NEMIX RAM 768GB (6 x 128GB) DDR5 4800 PC5-38400 CL40 1.1V 4Rx4 ECC RDIMM server RAM

Dell PowerEdge R7615 compatible kit

This 768GB kit contains six 128GB DDR5 4800 RDIMM modules built for the Dell PowerEdge R7615 rack server. Registered ECC operation and 4Rx4 organisation provide the data integrity and density required for virtualisation hosts and database tiers. The 1.1V voltage matches the platform's native DDR5 specification. IT teams can populate all twelve slots with two kits for maximum capacity.

Thermals and power in normal use

Registered buffers and on-die ECC logic spread the electrical load across each 128GB module, keeping per-DIMM power modest at the standard 1.1V rail. Passive operation without heat spreaders relies on the server's directed airflow, so acoustic output stays at chassis-fan level. The CL40 latency at 4800 MT/s delivers predictable bandwidth for typical enterprise workloads without elevating memory-controller voltage.

Behaviour under sustained load

Stress testing validates stability when all six modules run continuously at PC5-38400 throughput, ensuring error correction remains active during extended compute jobs. The 4Rx4 rank structure maintains signal integrity across full-rank population, preventing the throttling that can appear with denser unbuffered alternatives. System firmware manages refresh cycles automatically, so performance stays consistent throughout multi-hour processing windows.
