Server Memory Kit

This NEMIX RAM kit provides 128GB of DDR5 ECC Registered memory across eight 16GB modules. It is built for administrators upgrading compatible Dell PowerEdge rack servers that require registered DIMMs with error correction. The kit suits virtualization hosts and database workloads needing high capacity per channel. Buyers needing unbuffered DIMMs or non-ECC memory for consumer platforms cannot use this product.

Thermals and Power

Each module operates at 1.10V, the standard voltage for DDR5 4800, helping to limit power draw under load. The modules have no heat spreader, so airflow across the DIMM slots determines operating temperature in a populated chassis. Registered buffering adds a clock cycle of latency but reduces electrical load on the memory controller. Systems without forced airflow over the memory region may see higher temperatures at sustained throughput.

Build and Connectors

The 288-pin RDIMM form factor fits standard DDR5 server slots keyed for registered modules. Eight modules fill multiple channels on supported motherboards such as the Dell PowerEdge R760xd2 referenced in the compatibility data. Major OEM DRAM from Samsung, Micron or Hynix is used depending on supply. Mixing these registered ECC modules with unbuffered or consumer memory is not supported by the platform.

Questions about this item

How are the eight 16 GB DDR5 RDIMMs installed in a Dell PowerEdge R760xd2, and what step is commonly missed?

Populate all eight slots following the server's memory-channel sequence, then run the BIOS memory-configuration utility so the registered ECC modules initialise at 4800 MT/s with CL40 timing.

What maintenance or replacement will this 128 GB DDR5 ECC kit require over its service life?

No routine maintenance is needed; if a module fails the lifetime replacement warranty covers a direct swap of the defective 16 GB RDIMM.

What limit appears first when the kit runs sustained workloads at 4800 MT/s?

The registered DDR5 interface caps throughput at PC5-38400, so bandwidth saturates before the 1.10 V thermal envelope becomes a constraint.
