  • 2TB capacity scales memory-heavy workloads with sixteen 128GB modules
  • DDR5 4800 speed delivers rated bandwidth at 1.1V operating voltage
  • CL40 latency and 2Rx4 rank match the memory controller's exact timing requirements
  • Registered ECC architecture corrects single-bit errors while buffering every slot at full population
  • 288-pin RDIMM form factor verified for Supermicro H14SST-G motherboard compatibility

Exact-match server kit

This 2 TB kit delivers 16 modules of 128 GB DDR5 ECC RDIMM memory tuned for the Supermicro H14SST-G motherboard. Each DIMM runs at 4800 MT/s with CL40 timing at 1.1 V using a 2Rx4 registered layout. The modules are built with major OEM chips and carry a lifetime replacement warranty.

Registered ECC architecture

Registered buffering lets the memory controller drive all 16 slots at full capacity while ECC corrects single-bit errors in real time. The 288-pin RDIMM form factor matches the board's native slot design and population rules. No heat spreaders are fitted, so airflow clearance follows the chassis specification.

Capacity leap for dense workloads

Moving from smaller RDIMM sets to this 16-module configuration unlocks the full 2 TB ceiling the platform supports. The jump is worth it when virtualization, in-memory databases or large-scale analytics demand maximum rank density per channel. Buyers needing fewer than 16 slots or lower total capacity should choose a smaller kit.

Questions about this item

What is the maximum sustained capacity this 16-module kit is validated for on the Supermicro H14SST-G?

The kit provides 2 TB total capacity using sixteen 128 GB DDR5 RDIMMs, matching the board's fully populated limit at 4800 MT/s.

How much power does each module draw and what cooling is needed when all slots are filled 24/7?

Each RDIMM runs at 1.1 V with no heat spreader; the registered design offloads the memory controller so the board's standard airflow handles sustained loads.

Which motherboard feature must be present for these registered ECC modules to be recognised at full speed?

The Supermicro H14SST-G must provide 288-pin DDR5 RDIMM slots with registered-ECC support; UDIMM or SODIMM sockets will not work.
