Capacity and fit

This 768 GB kit contains twelve 64 GB DDR5 registered DIMMs built for ThinkMate GPX-XH20-28S4-8HGX GPU-optimised servers. IT teams upgrading those platforms receive a matched set that meets the system's ECC and registered requirements.

Thermals and power

Each module operates at 1.10 V with a CL40 latency and no heat spreader. The low voltage helps keep power draw modest while the bare-DIMM design relies on the server's directed airflow for cooling.

Sustained load behaviour

Modules are stress-tested under load before shipping to verify stability during extended compute tasks. Registered signalling and on-die ECC maintain data integrity across all twelve slots during continuous operation.

Questions sur cet article

How do I install the 12 DDR5 RDIMM modules into the ThinkMate server, and which step is most often missed?

Power down the server, open the chassis, locate the 288-pin DDR5 slots, align each module's notch with the slot key, press firmly until both latches click, then verify all 12 modules are fully seated before closing the case — the step most often missed is confirming every latch has engaged on both sides.

What maintenance or replacement will this 768GB ECC registered kit need over its service life?

The modules have no heat spreaders and no moving parts, so routine maintenance is limited to keeping server airflow paths clean; replacement is only required if a module fails ECC correction or the server's memory test reports uncorrectable errors.

What limit appears first when this 4800 CL40 2Rx4 kit runs sustained workloads on the ThinkMate GPU-optimised server?

The primary limit is the DDR5 4800 MT/s bandwidth ceiling combined with CL40 latency; under continuous heavy load the memory controller will hit throughput saturation before thermal throttling becomes a factor at the standard 1.1 V operating voltage.
