NEMIX RAM DDR5 512GB 4x128GB 6400MHz CL52 1.1V ECC RDIMM Supermicro H13SSW

Purpose-built server memory kit

This NEMIX RAM kit delivers 512 GB of DDR5 ECC registered memory in four 128 GB modules. It is built for administrators who need the exact rank, voltage and timing the Supermicro H13SSW memory controller expects so the system recognises full capacity at rated speed. The 2Rx4 registered design offloads the controller, allowing every slot to run fully populated while on-die ECC corrects single-bit errors before they reach production workloads.

Upgrade path and fitment

The kit replaces lower-capacity or slower DDR5 RDIMMs when your workload demands maximum registered memory per channel at 6400 MT/s. The jump is worth it when the board’s population rules call for 2Rx4 modules at 1.1 V and you need the full 512 GB configuration without mixing ranks or voltages. Verify the motherboard manual for approved DIMM population order and supported capacities before purchase.

DDR5 registered DIMM limits

DDR5 RDIMMs at 6400 MT/s with CL52 latency and 1.1 V operation are bound by the memory controller’s maximum supported frequency and rank-per-channel limits. Registered buffering reduces electrical load but does not override the board’s native population rules or maximum density per slot. The 288-pin form factor fits only DDR5 RDIMM slots; it will not work in UDIMM or SODIMM sockets.
