NEMIX RAM DDR5 6400 ECC Registered RDIMM 192GB 12x16GB CL52 1.1V Supermicro H14DSH memory upgrade

192GB DDR5-6400 ECC RDIMM kit for Supermicro H14DSH

This 192GB kit contains twelve 16GB DDR5 6400MHz registered ECC RDIMMs built to the exact 1Rx8, 1.1V, CL52 specification the Supermicro H14DSH memory controller expects. It is intended for server administrators who need to populate every slot at full rated speed with registered modules that include on-die error correction. Buyers who require unbuffered UDIMMs, SODIMMs, or a different voltage, rank, or capacity configuration cannot use this kit.

Check motherboard manual for population rules

Before ordering, consult the Supermicro H14DSH manual for the approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements for DDR5-6400 operation. The board requires 288-pin registered RDIMMs; UDIMMs or SODIMMs will not fit or function. Verify that your chassis and CPU configuration allow all twelve slots to be populated and that the memory controller can address the full 192GB at the rated frequency.

Kit delivers matched modules for full-slot stability

The twelve modules are packaged as a single validated kit so every DIMM shares identical timing, voltage, and rank characteristics. This matching lets the registered architecture offload the memory controller cleanly when all slots are filled, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. No heat spreaders are included, and no additional software or accessories are bundled.
