Capacity and configuration

This is a 1.5TB DDR5 ECC RDIMM kit built from twelve 128GB modules. It is designed for the ThinkMate GPX-QH12-12E4-2GPU server platform where registered memory and error correction are required. The 4Rx4 organisation supports high-density population across all slots.

Thermals and power

Each module runs at 1.1V without a heat spreader, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping to keep power draw predictable during normal operation. The standard DDR5 4800 speed maintains typical voltage levels for this class of memory.

Sustained load behaviour

CL40 latency and PC5-38400 bandwidth are maintained across the full 1.5TB array during extended workloads. ECC circuitry continuously corrects single-bit errors to prevent data corruption in long-running compute tasks. The 288-pin registered interface ensures signal integrity when all twelve slots are populated under heavy utilisation.

Questions about this item

How do I install the 12x128GB DDR5 4800 ECC RDIMM kit in the THINKMATE GPX-QH12-12E4-2GPU server?

Power down, open the chassis, locate the 288-pin DDR5 slots, align each module notch, press firmly until clips lock, populate all 12 slots per the motherboard manual, then power on and verify 1.5TB in BIOS.

What maintenance or replacement will the 1.5TB DDR5 4800 ECC RDIMM kit need over time?

No routine maintenance is required; ECC corrects single-bit errors on the fly, and if a module fails the lifetime replacement warranty covers it, so you simply swap the faulty 128GB stick.

What limit appears first when the 12x128GB DDR5 4800 CL40 1.1V RDIMM kit runs sustained workloads?

The 4800 MT/s data rate and CL40 latency set the throughput ceiling, while the 1.1V operating voltage and registered 4Rx4 design keep thermals steady under continuous load.
