NEMIX RAM DDR5 6400 ECC Registered RDIMM 384GB (6x64GB) Supermicro H14DSH memory upgrade

Exact-match DDR5 RDIMM kit for Supermicro H14DSH

This 384 GB kit contains six 64 GB DDR5 6400 modules built to the PC5-51200 standard. Each stick is a 2Rx4 Registered ECC RDIMM running at 1.10 V with CL52 latency. The 288-pin form factor matches the H14DSH memory slots exactly, so the server recognises the full capacity at rated speed without manual tuning.

Fits the H14DSH memory rules and frees every slot

Registered buffering offloads the memory controller, allowing all channels to stay fully populated while ECC corrects single-bit errors on the fly. The modules ship without heat spreaders, relying on the chassis airflow the H14DSH design already provides. Install them in the population order listed in the motherboard manual and the system posts at DDR5 6400 without further configuration.

Replaces partial or mixed-capacity kits that limit

If the board currently runs fewer than six DIMMs or mixes ranks, this kit restores balanced channels and eliminates the throughput penalty of uneven population. The jump is worth it when workloads need the full 384 GB address space and the stability of registered ECC at native DDR5 6400. Builders who need a different total capacity or a UDIMM form factor should look elsewhere.
