NEMIX RAM
Eight 128 GB DDR5 ECC registered DIMMs deliver 1 TB at 4800 MT/s CL40 for ASUS RS720-E11-RS12U servers
This 1 TB kit contains eight 128 GB DDR5 4800 CL40 ECC registered DIMMs validated for the ASUS RS720-E11-RS12U 2U dual-socket server. It targets IT teams who need maximum memory capacity in that specific platform without mixing module sizes.
Registered buffering and on-die ECC let the memory controller address all eight quad-rank modules while correcting single-bit errors, which is required for the sustained workloads this server runs. The 1.1 V operating voltage matches the platform specification.
The PC5-38400 data rate is the baseline DDR5 speed, so bandwidth scales only with channel count and rank population rather than higher clock options. Builders who need faster memory transfer rates must select a platform qualified for higher DDR5 speeds.

The modules are standard DDR5 ECC RDIMMs with no firmware; they are solid-state and have no scheduled replacement interval.
Each module operates at 1.1 V with a CL40 latency; sustained load is limited by the server’s memory-controller thermal envelope rather than the DIMMs themselves.
The modules have no heat spreaders and draw 1.1 V each, so they add minimal heat and zero acoustic noise; system fans handle any extra thermal load.
