NEMIX RAM 256GB (2x128GB) DDR5 4800 ECC RDIMM Dell R660

256GB DDR5 RDIMM kit

This kit provides 256GB of DDR5 server memory in two 128GB registered modules. It is built for the Dell PowerEdge R660 and other platforms that accept 288-pin ECC RDIMMs. IT teams use it to expand capacity for virtualisation, databases and memory-intensive workloads.

4800 MT/s with CL40 latency

Each module runs at 4800 MT/s (PC5-38400) with a CAS latency of 40 at 1.10V. The 4Rx4 organisation delivers high density per slot, so two modules fill two DIMM positions with 256GB total. Workloads that exceed this capacity will need additional slots or higher-density modules.

DDR5 ECC registered interface

The DDR5 ECC registered interface adds on-die error correction and a register to reduce electrical load on the memory bus. This improves signal integrity at speed but requires a motherboard chipset that supports registered DDR5. Systems limited to unbuffered memory or earlier DDR generations cannot use these modules.
