NEMIX RAM 128GB 2x64GB DDR5 4800 CL40 ECC RDIMM Supermicro H13SVW-NT-OS2 memory upgrade

Server memory kit for Supermicro H13SVW-NT-OS2

This 128GB kit contains two 64GB DDR5 4800 RDIMM modules built to the exact rank, voltage and timing the board expects. Registered ECC architecture lets every slot run fully populated while correcting single-bit errors on the fly. It targets administrators who need maximum capacity on this specific platform without trial-and-error compatibility testing.

Upgrade from smaller or slower DDR5 RDIMMs

Replacing lower-capacity DDR5 modules with this 2x64GB kit doubles usable memory per channel and keeps the memory controller at its rated 4800 speed. The jump is worth it when workloads exceed current capacity or when mixed-rank populations force downclocking. Buyers who need more than 128GB per board or who run consumer UDIMM slots cannot use this kit.

Install by following the motherboard manual

The 288-pin RDIMM form factor seats only in registered DIMM slots and must be populated in the order the manual specifies. Common issues are mixing ranks across channels, skipping required population sequences, or forgetting to enable ECC in BIOS. No heat spreader is included, so airflow across the modules must be adequate for sustained server loads.
