Capacity and Compatibility

This NEMIX RAM kit delivers 512GB of DDR5 server memory across four 128GB modules. It is built for the Supermicro H13SVW-N motherboard and uses the 288-pin RDIMM form factor with registered ECC architecture. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at the rated speed.

Thermals and Power

Each module operates at 1.1V without a heat spreader, relying on the server's directed airflow for cooling. Registered buffering reduces the electrical load on the memory controller when all slots are populated. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

Upgrade Context

This kit replaces smaller or slower DDR5 RDIMM sets when the workload demands maximum registered ECC capacity at 5600MHz. The jump is worth it when your Supermicro H13SVW-N configuration requires full 512GB population with CL46 timing and 2Rx4 organisation. Buyers needing UDIMM or non-ECC modules cannot use this product.

Questions about this item

How do I install the 288-pin RDIMM modules into the Supermicro H13SVW-N and what population step is often missed?

Power down the server, open the chassis, and insert each 128 GB DDR5 RDIMM into the slots specified by the Supermicro H13SVW-N manual in the exact population order; the step most often missed is following that board-specific sequence instead of simply filling the first four slots.

What maintenance or replacement will the 2Rx4 Registered ECC RDIMMs need over their service life?

The modules have no moving parts and require no scheduled maintenance; replacement is only necessary if a DIMM fails, at which point the lifetime replacement warranty covers a direct swap of the defective 128 GB stick.

What limit appears first when the 512 GB kit runs sustained workloads at DDR5-5600?

The registered buffer and ECC logic keep the memory controller stable at full 5600 MT/s speed, so the first practical ceiling is the Supermicro H13SVW-N motherboard's maximum supported capacity and population rules rather than the DIMMs themselves.
