NEMIX RAM 256GB (2x128GB) DDR5 6400 CL52 1.1V 2Rx4 ECC RDIMM memory upgrade for Supermicro H13SSW

Exact-Match Upgrade Kit

This 256GB kit delivers two 128GB DDR5 RDIMMs built to the Supermicro H13SSW motherboard's exact specifications. Registered ECC architecture ensures the memory controller recognises every module at full rated speed without manual tuning. The 1.1V operating voltage matches the platform's native requirement for stable operation.

256GB Capacity and Registered Headroom

With 256GB across two slots the kit supports memory-intensive workloads such as virtualisation clusters, in-memory databases and large-scale rendering farms. Registered buffering offloads the controller so every populated slot runs at DDR5-6400 CL52 without signal degradation. ECC corrects single-bit errors on the fly to prevent silent data corruption in production environments.

Replaces Mismatched or Lower-Capacity Modules

The kit upgrades systems running slower DDR5 speeds, smaller densities or unbuffered DIMMs that the H13SSW cannot fully populate. Moving to matched 2Rx4 registered ECC modules unlocks the board's maximum supported capacity and rated bandwidth in a single step. The jump is worth it when current memory limits container density, database caching or compile throughput.
