128GB DDR5 4800 ECC RDIMM for ThinkMate

This registered DDR5 module delivers 128GB of error-correcting memory at 4800 MT/s. It targets administrators upgrading ThinkMate GPX-XH20-28S4-8HGX GPU-optimised servers. The 4Rx4 organisation and CL40 latency suit high-density configurations.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous compute or AI workloads. The 1.1V operating voltage helps limit thermal output when all ranks are active. Modules are stress-tested under load before shipping.

Installation notes

The 288-pin DDR5 RDIMM fits keyed server DIMM slots; alignment notch prevents reverse insertion. Population rules depend on the server's memory-controller topology, so consult the platform manual. No heat spreader is present, so airflow across the PCB must be adequate.

Questions about this item

How much power does this 1.1V DDR5 4800 ECC RDIMM draw when the server runs continuously?

The module operates at 1.10V; DDR5 RDIMM power draw varies with workload and motherboard voltage regulation, so sustained consumption depends on your platform's memory controller and BIOS settings.

What motherboard slot and chipset support are required to install this 288-pin 4Rx4 registered DIMM?

It needs a DDR5 RDIMM slot with registered ECC support; the ThinkMate GPX-XH20-28S4-8HGX platform is validated, and other boards must explicitly list DDR5 4800 4Rx4 RDIMM compatibility.

Can I mix this 128GB 4Rx4 CL40 module with smaller DDR5 ECC RDIMMs already in my ThinkMate server?

Mixing ranks and capacities is platform-dependent; the GPX-XH20-28S4-8HGX memory population rules dictate which slots accept 4Rx4 modules alongside 1Rx4 or 2Rx4 DIMMs, so consult the system manual before adding.
