NEMIX RAM 2TB (16x128GB) DDR5 4800 CL40 1.1V 4Rx4 ECC RDIMM memory upgrade

2TB DDR5 ECC RDIMM kit for SuperMicro servers

This 2 TB memory kit contains sixteen 128 GB DDR5 4800 RDIMMs built for SuperMicro GPU SuperServer models including the SYS-821GE-TNHR SYS-821GV-TNR and SYS-421GE-TNRT. Registered ECC modules with a 4Rx4 organisation provide the error correction and signal integrity required by dense multi-socket platforms. The kit targets administrators who need maximum capacity in validated configurations.

DDR5 4800 registered interface limits

The DDR5 4800 PC5-38400 standard sets the baseline data rate and timing envelope for these modules. CL40 latency and 1.10 V operation are defined by the JEDEC specification for this speed grade. Registered buffering reduces electrical load on the memory controller but adds one cycle of command latency. Systems must support DDR5 RDIMM topology and 4Rx4 rank structure to recognise the full 2 TB capacity.

Capacity headroom for dense workloads

Sixteen 128 GB modules fill every DIMM slot on compatible SuperMicro boards delivering 2 TB of addressable memory. This density suits large virtualisation clusters in-memory databases and GPU-accelerated compute where each thread requires substantial local data. Workloads that exceed 2 TB or require higher memory bandwidth than 4800 MT/s will need a platform with faster DDR5 speeds or additional memory controllers.
