Purpose-built server memory kit

This 512 GB kit contains four 128 GB DDR5 RDIMM modules rated at 4800 MT/s with CL40 latency. It is designed for IT professionals and system integrators who need ECC registered memory validated for Thinkmate HDX-XH24-52S4 high-density servers.

Build integration requirements

Each module uses the standard 288-pin DDR5 RDIMM form factor and operates at 1.10 V. The 4Rx4 organisation and registered buffer reduce electrical load on the memory controller, freeing motherboard slots for maximum capacity in compatible Thinkmate platforms.

Ideal for capacity-focused deployments

Suited for administrators expanding memory in supported Thinkmate servers where registered ECC RDIMMs are required. Not suited for systems that accept only unbuffered UDIMMs, platforms limited to lower-density modules, or workloads demanding higher memory speeds than 4800 MT/s.

Questions about this item

How many ranks does the 4Rx4 organisation put on the memory controller with all four modules installed?

Each module is 4Rx4, so the four-module kit presents sixteen ranks to the controller.

What is the operating voltage and registered design impact on heat and power draw during continuous operation?

The kit runs at 1.10 V with registered buffering, reducing electrical load per pin and keeping power draw and thermals lower than unbuffered equivalents.

Which server platform is required for this 512 GB DDR5 4800 ECC RDIMM kit to function?

The memory is validated for the ThinkMate HDX-XH24-52S4 high-density server; the motherboard must support DDR5 4800 registered ECC RDIMMs.
