Server Memory Kit for Supermicro H13SST-GC

This 1.5TB kit contains twelve 128GB DDR5 RDIMM modules built for the Supermicro H13SST-GC motherboard. Registered ECC architecture offloads the memory controller and corrects single-bit errors to keep production workloads stable at full capacity.

Ideal for Fully Populated Server Slots

Suits administrators upgrading a Supermicro H13SST-GC to its maximum supported memory with matched 2Rx4 modules. Builders using consumer boards, UDIMM slots, or systems that cannot register 12 modules at 6400MHz should choose different memory.

6400MHz CL52 Registered ECC Specification

The kit runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V across all 288-pin RDIMM slots. This exact speed, timing, voltage, and registered ECC combination is what the memory controller expects for error-free operation.

Highlights

  • 5TB total capacity from twelve 128GB modules
  • DDR5 6400 speed with CL52 latency at 1.1V
  • Registered ECC design corrects single-bit errors automatically
  • 2Rx4 organisation enables full population on supported boards
  • Exact-match kit verified for Supermicro H13SST-GC motherboard

Questions about this item

Does the 1.5TB kit include all 12 modules or do I need to buy additional DIMMs?

The kit contains twelve 128GB DDR5 RDIMM modules for a total of 1.5TB, so no extra DIMMs are required to reach the stated capacity.

Should I choose this 12x128GB CL52 kit or a different capacity for my Supermicro H13SST-GC?

This 1.5TB 12x128GB kit matches the board's 288-pin RDIMM slot count and registered ECC requirement; select it when you need the maximum supported capacity at DDR5 6400 speed.

Will the advertised DDR5 6400 speed run at 6400 MT/s once installed in the H13SST-GC?

The modules are spec-matched to the motherboard's memory controller, so they are recognised at full capacity and operate at the rated DDR5 6400 (PC5-51200) speed with CL52 latency.
