Exact-match upgrade for Supermicro H13SST-GC

This 288GB kit contains six 48GB DDR5 RDIMM modules built to the exact rank, voltage and timing the motherboard expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. It is intended for administrators who need maximum capacity on this specific platform.

DDR5 6400 registered ECC limits

The modules operate at DDR5 6400 (PC5 51200) with CL52 latency at 1.1V. Registered buffering reduces electrical load on the memory controller so all six slots can be filled without signal degradation. ECC provides error detection and correction, but the registered design means these DIMMs will not work in consumer boards that require unbuffered UDIMMs.

Six-module RDIMM kit, no heat spreaders

Each 288-pin DIMM uses major OEM DRAM chips and omits a heat spreader to fit tight server DIMM spacing. The 2Rx8 organisation matches the board's population rules for full-capacity operation. Buyers who need a different capacity per module or a UDIMM form factor should look elsewhere.

Highlights

  • 288 GB total capacity from six 48 GB modules
  • DDR5 6400 speed with CL52 latency for rated performance
  • Registered ECC design corrects single-bit errors automatically
  • 1 V operation matches the server memory controller spec
  • Verified fitment for Supermicro H13SST-GC motherboard

Questions about this item

Should I choose the 6×48 GB kit or a different capacity for my Supermicro H13SST-GC?

The kit provides 288 GB total across six 48 GB RDIMMs, matching the board's DDR5-6400 registered ECC specification; populate all six slots following the motherboard manual's population order for full capacity at rated speed.

What does the DDR5-6400 rating deliver once installed in the server?

The modules run at 6400 MT/s with CL52 latency at 1.1 V, giving the memory controller the exact timing and voltage it expects so the system recognises the full 288 GB and operates at the rated data rate.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered architecture buffers address and command signals, allowing all six slots to run fully populated at 6400 MT/s, while on-die ECC corrects single-bit errors on the fly to prevent silent data corruption.
