  • 384 GB total capacity from eight 48 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency delivers rated bandwidth without tuning
  • Registered ECC design offloads the controller and corrects single-bit errors on the fly
  • 1 V operation matches the platform specification for stable full-population runs
  • 288-pin RDIMM form factor verified for Supermicro H14SHM motherboard compatibility

Supermicro H14SHM upgrade kit

This 384GB kit contains eight 48GB DDR5 registered ECC RDIMMs validated for the Supermicro H14SHM motherboard. Each module runs at 4800 MT/s with CL40 latency at 1.1V, matching the board's memory-controller requirements exactly.

Registered ECC requirement

This kit only works in systems that accept 288-pin DDR5 registered ECC RDIMMs; it will not function in desktop boards or workstations needing unbuffered UDIMMs. Servers requiring a different rank configuration or voltage should verify their manual before ordering.

Eight-module population

The kit fills eight DIMM slots with 2Rx8 registered modules so the memory controller sees the full 384GB at rated speed. Boards with fewer slots or a different population rule cannot use this configuration.

Questions about this item

How do I install the eight 48GB DDR5 RDIMM modules in the Supermicro H14SHM and which population step is most often missed?

Install all eight 288-pin RDIMMs following the motherboard manual's exact slot order; the step most often missed is verifying the required population sequence for full 384GB recognition at DDR5-4800.

What maintenance or replacement will the NEMIX RAM 384GB DDR5 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and a module is replaced only if it develops uncorrectable faults, covered by the lifetime replacement warranty.

What is the first limit that appears when the 384GB DDR5-4800 CL40 1.1V registered kit runs sustained workloads?

The registered architecture and ECC keep every slot stable at rated speed, so the first limit is the DDR5-4800 bandwidth ceiling of the memory controller itself.
