System-Specific DDR5 Kit

This 128GB kit contains four 32GB DDR5 4800 CL40 registered ECC RDIMMs built for the Thinkmate GPX-QH12-12E4-2GPU GPU-optimised server. It targets administrators who need maximum registered capacity in that exact platform.

Platform Integration

Each module is a 288-pin DDR5 RDIMM with 2Rx8 organisation and on-die ECC, designed to populate the server’s registered memory slots. The kit frees the builder from mixing speeds or ranks by providing a matched four-module set validated for the target system.

Thermals and Power

Modules run at 1.10V without heat spreaders, relying on the server’s directed airflow for cooling. Registered buffering and ECC add minimal overhead while maintaining signal integrity under sustained GPU-compute workloads.

Questions about this item

What is the CAS latency of the DDR5 4800 modules under sustained workloads?

The modules run at CL40 latency, which is the rated timing for DDR5 4800 operation on the ThinkMate GPX-QH12-12E4-2GPU server.

How much power do the four registered DIMMs draw at 1.1 V during continuous operation?

Each DIMM operates at 1.10 V; the registered design and ECC circuitry add modest overhead compared with unbuffered modules, but total draw stays within standard DDR5 RDIMM limits for this density.

Which server platform must already be installed for this 128 GB kit to function?

The kit is validated for the ThinkMate GPX-QH12-12E4-2GPU GPU-optimised server; the motherboard must provide 288-pin DDR5 RDIMM slots and support registered ECC memory.
