Capacity and configuration

This kit provides 768GB of DDR5 server memory in six 128GB registered DIMMs. It is designed for enterprise servers and workstations that require high-density ECC modules for data integrity.

Thermals noise and power draw

The modules operate at 1.1V without heat spreaders, relying on system airflow for cooling. Registered buffering and ECC functionality add minimal overhead to the memory subsystem power budget.

Build integration

The 288-pin RDIMM form factor fits standard DDR5 server motherboards with registered memory support. Six populated slots leave no empty DIMM positions in a six-channel configuration, so capacity cannot be expanded without replacing modules.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules, and what step is commonly missed?

Align each module's key notch with the motherboard slot, press down firmly until both retention clips click, and follow the board manual's channel population order for 4Rx4 registered DIMMs.

What maintenance or replacement will the 6 x 128GB kit need over time?

No scheduled maintenance is required; if a module fails it is replaced individually, and the registered ECC design helps detect errors before they affect data integrity.

What limit appears first when the 4800 MHz CL40 memory runs under sustained load?

The 1.10 V operating voltage and CL40 latency define the thermal and timing envelope; sustained throughput is bounded by the DDR5 4800 (PC5-38400) specification.
