Show 30 more configurations
  • 256 GB total capacity for large workloads with 8 modules of 32 GB each
  • DDR5 4800 speed matches the server memory controller for rated performance
  • CL40 latency and 1.1 V voltage meet exact platform timing requirements
  • Registered ECC design corrects single-bit errors and supports full population stability
  • 288-pin RDIMM form factor verified for Supermicro H14SST-G motherboard compatibility

Exact-match server upgrade

This 256GB kit delivers eight 32GB DDR5 4800 RDIMM modules built to the Supermicro H14SST-G memory controller specification. Registered ECC architecture with CL40 timing and 1.10V operation lets every slot run fully populated at rated speed.

2Rx8 Registered ECC at DDR5 4800

The 2Rx8 rank structure, 288-pin RDIMM form factor and on-die ECC are the single specification that decides fitment; the board only accepts this exact combination. Any UDIMM, SODIMM or different rank configuration will not be recognised by the memory controller.

Straightforward slot installation

Modules key into the 288-pin DIMM sockets in the population order shown in the motherboard manual; no cables, jumpers or tools are required. The most common issue is inserting DIMMs in the wrong slot sequence, which prevents the system from posting at full capacity.

Questions about this item

What does the 4800 MT/s rating deliver when all eight DIMMs are installed?

The kit runs at DDR5-4800 across all 256 GB when fully populated, giving the memory controller its rated bandwidth without downclocking.

How does the registered ECC design affect signal integrity on the Supermicro H14SST-G?

Registered buffering reduces electrical load on the memory bus so every slot stays stable at full speed, while ECC corrects single-bit errors before they cause data corruption.

Will these 288-pin RDIMMs physically seat in the H14SST-G memory slots?

Yes — the modules use the standard 288-pin DDR5 RDIMM form factor required by the board, matching its keying and mechanical dimensions.
