384GB DDR5 RDIMM kit for Dell PowerEdge R6625

This NEMIX RAM kit delivers 384GB of DDR5 server memory across twelve 128GB registered DIMMs. It is built for IT professionals upgrading a Dell PowerEdge R6625 rack server. The modules are stress-tested for stability in mission-critical environments.

4Rx4 registered ECC at CL40 1.10V

Each 288-pin module runs at 4800 MT/s (PC5-38400) with a CAS latency of 40 and operates at 1.10 volts. The 4Rx4 organisation and registered ECC design provide the error correction and signal integrity required by the qualified platform. Major OEM DRAM from Samsung, Micron or Hynix is used.

Twelve-module kit simplifies large-capacity

The 12x128GB configuration fills the memory subsystem in a single purchase, removing the need to source individual sticks. No heat spreaders are fitted, matching the factory form factor for the validated server. Lifetime replacement warranty and US-based IT support back the installation.

Questions about this item

What does the 4800 MT/s rating mean once the modules are installed in a Dell PowerEdge R6625?

The kit runs at DDR5 4800 (PC5 38400) with CL40 latency at 1.10 V, delivering the rated throughput when the server's memory controller is configured for that speed.

How does the 288-pin DDR5 RDIMM interface limit the usable bandwidth in this server?

The registered 288-pin DDR5 RDIMM form factor connects through the R6625's memory channels, capping per-module bandwidth at the DDR5 4800 spec.

What physical space and slot layout does the 12-module kit require in the R6625 chassis?

Twelve 288-pin RDIMM slots must be populated, so the server needs all 12 DIMM sockets free and enough clearance for the full-height modules.
