NEMIX RAM
Eight 128 GB DDR5 registered ECC modules at 4800 MT/s CL40 1.1 V, validated for Dell PowerEdge R7625
This registered DDR5 memory kit delivers 1TB of capacity across eight 128GB modules. It is built for administrators upgrading the Dell PowerEdge R7625 rack server with ECC protection and 4Rx4 organisation. The kit targets IT teams running virtualisation, database or high-performance computing workloads that demand maximum registered DIMM density.
Modules run at the standard 1.10V DDR5 voltage with a CAS latency of 40 at the rated 4800 MT/s data rate. Registered buffering and on-die ECC help maintain signal integrity and data accuracy under sustained load. The absence of heat spreaders means airflow through the server chassis manages thermals directly on the DRAM packages.
Each module uses the 288-pin RDIMM interface populated with Samsung, Micron or Hynix components selected by the assembler. Registered signalling reduces electrical load on the memory controller, allowing all eight slots to be populated simultaneously. The kit is validated for the Dell PowerEdge R7625 platform; other systems require separate compatibility verification.

Power off the server, open the chassis, align each module with the slot key notch, press firmly until both retention clips click, then verify all eight 128GB modules appear in BIOS before booting the OS.
The modules have no heat spreaders and no moving parts; run periodic memory diagnostics and reseat the 288-pin RDIMMs only if ECC logs report correctable errors on a specific rank.
The DDR5 4800 PC5-38400 bandwidth ceiling is reached before thermal throttling because the registered 4Rx4 modules operate at 1.10V without heat spreaders.
