NEMIX RAM
Eight-module kit provides 128 GB of DDR5 ECC registered memory at 4800 MT/s with CL40 latency for the ASUS RS720-E11-RS24U server
This 128GB kit comprises eight 16GB DDR5-4800 registered DIMMs built for the ASUS RS720-E11-RS24U 2U dual-socket server. ECC and registered signalling protect data integrity in mission-critical workloads. It targets IT teams upgrading memory capacity in that specific platform.
Each module uses a single-rank 1Rx8 layout with Samsung, Micron or Hynix chips running at 1.10V. The registered buffer reduces electrical load on the memory controller, allowing all eight slots to be populated without signal degradation. No heat spreaders are fitted, so airflow in the 2U chassis must handle cooling.
The DDR5-4800 CL40 JEDEC standard sets the baseline bandwidth and latency for this registered ECC kit. Registered modules add one clock cycle of address/command delay compared with unbuffered DIMMs. Mixed-rank or mixed-speed configurations are not supported by this kit, so all slots must use identical modules.

The modules have no moving parts and no heat spreaders, so no routine maintenance is required.
The registered DDR5 4800 CL40 timing at 1.10 V sets the sustained throughput ceiling.
Each 1Rx8 module operates at 1.10 V without a heat spreader, keeping thermal output low for server airflow.
