128GB DDR5 ECC RDIMM kit

This kit provides 128GB of DDR5 4800 registered ECC memory in eight 16GB modules. It is built for Dell PowerEdge R6625 rack servers and other platforms that require 288-pin RDIMMs with 1Rx8 organisation.

Verify RDIMM slots and DDR5 support

Before ordering, confirm that your server motherboard accepts 288-pin DDR5 RDIMMs and can populate eight slots at 1.10V. Registered ECC modules will not work in consumer boards that only support unbuffered memory.

Thermals noise and power

The modules run at 1.10V without heat spreaders, relying on server chassis airflow for cooling. Registered DDR5 at this voltage typically draws modest power and produces no audible noise in a properly ventilated rack environment.

Questions about this item

Does the 128GB kit ship as eight separate 16GB modules or do I need to buy extra sticks?

The kit contains eight 16GB RDIMM modules for a total of 128GB; nothing else is required to reach that capacity.

Should I pick the CL40 4800MHz version or a different speed grade for my Dell PowerEdge R6625?

This CL40 DDR5 4800 kit is validated for the R6625; choose it when your server specification calls for PC5 38400 registered ECC memory.

What does the PC5 38400 rating mean once the modules are installed in the server?

It indicates a 4800 MT/s data rate at 1.10V with CL40 latency, delivering the bandwidth the platform expects from registered ECC DDR5.
