NEMIX RAM 512GB (4x128GB) DDR5 4800 CL40 4Rx4 ECC RDIMM Dell R6625

512GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit delivers 512GB of registered DDR5 memory across four 128GB modules. Each stick runs at 4800 MT/s with CL40 latency at 1.1V. The 4Rx4 organisation and on-die ECC suit Dell PowerEdge R6625 rack servers that require registered DIMMs. Modules ship without heat spreaders and use major OEM DRAM from Samsung, Micron or Hynix.

For Dense In-Memory Workloads, Not Consumer Builds

Database administrators and virtualisation engineers who need maximum capacity per slot in a validated Dell configuration will match this kit to the R6625 qualified-vendor list. Workstations or desktops that accept only unbuffered UDIMMs cannot use registered RDIMMs, so buyers without a compatible server platform should look elsewhere.

4Rx4 Rank Determines Slot Population Limits

The quad-rank 4Rx4 layout means each module presents four logical ranks to the memory controller. Dell R6625 memory population rules cap the total rank count per channel, so the number of DIMMs you can install depends on this rank structure. Verify the server's maximum supported ranks per channel before populating all slots.
