256GB DDR4 3200 ECC RDIMM Kit

This kit provides 256GB of DDR4 3200 memory using two 128GB registered DIMMs. It is built for Thinkmate HDX-XN server and workstation platforms that require ECC registered modules. The modules run at 1.2V with a CL22 latency and a 4Rx4 organisation.

For Thinkmate HDX-XN Servers Only

This memory suits administrators upgrading compatible Thinkmate HDX-XN24 or HDX-XN12 systems that accept 4Rx4 registered ECC RDIMMs. It will not work in desktops, laptops, or consumer motherboards that require unbuffered non-ECC modules or a different pin-out.

4Rx4 Registered ECC Determines Compatibility

The 4Rx4 registered ECC layout is the single specification that decides fitment; only platforms qualified for this rank and buffer type will recognise the modules. Verify the server memory qualification list before purchase to ensure the 288-pin RDIMMs are supported.

Questions about this item

Will the CL22 latency hold steady when the 256GB kit runs at DDR4 3200 continuously?

The modules are rated CL22 at 3200 MT/s and tested under load, so the rated latency is maintained during sustained operation.

How much heat and power does the 1.2 V 4Rx4 registered kit produce in a 24/7 server?

At 1.20 V the two 128 GB RDIMMs draw modest power and run without a heat spreader; registered buffering keeps electrical load low for the memory controller.

Which Thinkmate servers must I already own for this 288-pin DDR4 RDIMM kit to work?

The kit is validated for the HDX-XN24-52S3, HDX-XN24-32S3, HDX-XN12-52S3 and HDX-XN12-32S3 models.
