NEMIX RAM 128GB DDR5 4800 CL40 4Rx4 1.1V ECC RDIMM Dell XE8640 memory upgrade

Dell PowerEdge XE8640 upgrade module

This 128GB DDR5 registered DIMM is built for the Dell PowerEdge XE8640 rack server. It delivers ECC protection and a 4Rx4 organisation in a single 288-pin module. The part targets administrators who need maximum capacity per slot without mixing ranks.

Fits XE8640 memory architecture

The module operates at 1.1V and plugs directly into the server's DDR5 RDIMM slots. Registered signalling reduces electrical load on the memory controller, freeing headroom for additional modules. No heat spreader is fitted, so airflow follows the chassis design.

Sustained load behaviour

Rated at 4800 MT/s with CL40 latency, the DIMM maintains throughput during extended compute runs. ECC corrects single-bit errors on the fly, preventing silent data corruption. Major OEM DRAM from Samsung, Micron or Hynix underpins consistent timing under thermal pressure.
