NEMIX RAM 512GB (8x64GB) DDR5 4800 ECC RDIMM CL40 Supermicro H13SSW memory upgrade

Exact-Match Server Upgrade

This 512GB kit contains eight 64GB DDR5 RDIMM modules built to the precise specification the Supermicro H13SSW motherboard expects. Registered ECC architecture and 2Rx4 organisation allow full-slot population at rated speed without overloading the memory controller. System administrators who need maximum supported capacity for virtualisation or database workloads can install the kit and have it recognised immediately. Buyers using consumer boards or UDIMM-only platforms cannot use this memory.

Thermals and Power Draw

Each module operates at 1.10V with no heat spreader, relying on the server chassis airflow to manage thermals under sustained load. The registered design reduces electrical loading on the memory bus, helping keep system power draw predictable even when all eight slots are populated. CL40 latency at DDR5-4800 delivers the bandwidth the platform specifies without requiring additional voltage headroom. Environments without directed server-class airflow should verify thermal margins before deploying fully populated.

Build Integration

The 288-pin RDIMM form factor fits only motherboards wired for registered DDR5; it will not seat in UDIMM or SODIMM slots. Population order follows the H13SSW manual, so installers must populate channels in the approved sequence to achieve 512GB capacity. Eight modules occupy every DIMM slot, leaving no room for future expansion on this board. Confirm the firmware revision supports the full kit before installation.
