768GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit supplies 768GB of DDR5 4800 registered ECC memory across twelve 64GB modules. It is built for Thinkmate HDX-XH24-52S4 high-density servers that require 2Rx4 organisation and 1.10V operation. The modules use major OEM Samsung, Micron or Hynix chips and carry a CL40 latency rating.

Who This Suits and Who It Does Not

IT teams upgrading compatible Thinkmate platforms to the maximum supported capacity will find a matched, stress-tested set. Buyers who need non-ECC unbuffered DIMMs, lower capacities or different form factors must select another product.

Deciding Specification — 2Rx4 Registered ECC

The 2Rx4 registered ECC organisation is the single attribute that determines whether this kit works in the target server. Confirm the motherboard requires registered ECC RDIMMs with this rank configuration before purchasing.

Questions about this item

Will the 12-module 768GB kit work alongside the 64GB RDIMMs already installed in my THINKMATE HDX-XH24-52S4 server?

The kit provides twelve 64GB DDR5 4800 CL40 2Rx4 1.1V ECC registered DIMMs. Mixing ranks or speeds can prevent the server from completing memory training, so populate all slots with identical modules for guaranteed operation.

How do I confirm the 4800 MT/s CL40 registered ECC modules are running at their rated speed and timings after installation?

Enter the server BIOS or UEFI and verify the memory frequency reads 4800 MT/s with CAS latency 40. ECC status should show enabled, and the registered DIMM type must be reported for each of the twelve 288-pin slots.

Does the package contain only the twelve 64GB DDR5 RDIMMs, or are heat spreaders, tools or cables included?

The box holds the 768GB kit — twelve 64GB DDR5 4800 PC5-38400 2Rx4 1.1V CL40 288-pin ECC registered DIMMs. No heat spreaders, installation tools or extra cables are supplied.
