECC memory.

Registered ECC with major OEM chips

Each module uses Samsung, Micron or Hynix components and ships without heat spreaders to fit dense server DIMM slots. The registered buffer and on-die ECC correct single-bit errors and reduce electrical load on the memory controller, supporting stable operation under sustained workloads.

Suits Thinkmate HDX-XN servers needing registered

Builders upgrading compatible Thinkmate HDX-XN24-52S3, HDX-XN24-32S3, HDX-XN12-52S3 or HDX-XN12-32S3 systems can add this kit directly. Buyers who need unbuffered UDIMMs, non-ECC memory, speeds above 3200MT/s, or capacities beyond 64GB should look at other configurations.

Questions about this item

Will the 1.2V DDR4 modules need any firmware updates or re-training after the server runs for several months?

No firmware updates or re-training are required; the registered ECC RDIMMs operate at the rated 1.2V and CL22 timings for the life of the installation.

What is the first limit reached when all four 16GB sticks run at 3200 MT/s under continuous load?

The CL22 CAS latency at 3200 MT/s is the primary timing boundary; the registered buffer and ECC logic maintain stability up to that rated speed.

How much extra heat or fan noise should I expect from the 64GB kit running 24/7 in a ThinkMate chassis?

The modules have no heat spreader and draw only 1.2V, so thermal output is minimal and typically handled by existing server airflow without added noise.
