Capacity and Compatibility

This kit provides 256GB of DDR4 memory across sixteen 16GB registered DIMMs. It is built for ThinkMate HDX high-density servers that require ECC RDIMM modules. The 2Rx8 organisation and CL22 timing match the platform specifications listed by the supplier.

DDR4 3200 Registered Limits

The modules run at DDR4 3200 (PC4-25600) with a CAS latency of 22 and operate at 1.20V. Registered buffering and ECC are mandatory for the target servers; unbuffered or non-ECC DIMMs will not function in these slots. The 288-pin RDIMM form factor is the only type accepted by the compatible ThinkMate models.

Build and Daily Use

Major OEM chips from Samsung, Micron or Hynix are assembled without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM keying prevents accidental insertion into consumer UDIMM sockets. Sixteen modules fill a high-density configuration, so installers must populate all channels exactly as the system manual directs.

Questions about this item

Should I pick the 16 x 16 GB kit or a smaller set for my ThinkMate server?

The 256 GB kit fills 16 slots with 16 GB modules, so choose it only if your HDX-QT24 or HDX-QN24 chassis has enough free DIMM sockets and your workload needs that total capacity.

What does the 3200 MT/s rating deliver once the modules are installed?

The memory runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V, giving the rated throughput and timing the platform negotiates at boot.

How does the 288-pin RDIMM interface limit what I can do?

The registered 288-pin DDR4 RDIMM form factor fits only server boards that accept registered ECC modules; it will not work in unbuffered desktop or laptop slots.
