64GB DDR5 ECC RDIMM Kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for the ThinkMate GPX-QH12-12E4-2GPU GPU-optimised server and suits workloads that demand error-correcting memory in a registered configuration.

Compatibility Check

Verify that your motherboard accepts 288-pin DDR5 RDIMMs and supports registered ECC operation at 1.1V. The system must be able to populate four slots with 1Rx8 modules running at 4800 MT/s. Confirm the server's qualified vendor list includes this part number before ordering.

Thermals and Power

Modules operate at the standard DDR5 voltage of 1.1V and ship without heat spreaders. Registered buffering reduces electrical load on the memory controller, helping keep power draw steady during sustained GPU-accelerated workloads. Passive cooling relies on chassis airflow across the bare PCB.

Questions about this item

What comes in the box and is any extra hardware required?

The package contains four 16 GB DDR5 4800 CL40 ECC RDIMM modules totalling 64 GB; no additional cables, brackets or heat spreaders are needed for installation.

Which capacity kit should I choose for the Thinkmate GPX-QH12-12E4-2GPU?

This 64 GB kit (4 x 16 GB) matches the validated configuration for that server; select a different kit only if your workload demands more or fewer modules.

What does the 4800 MT/s rating mean once the memory is installed?

The modules will run at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, delivering the rated bandwidth and ECC protection on the supported platform.
